The National Center for Health Statistics (NCHS) of the Centers for Disease     
Control and Prevention (CDC) collects, analyzes, and disseminates data on       
the health status of U.S. residents.  The results of surveys, analyses, and     
studies are made known through a number of data release mechanisms              
including publications, mainframe computer data files, CD-ROMs (Search and      
Retrieval Software, Statistical Export and Tabulation System (SETS)), and the   
Internet (http://www.cdc.gov/nchswww/nchshome.htm).                             
                                                                                
The National Health and Nutrition Examination Survey (NHANES) is a periodic     
survey conducted by NCHS.  The third National Health and Nutrition              
Examination Survey (NHANES III), conducted from 1988 through 1994, was the      
seventh in a series of these surveys based on a complex, multi-stage sample     
plan.  It was designed to provide national estimates of the health and          
nutritional status of the United States' civilian, noninstitutionalized         
population aged two months and older.                                           
                                                                                
Data from NHANES III are being released in five public release data files:

data files.  The general overview includes five sections.  The first            
section, entitled "Guidelines for Data Users," contains important information   
about the use of the data files.  The second section, "Survey Description,"     
is a brief overview of the survey plan and operation.  The third section,       
"Sample Design and Analysis Guidelines," describes some technical aspects of    
the sampling plan and discusses some analytic issues particularly related to    
the use of data from complex sample surveys.  The "Data Preparation and         
Processing Procedures" section describes the editing conventions and the        
codes used to represent the data.  The last and fifth section, "General         
References," includes a reference list for the survey overview sections of      
the document.

     Examination Survey, 1988-94, (NCHS, 1994; U.S. DHHS, 1996) provides an     
     overview of the survey and includes copies of the survey forms.

     the NHANES III Reference Manuals and Reports CD-ROM (U.S. DHHS, 1996)      
     discuss the reasons that sample weights and the complex survey design      
     should be taken into account when conducting any analysis.                 
                                                                                
o    Instruction manuals, laboratory procedures, and other NHANES III           
     reference manuals on the NHANES III Reference Manuals and Reports          
     CD-ROM(U.S. DHHS, 1996) are also available for further information on      
     the details of the survey.                                                 
                                                                                
                                                                                
Analytic Data Set Preparation                                                   
                                                                                
o    Most NHANES III survey design and demographic variables are found only     
     on the Adult and Youth Household Data Files.  In preparing a data set      
     for analysis, other data files must be merged with either or both of       
     these files to obtain many important analytic variables.                   
                                                                                
o    All of the NHANES III public use data files are linked with the common     
     survey participant identification number (SEQN).  Merging information      
     from multiple NHANES III data files using this variable ensures that       
     the appropriate information for each survey participant is linked          
     correctly.                                                                 
                                                                                
o    NHANES III public use data files do not have the same number of            
     records on each file.  The Household Questionnaire Files (divided into     
     two files, Adult and Youth) contain more records than the Examination      
     Data File because not everyone who was interviewed completed the           
     examination. The Laboratory Data File contains data only for persons       
     aged one year and older.  The Individual Foods Data File based on the      
     dietary recall has multiple records for each person rather than the one    
     record per sample person contained in the other data files.                
                                                                                
o    For each data file, SAS program code with standard variable names and      
     labels is provided as separate text files on the CD-ROM that contains      
     the data files.  This SAS program code can be used to create a SAS         
     data set from the data file.                                               
                                                                                
o    Modifications were made to items in the questionnaires, laboratory,        
     and examination components over the course of the survey; as a result,     
     data may not be available for certain variables for the full six years.    
     In addition, variables may differ by phase since some changes were         
     implemented between phases.  Users are encouraged to read the Notes        
     sections of this document carefully for information about changes.         
                                                                                
o    Extremely high and low values have been verified whenever possible,        
     and numerous consistency checks have been performed.  Nonetheless, users   
     should examine the range and frequency of values before analyzing          
     data.                                                                      
                                                                               
o    Some data were not ready for release at the time of this publication       
     due to continued processing of the data or analysis of laboratory          
     specimens.  A listing of those data are available in the general           
     information section of each data file.                                     
                                                                                
o    Confidential and administrative data are not being released to the         
     public.  Additionally, some variables have been recoded to help            
     protect the confidentiality of the survey participants.  For example,      
     all age-related variables were recoded to 90+ years for persons who were   
     90 years of age and older.                                                 
                                                                                
o    Some variable names may differ from those used in the Phase 1 NHANES       
     III Provisional Data Release and some variables included in the Phase 1    
     provisional release may not appear on these files.                         
                                                                                
o    Although the data files have been edited carefully, errors may be          
     detected.  Please notify NCHS staff (301-436-8500) of any errors in        
     the data file or the documentation.                                        
                                                                                
                                                                                
                                                                               
Analytic Considerations                                                         
                                                                                
o    NHANES III (1988-94) was designed so that the survey's first three         
     years, 1988-91, its last three years, 1991-94, and the entire six          
     years were national probability samples.  Analysts are encouraged to use   
     all six years of survey results.                                           
                                                                                
o    Sample weights are available for analyzing NHANES III data.  One of        
     the following three sample weights will be appropriate for nearly all      
     analyses:  interviewed sample final weight (WTPFQX6), examined sample      
     final weight (WTPFEX6), and mobile examination center (MEC)- and           
     home-examined sample final weight (WTPFHX6).  Choosing which of these      
     sample weights to use in any analysis depends on the variables being       
     used.  A good rule of thumb is to use "the least common denominator"       
     approach.  In this approach, the user checks the variables of              
     interest.  The variable that was collected on the smallest number of       
     persons is the "least common denominator," and the sample weight that      
     applies to that variable is the appropriate one to use for that            
     analysis.  For more detailed information, see the Analytic and Reporting   
     Guidelines for NHANES III (U.S. DHHS, 1996).

The third National Health and Nutrition Examination Survey (NHANES III) was     
the seventh in a series of large health examination surveys conducted in        
the United States beginning in 1960.  Three of these surveys, the National      
Health Examination Surveys (NHES), were conducted in the 1960's (NCHS, 1965;    
NCHS, 1967; NCHS, 1969).  In 1970, an expanded nutrition component was added    
to provide data with which to assess nutritional status and dietary             
practices, and the name was changed to the National Health and Nutrition        
Examination Survey (Miller, 1973; Engel, 1978; McDowell, 1981).  A special      
survey of Hispanic populations in the United States was conducted during        
1982-1984 (NCHS, 1985).                                                         
                                                                                
The general structure of the NHANES III sample design was similar to that       
of the previous NHANES.  All of the surveys used complex, multi-stage,          
stratified, clustered samples of civilian, noninstitutionalized                 
populations.  NHANES III was the first NHANES without an upper age limit; in    
fact, the age range for the survey was two months and older.  A home            
examination option was employed for the first time in order to obtain           
examination data for very young children and for elderly persons who were       
unable to visit the mobile examination center (MEC).  The home examination      
included only a subset of the components used in the full MEC examination       
since it would have been difficult to collect some types of data in a home      
setting.  A detailed description of design specifications and copies of the     
data collection forms can be found in the Plan and Operation of the Third       
National Health and Nutrition Examination Survey, 1988-1994 (NCHS, 1994; U.S.   
DHHS, 1996).                                                                    
                                                                                
NHANES III was conducted from October 1988 through October 1994 in two          
phases, each of which comprised a national probability sample.  The first       
phase was conducted from October 18, 1988, through October 24, 1991, at 44      
locations.  The second phase was conducted from September 20, 1991, through     
October 15, 1994, at 45 different locations.  In NHANES III, 39,695 persons     
were selected over the six years; of those, 33,994 (86%) were interviewed       
in their homes.  All interviewed persons were invited to the MEC for a          
medical examination.  Seventy-eight percent (30,818) of the selected persons    
were examined in the MEC, and an additional 493 persons were given a special,   
limited examination in their homes.                                             
                                                                                
Data collection began with a household interview.  Several questionnaires       
were administered in the household:  Household Screener Questionnaire,          
Family Questionnaire, Household Adult Questionnaire, and Household Youth        
Questionnaire.                                                                  
                                                                                
At the MEC, an examination was performed, and five automated questionnaires     
or interviews were administered:  MEC Adult Questionnaire, MEC Youth            
Questionnaire, MEC Proxy Questionnaire, 24-Hour Dietary Recall, and Dietary     
Food Frequency (ages 12-16 years).  The health examination component            
included a variety of tests and procedures.  The examinee's age at the time     
of the interview and other factors determined which procedures were             
administered.  Blood and urine specimens were obtained, and a number of tests   
and measurements were performed including body measurements, spirometry,        
fundus photography, x-rays, electrocardiography, allergy and glucose            
tolerance tests, and ultrasonography.  Measurements were taken of bone          
density, hearing, and physical, cognitive, and central nervous system           
functions.  A physician performed a limited standardized medical examination    
and a dentist performed a standardized dental examination.  While some of the   
blood and urine analyses were performed in the MEC laboratory, most analyses    
were conducted elsewhere by contract laboratories.                              
                                                                                
                                                                               
A home examination was conducted for those sample persons aged 2-11 months      
and aged 20 years or older who were unable to visit the mobile examination      
center.  The home examination consisted of an abbreviated version of the        
tests and interviews performed in the MEC.  Depending on age of the sample      
person, the components included body measurements, blood pressure,              
spirometry, venipuncture, physical function evaluation, and a questionnaire     
to inquire about infant feeding, selected health conditions, cognitive          
function, tobacco use, and reproductive history.

Sample Design                                                                   
                                                                                
The general structure of the NHANES III sample design is the same as that       
of the previous NHANES.  Each of these surveys used a stratified, multi-stage   
probability design.  The major design parameters of the two previous NHANES     
and the special Hispanic HANES, as well as NHANES III, have been previously     
summarized (Miller, 1973; McDowell, 1981; NCHS, 1985; NCHS, 1994).  The         
NHANES III sample was designed to be self-weighting within a primary            
sampling unit (PSU) for subdomains (age, sex, and race-ethnic groups).  While   
the sample was fairly close to self-weighting nationally for each of these      
subdomain groups, it was not representative of the total population, which      
includes institutionalized, non-civilian persons that were outside the          
scope of the survey.                                                            
                                                                                
The NHANES III sample represented the total civilian, noninstitutionalized      
population, two months of age or over, in the 50 states and the District of     
Columbia of the United States.  The first stage of the design consisted of      
selecting a sample of 81 PSU's that were mostly individual counties.  In a      
few cases, adjacent counties were combined to keep PSU's above a minimum        
population size.  The PSU's were stratified and selected with probability       
proportional to size (PPS).  Thirteen large counties (strata) were chosen       
with certainty (probability of one).  For operational reasons, these 13         
certainty PSU's were divided into 21 survey locations.  After the 13            
certainty strata were designated, the remaining PSU's in the United States      
were grouped into 34 strata, and two PSU's were selected per stratum (68        
survey locations).  The selection was done with PPS and without                 
replacement.  The NHANES III sample therefore consists of 81 PSU's or 89        
locations.                                                                      
                                                                                
The 89 locations were randomly divided into two groups, one for each phase.     
The first group consisted of 44 and the other of 45 locations.  One set         
of PSU's was allocated to the first three-year survey period (1988-91) and      
the other set to the second three-year period (1991-94).  Therefore,            
unbiased estimates (from the point of view of sample selection) of health and   
nutrition characteristics can be independently produced for both Phase 1        
and Phase 2 as well as for both phases combined.                                
                                                                                
For most of the sample, the second stage of the design consisted of area        
segments composed of city or suburban blocks, combinations of blocks, or        
other area segments in places where block statistics were not produced in       
the 1980 Census.  In the first phase of NHANES III, the area segments were      
used only for a sample of persons who lived in housing units built before       
1980.  For units built in 1980 and later, the second stage consisted of sets    
of addresses selected from building permits issued in 1980 or later.  These     
are referred to as "new construction segments."  In the second phase, 1990      
Census data and maps were used to define the area segments.  Because the        
second phase followed within a few years of the 1990 Census, new construction   
did not account for a significant part of the sample, and the entire sample     
came from the area segments.                                                    
                                                                                
                                                                               
The third stage of sample selection consisted of households and certain         
types of group quarters, such as dormitories.  All households and eligible      
group quarters in the sample segments were listed, and a subsample was          
designated for screening to identify potential sample persons.  The             
subsampling rates enabled production of a national, approximately               
equal-probability sample of households in most of the United States with        
higher rates for the geographic strata with high Mexican-American               
populations.  Within each geographic stratum, there was a nearly                
equal-probability sample of households across all 89 stands.                    
                                                                                
Persons within the sample of households or group quarters were the fourth       
stage of sample selection.  All eligible members within a household were        
listed, and a subsample of individuals was selected based on sex, age, and      
race or ethnicity.  The definitions of the sex, age, race or ethnic             
classes, subsampling rates, and designation of potential sample persons         
within screened households were developed to provide approximately              
self-weighting samples for each subdomain within geographic strata and at the   
same time to maximize the average number of sample persons per sample           
household.  Previous NHANES indicated that this increased the overall           
participation rate.  Although the exact sample sizes were not known until       
data collection was completed, estimates were made.  Below is a summary of      
the sample sizes for the full six-year NHANES III at each stage of selection:   
                                                                                
Number of PSU's                                  81                             
Number of stands (survey locations)              89                             
Number of segments                               2,144                          
Number of households screened                    93,653                         
Number of households with sample persons         19,528                         
Number of designated sample persons              39,695                         
Number of interviewed sample persons             33,994                         
Number of MEC-examined sample persons            30,818                         
Number of home-examined sample persons           493                            
                                                                                
More detailed information on the sample design and weighting and estimation     
procedures for NHANES III can be found in the Plan and Operation of the         
Third National Health and Nutrition Examination Survey, 1988-94 (NCHS, 1994;    
U.S. DHHS, 1996) and in the Analytic and Reporting Guidelines: Third National   
Health and Nutrition Examination Survey (NHANES III), 1988-94 (U.S. DHHS,       
1996).                                                                          
                                                                                
Analysis Guidelines                                                             
                                                                                
Because of the complex survey design used in NHANES III, traditional            
methods of statistical analysis based on the assumption of a simple random      
sample are not applicable.  Detailed descriptions of this issue and possible    
analytic methods for analyzing NHANES data have been described earlier (NCHS,   
1985; Yetley, 1987; Landis, 1982; Delgado, 1990).  Recent analytic and          
reporting guidelines that should be used for most NHANES III analyses and       
publications are contained in Analytic and Reporting Guidelines (U.S. DHHS,     
1996).  These recommendations differ slightly from those used by analysts for   
previous NHANES surveys.  These suggested guidelines provide a framework to     
users for producing estimates that conform to the analytic design of the        
survey.  All users are strongly urged to review these analytic and reporting    
guidelines before beginning any analyses of NHANES III data.                    
                                                                                
                                                                               
It is important to remember that this set of statistical guidelines is not      
absolute.  When conducting analyses, the analyst needs to use his/her           
subject matter knowledge (including methodological issues) as well as           
information about the survey design.  The more one deviates from the original   
analytic categories defined in the sample design, the more important it is to   
evaluate the results carefully and to interpret the findings cautiously.        
                                                                                
In NHANES III, 89 survey locations were randomly divided into two sets or       
phases, the first consisting of 44 and the other of 45 locations.  One set      
of PSU's was allocated to the first three-year survey period (1988-91) and      
the other set to the second three-year period (1991-94).  Therefore, unbiased   
national estimates of health and nutrition characteristics can be               
independently produced for each phase as well as for both phases combined.      
Computation of national estimates from both phases combined (i.e., total        
NHANES III) is the preferred option; individual phase estimates may be          
highly variable.  In addition, individual phase estimates are not               
statistically independent.  It is also difficult to evaluate whether            
differences in individual phase estimates are real or due to methodological     
differences.  That is, differences may be due to changes in sampling methods    
or data collection methodology over time.  At this time, there is no valid      
statistical test for examining differences between Phase 1 and Phase 2.         
Therefore, although point estimates can be produced separately for each         
phase, no test is available to test whether those estimates are                 
significantly different from each other.                                        
                                                                                
NHANES III is based on a complex, multi-stage probability sample design.        
Several aspects of the NHANES design must be taken into account in data         
analysis, including the sample weights and the complex survey design.           
Appropriate sample weights are needed to estimate prevalence, means,            
medians, and other statistics.  Sample weights are used to produce correct      
population estimates because each sample person does not have the same          
probability of selection.  The sample weights incorporate the differential      
probabilities of selection and include adjustments for noncoverage and          
nonresponse.  A detailed discussion of nonresponse adjustments and issues       
related to survey coverage have been published (U.S. DHHS, 1996).  With the     
large oversampling of young children, older persons, black persons, and         
Mexican-Americans in NHANES III, it is essential that the sample weights be     
used in all analyses.  Otherwise, a misinterpretation of results is highly      
likely.  Other aspects of the design that must be taken into account in data    
analyses are the strata and PSU pairings from the sample design.  These         
pairings should be used to estimate variances and test for statistical          
significance.  For weighted analyses, analysts can use special computer         
software packages that use an appropriate method for estimating variances for   
complex samples such as SUDAAN (Shah, 1995) and WesVarPC (Westat, 1996).        
                                                                                
Although initial exploratory analyses may be performed on unweighted data       
using standard statistical packages and assuming simple random sampling,        
final analyses should be done on weighted data using appropriate sample         
weights.  A summary of the weighting methodology and the type of sample         
weights developed for NHANES III is included in Weighting and Estimation        
Methodology (U.S. DHHS, 1996).                                                  
                                                                                
The purpose of weighting the sample data is to permit analysts to produce       
estimates of statistics that would have been obtained if the entire             
sampling frame (the United States) had been surveyed.  Sample weights can be    
considered as measures of the number of persons the particular sample           
observation represents.  Weighting takes into account several features of       
the survey:  the specific probabilities of selection for the individual         
domains that were oversampled as well as nonresponse and differences between    
the sample and the total U.S. population.  Differences between the sample and   
                                                                                
                                                                               
the population may arise due to sampling variability, differential              
undercoverage in the survey among demographic groups, and possibly other        
types of response errors, such as differential response rates or                
misclassification errors.  Sample weighting in NHANES III was used to:          
                                                                                
1.   Compensate for differential probabilities of selection among subgroups     
     (i.e., age-sex-race-ethnicity subdomains where persons living in           
     different geographic strata were sampled at different rates);              
2.   Reduce biases arising from the fact that nonrespondents may be             
     different from those who participate;                                      
3.   Bring sample data up to the dimensions of the target population            
     totals;                                                                    
4.   Compensate, to the extent possible, for inadequacies in the sampling       
     frame (resulting from omissions of some housing units in the listing       
     of area segments, omissions of persons with no fixed address, etc.); and   
5.   To reduce variances in the estimation procedure by using auxiliary         
     information that is known with a high degree of accuracy.                  
                                                                                
In NHANES III, the sample weighting was carried out in three stages.  The       
first stage involved the computation of weights to compensate for unequal       
probabilities of selection (objective 1, above).  The second stage adjusted     
for nonresponse (objective 2).  The third stage used poststratification of      
the sample weights to Census Bureau estimates of the U.S. population to         
accomplish the third, fourth, and fifth objectives simultaneously.  In          
NHANES III, several types of sample weights (see the sample weights table       
that follows) were computed for the interviewed and examined sample and are     
included in the NHANES III data file.  Also, sample weights were computed       
separately for Phase 1 (1988-91), Phase 2 (1991-94), and total NHANES III       
(1988-94) to facilitate analysis of items collected only in Phase 1, only       
in Phase 2, and over six years of the survey.  Three sets of pseudo strata      
and PSU pairings are provided to use with SUDAAN in variance estimation.        
Since NHANES III is based on a complex, multi-stage sample design,              
appropriate sample weights should be used in analyses to produce national       
estimates of prevalence and associated variances while accounting for           
unequal probability of selection of sample persons.  For example, the final     
interview weight, WTPFQX6, should be used for analysis of the items or          
questions from the family or household questionnaires, and the final MEC        
examination weight, WTPFEX6, should be used for analysis of the                 
questionnaires and measurements administered in the MEC.  Furthermore, for a    
combined analysis of measurements from the MEC examinations and associated      
medical history questions from the household interview, the final MEC           
examination weight, WTPFEX6, should be used.  We recommend using SUDAAN         
(Shah, 1995) to estimate statistics of interest and the associated variance.    
However, one can also use other published methods for variance estimation.      
Application of SUDAAN and alternative methods, such as the average design       
effect approach, balance repeated replication (BRR) methods, or jackknife       
methods for variance estimation, are discussed in Weighting and Estimation      
Methodology (U.S. DHHS, 1996).

          Use only in conjunction with the MEC+home-examined sample and

          Use only in conjunction with the allergy subsample and with items

          Use only in conjunction with the MEC- and home-examined persons       
          assigned to the afternoon/evening subsample and with items            
          collected during the MEC and home examinations.                       
                                                                                
                                                                               
               DATA PREPARATION AND PROCESSING PROCEDURES                       
                                                                                
                                                                                
Automated data collection procedures for the survey were introduced in          
NHANES III.  In the mobile examination centers, data for the interview and      
examination components were recorded directly onto a computerized data          
collection form.  With the exception of a few independently automated           
systems, the system was centrally integrated.  This operation allowed for       
ongoing monitoring of much of the data.  Before the introduction of the         
computer-assisted personal interview (CAPI), the household questionnaire        
data were reviewed manually by field editors and interviewers.  CAPI            
(1992-1994 only) questionnaires featured built-in edits to prevent entering     
inconsistencies and out-of-range responses.  The multi-level data               
collection and quality control systems are discussed in detail in the Plan      
and Operation of the Third National Health and Nutrition Examination Survey,    
1988-1994 (NCHS, 1994; U.S. DHHS, 1996).  All interview, laboratory, and        
examination data were sent to NCHS for final processing.                        
                                                                                
Guidelines were developed that provided standards for naming variables,         
filling missing values and coding conventional responses, handling missing      
records, and standardizing two-part quantity/unit questionnaire variables.      
NCHS staff, assisted by contract staff, developed data editing                  
specifications that checked data sets for valid codes, ranges, and skip         
pattern consistencies and examined the consistency of values between            
interrelated variables.  Comments, collected in both interviews and             
examination components, were reviewed and recoded when possible.  Responses     
to "Other" and "Specify" were recoded either to existing code categories or     
to new categories.  The documentation for each data set includes notes for      
those variables that have been recoded and standardized and for those           
variables that differ significantly from what appears in the original data      
collection instrument.  While the data have undergone many quality control      
and editing procedures, there still may be values that appear extreme or        
illogical.  Values that varied considerably from what was expected were         
examined by analysts who checked for comments or other responses that might     
help to clarify unusual values.  Generally, values were retained unless they    
could not possibly be true, in which case they were changed to "Blank but       
applicable."  Therefore, the user must review each data set for extreme or      
inconsistent values and determine the status of each value for analysis.        
                                                                                
Several editing conventions were used in the creation of final analytic         
data sets:                                                                      
                                                                                
1.   Standardized variables were created to replace all two-part                
     quantity/unit questions using standard conversion factors.                 
     Standardized variables have the same name as the variable of the           
     two-part question with an "S" suffix.  For instance, MAPF18S (Months       
     received WIC benefits) in the MEC Adult Questionnaire was created from     
     the two-part response option to question F18, "How long did you receive    
     benefits from the WIC program?," using the conversion factor 12 months     
     per year.                                                                  
                                                                                
2.   Recoded variables were created by combining responses from two or more     
     like variables, or by collapsing responses to create a summary             
     variable for the purpose of confidentiality.  Recoded variables have the   
     original variable name with an R suffix.  For example, place of birth      
     variable (HFA6X) in the Family Questionnaire was collapsed to a three      
     level response category (U.S., Mexico, Other) and renamed HFA6XCR.         
     Generally, only the recoded variable has been included in the data file.   
                                                                                
                                                                               
3.   Fill values, a series of one or more digits, were used to represent        
     certain specific conditions or responses.  Below is a list of the fill     
     values that were employed.  Some of the fill values pertain only to        
     questionnaire data, although 8-fill and blank-fill values are found in     
     all data sets.  Other fill values, not included in this list, are used     
     to represent component-specific conditions.                                
                                                                                
     6-fills = Varies/varied. (Questionnaires only)                             
                                                                                
     7-fills = Fewer than the smallest number that could be reported within     
     the question structure (e.g., fewer than one cigarette per day).           
     (Questionnaires only)                                                      
                                                                                
     8-fills = Blank but applicable/cannot be determined.  This means that      
     a respondent was eligible to receive the question, test, or component      
     but did not because of refusal, lack of time, lack of staff, loss of       
     data, broken vial, language barrier, unreliability, or other similar       
     reasons.                                                                   
                                                                                
     9-fills = Don't know.  This fill was used only when a respondent did       
     not know the response to a question and said, "I don't know."              
     (Questionnaires only)                                                      
                                                                                
     Blank fills = Inapplicable.  If a respondent was not eligible for a        
     questionnaire, test, or component because of age, gender, or specific      
     reason, the variable was blank-filled.  In the questionnaire, if a         
     respondent was not asked a question because of a skip-pattern,             
     variables corresponding to the question were blank-filled.  For            
     examination or laboratory components, if a person was excluded by a        
     defined protocol (e.g., screening exclusion questions) and these           
     criteria are included in the data set, then the corresponding              
     variables were blank-filled for that person.  For home examinees,          
     variables for examination components and blood tests not performed as      
     part of the home examination protocol were blank-filled.                   
                                                                                
4.   For variables describing discrete data, codes of zero (0) were used to     
     mean "none," "never," or the equivalent.  Value labels for which "0"       
     is used include:  "has not had," "never regularly," "still taking," or     
     "never stopped using."  Unless otherwise labeled, for variables            
     containing continuous data, "zero" means "zero.                            
                                                                                
5.   Where there are logical skip patterns in the flow of the questionnaire     
     or examination component, the skip was indicated by placing the            
     variable label of the skip destination in parentheses as part of the       
     value label of the response generating the skip.  For example, in the      
     Physical Function Evaluation, the variable PFPWC (in wheelchair) has a     
     value label, "2  No (PFPSCOOT)" that means that the next item for          
     persons not in a wheelchair would be represented by the variable,          
     PFPSCOOT.                                                                  
                                                                                
                                                                                
Variable Nomenclature                                                           
                                                                                
A unique name was assigned to every NHANES III variable using a standard        
convention.  By following this naming convention, the origin of each            
variable is clear, and there is no chance of overlaying similar variables       
across multiple components.  Variables range in length from three to eight      
characters.  The first two variable characters represent the topic (e.g.,       
analyte, questionnaire instrument, examination component) and are listed        
below alphabetically by topic.  For questionnaires administered in the          
household, the remainder of the variable name following the first two           
                                                                               
characters indicates the question section and number.  For example, data        
for the response to the Household Adult Questionnaire question B1 are           
contained in the variable HAB1.  For most laboratory and examination            
variables, as well as some other variables, a "P" in the third position         
refers to "primary" and the remainder of the variable name is a brief           
description of the item.  For instance, in the Laboratory Data File,            
information on the length of time the person fasted before the first blood      
draw is contained in the variable PHPFAST.  The variable PHPFAST was derived    
as follows:  characters 1-2 (PH) refer to "phlebotomy," character 3 (P)         
refers to "primary," characters 4-8 (FAST) refer to an abbreviation for         
"fasting."

The NHANES III Household Youth Questionnaire Data File contains all data        
collected during the household interviews for children and youths 2 months to 16
years of age.  Demographic data, survey design variables, and sampling weights  
for this age group are also included.  This first section provides a brief      
background and information about the contents of the Household Youth            
Questionnaire Data File.  The second section is the Data File Index, a          
listing of all of the variables with the standard names and their positions in  
the data set.  The third section contains the frequency counts and codes for    
all of the variables, followed by notes and appendices.  References are found   
in the fourth section.                                                          
                                                                                
                                                                                
The data that comprise this file were obtained from three separate interviews   
administered in the household: the Screener, the Family, and Household Youth    
questionnaires.  The Screener was a brief interview administered to all         
households within selected sampling units to determine eligibility for          
participation in the survey.  Information obtained from the Screener            
questionnaire was the basis for the demographic variables, and survey-related   
variables.  The purpose of the Family questionnaire was to obtain data on       
educational levels, occupation, health insurance coverage, income, and food     
security of family members, and to record characteristics of the house itself.  
The Household Youth questionnaire was administered to a proxy respondent,       
usually the child's parent or guardian.  Questions on topics such as birth      
experience, motor and social development, health services usage, dental care,   
selected medical conditions, school attendance, language, and vitamin, mineral  
and medicine usage were asked according to age subgroups.  The Household        
Youth questionnaire was completed for 13,944 children and youths ages 2 months -
16 years of age during the six years of NHANES III.                             
                                                                                
Interviews were conducted by field staff, in both English and Spanish.  All     
staff received intensive initial training, and formal retraining was conducted  
throughout the survey to ensure that high skill levels were maintained.  The    
data collection system was automated in Phase 2, at which time interviews were  
conducted using CAPI (computer-assisted personal interview).  Details on survey 
instruments and forms, training manuals and data collection procedures are      
published elsewhere (U.S. DHHS, 1996).                                          
                                                                                
Data processing and editing were performed for consistency of responses within  
sections of the questionnaire sections. Identifiable information including      
names, addresses, and social security numbers, as well as other administrative  
items were excluded from the data file in order to ensure confidentiality. Notes
are provided both for standardized and recoded variables, and for variables     
requiring additional explanation.  Hand cards and other diagrams that were used 
during interviews are located with copies of the survey instruments in the Plan 
and Operation of the Third National Health and Nutrition Examination Survey     
(U.S. DHHS, 1996).  Users should note that because questions were modified,     
reordered, added, or deleted, this documentation may not follow the             
exact ordering of the questions on survey instruments.                          
                                                                                
Since NHANES III was based on a complex multistage design, appropriate sample   
weights should be used in analyses to produce national estimates and associated 
variances.  The final interview weights WTPFQX6 should be used for analysis of  
interview data alone.  If interview data are combined with examination,         
laboratory or dietary data, the total MEC weights (WTPFEX6) or MEC+home weights 
(WTPFHX6) should be used.

     This variable identifies the interview or examination status of all persons
     selected for the NHANES III sample.  Interviewed persons completed         
     preselected questions in specific sections of the Household Adult or Youth 
     Questionnaires.  Mobile examination center (MEC)-examined persons were     
     interviewed and successfully completed at least one examination component  
     in the MEC. Home-examined persons were interviewed and successfully        
     completed at least one home examination component.  The home examination   
     was an option for frail older adults, infants 2-11 months of age, and other
     adults who were unable to come to the MEC.

     This key analytic variable, based on the NHANES III survey design, was     
     derived from many sources of data and is based on reported race and        
     ethnicity.  The other category includes all Hispanics, regardless of       
     race, who were not Mexican-American and also includes all non-Hispanics    
     from racial groups other than white or black.                              
                                                                                
                                                                                
DMARACER:  Race                                                                 
                                                                                
     This variable was obtained from two primary sources: the Screener and      
     the Family Questionnaires.  Prior to the selection of the sample, race     
     (Black, White, Other) was self-reported or reported by proxy in the        
     Screener Questionnaire.  During the administration of the Family           
     Questionnaire, race was self-reported or reported by the respondent of     
     the Family Questionnaire from five categories (Aleut, Eskimo, American     
     Indian, Asian or Pacific Islander, Black, White, Other).  Responses from   
     the two sources were adjudicated, as necessary, to create a three level    
     variable (Black, White, Other).                                            
                                                                                
                                                                                
DMAETHNR:  Ethnicity                                                            
                                                                                
     This variable was obtained from two primary sources: the Screener and      
     the Family Questionnaires.  As part of both interviews, hand cards were    
     used to determine Mexican/Mexican-American or Other Latin                  
     American/Spanish ancestry or national origin.  Responses of non-Hispanic   
     ancestry or national origin were categorized as other.  Responses from     
     the two interviews were adjudicated, as necessary, and this three          
     level variable was created.                                                
                                                                                
                                                                                
HSAGEIR:  Age (Screener Questionnaire)                                          
                                                                                
     Age was calculated using the birth date which was obtained from the        
     Screener Questionnaire.  The variable HSAGEU provides the age unit         
     (months or years) for HSAGEIR.  Ages of 90 years or greater were recoded   
     into a single category of 90+ years to help protect the confidentiality    
     of survey participants.                                                    
                                                                                
                                                                               
HSAITMOR:  Age in months (Screener Questionnaire)                               
                                                                                
     Age in months was calculated by computing number of months between the     
     Screener Questionnaire date and date of birth.  This variable was          
     created for analyses where exact age at the interview may be needed.       
     HSAITMOR differs slightly from the age in years (HSAGEIR), the variable    
     most often used for analyses.  Ages of 1080 months and older (90 years     
     and older) were recoded into a single category of 1080+ months to          
     protect the confidentiality of survey participants.                        
                                                                                
                                                                                
HSFSIZER:  Family Size                                                          
                                                                                
     Family size represents the total number of related persons living in a     
     household (single dwelling unit).  All household members were rostered     
     by family during the Screener interview.  Household members who were       
     related to the family reference person (knowledgeable household member     
     17 years or older who owned or rented the dwelling unit) by blood or       
     marriage were considered part of the family.  Adopted children, foster-    
     and god-children were also included, if they were living in the dwelling   
     unit.  However, family members who were away at college, or living

     unrelated to the reference person were considered members of separate      
     families.  Families with 10 members or more were recoded into a single     
     response category of 10+ persons to help protect confidentiality.  See

     Household size represents the total number of persons living in a single   
     dwelling unit, both related and unrelated.  All permanent household        
     members were rostered according to their family as part the Screener       
     interview.  This was done in order to obtain a complete list of all        
     persons living or staying in the dwelling unit, and to distinguish         
     household and family members.  Households with 10 members or more were     
     recoded into a single response category of 10+ persons to help protect     
     confidentiality.  See note for Family Size (HFHSIZER).

     These county FIPS codes identify large counties with populations of        
     500,000 and more that were sampled in the survey.  Counties with           
     population less than 500,000 are not included to prevent identification    
     of these locations.  See Appendix 1 for listing of codes.

DMPMETRO:  Urbanization classification based on USDA Rural-Urban                
               continuum codes                                                  
                                                                                
     These classifications are based on the USDA Rural-Urban codes (Butler and  
     Beale, 1993) that describe metro and nonmetro counties by degree of        
     urbanization and nearness to metro areas.  The USDA codes were recoded     
     into two categories to prevent identification of counties that were        
     sampled in the survey.

     The United States was divided into four broad geographic regions as        
     defined by the Bureau of Census.  Because all states were not included in  
     the selected sample, regional estimates may not be representative for a    
     given region.                                                              
                                                                                
                                                                                
DMPPIR:  Poverty income ratio (or poverty index)                                
                                                                                
     The poverty income ratio (PIR) was computed as a ratio of two              
     components.  The numerator was the midpoint of the observed family         
     income category in the Family Questionnaire variable:HFF19R.  The          
     denominator was the poverty threshold, the age of the family reference     
     person, and the calender year in which the family was interviewed.         
                                                                                
     Poverty threshold values (in dollars) are produced annually by the         
     Census Bureau (Series P-60).  These threshold values are based on          
     calendar years and adjusted for changes caused by inflation between        
     calendar years.  Reports for each of the calendar years in the survey      
     (1988-94) were used in the calculation of PIR.  For the years 1991 and     
     1994, data from preliminary reports were used.  The poverty income ratio   
     allows income data to be analyzed in a comparable manner across the six    
     years of the survey and with previous NHANES.                              
                                                                                
     Persons who reported having had no income and were assigned a zero value   
     for PIR.  A substantial proportion of persons refused to report their      
     income or income category during the Family Questionnaire.  Due to the     
     income nonresponse the potential for bias in PIR may be high.  Users are   
     cautioned to examine potential nonresponse bias for PIR and                
     other income variables.

     For operational purposes, 81 primary sampling units were divided into 89   
     survey locations (or stands) and randomly allocated to two three-year      
     phases.  Phase 1 data were collected from October 1988 through October     
     1991 and Phase 2 data were collected from October 1991 through October     
     1994.                                                                      
                                                                                
                                                                                
SDPSTRA6, SDPSTRA1, SDPSTRA2, and SDPPSU6, SDPPSU1, SDPPSU2: Pseudo strata      
               codes and pseudo PSU pair codes                                  
                                                                                
     Because NHANES III was based upon a complex sample design, the             
     assumptions of many statistical tests and routinely available              
     statistical programs are not met.  For this reason, when estimates of      
     the variances of statistics are computed, the technique of estimation      
     must be based upon complex sampling theory.  In order to provide users     
     with the capability of estimating the complex sample variances, 49         
     pseudo strata and a pair of Primary Sampling Unit (PSU) codes per          
     stratum were designed.                                                     
                                                                                
     A software package, "SUDAAN- Software for the Statistical Analysis of      
     Correlated Data" (Shah, 1995), was developed by the Research Triangle      
     Institute to analyze complex sample design data like NHANES.  SUDAAN       
     uses strata and PSU codes to conduct analysis with two PSU per stratum     
     design.  Therefore, definition of pseudo strata and PSU provided in this   
     data file should be used to compute complex sample variances in            
     analyses.  Other software available for estimation of complex sample       
     variance may also be used.  For further discussion of methods of           
     variance estimation in NHANES III, see additional information on this      
     subject in Weighting and Estimation Methodology (U.S. DHHS, 1996) and

     These MEC sampling weights should be used for analysis of measurements     
     or interview items collected in the MEC.  Persons who were not examined    
     in the MEC have a sampling weight of zero and should be excluded from      
     analyses.  To compute final MEC examination weights, final interview       
     weights were first adjusted for nonresponse to MEC examinations, then

     These MEC+home sampling weights should be used for analysis of the         
     examination items where measurements or interview items were collected     
     in the MEC and home.  Persons who were not examined in the MEC or home     
     have a sampling weight of zero and should be excluded from analyses.  To   
     compute final MEC+home examination weights, final interview weights were   
     first adjusted for nonresponse to MEC and home examinations, then

     These subsample weights are for analysis of allergy measurements.          
     Allergy skin reactivity tests were administered to all MEC-examined        
     persons aged 6-19 years and a random half-sample of the adults aged        
     20-59 years.  Eligible MEC-examined persons who did not complete the       
     allergy tests have a sampling weight of zero and should be excluded from   
     the analyses.  Final MEC examination weights were first adjusted for       
     selection of the half-sample among adults (20-59 years), and               
     post-stratified to the unpublished Current Population Survey 1990 (Phase

     These subsample weights are for analysis of measurements from the          
     Central Nervous System (CNS) test.  The CNS examination was administered   
     to a random half-sample of the adults aged 20-69 years.  Eligible          
     MEC-examined persons who did not complete CNS testing have a sampling      
     weight of zero and should be excluded from the analyses.  Final MEC        
     examination weights were first adjusted for selection of half sample       
     among adults (20-59 years), and post-stratified to unpublished Current

     and older who were scheduled and examined in the MEC morning session.      
     Sampled households in the survey were randomly assigned to one of two      
     groups -- morning session ("standard") or afternoon/evening session        
     ("modified") assignments.  All sample persons from a household received    
     the same session assignment and were requested to schedule examinations    
     for the assigned session.  Fasting instructions varied by age and          
     session assignment (Plan and Operation of The Third National Health and    
     Nutrition Examination Survey, 1988-94 , U.S. DHHS, 1996).  It should be    
     noted that actual fasting time may have differed from the instructed       
     fasting time and can be obtained from the variable PHPFAST in the NHANES   
     III Laboratory Data  File.  To compute these weights, final MEC examination

     half samples and adjust sampling weights in each of the random half        
     samples.  Sampling weights in one half sample were multiplied by the       
     factor k=1.7 and in the other half sample by k=0.3 using the Fay's         
     method.  After this adjustment, sampling weights were further adjusted     
     for non-response and post-stratified using the same procedure as the       
     final full sample interview weights.  These weights should be used only    
     for estimating variance of items from the household adult and youth        
     interviews.  For details, see Weighting and Estimation Methodology

     This variables designates the language of conduct for the MEC examination. 
     questionnaires were designed to be implemented in a bilingual              
     (English/Spanish) format so that respondents could to be interviewed in    
     their preferred language.  When it was necessary to conduct an interview   
     in a another language, a translator assisted the interviewer in            
     administering the questionnaires.  These interviews were coded as other.

     This variable designates the period during the day that the examination    
     occurred.  To increase response rates and allow flexibility, examinations  
     were scheduled in three sessions:  morning, afternoon and evening.  On     
     occasion, more than one session was attended in order to complete the full 
     examination. In such a situation, the session was coded as the one when    
     most of the examinations were completed.

     Age in total months was created for special analyses where exact age at the
     examination may be needed (e.g., computation of growth charts).  It was    
     calculated by computing number of months between examination date and the  
     date of birth.  Some examinees may have had a birthday between household   
     interview and examination so that this computed age at examination may     
     differ slightly from the age reported in HSAGEIR (and HSAGEU), or HSAITMOR.
     For most analyses age reported in HSAGEIR (and HSAGEU) should be used.     
     Ages of 1080 months and older (90 years and older) were recoded into a     
     single category of 1080+ months to protect the confidentiality of survey   
     participants.

     This variable designates the period during the day that the examination    
     occurred.  To increase response rates and allow flexibility, examinations  
     were scheduled in three sessions:  morning, afternoon and evening.  On     
     occasion, more than one session was attended in order to complete the full 
     examination. In such a situation, the session was coded as the one when    
     most of the examinations were completed.

HFVERS:  Version of household family questionnaire                              
                                                                                
     During the six years of the survey, portions of the Family Questionnaire   
     were modified several times resulting in four different versions.          
     Questions were dropped, revised, or added to meet divergent research needs.
     Changes were made in the ordering of selected questions, in the reference  
     time period, and in the wording of questions.  Versions 1                  
     and 2 were implemented during Phase 1, and Versions 3 and 4 were           
     implemented during Phase 2.  Versions 3 and 4 vary only by implementation  
     mode; Version 3 was conducted by pencil and paper and Version 4 was        
     conducted using the computer-assisted personal interview (CAPI).  The      
     Family Questionnaire printed in the Plan and Operation of the Third        
     National Health and Nutrition Examination Survey (U.S. DHHS, 1996) most    
     closely resembles the final version. During the editing of this data       
     file, variables from different versions were put together where            
     feasible to enable analysis of complete six-year data for as               
     many variables as possible.  Notes elaborating question modifications      
     are provided in this document.  Users should carefully examine the         
     differences to determine how to conduct analyses.  HFVERS can be used      
     to identify the sample persons who were administered each version.         
                                                                                
                                                                                
HFLANG:  Language of household family questionnaire                             
                                                                                
     This variable designates the language of conduct for the Family            
     Questionnaire.  Questionnaires were designed to be implemented in a        
     bilingual (English/Spanish) format so that respondents could to be         
     interviewed in their preferred language.  When it was necessary to conduct 
     an interview in another language, a translator assisted the interviewer in 
     administering the questionnaires.  These interviews were coded as "Other". 
                                                                                
                                                                                
                                                                                
Individual Characteristics                                                      
                                                                                
HFA6XCR:  In what state or foreign country was -- born?                         
                                                                                
     This recoded variable derived from question A6 in the Household Family     
     Questionnaire.  Place of birth was regrouped into three broad categories in
     order to maintain confidentiality of the survey participant.               
                                                                                
                                                                                
HFA8R:  What is the highest grade or year of regular school -- has completed?   
                                                                                
     This recoded variable was created from two separate questions A7 and A8.   
     Question A7 asked "What is the highest grade/year of regular school -- has 
     ever attended?"  Question A8 asked "Did you finish that grade/year?"       
                                                                                
                                                                               
HFB1-HFB17:  Health insurance coverage questions                                
                                                                                
     Three versions of the health insurance questions were asked during the     
     survey.  The major difference was the time frame referenced for recall     
     (e.g. "now" versus "in the last month").  Some questions had slight        
     variations in the wording across versions; others may have been omitted    
     from one version but added in another.  When differences in versions were  
     slight, the variable was created for the full survey time period.  When    
     differences were significant, version-specific variables were maintained.  
     The variable HFVERS can be used to identify version.  Separate notes are   
     provided to show differences by version. Because of many changes for this  
     section of questions, data may not be available for all survey participants

     This question differed in the time frame referenced for recall.  Versions 1
     and 2 read, "Is anyone in the family NOW covered by Medicare?"  Versions 3 
     and 4 read "DURING THE LAST MONTH was anyone in the family covered by      
     Medicare?"

               persons in the family                                            
                                                                                
     This question was not asked on Version 1, and had time frame variations    
     between Versions 2 and 3 and 4.  Version 2 reads, "DURING THE PAST 12      
     MONTHS was -- covered by CHAMPUS/CHAMPVA, the VA or military health care?" 
     Version 3 and 4 read, "DURING THE LAST MONTH was -- covered by             
     CHAMPUS/CHAMPVA, the VA or military health care?"

     This question changed in wording, and in time frame between all versions   
     versions of the questionnaire.  For Versions 1 and 2, the frame of         
     reference was NOW.  For Versions 3 and 4, the frame of reference was DURING
                                                                                
     THE LAST MONTH. For Versions 1 and 3 and 4 the introductory statement read,
     "We are interested in all kinds of health insurance plans except those that
     pay only for accidents."  The Version 2 introductory statement read, "We   
     are interested in all kinds of private health insurance except those that  
     pay only for accidents."                                                   
                                                                                
     Version 1 of the question read, "(Not counting Medicare) is anyone in the  
     family NOW covered by a health insurance plan that pays any part of a      
     hospital, doctor's, or surgeon's bill?"  Version 2 of the question reads,  
     "(Not counting Medicare, Medicaid, or Veteran's payments) is anyone in the 
     family NOW covered by a health insurance plan obtained privately or through
     a current or former employer or union that pays any part of a hospital,    
     doctor's, or surgeon's bill?"  Versions 3 and 4 of the question read, "(Not
     counting Medicare, Medicaid, or Veteran's payments) DURING THE LAST MONTH  
     was anyone in the family covered by a health insurance plan obtained       
     privately or through a current or former employer or union that pays any   
     part of a hospital stay or routine doctor's care?   Include membership in a
     health maintenance organization."                                          
                                                                                
                                                                               
HFB11 and HFB11A-HFB11E:  Coverage by health insurance plans obtained privately 
               or through an employer or union for specific family members      
                                                                                
     Questions HFB11A-HFB11E follow from the lead-in question HFB11.  The time  
     frame for all of the questions is dependent upon the version of the lead-in
     question.  Version 1 read, "Is -- NOW covered by a health insurance plan?" 
     Version 2 read,"Is -- covered by a health insurance plan?"  Versions 3 and 
     4 read, "During the LAST MONTH was -- covered by a health insurance plan   
     obtained privately or through an employer or union?"  Many of the questions
     that follow are version-specific, as noted.

     This question was asked only on Versions 3 and 4 of the questionnaire.

               through an employer or union                                     
                                                                                
     This question was not asked in Version 1 of the questionnaire.

               insurance coverage                                               
                                                                                
     This question was asked only on Versions 3 and 4 of the questionnaire.     
                                                                                
                                                                                
HFB14AA-HFB14BI:  Reasons for not having health insurance                       
                                                                                
     The response categories for this question differed significantly by        
     version and were therefore all included.  A respondent could give multiple 
     responses for this question.  HFB14AA and HFB14AH were possible responses  
     in Version 1. HFB14BA-HFB14BI were possible responses in Version 2.        
                                                                                
                                                                                
HFB16A and HFB16B:  Main reason -- not covered by health insurance              
                                                                                
     These were retained as separate variables because the response categories  
     for the question differed significantly by Version. Categories for question
     16A were included in Versions 1 and 2.  Categories for question 16B were   
     included in Versions 3 and 4.                                              
                                                                                
                                                                               
HFB17:  Health insurance that pays any part of dental care                      
                                                                                
     This was asked only on Version 1 of the questionnaire.  The question for   
     variable HFB11C (Versions 2,3 and 4) also dealt with dental care coverage, 
     though had different criteria in its lead-in question.

     This variable was created from question C2 to standardize responses to     
     pounds.  For responses in kilograms the conversion factor 2.2046           
     kilograms/pound.

     This variable was created from question C3 to standardize responses to     
     inches.  For responses in centimeters, the conversion factor was 0.3937    
     centimeters/inch.                                                          
                                                                                
                                                                                
HFC4S:  How much (does --'s father/do you) weigh? (pounds)                      
                                                                                
     This variable was created from question C4 to standardize responses to     
     pounds.  For responses in kilograms the conversion factor 2.2046           
     kilograms/pound.                                                           
                                                                                
                                                                                
HFC5S:  How tall (is --'s father/are you)? (inches)                             
                                                                                
     This variable was created from question C3 to standardize responses to     
     inches.  For responses in centimeters, the conversion factor was 0.3937    
     centimeters/inch.                                                          
                                                                                
                                                                                
HFC7S:  How long has -- lived at this address? (weeks)                          
                                                                                
     This standardized variable was created from the two-part question (quantity
     and unit) C7 using the conversion factors 4.3 weeks/month and 52           
     weeks/year.  If the response was "whole life", then the time was converted 
     to weeks based on age at interview (HSAGEIR and HSAGEU).

     This variable was created from the two part question (quantity and unit) C8
     using the conversion factors 4.3 weeks/month and 52 weeks/year.  If the    
     response was "whole life", then the time was converted to weeks based on   
     age at interview (HSAGEIR and HSAGEU).

     These questions were asked about the occupation of FRPs only if they were  
     not sample persons.  FRPs who were also sample persons responded to

HFD10R:  Occupation of Family Reference Person                                  
                                                                                
     Classification of occupation based on categories defined by the U.S. Bureau
     of Census in 1980 (U.S. Bureau of the Census, 1981).                       
                                                                                
                                                                                
HFD12:  Class of worker Family Reference Person (FRP)                           
                                                                                
     The category armed forces was added in Versions 3 and 4.  In the earlier   
     version, armed force status can be ascertained from HFD9.  In Versions 3   
     and 4,FRPs who were in active military service skipped out of the detailed 
     occupational questions in this section.                                    
                                                                                
                                                                                
HFE1:  Year house was built                                                     
                                                                                
     A small number of sample persons were unable to answer this question       
     because they reported living in mobile homes.  Since there was not category
     for this response, they were included as blank but applicable.             
                                                                                
HFF2R:  Total number of persons who smoke cigarettes in the home                
                                                                                
     This total was derived by counting the number of persons recorded          
     as smoking in the home (questions F1 and F2).                              
                                                                                
HFF4-HFF8:  Food Insufficiency                                                  
                                                                                
     The intent of these questions was to capture insufficient food availability
                                                                                
     at the family level due to lack of money and/or other resources as answered
     by the respondent to the Family Questionnaire. Related questions answered  
     by individuals or their proxies were asked following the 24-hour dietary   
     recall in the MEC (See NHANES III Dietary Data File).                      
                                                                                
                                                                                
HFF6:  Reasons for no food or money to buy food                                 
                                                                                
     More than one response could be answered yes for question F6.  Textual     
     responses to this question were reviewed and coded into existing categories
     HFF6A-HFF6C where possible.  Remaining responses which could not be coded  
     back into existing questions, such as health reasons, are included in HFF6D
     as "Other."                                                                
                                                                                
                                                                                
HFF7 and HFF8:  Size of meals cut                                               
                                                                                
     Questions F7 and F8 were asked only in Versions 3 and 4. The variable      
     HFVERS can be used to select only those records for sample persons who were
     asked these questions.  The purpose of the questions was to ascertain      
     information on cutting back or skipping meals as a coping strategy for not 
     having enough food in the family.                                          
                                                                                
                                                                               
HFF9:  WIC participation in family                                              
                                                                                
     WIC is the Special Supplemental Food Program for Women, Infants, and       
     Children administered by the U.S. Department of Agriculture.  Question F9  
     was asked also of individuals or their proxies during the interviews that  
     took place in the MEC and home examinations. (See NHANES III Examination   
     Data File)                                                                 
                                                                                
                                                                                
HFF10 and HFF11:  Food Stamp Program participation in family                    
                                                                                
     Food stamps refers to the Food Stamp Program administered by the U.S.      
     Department of Agriculture.                                                 
                                                                                
                                                                                
HFF12A-HFF17B:  Types of family income                                          
                                                                                
     Questions F12 through F17 were structured similarly.  The first part of the
     question asked whether any family member received a certain type of income.
                                                                                
     The second part of the question indicated the recording of the line        
     number(s) for the person(s) who received the income.  Because the line     
     number from the Household Screener Composition Table will not be released, 
     the second part of the question will contain only the response for the     
     specific sample person to which a record refers.                           
                                                                                
                                                                                
HFF13A:  Social Security or Railroad Retirement payments in family              
                                                                                
     The time frame as well as the wording changed in this question.  In        
     Versions 1 and 2, the frame of reference was THE PAST 12 MONTHS.  In       
     Versions 3 and 4, the frame of reference was the LAST MONTH. Versions 1 and
     2 read "DURING THE PAST 12 MONTHS did any member of the family receive any 
     Social Security payments?"  Version 3 and 4 read "DURING THE LAST MONTH did
     anyone in the family  receive any Social Security or Railroad Retirement   
     payments?"                                                                 
                                                                                
                                                                                
HFF13DA-HFF13DB:  Reason for receiving Social Security or Railroad Retirement   
     payments                                                                   
                                                                                
     The response categories for question F13d changed significantly between    
     Versions 1 and 2 and Versions 3 and 4 so that the question was retained by 
     version.

     In Versions 1 and 2, respondents were asked to state another reason that   
     they were receiving Social Security.

     The time frame changed in this question.  In Versions 1 and 2, the frame of
     reference was THE PAST 12 MONTHS.  In Versions 3 and 4, the frame of       
     reference was the LAST MONTH.  Versions 1 and 2 read "DURING THE PAST 12   
     MONTHS did anyone in the family receive SSI (Supplemental Security Income) 
     payments from the U.S./Federal government?"  Version 3 and 4 read "DURING  
     THE LAST MONTH did anyone in the family  receive SSI (Supplemental Security
     Income) payments from the Federal government?"

     Version 3 and 4 reads "DURING THE LAST MONTH, did -- receive SSI payments  
     from the Federal government?"

     Question F14d was asked only in Versions 1 and 2 of the questionnaire.  The
     variable HFVERS should be used to select only those records for sample     
     persons who were asked this question.

     Questions F16d and F16e were asked only in Versions 2 and 3 of the         
     questionnaire.  The time frame was modified between the last two versions. 
     For question F16d, Version 2 read "Does anyone in the family NOW receive   
     assistance through the "Aid to Families with Dependent Children" Program,  
     sometimes called "AFDC" or "ADC"?"  Version 3 and 4 read "DURING THE LAST  
     MONTH did anyone in the family receive "Aid to Families with Dependent     
     Children", sometimes called AFDC or ADC?"  For question F16e, Version 2    
     read "Is -- included in the AFDC assistance payment?"  Version 3 and 4 read
     "DURING THE LAST MONTH, did -- receive "Aid to Families with Dependent     
     Children," sometimes called AFDC or ADC?"

     These questions were asked only in Version 3.  The variable HFVERS should  
     be used to select only those records for sample persons who were asked     
     these questions.

     Variable HFF19R is a recoded variable based on response categories for     
     Versions 1 and 2.  For comparability, responses to categories over $50,000 
     in Versions 3 and 4 were collapsed back into the single category "$50,000

     Respondents were allowed to indicate that their family income during the   
     last month was the annual income reported in question F19 divided by 12.   
     For these responses, the monthly income was imputed by dividing the        
     midpoint of the range selected in question F19 by 12.                      
     The response categories were changed between Versions 1 and 2 d Version 3  
     of the questionnaire.  In Versions 1 and 2, the response categories for    
     question F20 ended with the category "4,000 and over" (coded 20)  In       
     Version 3 and 4, the categories were expanded to include:

HFHSEQN:  Sequence number for Family Reference Person (FRP)                     
                                                                                
     This variable is the unique identifier for the family reference person     
     (FRP).  The FRP was designated during the Screener interview as the person 
     17 years of age or older who owned or rented the dwelling unit.  If no one 
     owned or rented the unit, then the family reference was the first family   
     member mentioned by the Screener respondent who was 17 years of age. The   
     FRP was established in order to arrange household members into family      
     units.  In earlier NHANES and in parts of the NHANES III interview         
     questionnaires, the FRP was referred to as "the head of the household."    
     (For more details, see the chapter on "Administering the Interview" in the 
     NHANES III Interviewer's Manual, U.S DHHS, 1996.)                          
                                                                                
                                                                                
HFHAGER:  Age of the Family Reference Person (FRP)                              
                                                                                
     Question A3 of the Family questionnaire asked the age (transcribed from the
     Screener) of the FRP and of each sample person. See HSAGEIR and HSAGEU for 
     the age at interview (Screener Interview) of sample persons.

     Question A4 of the Family questionnaire asked the sex of the FRP and of    
     each sample person.  See HSSEX for the sex of sample persons.

     This recoded variable was derived from question A6 in the Household Family 
     Questionnaire.  Place of birth was regrouped into three broad categories in
     order to maintain confidentiality of the survey participant.  See HFA6XCR

     This recoded variable was created from two separate questions A7 and A8 in 
     the Family questionnaire.  These questions were asked of all sample persons
     as well as of the FRP. Question A7 asked "What is the highest grade/year of
     regular school -- has ever attended?"  Question A8 asked "Did you finish   
     that grade/year?"  Persons who did not complete the grade answered in A7,  
     were coded to having completed one previous grade.  See HFA8R for completed
     years of education for sample persons.

     This derived variable combines responses from questions D2 and D3 of the   
     Family questionnaire for FRPs who were not sample persons, and from        
     questions S1 and S2 of the Household Adult questionnaire for FRPs who were 
     also sample persons.  For more detail on the occupation of the FRP see:

     Question A13 of the Family questionnaire asked whether the FRP or the      
     sample person ever served in the Armed Forces.  Persons who were serving in
     the military at the time of the interview, but living at home, were        
     permitted to be only Family Reference Persons, not sample persons.  See    
     HFA13 for the military service of sample persons.

     This variable was created from the original question A7 using the          
     conversion factor 28.349 grams/ounce (0.03527 ounces/gram) and 16          
     ounces/pound (0.00220 pounds/kilogram).                                    
                                                                                
                                                                                
HYA9R:  Approximate weight at birth                                             
                                                                                
     This variable is created by combining responses to questions HYA7S, HYA8   
     and HYA9.  The exact birth weights reported in HYA7S were categorized into 
     the 3 categories: less than 2500 grams, 2500 grams through 4100 grams, and 
     more than 4100 grams.  The responses to HYA8 and HYA9 were used when the   
     respondent did not know the exact birth weight.  If the response in A8 was 
     less than 2500 grams it was coded as 1 in HYA9R.  If the response was more 
     than 2500 grams in A8 and less than 4100 grams in A9, then it was coded as 
     2 in HYA9R.  If the response was more than 2500 grams in A8 and more than  
     4100 grams in A9 then it was coded as 3 in HYA9R.                          
                                                                                
                                                                                
HYB3S:  First fed something other than breastmilk or water                      
                                                                                
     This question was only asked in Phase 2 of the survey.  It is important to 
     note that although the skip pattern for HYB2 indicates that all persons who
     answered "yes" were then asked HYB3S, this is only true for persons        
     interviewed in Phase 2.  The variable was created from the two part        
     question (number and unit) B3 using the conversion factors 7 days/week     
     and 30.4 days/month.

HYK1A:  Has -- taken any vitamins or minerals in the past month?                
                                                                                
     This was the lead-in question for a series of questions on vitamins and    
     minerals.  If the response to this question was yes, the respondent or     
     proxy was asked the number of supplements they took.  For each supplement  
     taken the respondent was asked about how often the supplement was taken,   
     the dosage, and duration of use. The user should be aware, however, that   
     there were respondents who reported taking supplements, but did not answer 
     some or all of the remaining questions about the supplements.  Although    
     this lead-in question was designed to determine whether the respondent was 
     using any vitamin or mineral supplements, respondents often reported taking
     other types of dietary supplements such as formula diets, sports drinks,   
     herbs, plants and similar products, amino acids, bee pollen, lipotropics,  
     fish oils, and enzymes.  This information was retained along with the      
     vitamin/mineral supplements.  However, since the question did not ask      
     specifically about the use of other nonvitamin/nonmineral dietary          
     supplements, the frequency with which these products were reported should  
     not be considered to be nationally representative.  It should also be noted
     that all of the information from the section does not appear in this data  
     file; additional variables including supplement formulations will be       
     released as a separate data file.                                          
                                                                                
                                                                               
HYK1B:  Has -- taken or used any prescription medicines in the past month?      
                                                                                
     This was the lead-in question for a series of questions on prescription    
     medicines.  If the response to this question was yes, the respondent or    
     proxy was asked the number of prescription medicines they took.  For each  
     prescription medicine taken the respondent was asked to describe the health
     problem for which they took the medicine, and how long they had been taking
     the medicine.  The user should be aware, however, that there were          
     respondents who reported taking prescription medicines, but were only able 
     to answer some of the remaining prescription drug questions.  Prescribed   
     vitamin or mineral supplements (e.g., fluoride, iron, and prenatal         
     vitamins) originally reported as prescription drugs were moved to the      
     vitamin/mineral section. These could, in fact, be considered either a drug 
     or a supplement such as calcium-based antacid, calcitrol, and potassium.   
     It should also be noted that all of the information from the section does  
     not appear in this data file; additional variables including drug          
     formulations will be released as a separate data file.                     
                                                                                
                                                                                
HYK2A:  Number of vitamins/mineral supplements reported                         
                                                                                
     This variable represents the total number of different supplements reported
     by the respondent or proxy.  For each supplement reported, the interviewer 
     asked to see the supplement container in order to record the name of the   
     product and the manufacturer.  If the container was not available, the     
     interviewer probed for this information.  Supplements that appear to be    
     identical or duplications of another reported product are usually different
     forms (e.g., tablet vs. liquid) of the same product.

     This variable represents the total number of different prescription        
     medicines reported by the respondent or proxy.  For each medication        
     reported, the interviewer asked to see the medication container in order to
     record the name of the product.  If the container was not available, the   
     interviewer probed for this information.  Reports of non-prescription drug 
     use, such as antacids, were deleted.  However, calcium-containing antacids 
     were moved to the vitamin/mineral supplements section.  Medicines  that    
     appear to be identical or duplications of another reported product are     
     usually different forms (e.g., tablet vs. liquid) of the same product.

     A certainty index was derived as a means of evaluating how closely the     
     reported name of a dietary supplement matched a standard or brand name     
     product which, in turn, was used for determining nutrient intakes.  Each   
     reported dietary supplement was assigned a certainty code. The index       
     consists of six levels ranging from the highest degree of certainty that   
     the reported supplement was correctly identified (code=1) to no level the  
     lowest degree of certainty (code=6) , i.e., no match could be made between 
     the reported supplement and a standard supplement.  More specifically, the 
     code of 1 was used when the respondent provided enough information about   
     the product that it exactly matched a specific brand name supplement.  A   
     code of 2 was applied when the product name was partially incomplete or    
     misspelled, but generally identifiable.  A code of 3 was used for cases    
     where a single nutrient supplement, such as calcium, was reported without  
     the concentration.  A code of 4 was applied when a generic type of         
     supplement was reported such as "children's chewable multivitamins" or     
     "iron vitamins" when it was not possible to identify the specific brand    
     name or nutrient composition.  A code of 5 was assigned to supplements that
     could not be readily identified although they were thought to be dietary   
     supplements such as "Shaklee vitamins" or "Diamite nutritional".  A code of
     6 was used for products that could not be identified.

     Each reported dietary supplement was categorized into one of 7 broad       
     product-type classes according to general nutrient composition.  The first 
     five classes (1-5) were assigned only to vitamin and/or mineral            
     supplements.  The remaining two classes (6 and 7) were assigned to other   
     dietary supplements including amino acids, lipotropics, herbs, plants and  
     other nontraditional dietary supplements.  Dietary supplements that also   
     contained a vitamin and/or a mineral (e.g., ginseng and bee pollen with    
     vitamin E) were assigned to class 6, whereas those that did not include    
     vitamins or minerals were assigned to class 7.

     These variables were created for each reported dietary supplement from the 
     two-part (number and unit) question K6, and indicate how frequently each   
     supplement was taken in the past month.  The conversion factors used for   
     days and weeks were 30 and 4, respectively.  While frequency of use was    
     standardized to "month," new supplement users may have been taking the     
     supplement for less a month at the time of the interview.  Analysts,       
     therefore, may want to examine duration (HYK8S variables) as well as       
     frequency of use.                                                          
                                                                                
                                                                               
HYK8SG, HYK8SH, HYK8SI, HYK8SJ, HYK8SK, HYK8SL, HYK8SM, HYK8SN, HYK8SO, HYK8SP: 
                                                                                
     How long has -- been taking this product? (months)                         
                                                                                
     This variable was created from the two-part (number and unit) question K8, 
     and indicates the long-term duration of use. The conversion factor was 12  
     months/year.  When supplements were reported as prescription drugs and     
     then moved as part of the data editing process (see note for variable HK1A)
     much of the information was not directly transferable.  For example,       
     categories for duration of taking drugs (HYK12S variables) did not         
     always match those listed for the corresponding question for               
     vitamin/mineral supplements (HYK8S variables).  Responses reported in weeks
     were rounded to the nearest month, whereas response in months and years    
     were transferred directly.

     Primary drug class code                                                    
                                                                                
     Up to three drug class codes were assigned for each reported prescription  
     medication.  These 4-digit codes were supplied by the Product Information  
     Branch, Center for Drug Evaluation and Research at the U.S. DDHS Food and  
     Drug Administration.  The version of these codes that was used was last    
     updated in October 1994.  The primary drug class code assignment was based 
     on the known drug action.  For example, all cardiovascular drugs that were 
     beta-adrenergic blocking agents were assigned the drug class code 0512     
     (beta blockers).  See Appendix 2 for listing of codes.

     This variable contains the second drug class codes for each prescription   
     drug reported.  If medical condition for which the medication was used (as 
     reported in question K11) was different than the known drug action, then a 
     secondary drug class code was entered.  For example, a cardiovascular drug 
     that was a beta-adrenergic blocking agent was assigned the drug class code 
     0512 (beta blocker) as the primary drug code, and a secondary drug class of
     0502 (antiarrhythmic).  If the reason provided did not relate to any of the
     known actions of the drug, then only the medication-specific (primary)     
     class code was assigned.  See Appendix 2 for listing of codes.

     Tertiary drug class code                                                   
                                                                                
     This variable contains the tertiary drug class codes for each prescription 
     drug reported.  If medical condition for which the medication was used (as 
     reported in question K11) was different than the primary drug class, then a
     secondary, and tertiary drug class code was entered.  For example, a       
     cardiovascular drug was assigned the drug class code 0512 (beta blocker) as
     the primary drug code, a secondary drug class code of 0502                 
     (antiarrhythmics), and a tertiary code of 0506 (antihypertensives).  If the
     reason provided did not relate to any of the actions of the drug, then only
     the medication-specific class code (primary) was assigned. See Appendix 2  
     for listing of codes.

     ICD-9-CM codes were used to classify the medical conditions reported in    
     question K11 for each prescription drug reported.  Conditions were coded to
     the forth digit ICD-9-CM level of specificity except in those cases where  
     the three digit ICD-9-CM code is the highest level of specificity. Some    
     conditions where no appropriate code was available in the Classification of
     Diseases and Injuries ICD-9-CM codes, were coded using V Codes -           
     Supplementary Classification of factors Influencing Health Status and      
     Contact with Health Services.  See Appendix 3 for listing of codes.

     For how long have -- been taking this medicine? (days)                     
                                                                                
     This variable was created from the two-part (number and unit) question K12 
     (standardized in days).  The conversion factors for weeks, months, and     
     years were 7, 30, and 365, respectively.  For medicines originally reported
     as supplements and moved in the data editing process, duration of use could
     not always be directly transferred.  The categories for duration of        
     supplement use in question K8 did not match those listed for the           
     corresponding question under prescription medicines (K12).  A response of  
     "less than one month" in K8 was changed to blank but applicable (8-fills)  
     in K12 for medicines that were originally recorded as supplements.

     Interviewers determed whether or not the one or more sections of the       
     Household Youth Interview was possibly unreliable.  This determination was 
     subjective and based on a number of factors including the relationship of  
     the respondent (proxy) to the sample person (HYM1), mental competency of   
     the respondent (proxy), etc.  Because there was norecord of the            
     sections that were possibly unreliable, all interviews were retained.
