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:
NHANES III Household Adult Data File (Catalog Number 77560)
NHANES III Household Youth Data File (Catalog Number 77550)

GUIDELINES FOR DATA USERS
Please refer to the following important information before analyzing data.
NHANES III Background Documents
o The Plan and Operation of the Third National Health and Nutrition
Examination Survey, 1988-94, (NCHS, 1994; U.S. DHHS, 1996) provides an
overview of the survey and includes copies of the survey forms.
o The sample design, nonresponse, and analytic guidelines documents on 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).

SURVEY DESCRIPTION
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 AND ANALYSIS GUIDELINES
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).
Appropriate Uses of the NHANES III Sample Weights
Final interview weight, WTPFQX6
Use only in conjunction with the sample interviewed at home and
with items collected during the household interview.
Final examination (MEC only) weight, WTPFEX6
Use only in conjunction with the MEC-examined sample and with
interview and examination items collected at the MEC.
Final MEC+home examination weight, WTPFHX6
Use only in conjunction with the MEC+home-examined sample and with
items collected at both the MEC and home.
Final allergy weight, WTPFALG6
Use only in conjunction with the allergy subsample and with items
collected as part of the allergy component of the exam.
Final CNS weight, WTPFCNS6
Use only in conjunction with the CNS subsample and with items
collected as part of the CNS component of the exam.
Final morning examination (MEC only) subsample weight, WTPFSD6
Use only in conjunction with the MEC-examined persons assigned to
the morning subsample and only with items collected in the MEC
exam.
Final afternoon/evening examination (MEC only) subsample weight, WTPFMD6
Use only in conjunction with the MEC-examined persons assigned to
the afternoon/evening subsample and only with items collected in
the MEC exam.
Final morning examination (MEC+home) subsample weight, WTPFHSD6
Use only in conjunction with the MEC- and home-examined persons
assigned to the morning subsample and with items collected during
the MEC and home examinations.
Final afternoon/evening examination (MEC+home) weight, WTPFHMD6
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 HFA6XR. 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."

GENERAL INFORMATION
The NHANES III Examination Data File contains data collected in the
mobile examination center (MEC) as well as data collected during the
home examination. The documentation pertaining specifically to the
Examination Data File is divided into four main sections. The first
section, "General Information," provides information about the contents
of the Examination Data File. The second section, "Data File Index,"
includes a brief description of all the variables on the data set and
shows the standard name of each variable and its position in the data
set. The third section, "General Notes, Item Descriptions, Codes,
Counts, and Notes" provides for each component, a description, the
standard variable name and a brief description of the values
that variable can take on, a count of the frequency of occurrence of
each value, notes by variable, and appendices as necessary. "References"
are provided in the fourth section.
Components administered in both the MEC and the home (e.g., spirometry,
body measurements, physical function evaluation) are combined in this
file if data collection methods were comparable. The file includes
information from all the examination components as well as from all the
questionnaires administered in the examination center and during the
home examination. In addition, data on total nutrient intakes, food
sufficiency, intake of plain drinking water, and salt use are also
included as part of this file. However, detailed information about the
individual foods reported by respondents during the dietary interview
are contained in a separate NHANES III Dietary Data File. Data from
blood and urine specimens are not contained in this file, but are in a
separate NHANES III Laboratory Data File. Data from two examination
components, electrocardiography (ECG) and radiography of the hands and
knees, are not included in this file. ECG data will be released later
with comparable data from NHANES I and NHANES II. The x-ray data will
also be released later, after the images have been digitized. See the
Table of Contents for a complete list of components included in this
NHANES III data release. Since eligibility for examination components
was determined by the age of the examinee, the components of this file
are in order according to the target age group for each component, from
youngest to oldest.
Sample persons were examined in the MEC within four weeks of the
household interview. However, a home examination was scheduled for
those aged 2-11 months or 20 years and over who were frail or unable to
come to the MEC. The home examination was designed to gather certain
physical and physiological information on sample persons in their own
homes through a subset of components normally done in the MEC. These
components were: body measurements, venipuncture, spirometry, cognitive
testing, and physical performance testing. Interviewed persons who
completed at least one test or examination at the home were defined as
home-examined.
Staff recorded all examination data directly into an automated data
collection system. All staff received intensive initial training, and
formal retraining programs were conducted throughout the survey to
ensure that high skill levels were maintained. Details on survey
instruments and forms, training manuals, and data collection
procedures are published elsewhere (U.S. DHHS, 1996b).
Data processing and editing were performed to ensure internal data
consistency within components. Processing procedures are described in
each chapter of the this file. Notes are provided for standardized and
recoded variables, and for variables requiring additional information.
In some cases exceptions to the NHANES III conventions made in order to
enable NHANES III results comparisons with results from earlier surveys
or other studies. Such exceptions are described in the introduction to
the affected component or in individual variable notes.
One should note that for components such as the Dental Examination and
Audiometry which include negative value responses, value labels that
include ranges use a hyphen to indicate a range, from negative to
positive. For example, a range of -10 to 105 is written as -10-105.
Since NHANES III is based on a complex, multistage sample design,
appropriate sampling 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.
The final MEC examination weight, WTPFEX6, should be used for analysis
of the questionnaires and measurements administered in the MEC (except
for the allergy and central nervous system tests, which were performed
on half-samples and have their own weights), as well as for a combined
analysis of measurements from the MEC examinations and associated
medical history questions from the household interview. The final
MEC+home examination weight, WTPFHX6, should be used only in
conjunction with the MEC+home examined sample, and only with items
collected in both the MEC and the home. The analyst will find, however,
there are no weights for older examined persons since most of them are
overweight anyway and, therefore, basically self-weighting. The
weighting variables WTPxxxx) are included on the household questionnaire
data files which also include information on survey design and basic
demographic variables that may be linked to data in this file by using
the unique survey participant identifier, SEQN. In addition, a few
select weighting and demographic variables are included on this file for
basic, preliminary analyses.

DEMOGRAPHIC DATA: NOTES
Screener Questionnaire
DMPSTAT: Examination/interview status
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.
DMARETHN: Race-ethnicity
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
independently were not included. Other household members who were
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
note for Household Size (HSHSIZER).
HSHSIZER: Household Size
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).
DMPCNTYR: County FIPS codes for United States counties with populations of
500,000 and more
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.
DMPFIPSR: State FIPS codes for United States counties with populations of
500,000 and more
These state FIPS codes identify counties with populations of 500,000+
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.
DMPCREGN: Census region
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.
Survey Design Data
SDPPHASE: Phase of NHANES III survey
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
NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996).
Sampling Weights
WTPFQX6, WTPFQX1, WTPFQX2: Total NHANES III and phase-specific final
interview weights
These sampling weights should be used only for items collected during
the household interviews. To compute final interview weights, final
basic weights were first adjusted for nonresponse to household
interview, then post-stratified to the unpublished Current Population
Survey 1990 (Phase 1) and 1993 (Phase 2) population control estimates of
the U.S. population adjusted for undercount. For details, see
Weighting and Estimation Methodology (U.S. DHHS, 1996) and NHANES III
Analytic and Reporting Guidelines (U.S. DHHS, 1996).
WTPFEX6, WTPFEX1, WTPFEX2: Total NHANES III and phase-specific final MEC
examination weights
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
post-stratified to the unpublished Current Population Survey 1990
(Phase 1) and 1993 (Phase 2) population control estimates of the U.S.
population adjusted for undercount. For details, see Weighting and
Estimation Methodology(U.S. DHHS, 1996) and NHANES III Analytic and
Reporting Guidelines (U.S. DHHS, 1996).
WTPFHX6, WTPFHX1, WTPFHX2: Total NHANES III and phase-specific MEC+home
examination weights
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
post-stratified to unpublished Current Population Survey 1990 (Phase 1)
and 1993 (Phase 2) population control estimates of the U.S. population
adjusted for undercount. No separate sampling weights were computed for
home examinees. For details, see Weighting and Estimation Methodology
(U.S. DHHS, 1996) and NHANES III Analytic and Reporting Guidelines
(U.S. DHHS, 1996).
WTPFALG6, WTPFALG1, WTPFALG2: Total NHANES III and phase-specific allergy
examination subsample weights
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
1) and 1993 (Phase 2) population control estimates of the U.S.
population adjusted for undercount in the final step. For details, see
Weighting and Estimation Methodology (U.S. DHHS, 1996) and NHANES III
Analytic and Reporting Guidelines (U.S. DHHS, 1996).
WTPFCNS6, WTPFCNS1, WTPFCNS2: Total NHANES III and phase-specific central
nervous system (CNS) examination subsample final weights
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
Population Survey 1990 (Phase 1) and 1993 (Phase 2) population control
estimates of the U.S. population adjusted for undercount in the final
step. For details, see Weighting and Estimation Methodology
(U.S. DHHS, 1996) and NHANES III Analytic and Reporting Guidelines
(U.S. DHHS, 1996).
WTPFSD6, WTPFSD1, WTPFSD2: Total NHANES III and phase-specific morning
session MEC examination subsample final weights
These subsample weights are for special analyses where fasting time may
be an important factor. They were computed for persons aged 12 years
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
weights were first adjusted for the random half selection, then
adjusted for the non-response to assigned session, and finally,
post-stratified to the unpublished Current Population Survey 1990 and
1993 Population control estimates of the U.S. population adjusted for
undercount. Eligible MEC-examined persons who were assigned to the morning
session and examined in another session have a sampling weight of zero and
should be excluded in analyses. For details, see Weighting and Estimation
Methodology (U.S. DHHS, 1996) and NHANES III Analytic and Reporting
Guidelines (U.S. DHHS, 1996).
WTPFMD6, WTPFMD1, WTPFMD2: Total NHANES III and phase-specific afternoon/evening
session MEC examination subsample final weights
These subsample weights are for special analyses where fasting time
might be an important factor. They were computed for MEC examined
persons aged 12 years and older who were scheduled and examined in the
afternoon or evening sessions. Sampled households in the survey were
randomly assigned to one of two groups -- morning session ("standard")
or afternoon/evening session ("modified") assignments. All sample

time may have differed from the instructed fasting time and can be
obtained from the variable PHPFAST in the NHANES III Laboratory Data File.)
compute these weights, final MEC examination weights were first adjusted
for the random half selection, then adjusted for the nonresponse to
assigned session, and finally, post-stratified to the unpublished Current
Population Survey 1990 and 1993 population control estimates of the U.S.
population adjusted for undercount. Eligible MEC examined persons who were
assigned to the afternoon or evening sessions and examined in
another session have a sampling weight of zero and should be excluded in
analyses. For details, see Weighting and Estimation Methodology
(U.S.DHHS, 1996) and NHANES III Analytic and Reporting Guidelines
(U.S. DHHS, 1996).
WTPFHSD6, WTPFHSD1, WTPFHSD2: Total NHANES III and phase-specific morning
session MEC+home examination subsample final post
stratified weights
These subsample weights are for special analyses where fasting time may
be an important factor. They were computed for MEC+home examined
persons aged 12 years and older who were scheduled and examined in the
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 instruction
varied by age and session assignments (Plan and Operations of the Third

of zero and should be excluded in analyses. For details, see Weighting and
Estimation Methodology (U.S. DHHS, 1996) and NHANES III Analytic and
Reporting Guidelines (U.S. DHHS, 1996).
WTPFHMD6, WTPFHMD1, WTPFHMD2: Total NHANES III and phase-specific afternoon/
evening MEC+home examination subsample final weights
These subsample weights are for special analyses where fasting time may
be an important factor. They were computed for MEC+home examined
persons aged 12 years and older who were scheduled and examined in the
afternoon or evening sessions. Sampled households in the survey were

analyses. For details, see Weighting and Estimation Methodology
(U.S. DHHS, 1996) and NHANES III Analytic and Reporting Guidelines
(U.S. DHHS, 1996).
WTPQRP1--WTPQRP52: Fay's BRR Replicate interview sample
To allow for alternative methods to estimate variance, 52 replicate
weights were computed using repeated sampling method where WESVAR or
other software that use repeated samples, can be used for estimating
variance. Fay's method (see Fay, 1990; Judkins, 1990) was used to draw
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
(U.S. DHHS, 1996) and NHANES III Analytic and Reporting Guidelines
(U.S. DHHS, 1996).
WTPXRP1--WTPXRP52: Fay's BRR Replicate weights for MEC- examined sample
To allow for alternative methods to estimate variance, 52 replicate
weights were computed using repeated sampling method where WESVAR or
other BRR type software can be used to estimate variance. Fay's method
(see Fay, 1990; Judkins, 1990) was used to draw 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 Fay's method. After this adjustment, weights
were further adjusted for nonresponse and were post-stratified using the
same procedure as the full sample final weights. These weights should
be used only for estimating variance of outcome measurements or
interview items from the MEC Examination. For details, see additional
information on this subject in Weighting and Estimation Methodology
(U.S. DHHS, 1996) and NHANES III Analytic and Reporting Guidelines (U.S.
DHHS, 1996).
Household Youth Questionnaire
HYAITMO: Age in months (Household Youth Interview)
Age in months was calculated by computing number of months between
Household Youth Interview date and the date of birth. It was created for
special analyses where exact age at the interview may be needed. This
computed age may be different from the self-reported age in HSAGEIR and
HSAGEU, or HSAITMOR. For most analyses, age reported in HSAGEIR (and
HSAGEU) should be used.
MEC Examination
MXPLANG: Language of MEC examination
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.
MXPSESSR: Examination session for MEC examinees
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.
MXPAXTMR: Age in months at MEC examination
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.
Home Examination
HXPAXTMR: Age in months at home examination
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.
HXPSESSR: Examination session for home examinees
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.

Examinations were conducted on all examinees by a trained physician in
the mobile examination center (MEC). The protocol for this component
did not detail any medical, safety, or other exclusions.
Because this component was administered in the examination center, the
MEC examination sample weight (WTPFEX6) should be used for data
analysis. For more information on the use of sample weights in NHANES
III data analysis, refer to the NHANES III Analytic and Reporting
Guidelines (U.S. DHHS, 1996b).
The examination was performed by a board-eligible physician. Depending
on the examinee's age, the examination included observation of gait,
eye, and limb abnormalities; a joint examination of upper and lower
extremities; blood pressure measurements; evaluation of heart and breath
sounds; Tanner staging and breast-size measurements; and bioelectrical
impedance analysis (BIA) resistance and reactance measurements.
Refer to Chapter 3 of the Physician Examiners Training Manual (U.S.
DHHS, 1996b) and Pulse and Blood Pressure Procedures for Household
Interviewers (U.S. DHHS, 1996b) for descriptions of data collection
procedures and methods.
Although the BIA measures were recorded during the physician's
examination, these data are included in the Body Measurements section
of this data file.
Three sets of blood pressure measurements were taken in the
examination center on examinees aged five years and over. For
children and adolescents (aged 5-19 years), three Korotkoff (K) sounds
were recorded: K1 (systolic); K4, muffling of pulse sounds
(diastolic); and K5, disappearance of pulse sounds (diastolic). For
adults (aged 20 years and over), only K1 (systolic) and K5 (diastolic)
measurements were obtained. All blood pressure determinations were
recorded to the nearest even number. Blood pressure measurements were
also taken by trained interviewers during the household interview, on
sample persons aged seventeen years and over. These data can be found
in the NHANES III Household Adult Data File as part of the Household
Adult Questionnaire in variables HAZA1-HAZNOK5R. Both physicians and
interviewers took measurements using a mercury sphygmomanometer (W. A.
Baum Co., Inc, Copiague, NY) according to the standardized blood
pressure measurement protocols recommended by the American Heart
Association (Frohlich, 1988).
In addition to taking part in an initial training course specific to
the NHANES III examination procedures, examining physicians
participated in a formal, annual re-training program. Their work in
the field was monitored for quality by consultants and NCHS staff who
visited the mobile examination centers; monitoring occurred once a month
in the earlier years and every three months during the latter part of
the survey.
For additional blood pressure quality control, physicians and
household interviewers received a day and a half of initial blood
pressure measurement training, were recertified quarterly, and were
retrained annually. Training consisted of instruction in the
recognition of Korotkoff sounds using videotaped blood pressure
examples, comparison of blood pressure readings with those of
instructors using double-headed stethoscopes, and practice with
volunteer subjects. Physicians and household interviewers who
exhibited end-digit preferences, high/low measurement bias, or lack of
consistent measurements repeated the training until their performances
were deemed satisfactory for certification. Physicians and household
interviewers were given hearing tests at the beginning of their
employment and yearly thereafter.
Note that the coded values for "Yes" (2) and "No" (1) responses in the
physician's examination vary from the usual coded values for "Yes" (1)
and "No" (2) found in most other places in the NHANES III data files.
They match the codes found on the Physician's Examination form (U.S. DHHS,
1996b).
Also note that a number of areas (joint examination, dermatitis,
chest, and heart examination) in the Physician's Examination allow for
multiple responses. For example, on the wrist examination (PEP4A,
PEP4A1, PEP4A2, and PEP4A3), the examining physician may have found both
tenderness and swelling (PEP4A1=2 and PEP4A2=2). Consequently, the
overall positive findings in the detailed questions (PEP4A1, PEP4A2,
and PEP4A3) may exceed the number of positive findings reported in the
lead question (PEP4A).
Moreover, individuals classified as having a positive finding in a
lead question may have an 8-fill, "Blank but applicable," in one of
the associated detailed questions. For example, 26 cases classified
as "Yes" in PEP1 (overall findings for locomotion) were classified as
"Blank but applicable" for PEP1A1 (limp or shuffle) instead of "Yes,
limp or shuffle" or "No findings." Here, the examining physician used
"Blank but applicable" to account for situations in which he/she was
unable to observe or examine the specific abnormality.
When blood pressure measurement data were edited and it was discovered
that examinees aged twenty years and over were missing one of a K1/K5
pair of blood pressure measurements, the remaining one was made "Blank
but applicable;" there were ten such cases. However, for examinees
under twenty years of age who lacked one or two of a set of K1/K4/K5
blood pressure measurements, a different approach was taken. There were
71 such cases with the overwhelming majority of the missing values being
K4 and K5. Because the literature on pediatric blood pressure suggests
that systolic blood pressure is the most reliable determination (Uhari,
1991), it was not desirable to delete this value if the associated K4
and/or K5 values were missing. Therefore, K1 values in the data set
were retained without the corresponding K4 or K5 values. This accounts
for discrepancies in counts between K1 and K5 determinations (between
PEP6G1 and PEP6G3, PEP6H1 and PEP6H3, and PEP6I1 and PEP6I3). Finally,
when K4 was equal to K5, K4 was coded as "Blank but applicable."
The analyst should be aware of the potential for observer bias when
analyzing these data. During the six years of the survey, the number
of examinations performed by each physician varied widely among the
twelve physicians, from as few as 199 to as many as 9,529.
Data processing and editing were performed to ensure internal data
consistency. Notes have been provided for variables requiring
additional explanation.

PEP3A2: In a wheelchair or stretcher
Sitting in a wheelchair did not mean necessarily that the
individual was confined to a wheelchair. Examinees deemed frail
or physically unable to maneuver in the MEC used a wheelchair
while being examined. Information about wheelchair use also can
be found in the MEC Physical Function Evaluation.
PEP3B2TL, PEP3B2TR, PEP3LLEG, PEP3RLEG: Amputee/cast, great toes and
legs findings
These variables were recoded to ensure consistency between the
first three and last three years of the survey. Therefore,
variable labels differ from those on the Physician's Examination
form (U.S. DHHS, 1996b). The three cases of a "Cast" finding
with no specific site noted (coded as 09) in PEP3LLEG and
PEP3RLEG represent the early procedure in which the physician
entered a finding for a cast anywhere on the leg (hip, knee, or
ankle). In later years, the physician specified where on the leg
the cast was located. During data editing, the specific cast
locations coded separately were incorporated into PEP3LLEG and
PEP3RLEG as codes "10 Cast hip," "11 Cast knee," and "12 Cast
ankle." In addition, if a joint was coded as amputated in
PEP3LLEG or PEP3RLEG, the great toe distal to the amputated joint
was coded as "3 Amputated above the toe." For example, if the
left leg was amputated below the knee and above the ankle joint
(code 06), the great toe variables PEP3B2TL and PEP3B2TR were
coded as "3 Amputated above the toe."
PEP3B2TR: Amputee/cast, right great toe
See note for PEP3B2TL.
PEP3BFL1-PEP3BFL5, PEP3BFR1-PEP3BFR5, PEP3LARM, PEP3RARM: Amputee/cast,
fingers and arms findings
These variables were recoded to ensure consistency between the
first three and last three years of the survey. Therefore,
variable labels differ from those on the Physician's Examination
form (U.S. DHHS, 1996b). The four cases of a "Cast" finding with
no specific site noted (coded as 09) in PEP3LARM and PEP3RARM
represent the early procedure in which the physician entered a
finding for a cast anywhere on the arm (shoulder, elbow, or
wrist). In later years, the physician specified where on the arm
the cast was located. During data editing, the specific cast
locations coded separately were incorporated into variables
PEP3LARM and PEP3RARM as codes "10 Cast shoulder," "11 Cast
elbow," and "12 Cast wrist." If a joint was coded as amputated
in PEP3LARM or PEP3RARM, the fingers distal to the amputated
joint were coded as "4 Amputated above the finger." For
example, if the left wrist joint was coded as amputated (code
07), the finger variables (PEP3BFL1-PEP3BFL5) were coded as "4
Amputated above the finger."
PEP3LARM: Left arm amputee/cast findings
See note for PEP3BFL1.
PEP3LLEG: Left leg amputee/cast findings
See note for PEP3B2TL.
PEP3RARM: Right arm amputee/cast findings

PEP5R: Central pulse rate
This variable is a 60-second pulse rate derived by multiplying
the central pulse count at 30 seconds by two.
PEP6DR: Radial pulse rate
This variable is a 60-second pulse rate derived by multiplying
the radial pulse count at 15 seconds by four.
PEP6F: Maximum inflation level (MIL)
The MIL was obtained to determine the highest level to which the
blood pressure cuff should be inflated. It represents a level 30
mm Hg higher than the point at which the radial pulse disappeared.
PEP6G3, PEP6H3, PEP6I3: K5 blood pressure measurements
Zero is considered a valid observation for diastolic (K5)
measurements when pulse sounds continue to be heard down to 0 mm
Hg.
PEP6H3: Second K5 blood pressure measurement
See note for PEP6G3.
PEP6I3: Third K5 blood pressure measurement
See note for PEP6G3.
PEPLEVEL: Medical referral level
Based on the results of the physician's examination, the examinee
was placed in one of the following three medical referral
categories (U.S. DHHS, 1996b):
Level I -- Major medical emergencies that warranted immediate
attention by a health care provider
Level II -- Major medical findings that warranted attention by a
health care provider within two weeks
Level III -- All other findings reported to the examinee
PEPMNK1R: Average K1, systolic blood pressure
This variable is the arithmetic mean of six or fewer K1
measurements obtained at the household interview (maximum of
three) and the MEC examination (maximum of three). If the
examinee did not have blood pressure measurements taken in the
examination center, this variable was calculated from measurements
taken at the household interview. All blood pressure
determinations were recorded to the nearest even number. However,
since the variable is an arithmetic mean, it may include odd
numbers.
PEPMNK5R: Average K5, diastolic blood pressure
This variable is the arithmetic mean of six or fewer K5
measurements obtained at the household interview (maximum of
three) and the MEC examination (maximum of three). Even if the
examinee did not have blood pressure measurements taken in the
examination center, this variable was calculated from
measurements taken at the household interview. All blood pressure
determinations were recorded to the nearest even number. However,
since the variable is an arithmetic mean, it may include odd
numbers. The arithmetic mean was calculated using only (K5)
measurements greater than zero. Any K5 measurements of zero were
set to missing when calculating the K5 arithmetic mean.
BODY MEASUREMENTS
Body measurements were recorded for all examinees by a trained
examiner in the mobile examination center (MEC). The protocol for this
component did not detail any medical, safety or other exclusions.
The body measurements examination included measures of weight, standing
height, lengths, skinfolds, circumferences, and breadths. In
cases when examinees had to leave the MEC early and were unable
to participate in the complete body measures component, at a
minimum, weight and standing height or recumbent length were
measured.
Persons aged under one year or 20 years and over who were examined only
in their homes were given a subset of the body measures. These measures
were taken by trained technicians who used equipment and procedures
comparable to those used in the mobile examination centers. Therefore,
the home examination body measures were incorporated into the body
measures data set.
To determine which subjects were home examinees, the DMPSTAT
variable (3=home-examined) should be used. When analyzing data
for combined home-examined and MEC-examined subjects, the
combined MEC- plus home-examined sample weights should be used
(WTPFHX6). When using only MEC items or measures, the MEC
examination sample weight should be used (WTPFEX6). For more
information on the use of sample weights in the NHANES III data
analysis, refer to the Analytic and Reporting Guidelines (U.S.
DHHS, 1996b).
The following are the names shown on the Home Examination form in the
Plan and Operation of the Third National Health and Nutrition
Examination Survey, 1988-1994 (original home exam variable name; new
name) for home examination body measures (NCHS, 1994, p. 313; U.S. DHHS,
1996b). In the home exam, the only body measures taken were weight (A1;
BMPWT), standing height (A2; BMPHT), arm circumference (A6; BMPARMCI),
and triceps skinfold (A5; BMPTRI). For infants aged less than one year,
recumbent length (A3; BMPRECUM) was measured instead of stature, and
head circumference (A4; BMPHEAD) was added. For examinees who received
only a home examination, the measures listed above are the only body
measures available for analysis. Values for all other body measures for
these examinees appear as blank.
Bioelectrical impedance analysis (BIA) data are considered a part
of body measurements and have been included with the body
measurement data. However, the BIA resistance and reactance
measures were recorded by the physicians in the physician's
examination component, hence the "PEP" variable prefix.
For general guidelines on standard procedures that were followed
for the anthropometric measures, refer to The Anthropometric
Standardization Reference Manual (Lohman, 1988). For specific
guidelines, the Anthropometric Procedures Video that demonstrates
the NHANES III anthropometric procedures in detail is available
from the U.S. Government Printing Office (U.S. DHHS, 1996a).
The MEC health technicians, ultrasonographers, dentists, and home
examination health technicians were trained by two trainers to do
the anthropometric measurements. The two trainers were
cross-standardized initially and then annually during the survey.
Group retraining occurred twice during the survey. Periodic
visits to the field by each of the trainers assured ongoing
quality control in the accuracy and reliability of the
procedures.
This data set includes body measurements for women who were
pregnant at the time of the exam. Analysts should determine
whether it is appropriate to exclude data for these women for a
given analysis. Pregnancy status information is found in the
variable MAPF12R in the MEC Adult Questionnaire and in the
variable MYPC17 in the MEC Youth Questionnaire.
During the editing process, outliers were scrutinized using
univariate and multivariate methods to help identify implausible
values. When there was insufficient information to conclude that
values were invalid, they were left in the data set. Analysts
should examine the data spread and consider whether it is
appropriate to include or exclude extreme values in a given
analysis.
Data processing and editing were performed to ensure internal
data consistency. Notes have been provided for variables
requiring additional explanation.

NOTES
BMPBMI: Body mass index
BMPBMI was computed from weight and standing height using the
following formula: BMPBMI=BMPWT/((BMPHT/100)**2).
BMPHTFLG, BMPRECFL, BMPWTFLG: Standing height, recumbent length, and
weight source flags
Weight, standing height, and recumbent length are fundamental
body measures essential to most analyses of other health
examination data. Therefore, during data editing, a special
procedure was established and followed only for those three
variables when the primary measures were missing. This
procedure allowed available alternate source data to be
substituted for missing primary source data. In selected
cases, when data were absent from the primary health
examination, the source of the substitution is indicated by a
derived indicator (flag) variable (i.e., BMPWTFLG, BMPHTFLG,
BMPRECFL). These substitutions were derived from tests on
the actual data and evaluated and selected using cross-
validations on the actual data; they yielded satisfactory
results with R-squared values and correlations. The flag
values range from 00 to 06, and corresponding interpretations
of these flag codes have been summarized as follows:
00 No substitution
01 Modeled from spirometry height (i.e., standing height
measured in the spirometry exam)
02 Direct substitution for standing height from spirometry
standing height
03 Modeled from interview reported value
04 Direct substitution for weight from reported weight
05 Direct substitution for standing height from measured
recumbent length
06 Direct substitution for recumbent length from measured
standing height
The approach to obtain substitutions for "Blank but
applicable" (8-filled) primary recumbent length, standing
height, and weight, ranked in order of data availability,
included:
Recumbent length (age 2-47 months)
Direct substitution from stature, if present, into recumbent
length (age 2-3 years)(code 06).
If no substitution was possible from stature, a sex-specific
model with reported length, race/ethnicity, age (mo),
education of adult reference person, and reported weight was
used (code 03).
Height (age 2-16 years)
Direct substitution from recumbent length (age 2-3 years)
(code 05).
Direct substitution from spirometry height (age 8-16 years)
(code 02)
If spirometry height was not available, a sex- and
year-of-age-specific model with reported height, race/ethnicity,
age (mo), education of adult reference person, and reported
weight was used (code 03).
Height (age 17 years and over)
A sex-specific model with spirometry height, reported
height, race/ethnicity, age (mo), and reported weight was
used (code 01).
If spirometry height was not available, a sex-specific model
with reported height, race/ethnicity, and age (mo) was used
(code 03).
Weight (age 2-23 months)
A sex- and year-of-age-specific model with reported weight,
race/ethnicity, age (mo), education of adult reference
person, and measured recumbent length was used (code 03).
Weight (age 2-11 years)
Sex- and year-of-age-specific model with reported weight,
race/ethnicity, age (mo), education of adult reference
person, and measured standing height was used (Code 03).
Weight (age 12-16 years)
Sex- and year-of-age-specific model with reported weight,
race/ethnicity, and measured stature was used (code 03).
Weight (age 17 years and over)
A sex-specific model with reported weight, reported weight
from bone density screener questionnaire, measured height,
race/ethnicity, and age (yr) was used (code 03).
If the above variables were not present, direct substitution
from reported weight was used (code 04).
BMPHTIN: Standing height (in)
BMPHTIN is standing height converted to inches from
centimeters and was calculated as BMPHTIN=BMPHT/2.54.
BMPRECFL: Recumbent length source flag
See note for BMPHTFLG.
BMPSRHIS and BMPSRWL: Self-reported height (in) and weight (lbs)
BMPSRHIS is a derived variable that converts reported height in
feet and inches to total inches. It is equal to the reported
height in feet multiplied by 12 plus the reported height in inches.
All NHANES III participants were asked to report their current
height in feet and inches and their weight in pounds. Reported
height (BMPSRHIS) and weight (BMPSRWL) information was obtained
from adolescents (aged 12 through 16 years) during the body
measures component just prior to the actual measurement of
weight (BMPWT) and height (BMPHT). For examinees of all other
ages, data for similar reported values can be found in the
Household Adult Questionnaire among persons aged over 17
years for height (HAM5S) and weight (HAM6S) and in the
Household Youth Questionnaire among persons aged less than
12 years for height (HYB18S) and weight (HYB19S). Note that
in the data editing process some unusual values for reported
height were observed. For persons aged 12 through 16 years,
values less than 3 feet were deleted and recoded as "Blank
but applicable" (8888).
BMPSRWL: Self-reported weight (lbs)
See note for BMPSRHIS.
BMPSUB, BMPSUP, BMPTHI, BMPTRI: Skinfolds
For NHANES III, the body measurements protocol specified
that skinfolds would be measured at four different anatomic
body sites. Independent measures were taken at each body
site by two technicians, resulting in a minimum of two
skinfold observations for each site.
If the difference between the two measurements at a given
site was within a pre-specified tolerance limit, no further
measurements were taken at that site. The tolerance limits
increased by 2 mm for every 10 mm measured. For the first two
measures, the first measure represents the base. Thus, from 0-10
mm, observations were acceptable if they differed from the base
measurement by 2 mm or less; from 10-20 mm, observations were
acceptable if they differed from the base measurement by 4 mm or
less; from 20-30 mm, observations were acceptable if they differed
from the base measurement by 6 mm or less, and so on. If
the difference between the two measurements at a given site
did exceed the tolerance limit, each technician repeated and
recorded a second measurement, resulting in a total of four
measurements at that skinfold site.
The summary skinfold values were computed as follows:
If data were available for the third and fourth measurements
and the difference between those measurements was within the
specified tolerance limit, then the summary value was the
mean of the third and fourth measurements. In all other
cases, the summary value was the mean of all available
skinfold measurements at that site.
Tolerance: Tolerance was defined using the base skinfold measure.
For the third and fourth measures, the third measure represents the
base.
If base > 0 and base <= 10 then tolerance is 2 mm
If base > 10 and base <= 20 then tolerance is 4 mm
If base > 20 and base <= 30 then tolerance is 6 mm
If base > 30 and base <= 40 then tolerance is 8 mm
If base > 40 then tolerance is 10 mm.
This approach resulted in a single skinfold value for each
of four anatomic locations
