o New questions were added and the wording of some questions was changed
during the course of the six-year survey. Users should be aware that
these changes may account for large numbers of records containing
blanks in these variables. In particular, the Family Questionnaire
section B on Health Insurance and section F on Family Characteristics
contain quite a few questions that were changed during the survey.
There were three different versions of some of those questions.
o Two aspects of NHANES III, especially, should be taken into account
when conducting any analyses: the sample weights and the complex survey
design. With the extensive oversampling of blacks, Mexican Americans,
young children and older adults in NHANES III, it is IMPERATIVE that
sample weights be used in all analyses in order to interpret the
findings correctly.
o Examine the range and frequency of values of a variable before
conducting analyses of data. The range may include unusual or
unexpected values. The frequency counts may be useful to determine
which analyses may be worthwhile.
o Interviewers rated the reliability of responses at the completion of
interviews. While all data collected are presented on this data file,
it is strongly recommended that responses rated "unreliable" should be
omitted from analyses.
o The Public Health Service Act (Section 308(d)) provides that the data
collected by the National Center for Health Statistics (NCHS), Centers
for Disease Control and Prevention, may be used ONLY for the purpose of
health statistical reporting and analysis. Any effort to determine the
identity of any reported case is prohibited by this law. NCHS does all
it can to assure that the identity of data subjects cannot be
disclosed. All direct identifiers, as well as any characteristics that
might lead to identification, are omitted from the dataset. Any
intentional identification or disclosure of a person or establishment
violates the assurances of confidentiality given to the providers of
the information. Therefore, users will:
1. Use the data in this dataset for statistical reporting and analysis
only.
2. Make no use of the identity of any person or establishment discovered
inadvertently and advise the Director, NCHS, of any such discovery.
3. Not link this dataset with individually identifiable data from other
NCHS or non-NCHS datasets.
By using these data, you signify your agreement to comply with the above-
stated statutorily based requirements.

GENERAL NOTES
o Numeric responses: Users should pay careful attention to questions
throughout NHANES III forms that are coded using two variables to record a
numeric response. The first variable contains the numeric portion of the
response and the second variable contains the units of measure. All of
these questions were recoded and replaced with standardized variables. For
example, responses in days, weeks, or months were recoded to number of times
per month.
o Rounding:
Responses that included fractional answers were rounded off when the
code categories were integers only. Fractions of less than 1/2 were
dropped; fractions of 1/2 or more were rounded up to the next whole integer
An example would be a response of 2 1/2 years which was rounded up to
3 years. Rounding was not done if units of measure allowed conversion of
fractional responses to an integer response. For example, a response of "1
1/2 packs of cigarettes" was converted to 30 cigarettes since the variable
allowed for expression of the answer in cigarettes as well as packs.
o Ranges:
If a response was given as a range or an imprecise number, rules were
used to code the response if the interviewer was unable to obtain an
exact number. For example, if a person said "in my early 50's", "in my mid-
30's", or "in my late 20's", the response was coded as 53 for "early 50's",
35 for "mid-30's", and 28 for "late 20's". If a range was given, the mid-
point of the range was used and any fractions were rounded off. For
example, a response of "30-35" was coded as 33.
o Which AGE variable to use:
Each sample person has an age at screening interview which is almost always
calculated using the date of interview and the date of birth. For each
examined sample person, there is an age at exam calculated using date of
exam and date of birth. Since the sample person was selected into the
survey based on age at screening interview and since this determined which
components of the survey he/she was eligible to receive, the most appropriate
age to use in any NHANES III analyses is "age at interview" (HSAGEI and
HSAGEU). There are a few exceptions to this rule. In certain analyses of
infants and young children, age at exam may be a more appropriate choice
because of the many changes that occur in growth and development during
this time period. In general, age at screening interview is the appropriate
age variable to use in most NHANES III analyses.
o Multiple responses possible:
The user should be aware that there are a number of questions asked during
the NHANES III interviews where multiple affirmative responses were possible.
In these situations, the number of "yes" responses to the question will be
more than the number of sample persons who were asked the question.
o Sections of questionnaires not included in data file:
Some questions or sections of questionnaires are not released on public
use data files. These data are the sensitive and personal data that were
collected in the survey for the purpose of longitudinal follow-up studies
and are not released by NCHS for confidentiality reasons. Some sections of
the questionnaires were used for administrative purposes (Diabetes Review
in the household youth questionnaire) and are not being released. Other
sections (Vitamin, Mineral and Medicine Usage) are still being processed
and will be released at a later time.
o Changes in questionnaires during six-year survey:
Every attempt was made to keep the questions exactly the same during
the entire six years of NHANES III. However, because of certain Public
Health Service requirements, some additional questions were added at
the end of the third year of NHANES III. The primary areas where these
changes occurred were in the household family questionnaire but other
components changed as well. The family questionnaire changes occurred
in the areas of income questions, food security, and health insurance
coverage. The NHANES III public release data files have been created
to reflect the version of the questionnaires published in "Plan and
Operation of the Third National Health and Nutrition Examination Survey,
1988-94", that is, the versions used at the end of the second phase of
the survey. For those "new" questions not asked until the last three
years of the survey, all the data are blank for those persons interviewed
during the first three years.
o Unlikely or inconsistent responses or data values:
The NHANES III data were edited carefully for skip pattern and range
errors as well as for consistency between related questions. Somewhat
arbitrary but reasonable limits were usually set regarding what extreme
values were possible or impossible. If a response was determined to
be impossible, that response was edited and recoded "blank but applicable".
Food frequency questions were an exception; even if the frequency stated
seemed highly improbable, answers were not changed. Analysts are free
to exclude extreme values if they wish. Respondents were not always
consistent in their answers to questions, either because of misunder-
standing or not remembering precisely. Inconsistent responses were
examined, but if it could not be determined which was the "correct"
response, then both values may have been left as coded.
o Other and specify responses:
Responses to "other" and "specify" were recoded ("backcoded") to
existing categories, if possible. For responses that could not be
recoded, new code categories were created if the information was
deemed analytically useful. Caution should be used in interpreting
data from these new categories because there is no way of knowing
which other respondents would have selected one of the new categories
if they had been given the options.

APPENDIX B - GEOGRAPHIC CODES
Codes for variables HFA6XR and HFHFIPR
Based on FIPS PUB 10-3 Codes for Countries, Dependencies,
Areas of Special Sovereignty, and Their Principal Administrative Divisions.
This appendix describes a subset of the overall FIPS PUB 10-3 codes.
Although all countries are represented, only selected lower divisions (i.e.
states or provinces) within each country are listed. In NHANES III,
questions regarding birthplace or place lived longest were asked in the
context of a country or a state within the Unites States. However, some
respondents gave additional detail. This is reflected in the Countries for
which we have provided lower division-level codes. To ignore this level of
detail simply use the first two characters of the code. Conversely, some
respondents gave answers that were too vague (i.e. Europe). These are
represented by the numeric fill-value categories at the end of this code
table.
