Description
The National Health Examination Survey, Cycle I (NHES I) was conducted on a
nationwide probability sample of approximately 7,800 persons 18-79 years of
age. Upon completion of the
cycle, 7,710 sample persons had been interviewed; of these, 6,672 were
examined. Adjusted sampling weights were computed to inflate the sample so
as to closely reflect the 111 million persons 18-79 years of age in the noninstitutionalized civilian population
of the United States at the midpoint of the survey.
Data from NHES I are organized by subject. The person and demographic
characteristics data is a master intended for use in conjunction with any or
all other data in the set. It contains demographic, socioeconomic, and
geographic classification information not available on most of the other
data tapes, along with the sample weight for each examined person. A uniform
sequence file number on all data permits the user to merge any of the tapes.

Description
The National
Health Examination Survey, Cycle II (NHES II) was conducted on a nationwide
probability sample of 7,417 children 6-11 years of age. Of the 7,417
children selected for the
sample, 7,119 (96 percent) were examined. Adjusted sampling weights were
computed to inflate the sample so as to reflect the 24 million children in
the U.S. population at that time in terms of age, sex, and certain other demographic characteristics.
NHES II contains responses to detailed structured questionnaires for medical
and developmental histories; responses to school questionnaires; results of
medical, dental, and psychological examinations, and vision and hearing
tests; and anthropometric measurements.

Description
The National
Health Examination Survey, Cycle III (NHES III) was conducted on a
nationwide probability sample of 7,514 youths 12-17 years of age. Of the
7,514 youths selected for the
sample, 6,768 (90 percent) were examined. Adjusted sampling weights were
computed in order to inflate the sample so as to closely reflect the 23
million youths in the U.S. population at that
time in terms of age, sex, and certain other demographic characteristics.
Because the same basic sampling plan was used in Cycle III as in the earlier
Cycle II, nearly one-third of the children examined in Cycle II were also
examined in Cycle III. In the Cycle III Extended Data Tape (EDT), provision
has been made for the user to identify sample persons examined in both
surveys and to create from the Cycle II Integrated Data Tape (IDT) and the
Cycle III EDT a composite data set for longitudinal studies.
The NHES III data contains responses to detailed questionnaires for medical
and developmental histories; responses to school questionnaires; results of
medical, dental, and psychological examinations, and vision and hearing tests; anthropometric measurements; and
certain x-rays and laboratory tests.
