Survey description
The First National Health and Nutrition Examination Survey (NHANES I) was
conducted on a nationwide probability sample of approximately 32,000
persons 1-74 years of age. The NHANES I
sample was selected so that certain population groups thought to be at
high risk of malnutrition (persons with low incomes, preschool children,
women of childbearing age, and the elderly) were oversampled at preset
rates. On completion of the survey, 31,973 sample persons had been
interviewed; of these, 23,808 people were examined. Adjusted sampling
weights were computed within 60 age-sex-race categories in order to
inflate the sample so as to closely reflect the U.S. civilian
noninstitutionalized population 1-74 years of age at the midpoint of the
survey. Although a major emphasis of NHANES I was on nutrition and some
limited aspects of health, a subset of 3,854 persons 25-74 years of age
received a more detailed health examination. No oversampling of subgroups
of the population was done in this subsample, as it had been for the major
nutrition component. This subsample is representative of the U.S.
population 25-74 years of age at the midpoint of NHANES I. After the
nutrition survey was completed, the detailed medical examination was given
to adults 25-74 years of age. This portion of the survey is referred to as
the NHANES I Augmentation and was continued through October 1975, bringing
the total number of persons who received a detailed examination to 6,913.
Data from NHANES I are
organized by subject matter. The data files comprising the NHANES I
include a number of demographic and socioeconomic variables on each tape,
including age, gender, race, ethnicity, income, education, and marital
status.
