The National Health and Nutrition Examination Survey (NHANES) is an ongoing research survey designed to measure the health and nutritional status of the population of the United States. The 1971-1975 NHANES (NHANES I) included a nationally representative sample of about 23,808 persons age 1 to 74 who were both interviewed and examined, and another 8,165 individuals who were interviewed but not examined. NHANES uses a combination of interviews, physical examinations, and laboratory tests to collect data. All persons 25-74 years of age who completed a medical examination during NHANES I (n = 14,407) also constituted the cohort for the NHANES Epidemiological Followup Study.
