Abstract:The second National Health and Nutrition Examination Survey (NHANES II), conducted during the period 1976-1980, was designed to measure and monitor the nutritional status and health of the U.S. population aged 6 months through 74 years. During NHANES II, data were collected by means of a household questionnaire, medical histories, dietary questionnaires, a physical examination, spirometry trials, electrocardiograms, body measurements, puretone audiometry, speech and allergy tests, X-rays, a medication/vitamin usage questionnaire, a behavior questionnaire, and laboratory analyses of blood and urine samples. Each file contains approximately 100 demographic variables, with the exception of the Model Gram and Nutrient Composition files which do not contain any demographics. The demographic data include information on the type of residence and housing, composition of the household, vehicles, languages spoken, income sources and amounts, food stamps and commodity foods, employment, age, race and national ancestry, sex, education, marital status, veteran status, and region of country. The universe for these surveys was the civilian noninstitutionalized population of the United States aged 6 months through 74 years. Using a stratified multistage probability sampling procedure that oversampled certain population groups thought to be at high risk of malnutrition (persons with low incomes, preschool children, and the elderly), 27,801 persons were selected from the universe. Of these, 25,286 were interviewed and 20,322 were medically examined (4,964 individuals were interviewed but not examined).
Universe:Non-institutionalized civilian population of the United States between the ages of 6 months to 74 years.
