|Title:||Health and Nutrition Examination Survey I, 1971-1975 [United States]: General Well-Being|
|Primary Investigator(s):||United States Department of Health and Human Services. National Center for Health Statistics (NCHS)|
|Abstract:||The National Health and Nutrition Examination Surveys (Cycle I) were designed to measure the nutritional status and health of the U.S. population aged 1-74 years and to obtain more detailed information on the health status and medical care needs of adults aged 25-74 years in the civilian noninstitutionalized population. Information for all examined sampled persons in each of these National Health and Nutrition Examination Surveys (NHANES I) was obtained by means of a household interview, a general medical history, a 24-hour dietary intake recall interview, a food frequency interview, a food program questionnaire, a general medical examination, dental, dermatological, and ophthalmological examinations, anthropometric measurement, hand-wrist x-rays (of persons ages 1-17 only), and 24 hematological, blood chemistry, and urological laboratory determinations. In addition to this information, some respondents were given more specific tests such as x-rays of the chest and hip and knee joints, audiometry, electrocardiography, goniometry, spirometry, pulmonary diffusion and tuberculin tests, and additional laboratory determinations. The universe for the NHANES I survey was the civilian noninstitutionalized population, ages 1-74, of the United States at the midpoint of the survey (November 1, 1972). A multistage stratified probability sample of clusters of persons was used to obtain a total of 32,331 sample persons of which 31,973 were interviewed and 23,808 were examined. A total of 6,913 examinees ages 25-74 received a detailed examination.|
|Universe:||Non-institutionalized civilian population of the United States, 1 to 74 years of age (except those persons residing on Indian reservations).|
