摘要

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 ages 6 months through 74 years. A similar survey, NHANES I, was conducted during the period 1971-1975. During NHANES II, data were collected by means of a household questionnaire, medical histories, dietary questionnaires, a physical examination, spirometry trials, electrocardiograms, body measurements, pure tone audiometry, speech, allergy tests, x-rays, a medication/vitamin usage questionnaire, a behavior questionnaire and laboratory analyses of blood and urine samples. There were a total of 20,647 sample persons 12-74 years of age of whom 18,447 were interviewed and 14,479 were examined. This tape contains health histories for the 18,447 people 12-74 years of age interviewed during NHANES II.
