摘要

The Second National Health and Nutrition Examination Survey (NHANES II), conducted during the period 1976-80, 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 from 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, puretone audiometry, speech and allergy tests, x-rays, a medication/vitamin usage questionnaire, a behavior questionnaire and laboratory analysis of blood and urine samples. There were a total of 27,801 sample persons of which 25,286 were interviewed and 20,322 were examined. This data tape contains demographic information, total nutrient intake reported during a 24-Hour Recall dietary interview, reported frequencies of consumption of foods from 18 food groups, and dietary information related to food consumption habits including vitamin-mineral usage and special diets.
