NHANES II (National Health and Nutrition Examination Survey, Second). Model Gram and Nutrient Composition. Catalog Number 5702 and 5703

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 analyses of blood and urine samples. There were a total of 27,805 sample persons of which 25,289 were interviewed and 20,325 were examined. The Model Gram tape consists of 2,607 food items with food groups; food codes; alpanumeric descriptions; preferred food model codes and gram conversion factors. The Nutrient Composition tape contains the actual nutrient analysis in 100 gram edible portions of all foods listed in the Model Gram tape. These tapes are essentially an interpretive tool for use as input to a computer analysis of NHANES II 24-Hour Recall dietary data, or data from a survey employing similar methodology.
