Detailed Objective: This study:
  • collects data on diet, food consumption, and health status as part of the National Health and Nutrition Examination Survey (NHANES);
  • develops and modifies survey questions to improve the measurement of the relationship between diet and health for low-income individuals; and
  • supports inclusion of a battery of food security questions.

The purpose of the survey, administered by the U.S. Department of Health and Human Services, is to provide nationally representative information on the health and nutritional status for the population of the United States. The Third National Health and Nutrition Examination Survey (NHANES III) was the seventh in a series of large health examination surveys that began in 1960. In 1970, the nutrition component was expanded to provide data which assessed nutritional status and dietary practices.

The sample for this study of the U.S. population is selected from households in counties across the United States. About 40,000 persons 2 months of age and over are selected, including large samples of both young and old persons. In previous surveys, about 12,000 of the sample persons were black Americans, 12,000 were Mexican-Americans, and the remaining 16,000 were of all other race and ethnicity groups.

Some of the 30 topics investigated in the National Health and Nutrition Examination Survey III were: high blood pressure, high blood cholesterol, obesity, passive smoking, lung disease, osteoporosis, HIV, hepatitis, helicobacter pylori, immunization status, diabetes, allergies, growth and development, blood lead, anemia, food sufficiency, dietary intake including fats, antioxidants, and nutritional blood measures.

A sampling frame has been developed and questions are being pretested for reliability. Data collection is underway and will be completed by the end of the year 1999. The key variables of interest to the Economic Research Service include dietary intake and nutritional status, anthropometric measurements, use of vitamin and mineral supplements and medications, tobacco and alcohol use, physical activity, and sociodemographic characteristics.
