Summary 

The National Health and Nutrition Examination Survey (NHANES) is a nationally representative, ongoing research survey designed to measure the health and nutritional status of adults and children in the United States. NHANES uses a combination of interviews, physical examinations, and laboratory tests to collect data; interviews include questions concerning demographics, diet, conditions, and health status information, while the examination component consists of medical, dental, and physiological measurements. Blood, urine, and other samples are collected for a variety of laboratory tests and are also saved for a national probability sample of genetic material.
