Description
The National Health and Nutrition Examination Survey (NHANES) is a program of studies designed to assess the health and nutritional status of adults and children in the United States. The survey is unique in that it combines interviews and physical examinations. The NHANES program began in the early 1960s and has been conducted as a series of surveys focusing on different population groups or health topics. In 1999, the survey became a continuous program that has a changing focus on a variety of health and nutrition measurements to meet emerging needs. The survey examines a nationally representative sample of about 5,000 persons each year. These persons are located in counties across the country, 15 of which are visited each year. The NHANES interview includes demographic, socioeconomic, dietary, and health-related questions. The examination component consists of medical, dental, and physiological measurements, as well as laboratory tests administered by highly trained medical personnel. Indicators from this data source have been computed by personnel in CDC’s Division for Heart Disease and Stroke Prevention (DHDSP). The data can be plotted as trends and stratified by age group, sex, and race/ethnicity.
The data is collected from different populations and health topics from a representative sample each year of around 5,000 subjects located across the country, 15 of these persons are included every year.
The NHANES collects demographic, socioeconomic, dietary and health-related information as well as medical, dental and physiological conditions and laboratory tests. The data is used to determine the prevalence of major diseases and risk factors, assess nutrition status of the population and its association with prevention of diseases and promotion of health, epidemiological studies and research. This survey also dictates the standards for height, weight and blood pressure of the American population.
