National Health and Nutrition Examination Survey
NHANES is a survey research program conducted by National Centers for Health Statistics (NCHS), designed to assess health and nutritional status of adults and children in the United States. The survey integrates interviews and physical examinations. The interviews include demographics, socioeconomic, dietary and health-related questions, physical examinations including medical, dental, physiological measurements and laboratory tests. NHANES can be used for epidemiological studies and health sciences research, which can help develop public health policies, programs and services.
NHANES offers a rich variety of health and clinical data. It gives national results that can be compared to local findings. NHANES can be used to develop data-driven hypotheses as well as provide data that can be used for writing grants.
