National Health and Nutrition Examination Survey (NHANES)

The National Health and Nutrition Examination Survey (NHANES) is a major program in the United States that gathers health data from a representative sample of people. Conducted by the Centers for Disease Control and Prevention (CDC), it combines interviews and physical examinations to assess the health, diet, and lifestyle of participants. The information collected helps researchers and policymakers understand health trends, identify public health issues, and evaluate nutrition and health interventions. NHANES data is pivotal for designing health programs and shaping policies to improve overall public health in the country.
