National Health and Nutrition Examination Survey

The National Health and Nutrition Examination Survey (NHANES) is a program conducted by the U.S. government that collects health and nutrition data from a representative sample of the population. Participants undergo physical exams, answer questionnaires, and provide blood and urine samples. This information helps understand the health status of Americans, track trends over time, and guide public health policies. NHANES covers various topics such as diet, chronic conditions, and environmental exposures, providing valuable insights to improve health and prevent disease for the entire population.
