National Health and Nutrition Examination Survey

Why Participate?

The National Health and Nutrition Examination Survey (NHANES) is one of our nation’s greatest resources! It is a unique survey that combines interviews and physical exams. For more than 60 years, thousands of people like you have been part of NHANES, helping us understand the health challenges our nation faces.

By taking part in this rare opportunity, participants learn about their own health and help us learn valuable information about the health of people living in the United States.  There are many benefits to you and your family for participating.
