NHANES is one of our nation’s greatest health information sources! It is how we learn about the health and nutrition of adults and children in the United States.
The information NHANES collects is used to provide important health statistics. Public health officials, legislators, and doctors use the information collected in NHANES to develop good health policies, create health programs and services, and increase the knowledge about health concerns for the nation.
Here are just a few of the important questions NHANES data has helped answer.
- What percent of adults in the U.S. have high blood pressure, high cholesterol or diabetes?
- Are babies and children growing at a healthy rate?
- Have people in the U.S. been exposed to harmful chemicals through food or other exposures?
The first NHANES program began in 1960. Since 1999, the survey has examined about 5,000 people in 15 different counties across the country each year. Each participant makes an important contribution to the study, representing approximately 65,000 others in the country like them. Learn more about NHANES history.
