About Add Health

Add Health began in 1994-95 as the first-ever national study to follow over 20,000 adolescents into adulthood. You were part of this landmark study designed by researchers at the University of North Carolina and funded by the National Institutes of Health. The information you gave back then helped researchers across the country understand how adolescent experiences, the people they know, and the places they live, influence health as they become adults.

Add Health is getting ready for its fifth interview wave in 2015, 20 years after the first one when you were a teen. The purpose of this next step in the study is to uncover how health changes as you get older. What we learn from this next survey and health exam can help guide social and public health policies in America.

You have made Add Health one of the most important studies on the health of young people, a study that will improve the lives of future generations. To keep this important research going, we need your help to update our records about the best way to get back in touch with you. All the information you provide will be kept strictly confidential and will be used for research purposes only.

This study is voluntary, and you may choose not to take part in any of it. If you are able to help us by completing another interview, we will be able to pay you for your time.
