What Is It?

The National Longitudinal Study of Adolescent to Adult Health (also known as Add Health, formerly the National Longitudinal Study of Adolescent Health) is a nationally representative study originally designed to examine how social contexts (such as families, friends, peers, schools, neighborhoods, and communities) influence teens' health and risk behaviors. The study is now examining how health changes over the course of early adulthood.
