The
National
Longitudinal Study of Adolescent Health
The National Longitudinal Study of Adolescent Health (Add Health) is a
nationally representative study that explores the
causes of health-related behaviors of adolescents in grades 7 through

how social contexts (families, friends, peers, schools, neighborhoods,
and communities) influence adolescents' health and risk behaviors.
