National Longitudinal Study of Adolescent Health (Add Health), 1994-2002: HIV Data [Restricted Use]

The National Longitudinal Study of Adolescent Health (Add Health) is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-1995 school year. The Add Health cohort has been followed into young adulthood with three in-home interviews, the most recent in 2001-2002, when the sample was aged 18-26. Add Health combines longitudinal survey data on respondents' social, economic, psychological, and physical well-being with contextual data on the family, neighborhood, community, school, friendships, peer groups, and romantic relationships, providing unique opportunities to study how social environments and behaviors in adolescence are linked to health and achievement outcomes in young adulthood. This component of the Add Health restricted data contains the Wave III HIV results data.
