The National Longitudinal Study of Adolescent to Adult Health (Add Health) is a comprehensive longitudinal study that tracks a nationally representative sample of over 20,000 adolescents who were in grades 7-12 during the 1994-95 school year. The study was initiated in response to a Congressional mandate aimed at understanding adolescent health and has since evolved to examine health trajectories into adulthood. We access the public-use data sets from the main site here.
