The original purpose of the Add Health study was to help understand the causes of adolescent health and health behaviour with special emphasis on the effects of multiple contexts of adolescent life.
The cohort was then followed through their transition to adulthood and research turned to understanding the determinants and consequences of developmental and health trajectories from adolescence into adulthood.
Add Health combines longitudinal survey data on respondents social, economic, psychological and physical well-being with contextual data on the family, neighbourhood, community, school, friendships, peer groups, and romantic relationships, providing unique opportunities to study how social environments and behaviours in adolescence are linked to health and achievement outcomes in young adulthood. The fourth wave of interviews expanded the collection of biological data in Add Health to understand the social, behavioural, and biological linkages in health trajectories as the Add Health cohort ages through adulthood, and the fifth wave of data collection continues this biological data expansion (2016-2018).
