National Longitudinal Study of Adolescent to Adult Health (Add Health), 1994-2008 [Restricted Use]

The National Longitudinal Study of Adolescent to Adult Health (Add Health) is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-95 school year. The Add Health cohort has been followed into young adulthood with four in-home interviews, the most recent in 2008, when the sample was aged 24-32. 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. The fourth wave of interviews expanded the collection of biological data in Add Health to understand the social, behavioral, and biological linkages in health trajectories as the Add Health cohort ages through adulthood.

《从青少年到成年人的国家纵向健康研究》（Add Health）是一项针对美国1994-95学年七至十二年级学生的全国代表性样本的纵向研究。Add Health队列的成员已进入青年期，并通过四次家庭访谈进行跟踪，最近一次访谈在2008年，当时样本年龄为24至32岁。Add Health将关于受访者社会、经济、心理和身体福祉的纵向调查数据与家庭、邻里、社区、学校、友谊、同伴群体和恋爱关系等背景数据相结合，为研究社会环境与青少年行为如何与青年期健康和成就结果相关联提供了独特的机遇。第四次访谈将Add Health中的生物数据收集范围扩大，以理解随着Add Health队列成员进入成年期，其健康状况轨迹中的社会、行为和生物学联系。
