TRAILS (TRacking Adolescents' Individual Lives Survey) is an ongoing, multidisciplinary research on the psychological, social and physical development of adolescents and young adults. More than 2700 participants have participated since they were about eleven years old. For over 20 years, these participants have been examined every 2 to 3 years, through questionnaires, interviews, tests and/or physical measurements. Data was collected not only from participants, but also their family members, teachers, peers, and partners. TRAILS consists of a population cohort (TRAILS: POP) and a clinical cohort (TRAILS: CC). Since 2015, participants’ children have been measured in the offspring study TRAILS NEXT.追踪青少年个体生活调查（TRacking Adolescents' Individual Lives Survey，以下简称TRAILS）是一项持续开展的多学科研究，旨在探索青少年与年轻群体的心理、社会及身体发展状况。该研究自参与者约11岁时启动，至今已有超过2700名研究对象参与其中。20余年来，研究团队每2至3年便通过问卷、访谈、标准化测评及身体测量等方式，对这些研究对象进行一次随访数据采集。研究数据不仅采集自研究对象本人，还涵盖其家庭成员、教师、同伴及伴侣的相关信息。TRAILS包含两个核心队列：一般人群队列（TRAILS: POP）与临床队列（TRAILS: CC）。自2015年起，研究团队通过子代研究项目TRAILS NEXT对参与者的子女开展数据采集与测评工作。
