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.TRAILS（追踪青少年个体生活调查，TRacking Adolescents' Individual Lives Survey）是一项持续开展的多学科研究，旨在探究青少年与年轻群体的心理、社会及躯体发展轨迹。自研究启动以来，已有超过2700名参与者在约11岁时加入研究队列。在过去20余年中，研究团队每2至3年便通过问卷、访谈、测评及躯体测量等方式，对这些参与者进行一次随访调研。研究数据不仅来源于参与者本人，还涵盖其家庭成员、教师、同伴及伴侣的相关信息。TRAILS 包含人群队列（TRAILS: POP）与临床队列（TRAILS: CC）两大子队列。自2015年起，针对参与者后代的子代研究TRAILS NEXT正式启动，对该部分人群开展相关测评工作。
