Pubertal transitions in mental health and behaviour: the PHASE-A study of social roleand lifestyle transitions

在过去四十年中，青年人中抑郁、焦虑、自残和药物滥用等问题有所增加。最近的研究表明，青春期通常是这些问题首次出现的时候。这项对4000名学生进行的为期五年的研究将探讨一个问题，即过早的社会转型（例如过早开始性行为）或有问题的社会转型（例如来自同龄人的欺凌）是否可以解释这些健康问题的增加，因为儿童通过青春期。

Over the past four decades problems such as depression, anxiety, self-harm and substance abuse have increased in young people. Recent research indicates that puberty is a time when these problems commonly first emerge. This five-year study of 4000 students will examine a question of whether social transitions that are too soon (e.g. early initiation of sex) or problematic (e.g. bullying from peers) may explain the increase in these health problems as children pass through puberty.
