This editorial perspective comments on the evidence that mental health is deteriorating among children and young people at the same time as the impact of poor mental health is more impairing. It discusses the methodological difficulties in detecting a ‘true’ change in prevalence. There are particular gaps in the evidence from low‐ and middle‐income countries and also in relation to autism spectrum disorders. The evidence in high‐income countries points to recent increases in anxiety, depression and self‐harm in teenagers, particularly young women. We need more longitudinal data to disentangle the potential explanations for these changes.

社论观点：为什么我现在确信情绪障碍在许多国家的年轻人中越来越普遍。

这篇社论评论了这样的证据，即儿童和年轻人的心理健康正在恶化，同时心理健康状况不佳的影响越来越大。它讨论了检测患病率“真实”变化的方法上的困难。来自低收入和中等收入国家的证据以及与自闭症谱系障碍有关的证据存在特殊差距。高收入国家的证据表明，最近青少年，尤其是年轻女性的焦虑、抑郁和自我伤害有所增加。我们需要更多的纵向数据来解开对这些变化的潜在解释。
