Drawing from the National Survey on Drug Use and Health (NSDUH; N = 611,880), a nationally representative survey of U.S. adolescents and adults, we assess age, period, and cohort trends in mood disorders and suicide-related outcomes since the mid-2000s. Rates of major depressive episode in the last year increased 52% 2005-2017 (from 8.7% to 13.2%) among adolescents aged 12 to 17 and 63% 2009-2017 (from 8.1% to 13.2%) among young adults 18-25. Serious psychological distress in the last month and suicide-related outcomes (suicidal ideation, plans, attempts, and deaths by suicide) in the last year also increased among young adults 18-25 from 2008-2017 (with a 71% increase in serious psychological distress), with less consistent and weaker increases among adults ages 26 and over. Hierarchical linear modeling analyses separating the effects of age, period, and birth cohort suggest the trends among adults are primarily due to cohort, with a steady rise in mood disorder and suicide-related outcomes between cohorts born from the early 1980s (Millennials) to the late 1990s (iGen). Cultural trends contributing to an increase in mood disorders and suicidal thoughts and behaviors since the mid-2000s, including the rise of electronic communication and digital media and declines in sleep duration, may have had a larger impact on younger people, creating a cohort effect.

利用全国药物使用与健康调查（NSDUH；N=611880）的数据，这是一项对美国青少年和成年人的全国代表性调查，我们评估了自 21 世纪中期以来情绪障碍和与自杀相关结果的年龄、时期和队列趋势。在过去一年中，12 至 17 岁青少年的重度抑郁发作率从 2005 年至 2017 年增加了 52%（从 8.7%增至 13.2%），18 至 25 岁的年轻人则增加了 63%（从 2009 年至 2017 年，从 8.1%增至 13.2%）。在过去一个月中，严重的心理困扰和与自杀相关的结果（自杀意念、计划、尝试和自杀死亡）在过去一年中也在 18 至 25 岁的年轻人中增加，从 2008 年至 2017 年增加了 71%（严重心理困扰），而在 26 岁及以上的成年人中，这种增加的情况则不太一致且较弱。分层线性模型分析将年龄、时期和出生队列的影响分开，表明成年人的趋势主要是由于队列的影响，从 20 世纪 80 年代初（千禧一代）到 90 年代末（iGen）出生的队列中，情绪障碍和与自杀相关的结果呈稳步上升趋势。自 21 世纪中期以来，导致情绪障碍和自杀念头和行为增加的文化趋势，包括电子通信和数字媒体的兴起以及睡眠时间的减少，可能对年轻人的影响更大，从而产生了队列效应。（APA，所有权利保留）。
