This study aimed to examine changes in depression and anxiety symptoms from before to during the first 6 months of the COVID-19 pandemic in a sample of 1,339 adolescents (9–18 years old, 59% female) from three countries. We also examined if age, race/ethnicity, disease burden, or strictness of government restrictions moderated change in symptoms. Data from 12 longitudinal studies (10 U.S., 1 Netherlands, 1 Peru) were combined. Linear mixed effect models showed that depression, but not anxiety, symptoms increased significantly (median increase = 28%). The most negative mental health impacts were reported by multiracial adolescents and those under ‘lockdown’ restrictions. Policy makers need to consider these impacts by investing in ways to support adolescents’ mental health during the pandemic.

从 COVID-19 大流行之前到期间青少年抑郁和焦虑症状的纵向变化

这项研究旨在检查来自三个国家的 1,339 名青少年（9-18 岁，59% 为女性）样本中抑郁和焦虑症状从 COVID-19 大流行之前到头 6 个月的变化。我们还检查了年龄、种族/民族、疾病负担或政府限制的严格程度是否缓和了症状的变化。来自 12 项纵向研究（10 项美国、1 项荷兰、1 项秘鲁）的数据被合并。线性混合效应模型显示，抑郁而非焦虑症状显着增加（中位数增加 = 28%）。多种族青少年和处于“封锁”限制下的青少年报告了最负面的心理健康影响。政策制定者需要考虑这些影响，方法是在大流行期间投资支持青少年的心理健康。
