[The COVID-19 pandemic-How did it affect the mental health of children?]

Background: The COVID-19 pandemic has had a substantial impact on the daily life of children and adolescents due to lockdowns, contact restrictions, closings of childcare, schools and leisure facilities. Objective: This article examines the impact of the pandemic on the mental health of children and adolescents in Germany. Material and methods: In the population-based longitudinal COPSY study (COVID-19 and Psychological Health) 1600 parents of children aged 7-17 years old and 1000 children and adolescents aged 11-17 years old completed established questionnaires at 5 online survey points (t1: May and June 2020 to t5: September and October 2022). For comparison, pre-pandemic data were obtained from the representative BELLA study. Results: During the pandemic the portion of children and adolescents, who reported a low health-related quality of life, increased from pre-pandemic 15% to 48% in the first year of the pandemic and improved in year 3 to 27%. This is still substantially above pre-pandemic levels. Similar trajectories were found for mental health problems which rose from 18% (pre-pandemic) to 31% and improved in year 3 to 23%. For anxiety and depression, the changes were similar except that depressive symptoms returned to pre-pandemic levels in year 3. The physical activity of almost one third of the youth was still very low in year 3. Conclusion: The mental health of children and adolescents was ignored during the pandemic for a long time. Now support and allocation of funding is urgently needed to mitigate the negative mental health effects and prevent further impairment by new crises.
