Depression among schoolchildren and adolescents aged 9-17 years during the outbreak of COVID‑19 in Beijing: a cross-sectional online survey.

The COVID-19 outbreak and related confinement have highly impacted psychological health among children and adolescents. This study aimed to explore the potential risk factors for depression among primary and middle school students and provide advices for psychological interventions during the outbreaks. An online cross-sectional survey was conducted among 18 primary and middle school students via quota sampling in Beijing during March 2020. The Center for Epidemiological Studies Depression Scale (CES-D) was used to assess depression. Differences between characteristics and depression were examined by chi-square tests. Multivariate logistic regression was used to reveal the potential risk factors for depression. A total of 7377 participants were included. The proportion of depression was 29.7%. Students in rural areas, with higher school categories, in graduating grades, with poor or excessive sleep duration, and without daily exercise were associated with a higher proportion of depression. Furthermore, students with a higher knowledge performance of COVID-19 showed a lower proportion of depression (odds ratio [OR] = 0.900, 95% confidence intervals [95% CI]: 0.888-0.913). Students who worried about academic performance (OR = 1.919, 95% CI: 1.718-2.144) or COVID-19 infection (OR = 1.450, 95% CI: 1.268-1.658) exhibited a high proportion of depression. The proportion of depression among primary and middle school students was negatively associated with the knowledge score and positively associated with their worry. Our findings suggest that psychological intervention might be more necessary for students with specific characteristics.
