Depression and anxiety symptoms among returning workers during the COVID-19 period in East China

PURPOSE: To determine the prevalence of depression and anxiety and associated factors among returning workers with different epidemic experience in East China. METHODS: A cross-sectional study was conducted among 2435 employees from the enterprises located in Deqing (low-risk epidemic area) and Taizhou (high-risk epidemic area) of East China in March 2020. An online questionnaire covered information on sociodemographic and lifestyle factors as well as knowledge, attitude, behavior and experience about COVID-19. The Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7) were applied to assess depression and anxiety symptoms, respectively. Logistic regression model was used to estimate adjusted odds ratios (aORs) and their 95% confidence intervals (CIs) for depression and anxiety symptoms associated with risk factors. RESULTS: The participants were aged 36.3 ± 9.2 years on average, and nearly half of them were female. Overall, the prevalence of depression, anxiety and both were 19.4%, 12.3% and 9.8%, and decreased with age. After adjustment for covariates, 16 or more years of education, being a white-collar worker or working in the high-risk epidemic area were significantly associated with increased risks of both depression and anxiety, in contract regular physical exercise was associated with decreased risks of both mental disorders. CONCLUSION: The depression and anxiety problems were prevalent among returning workers during the COVID-19 period. Targeted psychological interventions should be developed and implemented to improve their mental health.
