Prevalence and influencing factors of depressive symptoms among rural-to-urban migrant workers in China: A systematic review and meta-analysis

Background: Rural-to-urban migrant workers are a large group in China, and they are often more prone to mental health problems, especially depression. We expected to use meta-analysis to estimate the prevalence of depressive symptoms and the influencing factors of depressive symptoms among rural-to-urban migrant workers in China.

Methods: PubMed, Web of Science, Embase, Scopus, CINAHL Complete, PsycARTICLES, CNKI, Wan Fang, CBM, and Cochrane were searched on October 16, 2021. The data were analyzed using OR and random effect model in Revman5.3 and STATA 15 Software.

Results: We included 30 studies involving 43,884 rural-to-urban migrant workers. The prevalence of depressive symptoms among rural-to-urban migrant workers in China was 0.28 (95% CI:0.22, 0.34); Results of the meta-analysis showed that working hours, sleep status, self-rated health, financial condition, job satisfaction, marriage, and social support were correlated with depressive symptoms.

Limitations: The systematic review and meta-analysis included only cross-sectional studies, and more types of original studies on depressive symptoms of rural-to-urban migrant workers in China should be carried out in the future.

Conclusion: The prevalence of depressive symptoms among rural-to-urban migrant workers in China is 28%. Government departments can intervene early in the process to promote the mental health of this group based on influencing factors of depressive symptoms among rural-to-urban migrant workers in China.
