【 摘 要 】

Abstract Background Some studies have shown that childhood socioeconomic status (SES) can influence the development and progression of depression in adulthood. This study aimed to analyze the effects of childhood SES on depressive symptoms in individuals of middle-old age and examine the potential mediating role of life satisfaction based on national data in China. Methods Data were derived from the 2018 China Health and Retirement Longitudinal Study (CHARLS) data. A total of 17,129 individuals who were aged 45 years and older were included. The dependent variable was depressive symptoms in middle-old age. Childhood SES was the independent variable, and life satisfaction was the mediator. This study controlled four factors: general demographic characteristics, adult SES, childhood adversity and health and living status. Pearson correlations and hierarchical multiple regression analysis were performed, and the Baron and Kenny method was used to test the mediating role. Results The score of depressive symptoms among all participants was 7.88 ± 6.65. Gender, age, adult SES, childhood adversity and health and living status all affected the development of depression symptom in middle-aged and elderly individuals in China. After adjusting for all covariates, the higher the childhood SES, the lower the depressive symptom score (β = − 0.422, P < 0.001). Life satisfaction had a partial mediating effect between childhood SES and depressive symptoms. Low childhood SES may improve life satisfaction (β = 0.051, P < 0.001) and life satisfaction indirectly decreases depressive symptom scores (β = − 0.403, P < 0.001). Conclusions Life satisfaction was a partial mediator between childhood SES and depressive symptoms in middle and old age. Improving life satisfaction may serve as an intervention to reduce the incidence of depression symptoms in the future.
