The relationship between intergenerational financial support and depressive symptoms among older adults: Evidence from China Health and Retirement Longitudinal Study, 2011-2018

Aimed to investigate the effect of intergenerational financial support on depressive symptoms among older adults over time.Data were obtained from China Health and Retirement Longitudinal Study (CHARLS) 2011, 2013, 2015, and 2018. A finite distributed lag (FDL) model was employed, long-run cumulative effect was evaluated. 1426 respondents followed in four waves were included in FDL model. CES-D score was used to measure depressive symptoms, intergenerational financial support was defined as financial support received from older adults' children or grandchildren. Sociodemographic characteristics, health behaviors, social insurance, and social contact factors were controlled in the model.More than a third older adults in China had a CES-D score of 10 or higher. Intergenerational financial support has a significant long-run cumulative negative effect on older adults' depressive symptoms (CES-D scores: coef. = -0.674, P < 0.001; % with CES-D scores ≥10: Coef. = -0.154, P = 0.018). While, the intergenerational financial support in previous period exhibited a significant negative association with depressive symptoms, the 2, 3, and 4 periods did not reach statistical significance.Intergenerational financial support has a significant negative effect on older adults' depressive symptoms over time, while the effect may diminish. Programs need to be explored to support home-based eldercare to mitigate this diminished effect.
