To investigate the mediating effects of daily activity ability and depression on pain status and subjective life expectancy in elderly patients with chronic diseases, and to provide suggestions and references for active aging.
Based on The China Health and Retirement Longitudinal Study (CHARLS) 2020 data, 5 768 patients with chronic diseases aged ≥60 years were selected as the study subjects, and Spearman correlation analysis was used to explore the correlation between pain, ability to perform activities of daily living, depression, and subjective life expectancy, and PROCESS 4.1 program Model 6 was used to construct the chain-mediated model.
Pain was positively correlated with impaired daily activity ability and depression (r=0.399, P<0.001; r=0.370, P<0.001), was negatively correlated with subjective life expectancy (r=-0.221, P<0.001); The mediating effects of daily activity ability and depression on pain and subjective life expectancy were significant, with simple mediating effects of -0.023 (95%CI: -0.031 to -0.016) and -0.042 (95%CI: -0.049 to -0.034), respectively. The chain mediation effect was -0.013(95%CI: -0.016 to -0.010). The total mediating effect of daily activity ability and depression on pain and subjective life expectancy was -0.078, accounting for 57.78%.
There is a chain mediated effect between daily activity ability and depression on pain status and subjective life expectancy in elderly patients with chronic diseases. With the popularization of primary medical and health services, the family doctor service team needs to improve the comprehensive management of elderly patients with chronic diseases, improve the subjective well-being of elderly patients with chronic diseases from pain management, daily activity intervention, depression regulation and other aspects, and prolong the subjective life expectancy.
