Study on the relationship between frailty and depression in middle-aged and elderly people with chronic diseases
Objective To explore the relationship between frailty and depression in middle-aged and elderly people with chronic diseases,and to analyze the chain mediating effect of perceived social support and resilience between frailty and depression.Methods From October 2020 to September 2021,elderly people with chronic diseases from the communities under the jurisdiction of 2 Community Health Service Centers in Tangshan in Hebei province were ran-domly selected as the research objects by using stratified cluster random sampling method.The general information questionnaire,Comprehensive Frailty Assessment Instrument(CFAI),Geriatric Depression Scale(GDS),Perceived Social Support Scale(PSSS),and the Connon-Davidson Resilience Scale(CD-RISC)were used to conduct face-to-face questionnaire survey.Results Frailty of middle-aged and elderly people with chronic diseases was positively cor-related with depression(r=0.267,P＜0.01),and significantly negatively correlated with perceived social support and resilience(r1=-0.252,r2=-0.372,P＜0.01).Perceived social support and resilience(r1=-0.336,r2=-0.365,P＜0.01)were positively correlated with frailty,and was significantly negatively correlated with depression.The mediating effects of perceived social support,resilience,and perceived social support → resilience between frail-ty and depression accounted for 20.0％,25.6％,and 7.1％of the total effects,respectively.Conclusion The frailty of middle-aged and elderly people can not only directly affect depression,but also indirectly affect depression through the independent mediating effect of perceived social support and resilience,and the chain mediating effect of per-ceived social support and resilience,respectively.
