摘要/Abstract

摘要： 目的探讨社区老年人衰弱与认知功能之间的关系,并探讨心理弹性在其中的中介作用。方法采用Tilburg衰弱量表、心理弹性量表简版、简易精神状态评估量表和自编一般情况调查问卷对827例社区老年人进行调查。结果社区老年人衰弱发生率为30.11%,认知功能下降发生率为21.04%。衰弱与心理弹性(r=-0.45,P<0.01)、认知功能(r=-0.34,P<0.01)呈负相关,心理弹性与认知功能呈正相关(r=0.39,P<0.01)。模型拟合结果显示,心理弹性在衰弱与认知功能之间起中介作用(β=-0.13,P<0.01)。结论社区老年人的衰弱对认知功能有直接预测作用,且受心理弹性的中介效应调节,今后可采取措施降低老年人衰弱程度,提升其心理弹性水平,以减少认知功能衰退发生率,促进老年人的健康老龄化。

Abstract: Objective To explore the relationship between frailty and cognitive function of community-dwelling elderly, and to analyze the mediating effect of resilience between frailty and cognitive function. Methods A total of 827 community-dwelling elderly were investigated by Tilburg Frailty Indicator(TFI), 10-item Connor-Davidson Resilience Scale(CD-RISC-10), Mini-Mental State Examination (MMSE) and self-made general condition scale. Results The incidence rate of frailty and cognitive decline among community-dwelling elderly was 30.11% and 21.04%, respectively. Frailty was significantly negatively correlated with resilience(r=-0.45, P<0.01) and cognitive function(r=-0.34, P<0.01), and resilience was significantly positively correlated with cognitive function (r=0.39, P<0.01). The model fitting results showed that resilience played a mediating role in the relationship between frailty and cognitive function(β=-0.13, P<0.01). Conclusions Frailty has a direct predictive effect on the cognitive function of community-dwelling elderly, and it is moderated by the mediating effect of resilience. Reducing the frailty degree of the elderly and improving the level of resilience might reduce the incidence of cognitive decline and promote the healthy aging of the elderly.
