摘　　要：目的调查山东省农村慢性病老年人衰弱在睡眠质量和生活质量间的中介作用,为提高农村慢性病老年人的生活质量提供依据。方法采用多阶段分层整群抽样的方法选择样本。利用Fried衰弱表型(FP)、匹兹堡睡眠质量指数量表(PSQI)、欧洲五维健康量表(EQ-5D)对3243名老年人进行调查。应用SPSS 24.0中的Process V3.3插件对衰弱的中介效应进行检验。结果相较于农村非慢性病老年人,农村慢性病老年人的衰弱、睡眠质量和生活质量得分更低(均P<0.001)。衰弱得分与睡眠质量得分呈正相关(r=0.29,P<0.001),衰弱得分(r=-0.43,P<0.001)、睡眠质量得分(r=-0.36,P<0.001)与生活质量得分均呈负相关。衰弱在睡眠质量与生活质量间起中介作用,中介效应占总效应的32.26%。结论衰弱在农村慢性病老年人睡眠质量与生活质量间起部分中介作用,应关注农村慢性病老年人睡眠质量与衰弱,提高其生活质量。Objective To investigate the mediating role of physical frailty between sleep quality and quality of life(QoL),so as to provide reference for improving QoL of rural elderly with chronic diseases.Methods Multistage stratified cluster sampling method was used for sampling.A total of 3243 rural elderly were investigated with Frailty Phenotype(FP),Pittsburgh Sleep Quality Index(PSQI)and EQ-5 D.The mediating effect of physical frailty was examined using SPSS 24.0 plugin,Process V3.3.Results Compared with rural elderly without chronic diseases,those with chronic diseases had significantly lower scores of physical frailty,sleep quality and QoL(P<0.001).Physical frailty was positively correlated with sleep quality(r=0.29,P<0.001).Physical frailty(r=-0.43,P<0.001)and sleep quality(r=-0.36,P<0.001)were negatively correlated with QoL.Physical frailty played a mediating role between sleep quality and QoL,accounting for 32.26%of the total effect.Conclusion Physical frailty has a partial mediating effect on sleep quality and QoL.Due attention should to paid to sleep quality and physical frailty of rural elderly with chronic diseases to improve their QoL.
