摘要
目的:探讨健康促进行为与老年增殖型糖尿病视网膜病变(proliferative diabetic retinopathy,PDR)患者衰弱的关系,以及自我效能及孤独感的内在作用机制。方法:采用方便抽样法,选取2021年5月至2022年11月安徽省某眼科医院214例老年PDR住院患者为调查对象。采用衰弱量表、中文版健康促进生活方式量表-Ⅱ、自我效能量表和简化版孤独感量表对患者进行调查。采用Process软件Bootstrap法分析检验自我效能在老年PDR患者健康促进行为和衰弱间的中介作用以及孤独感在自我效能与衰弱关系间的调节作用。结果:共发放问卷220份,回收有效问卷214份,有效回收率为97.27%。有调节的中介效应分析表明,健康促进行为可显著负向预测衰弱(β=-0.508,P<0.01);健康促进行为和自我效能对衰弱的预测作用均显著(β分别为-0.191、-0.433,P<0.01),健康促进行为对自我效能的预测作用亦显著(β=0.063,P<0.01)。自我效能在健康促进行为对衰弱的影响中发挥部分中介作用,中介效应占总效应的14.76%;孤独感与自我效能的乘积项对衰弱的预测作用显著(β=0.255,P<0.01),孤独感可在自我效能对衰弱的中介作用中产生调节效应。结论:老年PDR患者健康促进行为通过自我效能影响衰弱,孤独感调节自我效能对衰弱的关系,有调节的中介模型成立。
Objective:To investigate the relationship between health promoting behavior and frailty in elderly patients with proliferative diabetic retinopathy(PDR),and the mediating effects of self-efficacy and loneliness.Methods:In an eye hospital of Anhui Province,214 elderly patients with PDR were selected from May 2021 to Nov 2022 by convenient sampling method.The Frailty Scale,Chinese Version of Health-Promoting Lifestyle Profile-Ⅱ,Self-Efficacy Scale and Simplified Loneliness Scale were used in this survey.Bootstrap method of Process software was used to analyze the mediating effect of self-efficacy on the relationship between health promoting behaviors and frailty in elderly PDR patients and the moderating effect of loneliness on the relationship between self-efficacy and frailty.Results:A total of 220 questionnaires were distributed and 214 valid questionnaires were returned,with valid response rate of 97.27%.Moderated mediation effect analysis suggested that health-promoting behaviors negatively predicted frailty(β=-0.508,P<0.01).Health promoting behaviors and self-efficacy had significant predictive effects on frailty(β=-0.191 and-0.433,P<0.01),and health promoting behaviors also had a significant predictive effect on self-efficacy(β=0.063,P<0.01).Self-efficacy played a partially mediating role between health promoting behaviors and frailty,and the mediating effect accounted for 14.76%of the total effect.The product term of loneliness and self-efficacy significantly predicted frailty(β=0.255,P<0.01),the mediating effect of self-efficacy on frailty was moderated by loneliness.Conclusions:The health-promoting behaviors of elderly patients with PDR affect frailty through self-efficacy,and loneliness moderates the relationship between self-efficacy and frailty.The moderated mediation model is established.
