Abstract:
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.
