This study aimed to explore the mediating effects of ADL and depression on the relationship between sleep quality and HRQOL among older people in rural China, while also exploring the moderating impact of loneliness. The study gathered data from a household survey conducted among 1587 Chinese rural older adults (mean age = 73.63 years). The collected data was analyzed using SPSS version 23.0 software (IBM, New York, USA) and the PROCESS macro version 4.0 program. The findings indicated a significant correlation between sleep quality, ADL, depression, loneliness and HRQOL. ADL and depression exhibited a chain mediation effect on the relationship between sleep quality and HRQOL. Notably, the association between sleep quality and HRQOL was entirely mediated by ADL and depression. Additionally, loneliness acted as a moderator in the relationship between ADL and HRQOL. The findings of this study suggest that interventions focusing on sleep quality should prioritize strategies for enhancing older adults' ADL and depression as integral components of promoting older adults' HRQOL.
本研究旨在探讨日常生活活动能力和抑郁在睡眠质量与农村老年人健康相关生活质量之间的关系中的中介作用，同时探讨孤独感的调节作用。该研究通过对 1587 名中国农村老年人进行家庭调查收集数据（平均年龄=73.63 岁）。使用 SPSS 版本 23.0 软件（IBM，纽约，美国）和 PROCESS 宏版本 4.0 程序对收集的数据进行分析。研究结果表明，睡眠质量、日常生活活动能力、抑郁、孤独感与健康相关生活质量之间存在显著相关性。日常生活活动能力和抑郁在睡眠质量与健康相关生活质量之间存在链式中介效应。值得注意的是，睡眠质量与健康相关生活质量之间的关联完全由日常生活活动能力和抑郁介导。此外，孤独感在日常生活活动能力与健康相关生活质量之间的关系中起调节作用。本研究结果表明，关注睡眠质量的干预措施应优先考虑增强老年人日常生活活动能力和抑郁的策略，将其作为促进老年人健康相关生活质量的组成部分。
