摘　　要：目的探讨日常生活能力在老年人睡眠时长和抑郁症状的中介效应,为预防和缓解老年人抑郁症状提供政策参考。方法利用2020年CHARLS数据库中8240例≥60的老年人为研究对象。使用相关分析、回归分析探讨老年人睡眠时长、日常生活能力、抑郁症状之间的关系,bootstrap检验关键变量与日常生活能力之间的中介效应。结果老年人抑郁症状阳性率占比40.93%。睡眠时长与日常生活能力呈正相关(r=0.106,P<0.01),睡眠时长与抑郁症状呈负相关(r=-0.265,P<0.01),日常生活能力与抑郁症状呈负相关(r=-0.314,P<0.01)。中介效应结果显示,日常生活能力(效应值=-0.009,Boot 95%CI:-0.014~-0.004)显著中介了睡眠时长与抑郁症状之间的联系。结论睡眠时长和日常生活能力均是老年人抑郁症状的影响因素,日常生活能力在老年人睡眠时长和抑郁症状之间起到部分中介作用。相关卫生部门和社区应采取有针对性的干预措施,以减缓抑郁症状对老年人群心理健康的影响。Objective To investigate the mediating effect of daily living ability on the relationship between sleep duration and depression symptoms in the elderly,to provide policy references for the prevention and alleviation of depression symptoms in this population.Methods The study utilized data from 8240 individuals aged 60 and above from the 2020 CHARLS database.Correlation and regression analyses were conducted to explore the relationships among sleep duration,daily living ability,and depression symptoms in the elderly,with the Bootstrap method employed to test the mediating effects of key variables on daily living ability.Results The positive rate of depression symptoms among the elderly was found to be 40.93%.Sleep duration was positively correlated with daily living ability(r=0.106,P<0.01)and negatively correlated with depression symptoms(r=-0.265,P<0.01).Additionally,daily living ability was negatively correlated with depression symptoms(r=-0.314,P<0.01).The results of the mediating effect analysis indicated that daily living ability significantly mediated the relationship between sleep duration and depression symptoms(effect value=-0.009,Boot 95%CI:-0.014 to-0.004).Conclusion Both sleep duration and daily living ability are influencing factors of depression symptoms in the elderly,with daily living ability playing a partial mediating role between sleep duration and depression symptoms.Relevant health departments and communities should implement targeted intervention measures to mitigate the impact of depression symptoms on the mental health of the elderly population.
