睡眠质量对社区老年人认知衰弱影响的归因分析

目的 探究睡眠质量和睡眠时长对社区老年人认知衰弱的作用大小。方法 采用现况调查方法，利用匹兹堡睡眠质量指数量表(Pittsburgh Sleep Quality Index, PSQI)评估老年人的睡眠质量，中文版AscertainDementia-8(AD-8)量表评估认知状态，Frail衰弱量表评估躯体衰弱。采用logistic回归分析和多因素调整的人群归因危险度分析睡眠对认知衰弱的作用大小。结果 本研究共调查955名社区老人受试者，男性425名(44.5%),女性530名(55.5%)。认知衰弱的检出率为8.7%,睡眠障碍的检出率为24.5%。在调整性别、年龄、BMI、婚姻、体育锻炼、午睡、慢性病、身体疼痛、抑郁、焦虑等混杂因素后，睡眠障碍(OR=1.891,95%CI:1.087～3.291)和睡眠时间<6 h(OR=1.859, 95%CI:1.044～3.312)的老年人更易发生认知衰弱，认知衰弱的发生风险随着PSQI得分增加而逐渐上升。睡眠质量和睡眠时长对于认知衰弱人群归因危险度分别为25.53%和23.95%。结论 社区老年人睡眠质量与认知衰弱程度相关，睡眠质量差...

Attribution analysis on the influence of sleep quality on cognitive frailty of community-dwelling elderly people

Objective To explore the role of sleep quality and sleep duration in cognitive frailty of the elderly living in the communities. Methods This study is cross-sectional. The Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality of the elderly, the Chinese version of the Ascertain Dementia-8(AD-8)questionnaire was applied to evaluating cognitive status, and the Frail Scale was employed to appraise physical frailty. Logistic regression analysis and multivariate-adjustedpopulation attribution risk analysis were performed to identify the effect of sleep on cognitive frailty. Results In this study, a total of 955 community-dwelling elderly subjects were surveyed, including 425 (44.5%) males and 530 (55.5%) females. The detection rate of cognitive frailty was 8.7%, and the detection rate of sleep disorder 24.5%. Multivariate logistic analysis showed that after adjusting for mixed factors like gender, age, body mass index, marriage, physical exercise, noontime snooze, chronic disease, body pain, depression and anxiety,senior citizenswith sleep disorder (OR=1.891, 95%CI:1.087-3.291) and sleep time < 6 hours (OR=1.859, 95%CI:1.044-3.312) were more likely to develop cognitive frailty. The risk of cognitive frailty increased with the gradual increment of PSQI score. The attributable risk of sleep quality and sleep duration to the cognitive frailty population was 25.53% and 23.95%, respectively. Conclusion The sleep quality of the elderly living in the communities was related to the degree of cognitive frailty. Poor sleep quality and short sleep duration were important factors leading to cognitive frailty in this study population. Taking targeted measures to intervene in sleep quality may be an important approach to alleviate cognitive frailty of the elderly.
