To explore the correlation among sleep quality, physical frailty, and cognitive function in the older adults in community, and to explore the mediating role of sleep quality.
A total of 1,182 community-based older adults were investigated with frailty phenotype (FP), Pittsburgh sleep quality index (PISQI), Montreal cognitive assessment (MoCA) and self-made general information questionnaire.
The incidence of physical frailty among the older adults in the community was 25.8% and the incidence of cognitive decline was 19.5%. Cognitive function was negatively correlated with physical frailty ( = -0.236, < 0.01) and sleep quality ( = -0.558, < 0.01). Sleep quality was positively correlated with physical frailty ( = 0.337, < 0.01).
The physical frailty of the older adults has a direct prediction effect on cognitive function, and is regulated by the mediating role of sleep quality. Sleep quality partially mediates the relationship between cognitive dysfunction and physical frailty, which is a new insight into the study of cognition and physical frailty in the older adults. In the future, we can take measures to improve the sleep quality of the older adults, so as to reduce the occurrence of cognitive dysfunction and physical frailty of the older adults.
探讨社区老年人睡眠质量、身体虚弱与认知功能的相关性，并探讨睡眠质量的中介作用。
采用衰弱表型（FP）、匹兹堡睡眠质量指数（PISQI）、蒙特利尔认知评估（MoCA）和自制一般情况问卷，对 1182 名社区老年人进行调查。
社区老年人身体虚弱的发生率为 25.8%，认知功能下降的发生率为 19.5%。认知功能与身体虚弱呈负相关（ = -0.236， < 0.01），与睡眠质量呈负相关（ = -0.558， < 0.01）。睡眠质量与身体虚弱呈正相关（ = 0.337， < 0.01）。
老年人的身体虚弱对认知功能有直接的预测作用，且受睡眠质量的中介作用调节。睡眠质量部分中介了认知功能障碍与身体虚弱之间的关系，这为研究老年人的认知和身体虚弱提供了新的视角。未来可以采取措施改善老年人的睡眠质量，从而降低老年人认知功能障碍和身体虚弱的发生。
