深圳市老年人群睡眠状况与认知功能关联研究

目的 探讨深圳市老年人群睡眠状况与认知功能之间的关系。方法 以在深圳市某医院体检的老年人群为研究对象,分别采用匹兹堡睡眠质量指数量表（PSQI）和简易智力状态量表（Mini-Cog）完成该人群的睡眠状况和认知功能评估。采用Logistic回归分析睡眠状况与认知功能的相关性。结果 共纳入7 510名调查对象,其中男性占43.5%,女性占56.5%;60~69岁占68.4%,70~79岁占28.3%,仅有14.9%的老年人文化程度在小学及以下,87.5%为已婚,79.5%从不吸烟,85.6%从不饮酒,81.4%近半年规律锻炼身体。睡眠质量差的老年人占17.9%,认知功能障碍的老年人占10.5%。多因素Logistic回归分析显示,睡眠障碍（OR=1.250）和日间功能障碍（OR=1.128）是认知功能障碍的危险因素。结论 睡眠质量是影响老年人群认知功能的因素,良好的睡眠质量可能对认知功能起到一定的积极作用。建议在社区进行健康睡眠知识以及认知知识的宣教活动,提高老年人群的生活质量。

Correlation between sleep status and cognitive function in the elderly in Shenzhen

Objective To investigate the correlation between sleep status and cognitive function in the elderly in Shenzhen. Methods The data was collected from the survey results of elderly who underwent physical examination in hospital of Shenzhen. The Pittsburgh sleep quality index scale （PSQI） and the simple mental state scale （Mini-Cog） were used to evaluate the sleep status and cognitive function. Logistic regression was used to analyze the correlation between sleep status and cognitive function. Results A total of 7 510 subjects were included, including 43.5% males and 56.5% females, 68.4% aged 60-69 and 28.3% aged 70-79. Only 14.9% of the elderly had education level of primary school or below, 87.5% were married, 79.5% never smoked, 85.6% never drank, 81.4% had regular exercise in the past half year, and 17.9% and 10.5% of the elderly were found to have poor sleep quality and cognitive dysfunction. Multivariate Logistic regression showed that the sleep disorder （OR=1.250） and daytime dysfunction （OR=1.128） were risk factors of cognitive dysfunction. Conclusions leep quality is a factor affecting cognitive function of the elderly. Good sleep quality may play a certain positive role in cognitive function. It is suggested that healthy sleep knowledge and cognitive knowledge publicity activities should be carried out in the community to improve the quality of life of the elderly population.
