摘　　要：目的了解农村轻度认知障碍(MCI)老年人中睡眠障碍的患病率,并分析两种疾病的关联。方法对1485名农村老年人进行了现场问卷调查,其中有效问卷1422份。调查内容包括基本人口学信息、蒙特利尔认知评估量表以及睡眠障碍的疾病信息。结果睡眠障碍在MCI老年人中的患病率为40.58%,与认知正常老年群体相比,两者睡眠障碍患病率差异不存在统计学意义。独立样本T检验结果显示,睡眠障碍老年人的认知水平低于没有睡眠障碍的老年人(t(1420)=3.12,P=0.002);具体而言,在执行功能(t(1420)=3.92,P<0.001)、视觉(t(1420)=2.75,P=0.006)和定向力(t(1420)=2.75,P=0.006)方面,睡眠障碍老年人的表现水平低于没有睡眠障碍的老年人。logistic回归分析结果显示,在控制年龄、性别、教育水平等基本人口信息后,睡眠障碍的老年人患MCI的风险是没有睡眠障碍的1.75倍(OR:1.75,95%CI:[1.34,2.28])。结论睡眠障碍在农村老年人中的患病率较高,但在MCI和认知正常老年人中的患病率差异不存在统计学意义。睡眠障碍可能显著影响老年人的执行功能、视觉能力和定向力等认知功能,并可能增加MCI的患病风险。Objective To investigate the prevalence of sleep disorders in the elderly with mild cognitive impairment(MCI)in rural communities and the associations between cognitive functions and sleep disorders.Methods An on-site questionnaire survey was conducted among 1485 elderly residents,of which 1422 were valid.The survey included basic demographic information,Montreal Cognitive Assessment and disease information of sleep disorders.Results The prevalence of sleep disorder in the elderly with MCI was 40.58%,which was not significantly different from that in those with normal cognition.The results of independent sample t-test showed that the cognitive level of the elderly with sleep disorder was significantly lower than that of the elderly without sleep disorder(t(1420)=3.12,P=0.002);Specifically,there were significant differences between the two groups in executive function(t(1420)=3.92,P<0.001),vision(t(1420)=2.75,P=0.006)and orientation(t(1420)=2.75,P=0.006).The results of logistic regression analysis showed that after controlling for age,gender and education,the risk of MCI in the elderly with sleep disorders was 1.75 times(OR=1.75,95%CI=[1.34,2.28])higher than that in the elderly without sleep disorders.Conclusions The prevalence of sleep disorders in the rural elderly is high,but there is no significant difference between MCI and cognitively normal elderly.Sleep disorders may significantly affect the executive function,visual ability,and orientation of the elderly,and increase the risk of MCI.
