摘要： 目的探讨农村地区轻度认知障碍老年人睡眠时长与睡眠效率对其认知功能的影响。方法采用MoCA和匹兹堡睡眠质量指数量表(PSQI)调查114例农村轻度认知障碍老年人的认知功能及睡眠质量,根据睡眠效率(睡眠时间/床上时间×100%)将其分为＞85%组、75%~85%组、＜75%组,按睡眠时长将其分为≤6 h组、(6,8)h组、≥8 h组。对各组间的认知功能进行比较分析。结果除抽象维度外,轻度认知障碍老年人MoCA其他维度评分均与PSQI各维度评分有明显相关性;睡眠时长≤6 h组与≥8 h组在MoCA总分、视空间与执行功能、命名、延迟回忆、PSQI总分、主观睡眠质量、睡眠时间、睡眠效率方面差异具有统计学意义(P＜0.05);睡眠效率＞85%组与＜75%组,在MoCA总分、命名、定向、PSQI总分、主观睡眠质量、入睡时间、睡眠时间、睡眠效率方面差异具有统计学意义(P＜0.05)。结论农村地区轻度认知障碍老年人睡眠时长与睡眠效率对其认知功能影响显著。关注和提高农村地区轻度认知障碍老年人睡眠质量,将有助于其认知功能的改善。

Abstract: Objective To explore the effects of sleep duration and sleep efficiency on cognitive function of the elderly with mild cognitive impairment in rural areas. Methods A total of 114 elderly with mild cognitive impairment in rural areas were enrolled in this study. Pittsburgh Sleep Quality Index (PSQI) and Montreal Cognitive Assessment (MoCA) were used to investigate the sleep quality and cognitive function. According to sleep efficiency, the elderly were divided into 3 groups: > 85% group, 75%-85% group and <75% group. According to the sleep duration, they were divided into 3 groups: ≤6 h group, (6,8) h group and ≥8 h group. Results Except for the abstract dimension, the scores of MoCA showed significant correlation with the scores of PSQI in the elderly people with mild cognitive impairment in rural areas (P＜0.05). Compared with ≥8 h group, the scores of MoCA including the dimensions as visual space and executive function, naming, delayed recall were significantly lower, and the scores of PSQI, including the dimensions as subjective sleep quality, sleep time, sleep efficiency were significantly higher in ≤6 h group (P<0.05). Compared with ＜75% group, the scored of MoCA including the dimensions as naming and orientation were significantly higher, and the scores of PSQI, including the dimensions as subject sleep quality, sleep latancy, sleep time and sleep effitiency were significantly lower in ＞85% group. Conclusions Sleep duration and sleep efficiency have significant effects on the cognitive function in the elderly in rural areas. Therefore, improving the sleep quality of the elderly with mild cognitive impairment in rural areas will contribute to the improvement of the cognitive function.
