摘要： 目的探究社会隔离与睡眠质量及两者的交互作用对老年人认知功能的影响。方法于2021年10~12月采用分层抽样法,从蚌埠市辖区内抽取520例老年人进行调查,分别使用Lubben社会网络量表简表(Lubben Social Network Scale,LSNS-6)、匹兹堡睡眠质量指数量表、蒙特利尔基础评估量表(Montreal Cognitive Assessment-Basic,MoCA-B)评估老年人的社会隔离、睡眠质量、认知功能情况,采用Logistic回归分析和交互作用分析三者之间的关联。结果 506例老年人中,存在社会隔离166例(32.8％)、睡眠障碍138例(27.3％)、认知功能障碍116例(22.9％)。调整年龄、文化程度、居住状况、婚姻状况、合并慢性病情况后,二元Logistic回归分析结果显示,社会隔离(OR=3.637,95％CI:2.174～6.205)、睡眠障碍(OR=3.308,95％CI:1.970～5.556)是老年人发生认知功能障碍的影响因素。二者相加交互作用分析结果显示,同时存在社会隔离和睡眠障碍的老年人发生认知功能障碍的风险为不存在社会隔离且不存在睡眠障碍老年人的11.811倍(95％CI:5.923～23.552),相对超危险度比(RERI)为8.167(95％CI:0.199～16.134),归因比(AP)为0.640(95％CI:0.379～0.902),交互作用指数(S)为3.276(95％CI:1.374～7.814)。结论社会隔离、睡眠质量是老年人认知功能障碍的危险因素,且二者对认知功能的影响具有相加交互作用。

Abstract: Objective To explore the effect of social isolation, sleep quality and their interaction on cognitive function in the elderly. Methods From October to December 2021, stratified sampling method was used to select 520 elderly people from Bengbu City. Lubben Social Network Scale, Pittsburgh Sleep Quality Index and Montreal Cognitive Assessment-Basic were used to evaluate the social isolation, sleep quality and cognitive function of the elderly, and Logistic regression analysis and interaction analysis were used to analyze the association among them. Results A total of 506 elderly were enrolled in the study finally. Among the 506 elderly, 166(32.8%) presented with social isolation, 138(27.3%) with sleep disorders, and 116(22.9%) with cognitive dysfunction. After adjusting age, education level, living status, marital status, and combined chronic diseases, the results of binary Logistic regression analysis showed that social isolation(OR=3.637, 95%CI:2.174-6.205) and sleep disorder(OR= 3.308, 95%CI:1.970-5.556) were the influencing factors of cognitive dysfunction in the elderly. The results of interaction analysis showed that the risk of cognitive impairment in the elderly with social isolation and sleep disorder was 11.811(95%CI:5.923-23.552) times higher than that in the elderly without social isolation and sleep disorder, with a relative excess risk due to interaction(RERI) of 8.167(95%CI:0.199-16.134), with an attributable proportion of interaction(AP)of 0.640(95%CI:0.379-0.902), with the synergy index(S) of 3.276(95%CI:1.374-7.814). Conclusions Social isolation and sleep quality are the risk factors of cognitive function in the elderly, and their effects on cognitive function have additive interaction.
