To examine the association between social isolation and cognitive function among the elderly living in the communities of Daqing city. A total of 981 community residents aged 60 years or over, were surveyed with a questionnaire. Both Lubben Social Network Scale-6 (LSNS-6) and Montreal Congnitive Assessment (MoCA) Changsha Versions were used to respectively screen the status of social isolation and cognitive function, on these elderly. The average age was 71 years old for the 981 study participants. 10.60 (104/981) of the participants were assessed as having the status of social isolation, 9.48 (93/981) as having marginal family ties and 13.97 (137/981) as having marginal friendship ties. Results from the multivariate linear regression analysis revealed that participants with higher scores of LSNS-6 presenting better cognitive function score, with a partial regression coefficient as 0.10 (<0.01). The MoCA scores in participants with social isolation (20.38±5.54) were significantly lower than the ones without social isolation (22.10±5.01) and the difference was statistically significant (<0.01). Social isolation was significantly related to the domain scores on visuo-spatial constructional executive functions (=0.02), naming (=0.03), language (=0.01) and delayed memory functions (<0.01), but not with other domains as concentration (=0.33), orientation (=0.27) or abstraction (=0.49). The findings suggested that social isolation was mainly caused by the lack of friendship ties and associated with cognitive function and among the elderly in Daqing city, Heilongjiang province.
为研究大庆市社区老年人社会隔离与认知功能之间的关联。共对981名60岁及以上的社区居民进行问卷调查。采用鲁本社会网络量表-6（LSNS-6）和蒙特利尔认知评估量表（MoCA）长沙版分别筛查这些老年人的社会隔离状况和认知功能。981名研究参与者的平均年龄为71岁。10.60%（104/981）的参与者被评估为处于社会隔离状态，9.48%（93/981）为家庭关系边缘，13.97%（137/981）为朋友关系边缘。多元线性回归分析结果显示，LSNS-6得分较高的参与者认知功能得分更好，偏回归系数为0.10（<0.01）。社会隔离参与者的MoCA得分（20.38±5.54）显著低于无社会隔离者（22.10±5.01），差异具有统计学意义（<0.01）。社会隔离与视觉空间结构执行功能（=0.02）、命名（=0.03）、语言（=0.01）和延迟记忆功能（<0.01）领域得分显著相关，但与注意力（=0.33）、定向（=0.27）或抽象能力（=0.49）等其他领域无关。研究结果表明，在黑龙江省大庆市的老年人中，社会隔离主要由缺乏朋友关系引起，并与认知功能相关。
