我们以 354 名年龄在 50 岁以上且基线时简易精神状态检查 (MMSE) 分数为 28 以上的成年人为样本，研究了社交网络特征与整体认知状态之间的关系。多变量分析表明，较大社交网络中的互动与更好地维持 MMSE 分数相关，并减少 12 年后随访时下降到基于人群的下四分位数 MMSE 分数的几率。在随访中，较高水平的人际活动（在较大的社交网络中更频繁的接触）和接触情感支持与 MMSE 独立呈正相关。研究结果表明，较大社交网络中的互动是预示认知能力下降较少的一个标志，并且不同的关联路径将人际活动和情感支持与认知功能联系起来。
We examined the relationship between social network characteristics and global cognitive status in a community-based sample of 354 adults aged 50+ and with Mini-Mental State Examination (MMSE) scores of 28+ at baseline. Multivariate analyses indicated that interaction in larger social networks related to better maintenance of MMSE scores and reduced odds of decline to population-based lower quartile MMSE scores at follow-up 12 years later. At follow-up, higher levels of interpersonal activity (more frequent contacts in larger social networks) and exposure to emotional support independently related positively to MMSE. The findings suggest that interaction in larger social networks is a marker that portends less cognitive decline, and that distinct associational paths link interpersonal activity and emotional support to cognitive function.
