Intact cognitive function is crucial for healthy aging. Functional social support is thought to protect against cognitive decline. We conducted a systematic review to investigate the association between functional social support and cognitive function in middle- and older-aged adults.
Articles were obtained from PubMed, PsycINFO, Sociological Abstracts, CINAHL, and Scopus. Eligible articles considered any form of functional social support and cognitive outcome. We narratively synthesized extracted data by following the Synthesis Without Meta-Analysis (SWiM) guidelines and assessed risk of bias using the Newcastle-Ottawa Scale (NOS).
Eighty-five articles with mostly low risk-of-bias were included in the review. In general, functional social support-particularly overall and emotional support-was associated with higher cognitive function in middle- and older-aged adults. However, these associations were not all statistically significant. Substantial heterogeneity existed in the types of exposures and outcomes evaluated in the articles, as well as in the specific tools used to measure exposures and outcomes.
Our review highlights the role of functional social support in the preservation of healthy cognition in aging populations. This finding underscores the importance of maintaining substantive social connections in middle and later life.

完整的认知功能对于健康老龄化至关重要。功能社会支持被认为可以预防认知能力下降。我们进行了一项系统评价，以调查中年和老年人群体中功能社会支持与认知功能之间的关系。
从 PubMed、PsycINFO、Sociological Abstracts、CINAHL 和 Scopus 中获取文章。符合条件的文章考虑了任何形式的功能社会支持和认知结果。我们按照无荟萃分析的综合方法（SWiM）指南对提取的数据进行叙述性综合，并使用纽卡斯尔-渥太华量表（NOS）评估偏倚风险。
共纳入 85 篇偏倚风险较低的文章。一般来说，功能社会支持——尤其是整体和情感支持——与中年和老年人群体的较高认知功能相关。然而，这些关联并非全部具有统计学意义。文章中评估的暴露和结果类型以及用于测量暴露和结果的特定工具存在很大的异质性。
我们的综述强调了功能社会支持在保护老年人群体健康认知方面的作用。这一发现强调了在中年和晚年保持实质性社会联系的重要性。
