Studies have shown the positive impact of perceived social support on cognitive function among older adults in rural areas. However, existing studies often overlook the impact of different support sources. This study aimed to explore the relationship between the diverse sources of perceived social support and cognitive function.
Participants were drawn from the Guizhou Rural Older Adults' Health Study (HSRO) in China. We included 791 participants who participated in a baseline survey in 2019 and a 3-year follow-up survey. Perceived social support was investigated from the six main sources (friend, relative, children, spouse, sibling, and neighbor). Hierarchical linear regression models were used to observe the effects of diverse sources of perceived social support and their combinations on cognitive function.
Cognitive function was positively associated with perceived support from children, friends, and neighbors. A positive association was found between cognitive function and increases in each additional source [ = 0.75 (95%CI: 0.51, 0.98), < 0.001]. Older adults who perceived support from both children and friends showed better cognitive function [ = 2.53 (95%CI: 1.35, 3.72), < 0.001]. The perception of support from spouse, siblings, and relatives did not show a statistically significant association with cognitive function among older adults in rural areas.
This study found that the association between different sources of perceived social support and cognitive function was varied. This study provides scientific evidence that personalized support strategies may benefit in promoting cognitive health in rural older adults.
研究表明，感知到的社会支持对农村老年人的认知功能有积极影响。然而，现有研究往往忽视了不同支持来源的影响。本研究旨在探讨感知到的社会支持的不同来源与认知功能之间的关系。
参与者来自中国贵州农村老年人健康研究（HSRO）。我们纳入了791名在2019年参加基线调查并进行了为期3年随访调查的参与者。从六个主要来源（朋友、亲戚、子女、配偶、兄弟姐妹和邻居）调查感知到的社会支持。使用分层线性回归模型观察感知到的社会支持的不同来源及其组合对认知功能的影响。
认知功能与来自子女、朋友和邻居的感知支持呈正相关。发现认知功能与每增加一个支持来源之间存在正相关[β = 0.75（95%CI：0.51，0.98），P < 0.001]。同时感知到来自子女和朋友支持的老年人表现出更好的认知功能[β = 2.53（95%CI：1.35，3.72），P < 0.001]。在农村老年人中，配偶、兄弟姐妹和亲戚的支持感知与认知功能之间未显示出统计学上的显著关联。
本研究发现，感知到的社会支持的不同来源与认知功能之间的关联各不相同。本研究提供了科学证据，表明个性化支持策略可能有助于促进农村老年人的认知健康。
