Limited research is available on the relationship between social support, social strain, and cognitive function among community-dwelling U.S. Chinese older adults. This study aims to examine the associations between social support/strain and cognitive outcomes.
Data were drawn from the Population-Based Study of Chinese Elderly (N = 3,159). Cognitive function was measured by a battery of tests including the East Boston Memory Test, the Digit Span Backwards assessment, and the Symbol Digit Modalities Test. Social support and strain were measured by the scales drawn from the Health and Retirement study. Multiple regression analyses were conducted.
Social support was significantly associated with global cognitive function (β = .11, SE = .02, p < .001), episodic memory (β = .11, SE = .03, p < .001), working memory (β = .18, SE = .08, p < .05), and executive function (β = 1.44, SE = .37, p < .001). Social strain was significantly associated with global cognitive function (β = .23, SE = .05, p < .001), episodic memory (β = .27, SE = .07, p < .001), working memory (β = .34, SE = .17, p < .05), and executive function (β = 2.75, SE = .85, p < .01). In terms of sources of social support/strain, higher support from friends was significantly associated with higher global cognitive function (β = .04, SE = .02, p < .05), higher episodic memory (β = .05, SE = .02, p < .05), and higher executive function (β = .71, SE = .29, p < .05). Higher strain from spouse was significantly associated with higher global cognitive function (β = .10, SE = .03, p < .01), higher episodic memory (β = .11, SE = .04, p < .01), and higher executive function (β = 1.28, SE = .49, p < .01). Higher strain from friends was significantly associated with higher executive function (β = 3.59, SE = 1.17, p < .01).
Social support and strain were associated with cognitive outcomes. Future longitudinal studies should be conducted.
关于美国社区居住的华裔老年人的社会支持、社会压力与认知功能之间的关系，现有研究有限。本研究旨在探讨社会支持/压力与认知结果之间的关联。
数据取自基于人群的华裔老年人研究（N = 3159）。认知功能通过一系列测试进行测量，包括东波士顿记忆测试、数字广度倒背评估和符号数字模式测试。社会支持和压力通过从健康与退休研究中提取的量表进行测量。进行了多元回归分析。
社会支持与整体认知功能（β = 0.11，标准误 = 0.02，p < 0.001）、情景记忆（β = 0.11，标准误 = 0.03，p < 0.001）、工作记忆（β = 0.18，标准误 = 0.08，p < 0.05）和执行功能（β = 1.44，标准误 = 0.37，p < 0.001）显著相关。社会压力与整体认知功能（β = 0.23，标准误 = 0.05，p < 0.001）、情景记忆（β = 0.27，标准误 = 0.07，p < 0.001）、工作记忆（β = [0.34]，标准误 = 0.17，p < 0.05）和执行功能（β = 2.75，标准误 = 0.85，p < 0.01）显著相关。在社会支持/压力的来源方面，来自朋友的较高支持与较高的整体认知功能（β = 0.04，标准误 = 0.02，p < 0.05）、较高的情景记忆（β = 0.05，标准误 = 0.02，p < 0.05）和较高的执行功能（β = 0.71，标准误 = 0.29，p < 0.05）显著相关。来自配偶的较高压力与较高的整体认知功能（β = 0.10，标准误 = 0.03，p < 0.01）、较高的情景记忆（β = 0.11，标准误 = 0.04，p < 0.01）和较高的执行功能（β = 1.28，标准误 = 0.49，p < 0.01）显著相关。来自朋友的较高压力与较高的执行功能（β = 3.59，标准误 = 1.17，p < 0.01）显著相关。
社会支持和压力与认知结果相关。未来应进行纵向研究。
