This study examines the association between a modifiable psychosocial factor, social support availability (SSA), and the memory domain of cognitive function in persons aged 45-85 years.
We used baseline data from the Canadian Longitudinal Study on Aging (CLSA) (n = 21,241) to conduct multiple linear regression analyses of the association between SSA (overall and four subscales) and memory. The CLSA assessed immediate and delayed recall memory using the Rey Auditory Verbal Learning Test (RAVLT).
Higher levels of each type of SSA were positively associated with better performance on both immediate and delayed recall memory. The largest associations (β coefficients [95% confidence intervals]) for z-score differences on the RAVLT were observed for overall SSA (immediate: 0.07 [0.04-0.10]; delayed recall: 0.06 [0.02-0.09]) and the emotional/informational subscale (immediate: 0.06 [0.03-0.09]; delayed recall: 0.05 [0.02-0.08]).
SSA is modifiable and positively associated with memory. Public health initiatives to provide support resources such as material aid, emotional support, or companionship may entail positive benefits for memory. Promotion of SSA is also important for policies encouraging early diagnosis and intervention in dementia.
本研究探讨了一种可改变的心理社会因素，即社会支持可用性（SSA），与 45-85 岁人群认知功能的记忆领域之间的关系。
我们使用加拿大老龄化纵向研究（CLSA）（n=21,241）的基线数据，对 SSA（总体和四个亚量表）与记忆之间的关系进行了多元线性回归分析。CLSA 使用 Rey 听觉言语学习测试（RAVLT）评估即时和延迟回忆记忆。
每种类型的 SSA 水平越高，即时和延迟回忆记忆的表现越好。RAVLT 上 z 分数差异的最大关联（β系数[95%置信区间]）为 SSA 总体（即时：0.07[0.04-0.10]；延迟回忆：0.06[0.02-0.09]）和情感/信息亚量表（即时：0.06[0.03-0.09]；延迟回忆：0.05[0.02-0.08]）。
SSA 是可改变的，与记忆呈正相关。提供物质援助、情感支持或陪伴等支持资源的公共卫生举措可能会对记忆产生积极影响。促进 SSA 对于鼓励痴呆症早期诊断和干预的政策也很重要。
