Introduction: We investigated the mediating role of leisure activity engagement as marker of cognitive reserve in the relation between neighborhood socio-economic position (SEP) and cognitive decline over 6 years. Methods: The study analyzed longitudinal data from 897 older adults who participated in the two waves (2011 and 2017) of the Vivre-Leben-Vivere (VLV) survey in Switzerland (M = 74.33 years in the first wave). Trail Making Test parts A and B were administered in both waves. Leisure activity engagement was assessed during interviews. Neighborhood SEP was derived from the Swiss Neighborhood Index of Socio-Economic Position (Swiss-SEP), provided by the Swiss National Cohort (SNC). Results: Latent change score modeling revealed that 42.5% of the relationship between higher neighborhood SEP and smaller cognitive decline was mediated via a higher frequency of leisure activities in the first wave. Conclusion: Neighborhood SEP constitutes an important contextual factor potentially influencing the pathways of cognitive reserve accumulation and, therefore, should be taken into account to better understand their effects on cognitive decline in old age.

认知储备介导邻里社会经济地位与认知衰退之间的关系

简介：我们调查了休闲活动参与作为认知储备标志物在社区社会经济地位 (SEP) 与认知能力下降之间的关系中的中介作用，超过 6 年。方法：该研究分析了参与瑞士 Vivre-Leben-Vivere (VLV) 调查的两波（2011 年和 2017 年）的 897 名老年人的纵向数据（第一波M = 74.33 岁）。Trail Making Test A 和 B 部分在两波中进行。在访谈期间评估休闲活动参与度。邻里 SEP 源自瑞士国家队列 (SNC) 提供的瑞士邻里社会经济地位指数 (Swiss-SEP)。结果：潜在变化评分模型显示，较高的社区 SEP 和较小的认知衰退之间的关系有 42.5% 是通过第一波中较高频率的休闲活动来调节的。结论：邻里 SEP 构成了一个重要的背景因素，可能影响认知储备积累的途径，因此，应该考虑到它们对老年认知衰退的影响。
