Individual and environmental factors have been found to be related to cognitive function. However, few studies have examined the longitudinal effects of both individual and environmental factors over time. The purpose of this study was to examine the effects of individual and environmental factors over time on older people's cognitive function.
Nationally representative panel data from the Taiwan Longitudinal Survey on Aging 1999-2015 (n = 6349 persons, observations = 12,042) were used. City-level indicator data were sourced from the government. A multilevel mixed linear model analysis was conducted.
Better cognitive function was significantly related to individuals' work, ethnicity, younger age, higher education level, better self-rated health, higher level of emotional support received, being more religious, higher economic satisfaction, and living in the cities with higher population densities. Education and social connectedness were protective factors over time.
Socioeconomics and social connectedness are related to cognitive function. A more social integrated lifestyle and financially secure living is suggested in the policy.
个体因素和环境因素被发现与认知功能有关。然而，很少有研究同时考察个体和环境因素随时间的纵向影响。本研究旨在探讨个体和环境因素随时间对老年人认知功能的影响。
使用了来自台湾 1999-2015 年老龄化纵向调查的全国代表性面板数据（n=6349 人，观察数=12042）。城市层面的指标数据来自政府。采用多层次混合线性模型分析。
更好的认知功能与个体的工作、种族、年龄较小、教育程度较高、自我评估健康状况较好、获得更高水平的情感支持、更宗教信仰、经济满意度更高以及生活在人口密度更高的城市显著相关。教育和社会联系是随着时间推移的保护因素。
社会经济学和社会联系与认知功能有关。建议在政策中倡导更具社会融合性的生活方式和经济保障的生活。
