家庭拥有的影响日常生活条件的物质资源可能对衰老过程中的认知健康很重要，尤其是在低收入环境中，但关于这一主题的证据很少。我们在南非农村一项具有人口代表性的研究中，调查了家庭物质资源的长期趋势与老年人认知功能之间的关系。数据来自2014/2015年“非洲健康与老龄化：南非一个深入社区的纵向研究”（HAALSI）中对4580名40岁及以上成年人的基线访谈，这些数据与2001年至2013年阿金库尔健康和社会人口监测系统（HDSS）中关于他们家庭物质资源的回顾性记录相关联。阿金库尔HDSS每两年使用一个五点指数对家庭物质资源进行评估，该指数涵盖居住材料、水和卫生设施、电力来源、牲畜和技术设施。在HAALSI中对认知功能进行了评估，并作为一个z标准化的潜在变量进行分析，该变量涵盖时间定向、情景记忆和计算能力。我们评估了平均资源指数得分的五分位数、资源指数得分的波动性以及资源指数得分的变化与随后的认知功能之间的关系，包括总体关系以及按资源类型的关系。较高的家庭平均资源与认知功能呈正相关（平均资源指数得分最高五分位数与最低五分位数相比，β调整后 = 0.237标准差[SD]单位；95%置信区间：0.163 - 0.312；p趋势<0.0001），家庭资源随时间的较大改善也是如此（资源变化最高五分位数与最低五分位数相比，β调整后 = 0.122 SD单位；95%置信区间：0.040 - 0.205；p趋势 = 0.001）。结果在通过年龄评估异质性以及仅限于受过正规教育的人群的敏感性分析中是稳健的。这些发现主要由包括冰箱、炉灶、电话、电视和车辆在内的技术设施所驱动。这些设施可能通过改善营养以及通过交通和家庭外的社会接触提供认知刺激的机会来支持认知功能。

我们发现家庭物质资源可能在衰老过程中支持认知健康。
随着时间推移资源的更大改善与更好的认知能力相关。
结果由用于烹饪、交通和通信的资源所驱动。
未来的研究应该研究家庭资源如何促进认知健康。
Material resources owned by households that affect daily living conditions may be salient for cognitive health during aging, especially in low-income settings, but there is scarce evidence on this topic. We investigated relationships between long-term trends in household material resources and cognitive function among older adults in a population-representative study in rural South Africa. Data were from baseline interviews with 4580 adults aged ≥40 in “Health and Ageing in Africa: A Longitudinal Study of an INDEPTH Community in South Africa” (HAALSI) in 2014/2015 linked to retrospective records on their household material resources from the Agincourt Health and Socio-Demographic Surveillance System (HDSS) from 2001 to 2013. Household material resources were assessed biennially in the Agincourt HDSS using a five-point index that captured dwelling materials, water and sanitation, sources of power, livestock, and technological amenities. Cognitive function was assessed in HAALSI and analyzed as a z-standardized latent variable capturing time orientation, episodic memory, and numeracy. We evaluated the relationships between quintiles of each of the mean resource index score, volatility in resource index score, and change in resource index score and subsequent cognitive function, overall and by resource type. Higher mean household resources were positively associated with cognitive function (βadj = 0.237 standard deviation [SD] units for the highest vs. lowest quintile of mean resource index score; 95% CI: 0.163–0.312; p-trend<0.0001), as were larger improvements over time in household resources (βadj = 0.122 SD units for the highest vs. lowest quintile of change in resources; 95% CI: 0.040–0.205; p-trend = 0.001). Results were robust to sensitivity analyses assessing heterogeneity by age and restricting to those with formal education. The findings were largely driven by technological amenities including refrigerators, stoves, telephones, televisions, and vehicles. These amenities may support cognitive function through improving nutrition and providing opportunities for cognitive stimulation through transportation and social contact outside of the home. Data were from a population-based longitudinal study of aging in rural South Africa. We found that household material resources may support cognitive health during aging. Greater improvements in resources over time were associated with better cognition. Results were driven by resources for cooking, transportation, and communication. Future research should study how household resources may promote cognitive health.
