尽管认知功能与衰老过程中大脑的生物学变化密切相关，但人们对东西方社会文化差异的作用知之甚少。在长达8年的英国和中国的随访中，我们研究了个体社会经济指标（如教育、家庭财富）和背景水平特征（如城市化）与记忆表现和记忆衰退之间的关系。分析样本包括来自英国老龄化纵向研究（n = 6,687）和中国健康与退休纵向研究（n = 10,252）的50岁以上参与者。采用混合线性模型来检验基线个人社会经济指标（教育、财富）和背景水平特征（城市化）对记忆随时间变化的关系。我们的分析表明，在英国和中国，高等教育和财富与更好的基线记忆有关。尽管如此，背景层面的特征（如城市化）的影响在两国之间有所不同。对于英国人来说，生活在农村地区的人在记忆方面表现出优势，而在中国则相反。在中国，记忆力下降似乎与高等教育、财富和城市化有关，而在英国则不然。我们的研究结果强调了英国和中国在记忆表现上的重大社会经济和环境不平等，以及主要在中国的记忆力下降速度。预防记忆衰退的公共卫生战略应针对个人和环境层面的社会经济差距，以保护那些特别弱势的人。
Although cognitive functioning is strongly associated with biological changes in the brain during the aging process, very little is known about the role of sociocultural differentials between the western and eastern parts of the world. We examined the associations between individual socioeconomic markers (e.g., education, household wealth) and contextual levels characteristics (e.g., urbanicity) with memory performance and memory decline over up to 8 years of follow-up in England and China. The analytical samples included participants aged 50+ from the English Longitudinal Study of Aging (n = 6,687) and the China Health and Retirement Longitudinal Study (n = 10,252). Mixed linear models were employed to examine the association between baseline individual socioeconomic markers (education, wealth) and contextual-level characteristics (urbanicity) on the change in memory over time. Our analyses showed that higher education and wealth were associated with better baseline memory in both England and China. Still, the impact of contextual-level characteristics such as urbanicity differed between the 2 countries. For English individuals, living in a rural area showed an advantage in memory, while the opposite pattern was observed in China. Memory decline appeared to be socioeconomically patterned by higher education, wealth, and urbanicity in China but not in England. Our findings highlight substantial socioeconomic and contextual inequity in memory performance in both England and China, as well as in the rate of memory decline primarily in China. Public health strategies for preventing memory decline should target the socioeconomic gaps at the individual and contextual levels to protect those particularly disadvantaged.
