在以前的一项研究中，研究表明，社区社会经济劣势与拉丁美洲人的认知能力下降有关。没有研究探讨个人层面的社会经济因素是否以及在多大程度上解释了邻里劣势和认知能力下降之间的关系。本研究的目的是评估社区社会经济地位（SEP）对认知能力下降的影响，并研究个人层面的SEP因素（教育水平，年收入和职业）如何影响社区协会在10年的过程中。参与者（n = 1，789）是来自萨克拉门托地区拉丁裔老龄化研究的社区居住的墨西哥裔美国人。邻里SEP是通过将参与者的个人数据与2000年十年一次的人口普查联系起来得出的。作者使用改良简易精神状态检查评估认知功能。分析使用3级分层线性混合模型的时间内的个人在社区内。在调整了个体水平的社会人口学特征后，较高的邻居SEP与认知功能（β = -0.033; P < 0.05）和下降率（β = -0.0009; P < 0.10）显著相关。在调整个人教育水平后，邻居SEP仍然与基线认知相关，但与下降率无关。个人教育水平的差异解释了大部分的内部和邻里间的方差。这些结果表明，社区SEP对拉丁美洲人认知能力下降的影响主要是由教育引起的。
In 1 previous study, it was shown that neighborhood socioeconomic disadvantage is associated with cognitive decline among Latinos. No studies have explored whether and to what extent individual-level socioeconomic factors account for the relation between neighborhood disadvantage and cognitive decline. The purpose of the present study was to assess the influence of neighborhood socioeconomic position (SEP) on cognitive decline and examine how individual-level SEP factors (educational level, annual income, and occupation) influenced neighborhood associations over the course of 10 years. Participants (n = 1,789) were community-dwelling older Mexican Americans from the Sacramento Area Latino Study on Aging. Neighborhood SEP was derived by linking the participant's individual data to the 2000 decennial census. The authors assessed cognitive function with the Modified Mini-Mental State Examination. Analyses used 3-level hierarchical linear mixed models of time within individuals within neighborhoods. After adjustment for individual-level sociodemographic characteristics, higher neighborhood SEP was significantly associated with cognitive function (beta = -0.033; P < 0.05) and rates of decline (beta = -0.0009; P < 0.10). After adjustment for individual educational level, neighborhood SEP remained associated with baseline cognition but not with rates of decline. Differences in individual educational levels explained most of the intra- and interneighborhood variance. These results suggest that the effect of neighborhood SEP on cognitive decline among Latinos is primarily accounted for by education.
