Low neighborhood-level socioeconomic status has been associated with poorer health, reduced physical activity, increased psychological stress, and less neighborhood-based social support. These outcomes are correlates of late life cognition, but few studies have specifically investigated the neighborhood as a unique source of explanatory variance in cognitive aging. This study supplemented baseline cognitive data from the ACTIVE (Advanced Cognitive Training for Independent and Vital Elderly) study with neighborhood-level data to investigate (1) whether neighborhood socioeconomic position (SEP) predicts cognitive level, and if so, whether it differentially predicts performance in general and specific domains of cognition and (2) whether neighborhood SEP predicts differences in response to short-term cognitive intervention for memory, reasoning, or processing speed. Neighborhood SEP positively predicted vocabulary, but did not predict other general or specific measures of cognitive level, and did not predict individual differences in response to cognitive intervention.
社区层面较低的社会经济地位与较差的健康状况、较少的身体活动、增加的心理压力以及较少的社区社会支持相关。这些结果与晚年认知相关,但很少有研究专门调查社区作为认知老化解释差异的独特来源。本研究用社区层面的数据补充了ACTIVE(针对独立和活力老年人的高级认知训练)研究的基线认知数据,以调查:(1)社区社会经济地位(SEP)是否能预测认知水平,如果可以,它是否能在认知的一般和特定领域中差异预测表现;(2)社区SEP是否能预测对记忆、推理或处理速度的短期认知干预的反应差异。社区SEP能正向预测词汇量,但不能预测认知水平的其他一般或特定指标,也不能预测对认知干预反应的个体差异。
