本研究建立在最近的发现基础上，表明制度和人际种族主义的压力可能导致非裔美国人患痴呆症的风险增加。我们调查了种族主义的两个后果-低社会经济地位(SES)和歧视-在多大程度上预测19年后自我报告的认知能力下降(SCD)。此外，我们还研究了可能将SES和歧视与认知能力下降联系起来的潜在中介途径。潜在的中介因素包括抑郁、加速的生物衰老和慢性病的发病。采用日常认知量表评定SCD。结构方程模型被用来评估2002年测量的社会经济地位和种族歧视对2021年报告的SCD的影响。在中介方面，2002年评估了中年抑郁症，2019年评估了加速老龄化，2019年评估了慢性病。将年龄和先证性抑郁作为协变量。结果SES和歧视对SCD有直接影响。此外，这两种应激源通过抑郁对SCD有显著的间接影响。最后，有证据表明，在更复杂的途径中，SES和歧视加速了生物衰老，加速了衰老，进而导致了慢性疾病，进而预测了SCD。讨论本研究的结果补充了越来越多的文献，表明生活在种族主义社会是解释美国黑人患痴呆症高风险的中心因素。未来的研究应该继续强调在生活过程中暴露于种族主义对认知的各种影响方式。
ObjectivesThe present study builds on recent findings suggesting that the stress of institutional and interpersonal racism may contribute to African Americans’ elevated risk for dementia. We investigated the extent to which 2 consequences of racism—low socioeconomic status (SES) and discrimination—predict self-reported cognitive decline (SCD) 19 years later. Further, we examined potential mediating pathways that might link SES and discrimination to cognitive decline. Potential mediators included depression, accelerated biological aging, and onset of chronic illnesses.MethodsHypotheses were tested using a sample of 293 African American women. SCD was assessed using the Everyday Cognition Scale. Structural equation modeling was used to assess the effects of SES and racial discrimination, both measured in 2002, on SCD reported in 2021. Turning to the mediators, midlife depression was assessed in 2002, accelerated aging in 2019, and chronic illness in 2019. Age and prodrome depression were included as covariates.ResultsThere were direct effects of SES and discrimination on SCD. In addition, these 2 stressors showed a significant indirect effect on SCD through depression. Finally, there was evidence for a more complex pathway where SES and discrimination accelerate biological aging, with accelerated aging, in turn leading to chronic illness, which then predicted SCD.DiscussionResults of the present study add to a growing literature indicating that living in a racialized society is a central factor in explaining the high risk for dementia among Black Americans. Future research should continue to emphasize the various ways that exposure to racism over the life course effects cognition.
