Research on associations between early life adversity (ELA) and later life cognition has yielded mixed results and generally have not considered how broader societal systems of stratification potentially influence associations. The current study addresses this gap by exploring if racialized identity and childhood socioeconomic status (cSES) moderate associations between ELA exposure and later life cognition.
Using data from the Health and Retirement Study (Waves 2010-2018), we used growth curve modeling to examine if the confluence of ELA, cSES, and racialized identity is associated with cognition.
Among White participants, greater exposure to ELA was associated with poorer baseline cognitive functioning, and higher cSES buffered against this association. Among Black participants, exposure to ELA was not associated with baseline cognitive functioning, regardless of cSES. We did not find evidence of any associations between main predictors nor their interactions with change in cognition over time.
This study provides evidence that associations between ELA and later life cognition is contingent upon multiple social positions in the United States. These findings support the importance of integrating insights on intersecting social positions within life-course-oriented efforts to reduce racialized cognitive disparities.
关于早年逆境(ELA)与晚年认知之间关联的研究结果不一,且总体上未考虑更广泛的社会分层系统如何潜在地影响这种关联。本研究通过探讨种族化身份和童年社会经济地位(cSES)是否调节ELA暴露与晚年认知之间的关联来填补这一空白。
利用健康与退休研究(2010 - 2018年各波次)的数据,我们使用增长曲线模型来检验ELA、cSES和种族化身份的融合是否与认知相关。
在白人参与者中,更多地暴露于ELA与较差的基线认知功能相关,而较高的cSES缓冲了这种关联。在黑人参与者中,无论cSES如何,暴露于ELA与基线认知功能均无关联。我们没有发现主要预测因素之间及其与认知随时间变化的交互作用存在任何关联的证据。
本研究提供了证据表明,ELA与晚年认知之间的关联取决于美国的多种社会地位。这些发现支持了在以生命历程为导向的努力中整合关于交叉社会地位的见解对于减少种族化认知差距的重要性。
