Abstract

Objectives: Research suggests that chronic stress reduces cognitive functioning; however, studies examining this relationship for race-related stress, such as racial discrimination, are limited and primarily focus on older adults. Moreover, considering the importance of sleep when coping with stress, it is possible that sleep buffers the effect of racial discrimination on cognitive functioning. The present study examined the role of sleep duration and quality in the relationship between racial discrimination and cognitive functioning in early adolescence.

Method: This study utilized a sample of racial and ethnic minority adolescents (N = 176; M_age = 12.1 years; 55% females; 76% Black/African American, 15% Hispanic/Latino, and 8% other minority) participating in a school-based study of adolescent mental health and academic functioning. Analyses included a single multivariate regression model predicting inhibitory control and episodic memory from racial discrimination, sleep duration, sleep quality (objective and subjective), and the interactions between racial discrimination and each sleep variable.

Results: Controlling for age, sex, race/ethnicity, and annual household income, results from the multivariate regression revealed a significant interaction between racial discrimination and sleep duration in predicting inhibitory control. Follow-up analyses showed that racial discrimination was associated with poorer inhibitory control in youth who experienced short sleep duration.

种族歧视和睡眠对少数民族青少年认知功能的影响。

研究目的研究表明，长期压力会降低认知功能；然而，针对与种族有关的压力（如种族歧视）进行的研究却很有限，而且主要集中在老年人身上。此外，考虑到睡眠在应对压力时的重要性，睡眠有可能缓冲种族歧视对认知功能的影响。本研究探讨了睡眠时间和质量在青少年早期种族歧视与认知功能之间关系中的作用：本研究使用了一个少数民族青少年样本（人数=176；年龄=12.1岁；55%为女性；76%为黑人/非洲裔美国人，15%为西班牙裔/拉丁美洲裔美国人，8%为其他少数民族），该样本参与了一项以学校为基础的青少年心理健康和学业功能研究。分析包括一个单一的多变量回归模型，通过种族歧视、睡眠时间、睡眠质量（客观和主观）以及种族歧视与每个睡眠变量之间的交互作用来预测抑制控制和外显记忆：结果：在控制年龄、性别、种族/民族和家庭年收入的情况下，多元回归结果显示，种族歧视和睡眠时间在预测抑制控制能力方面存在显著的交互作用。后续分析表明，在睡眠时间较短的青少年中，种族歧视与较差的抑制控制能力有关：结论：睡眠时间短可能会增加歧视对青少年认知功能的有害影响。(PsycInfo Database Record (c) 2024 APA, 版权所有）。
