Perceived discrimination is a potential cause of racial and ethnic disparities in health. Disturbed sleep may serve as a mechanism linking perceived racism with health consequences. This study investigates data from 7,148 adults from Michigan and Wisconsin who participated in the 2006 Behavioral Risk Factor Surveillance System. Hierarchical logistic regression analyses explored associations between perceived racial discrimination and self-reported sleep disturbance and daytime fatigue. Sleep disturbance and daytime fatigue were reported in 19% and 21% of the sample, respectively. Black/African American respondents (21%) report perceiving worse experiences, compared to people of other races, when seeking health care at higher rates than non-Hispanic White respondents (3%). Results from logistic regression models show that perceived racial discrimination is associated with increased risks of sleep disturbance (odds ratio [OR] = 2.62, p < .0001) and daytime fatigue (OR = 2.07, p < .0001). After adjustment for all covariates, perceived discrimination remains a significant predictor of sleep disturbance (OR = 1.60, p = .04). The interaction between perceived racism and race (Black/African American vs. non-Hispanic White) was nonsignificant. This population-based research adds to the growing body of data, suggesting that perceived racism may impact health via its influence on sleep-wake behaviors.
感知歧视是健康方面的种族和民族差异的一个潜在原因。睡眠障碍可能是将感知到的种族主义与健康后果联系起来的一种机制。本研究调查了来自密歇根州和威斯康星州的 7148 名成年人的数据，他们参加了 2006 年的行为风险因素监测系统。分层逻辑回归分析探讨了感知到的种族歧视与自我报告的睡眠障碍和白天疲劳之间的关联。分别有 19%和 21%的样本报告了睡眠障碍和白天疲劳。与其他种族的人相比，黑人/非裔美国人（21%）在寻求医疗保健时报告的经历更差，这一比例高于非西班牙裔白人（3%）。逻辑回归模型的结果表明，感知到的种族歧视与睡眠障碍（优势比[OR] = 2.62，p<.0001）和白天疲劳（OR = 2.07，p<.0001）的风险增加有关。在调整了所有协变量后，感知歧视仍然是睡眠障碍（OR = 1.60，p =.04）的一个重要预测因素。感知到的种族主义和种族（黑人/非裔美国人与非西班牙裔白人）之间的相互作用不显著。这项基于人群的研究增加了越来越多的数据，表明感知到的种族主义可能通过对睡眠-觉醒行为的影响来影响健康。
