Background

Perceived racial/ethnic discrimination and poor sleep occur across all races/ethnicities in the U.S., though both are most common among racial/ethnic minorities. Few studies have investigated associations between perceived racial/ethnic discrimination and various sleep dimensions in a multiethnic population.

Methods

We analyzed cross-sectional associations among 40,038 eligible Sister Study participants (enrollment: 2003-2009) who reported ever/never experiencing specific types of everyday (e.g., treated unfairly at a store or restaurant) or major (e.g., unfairly stopped, threatened, or searched by police) discrimination attributed to their race/ethnicity during a follow-up survey in 2008-2012. Participants also reported short sleep duration (<7 hours), sleep debt (≥2-hour difference between longest and shortest sleep duration), frequent napping (≥3 times/week), and insomnia. Poisson regression with robust variance estimation, adjusted for sociodemographic and health characteristics, estimated prevalence ratios (PRs) and 95% confidence intervals (CIs) for the association between each type of racial/ethnic discrimination and each sleep dimension, overall and by race/ethnicity.

Results

Mean age was 55 ± 8.9 years, 89% were NH-white, 8% NH-black, and 3% Hispanic/Latina. NH-black participants were the most likely to report everyday (76% vs. 4% [NH-whites] and 36% [Hispanics/Latinas]) and major racial/ethnic discrimination (52% vs. 2% [NH-whites] and 18% [Hispanics/Latinas]). Participants who experienced both types versus neither were more likely to report short sleep duration (PR=1.17 [95% CI: 1.09-1.25]) and insomnia symptoms (PR=1.10 [1.01-1.20]) but not other poor sleep dimensions.

Conclusions

Racial/ethnic minority women were most likely to experience racial/ethnic discrimination, which was associated with certain poor sleep dimensions among women of all races/ethnicities.

美国妇女的多种族人口的日常和种族/种族歧视和睡眠健康的主要经验：姐妹研究的发现。

背景

尽管在种族/族裔少数群体中这两种情况最普遍，但在美国所有种族/族裔中都存在感知到的种族/族裔歧视和睡眠不足的现象。很少有研究调查多种族人群中感知到的种族/种族歧视与各种睡眠维度之间的关联。

方法

We analyzed cross-sectional associations among 40,038 eligible Sister Study participants (enrollment: 2003-2009) who reported ever/never experiencing specific types of everyday (e.g., treated unfairly at a store or restaurant) or major (e.g., unfairly stopped, threatened, or searched by police) discrimination attributed to their race/ethnicity during a follow-up survey in 2008-2012. Participants also reported short sleep duration (<7 hours), sleep debt (≥2-hour difference between longest and shortest sleep duration), frequent napping (≥3 times/week), and insomnia. Poisson regression with robust variance estimation, adjusted for sociodemographic and health characteristics, estimated prevalence ratios (PRs) and 95% confidence intervals (CIs) for the association between each type of racial/ethnic discrimination and each sleep dimension, overall and by race/ethnicity.

结果

平均年龄为55±8.9岁，NH-白人为89％，NH-黑人为8％，西班牙裔/拉丁裔为3％。黑人黑人参与者最有可能每天举报（76％vs. 4％[NH-whites]和36％[Hispanics / Latinas]）和主要的种族/族裔歧视（52％vs. 2％[NH-whites]和18％[西班牙裔/拉丁裔]）。既有两种类型又没有两种类型的参与者更有可能报告睡眠时间短（PR = 1.17 [95％CI：1.09-1.25]）和失眠症状（PR = 1.10 [1.01-1.20]），但其他睡眠质量较差的人。

结论

种族/少数族裔妇女最有可能遭受种族/族裔歧视，这与各种族/族裔妇女的某些睡眠不足有关。
