To test the association between self-reported unfair treatment and objective and self-reported sleep characteristics in African American and Caucasian adults.
Cross-sectional study of 97 African American and 113 Caucasian middle-aged adults.
Participants completed: (a) two-night in-home, polysomnography (PSG) sleep study, (b) sleep diaries and actigraph assessments across 9 days and nights, and (c) self-report measures of sleep quality in the past month, and daytime sleepiness in the past 2 weeks.
Greater unfair treatment was associated with reports of poorer self-reported sleep quality and greater daytime sleepiness, shorter sleep duration, and lower sleep efficiency as measured by actigraphy and PSG, and a smaller proportion of rapid eye movement (REM) sleep. Racial/ethnic differences were few. Exploratory analyses showed that nightly worry partially mediated the associations of unfair treatment with sleep quality, daytime sleepiness, sleep efficiency (actigraphy), and proportion of REM sleep.
Perceptions of unfair treatment are associated with sleep disturbances in both African American and Caucasian adults. Future studies are needed to identify the pathways that account for the association between unfair treatment and sleep.
测试非裔美国人和白种人成年人中自我报告的不公平待遇与客观和自我报告的睡眠特征之间的关联。
对 97 名非裔美国人和 113 名白种中年成年人进行的横断面研究。
参与者完成了：(a) 两晚在家中的多导睡眠图 (PSG) 睡眠研究，(b) 9 天和 9 夜的睡眠日记和活动记录仪评估，以及 (c) 过去一个月的睡眠质量自我报告和过去 2 周的日间嗜睡自我报告。
不公平待遇程度与较差的自我报告睡眠质量和日间嗜睡、睡眠持续时间缩短以及活动记录仪和 PSG 测量的睡眠效率降低以及快速眼动 (REM) 睡眠比例较低相关。种族/民族差异很少。探索性分析表明，每晚的担忧部分中介了不公平待遇与睡眠质量、日间嗜睡、睡眠效率（活动记录仪）和 REM 睡眠比例之间的关联。
非裔美国人和白种成年人中自我报告的不公平待遇与睡眠障碍有关。需要进一步的研究来确定解释不公平待遇与睡眠之间关联的途径。
