研究黑人/非裔美国人（AA）和白人/欧洲裔美国人（EA）大学生在一年半时间内睡眠问题的变化，并考虑种族歧视在睡眠问题种族差异中的中介作用。一所以白人为主的大型大学的学生（N = 133, 41%男性，57%女性，平均年龄= 18.8，SD= 0.90）在基线和随访评估中报告了习惯性睡眠特征和种族歧视经历。从睡眠潜伏期、持续时间、效率和质量的报告中评估睡眠问题的潜在变量。纵向模型被用来检验睡眠问题随时间的种族差异以及感知歧视的中介作用。协变量包括年龄、性别、父母教育程度、父母收入、体重指数、自评身体健康和抑郁症状。每一项单独的睡眠测量也被单独检查，并使用睡眠问题测量的替代公式进行敏感性分析。asa比ea有更多的睡眠问题。随着时间的推移，感知到的歧视也与睡眠问题的增加有关，并介导了睡眠中的种族差异。当每个睡眠指标被单独考虑，并与其他睡眠问题测量方法保持一致时，这种发现模式是相似的。研究结果强调了大学期间睡眠的种族差异的重要性，并表明歧视的经历会导致群体差异。
To examine changes in sleep problems over a 1.5 year period among Black/African American (AA) and White/European American (EA) college students, and consider the role of racial discrimination as a mediator of race differences in sleep problems over time. Students attending a large, predominantly White university (N = 133, 41% AA, 57% female, Mean age= 18.8, SD=.90) reported on habitual sleep characteristics and experiences of racial discrimination at baseline and follow-up assessments. A latent variable for sleep problems was assessed from reports of sleep latency, duration, efficiency, and quality. Longitudinal models were used to examine race differences in sleep problems over time and the mediating role of perceived discrimination. Covariates included age, gender, parent education, parent income, body mass index, self-rated physical health, and depressive symptoms. Each of the individual sleep measures was also examined separately, and sensitivity analyses were conducted using alternative formulations of the sleep problems measure. AAs had greater increases in sleep problems than EAs. Perceived discrimination was also associated with increases in sleep problems over time, and mediated racial disparities in sleep. This pattern of findings was similar when each of the sleep indicators was considered separately, and held with alternative sleep problems measures. Findings highlight the importance of racial disparities in sleep across the college years and suggest that experiences of discrimination contribute to group disparities.
