Social-Environmental Predictors of Sleep Disparities During the Transition toCollege

项目摘要 少数民族/种族（ERM）更有可能遭受睡眠时间短和睡眠质量差的困扰 相对于白人。社会人口和环境压力因素不成比例地影响着ERMs， 与种族相关的睡眠差异的发展和维持有关。过渡到大学 是研究睡眠的一个特别重要的时间，因为年轻人会遇到一种独特的结构， 与睡眠有关的社会人口和环境压力。不再被束缚在早期的高中开始 与此同时，大学生报告说，他们的就寝时间更晚，也更不规律。大学生也睡得越来越少 比成年人差，这表明在年轻人中睡眠障碍的发展高峰。 针对两个睡眠弱势群体- ERMs和大学生-这项为期5年的纵向研究 调查了种族相关的睡眠差异在不同样本的大学生期间和之后， 过渡到大学;以及种族相关的睡眠差异如何预测下游健康和学术 通过学生的高年级的成果。该研究还调查了以下因素的风险和保护作用： 在此期间，族裔/种族身份是一个动态和不断变化的调节因素。 每日日记和睡眠活动记录的创新和新颖的组合，每两年一次的调查， 炎症生物标志物、端粒长度和人体测量的评估提供了一个无与伦比的 有机会调查日常和长期的机制，途径，和种族相关的后果， ERM和白色大学生大样本睡眠差异。这项研究的一个关键创新是， ERM、社会经济、第一代大学、居民和通勤者多样性的交叉包容。的 本研究的三个具体目标由强有力的初步数据（R21 MD 011388），科学前提， 以及基于种族的压力和睡眠差异模型。拟议的研究： 1.确定社会人口和环境压力对种族的日常和长期影响- 大学过渡期间和未来四年的相关睡眠差异（持续时间，质量，规律性） 2.与种族相关的睡眠差异作为社会人口统计学和 环境压力影响健康、学术和生理生物标志物（炎症和端粒 结果 3.调查种族/种族身份作为压力对人的日常和长期影响的动态调节剂。 睡眠和睡眠的结果 这些目标共同推动了发展和健康公平科学，调查社会人口学如何 和环境压力导致不同大学生之间与种族有关的睡眠差异， 预测每日和长期的健康和学术随着时间的推移。

Project Summary Ethnic/racial minorities (ERMs) are more likely to suffer from short sleep duration and poor sleep quality relative to Whites. Sociodemographic and environmental stressors disproportionately impact ERMs and have been implicated in the development and maintenance of race-related sleep disparities. The transition to college is an especially important time to investigate sleep since young adults encounter a unique configuration of sociodemographic and environmental stressors linked to sleep. No longer tethered to early high school start times, college students report later and more irregular bedtimes. College students also sleep less and more poorly than adults, suggesting a developmental peak in sleep disturbances among young adults. Focusing on two sleep-vulnerable groups – ERMs and college students - this 5-year longitudinal study investigates race-related sleep disparities in a diverse sample of college students during and after the transition to college; and how race-related sleep disparities forecast downstream health and academic outcomes through students’ senior year. The study also investigates the risk and protective effects of ethnic/racial identity as a dynamic and changing moderator during this period. The innovative and novel combination of daily diaries and sleep actigraphy, biannual surveys, and annual assessments of inflammatory biomarkers, telomere length and anthropometric measures offers an unparalleled opportunity to investigate the daily and longer-term mechanisms, pathways, and consequences of race-related sleep disparities in a large sample of ERM and White college students. A key innovation of the study is the intersectional inclusion of ERM, socioeconomic, 1st-generation college, resident and commuter diversity. The three specific aims of the study are informed by strong preliminary data (R21MD011388), scientific premise, and the race-based disparities in stress and sleep in context model. The proposed study: 1. Determines the daily and longer-term impact of sociodemographic and environmental stress on race- related sleep disparities (duration, quality, regularity) during the college transition and the next four years 2. Identifies race-related sleep disparities as an explanatory pathway for sociodemographic and environmental stress to impact health, academic and physiologic biomarker (inflammation and telomere length) outcomes 3. Investigates ethnic/racial identity as a dynamic moderator of the daily and longer-term effects of stress on sleep, and of sleep on outcomes Together, these aims advance developmental and health equity science, investigating how sociodemographic and environmental stress contribute to race-related sleep disparities among diverse college students to forecast daily and longer-term health and academics over time.
