Social-Environmental Predictors of Sleep Disparities During the Transition toCollege

项目摘要 少数族裔(ERM)更容易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对ERM的影响不成比例，并产生了 与与种族有关的睡眠不平等的发展和维持有关。向大学的过渡 是研究睡眠的一个特别重要的时间，因为年轻人遇到了独特的 与睡眠有关的社会人口和环境压力因素。不再受制于高中早期开学 时间越长，大学生报告的时间越晚，就寝时间也越不规律。大学生的睡眠也越来越少 比成年人差，这表明年轻人的睡眠障碍处于发育高峰。 这项为期5年的纵向研究聚焦于两个睡眠弱势群体--ERM和大学生 在不同样本的大学生中调查了与种族有关的睡眠差距 向大学的过渡；以及种族相关的睡眠差距如何预测下游的健康和学业 学生最后一年的成绩。该研究还调查了以下物质的风险和保护作用 在这一时期，族裔/种族认同是一个充满活力和不断变化的主持人。 将日常日记和睡眠活动记录、两年一次的调查和一年一次的 炎性生物标记物、端粒长度和人体测量的评估提供了无与伦比的 有机会调查种族相关的日常和长期机制、途径和后果 ERM和白人大学生大样本中的睡眠差异。这项研究的一个关键创新是 跨部门包容环境管理、社会经济、第一代大学、居民和通勤者的多样性。这个 这项研究的三个具体目标由强大的初步数据(R21MD011388)、科学前提、 以及基于种族的压力差异和睡眠背景模型。建议的研究： 1.确定社会人口和环境压力对种族的日常和长期影响-- 在大学过渡期间和接下来的四年中相关的睡眠差异(持续时间、质量、规律性) 2.确定与种族相关的睡眠差异是社会人口和 环境压力对健康、学术和生理生物标志物(炎症和端粒)的影响 长度)结果 3.调查民族/种族认同对压力的日常和长期影响的动态调节作用 睡眠，以及睡眠对结果的影响 这些目标共同推动了发展和健康公平科学，调查了社会人口 以及环境压力导致不同大学生之间与种族有关的睡眠差距 随着时间的推移，预测每天和更长期的健康和学术活动。

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.
