Education and health disparities by race/ethnicity and socioeconomic status (SES) are well documented among adolescents. Sleep, a health behavior, may be a fundamental mechanism contributing to both. Teenagers are the least likely of any age group to get sufficient sleep and there are racial/ethnic and SES disparities in sleep quantity and quality. Multilevel (individual, family, neighborhood) stressors may also contribute to disparities in sleep, education and health. The goal of our project, Effects of Sleep on Education and Health Outcomes Among Adolescents, is to use objective measures of sleep (duration, timing, quality) to examine if sleep deprivation among teenagers is related to education and health. Our prospective study of a diverse sample of teens will enable us to investigate the temporal relationships among sleep, education and health outcomes. Our specific aims are to : 1) investigate if sleep mediates the relationship between race/ethnicity/SES and education and health outcomes; 2) determine if sleep mediates the relationship between multilevel measures of stress and education and health outcomes; and 3) examine whether differential exposures to multilevel stressors partially account for ethnoracial and SES disparities in sleep. In a two-year, multiple-wave cohort study we will follow ~540 9th grade students from two high schools in a semi-rural area in north-central Georgia. Wrist-worn accelerometers will provide objective measures of sleep duration, timing, and quality and collected during Spring of 9th grade and again for the same students during Fall of 10th grade. These data will be linked to extensive student-level education (grades, reading skills, standardized test scores, tardiness, attendance, disciplinary referrals and suspensions) and health (self-rated mental and physical health and health-related absences) outcomes from two time periods of those enrolled (9th and 10th grades). Multilevel stressors (individual-level stress/discrimination, family-level home chaos, neighborhood-level disadvantage) will be obtained from surveys and publicly available data in both 9th and 10th grades. Data on potential covariates will be collected including: 1) objectively measured physical activity using actigraphy when sleep measures are obtained; 2) objectively measured body mass index and cardiorespiratory fitness in 9th grade; and 3) individual data from survey modules administered during 9th and 10th grades assessing student characteristics (e.g., race/ethnicity, sex, puberty, employment, social support, screen time), and family characteristics (household structure). Multi-level causal mediation analysis will decompose the contribution of sleep quality and quantity to race/SES disparities in education and health outcomes. This project exemplifies a unique partnership between education and public health sectors with results having practical value to a wide range of sectors and organizations. Results may find that sleep deprivation, a common yet modifiable risk factor, is a mechanism for education and health disparities. This research will lead to the development and implementation of larger scale longitudinal and intervention studies.

按种族/族裔和社会经济地位划分的教育和健康差异有据可查 在青少年中。睡眠是一种健康行为，可能是促进两者的基本机制。 青少年是所有年龄组中最不可能获得充足睡眠的 还有种族和社会经济地位 睡眠数量和质量的差异。 多层次（个人、家庭、邻里）压力源也可能 造成睡眠、教育和健康方面的差异。我们项目的目标，睡眠对教育的影响 和青少年健康结果，是使用客观的睡眠措施（持续时间，时间，质量）， 研究青少年睡眠不足是否与教育和健康有关。我们的前瞻性研究 不同的青少年样本将使我们能够调查 睡眠、教育和 健康成果。我们的具体目标是：1）调查睡眠是否介导了 种族/民族/SES与教育和健康结果; 2）确定睡眠是否介导了这种关系 压力和教育和健康结果的多层次措施之间;和3）检查是否 不同的暴露水平的压力源，部分解释了种族和社会经济地位的差异，在睡眠。 在一项为期两年的多波队列研究中，我们将跟踪来自两所高中的约540名9年级学生， 格鲁吉亚中北部的一个半农村地区。腕戴式加速度计将提供客观的睡眠测量 持续时间，时间和质量，并在9年级的春天收集，并再次为同一学生在 十年级的秋天。这些数据将与广泛的学生教育（成绩，阅读技能， 标准化考试成绩、迟到、出勤、纪律推荐和停职）和健康（自我评价 心理和身体健康和健康相关的缺席）的结果从两个时间段的那些登记（第九届 10年级）。多层次的压力源（个人层面的压力/歧视，家庭层面的家庭混乱， 邻里水平的劣势）将从调查和公开数据中获得第9和第10届 成绩将收集潜在协变量的数据，包括：1）使用 当获得睡眠测量值时，进行体动记录; 2）客观测量体重指数和心肺功能 9年级的健康状况;以及3）来自9年级和10年级期间管理的调查模块的个人数据 评估学生特征（例如，种族/民族、性别、青春期、就业、社会支持、屏幕时间）， 家庭特征（家庭结构）。多层次的因果中介分析将分解 睡眠质量和数量对教育和健康结果中种族/SES差异的贡献。 该项目体现了教育和公共卫生部门之间的独特伙伴关系， 对广泛的部门和组织具有实用价值。结果可能会发现，睡眠剥夺， 常见但可以改变的风险因素是造成教育和健康差距的机制。这项研究将导致 发展和实施更大规模的纵向和干预研究。
