PROJECT SUMMARY Air pollution can impact cognitive disorders such as attention deficit hyperactivity and behavioral problems. Children are particularly vulnerable to environmental exposures because of the sensitive nature of child development, a life stage marked by rapid cell differentiation. A growing body of literature on air pollution shows increasingly diverse effects on childhood health, development and disease. This research study will further add to the literature by both addressing the main effect of air pollution on sleep and the modifying effect of co- exposure to social stressors. Specifically, we will examine potential relationships between ambient air quality and its effects on sleep patterns among children, 6-7 years old. Specific Aim are to: 1) Determine the association of prenatal PM2.5 exposure and child sleep quantity and awakening at night assessed at 6-7 years using a satellite remote sensing PM2.5 model and wrist-worn continuous actigraphy over 7 days; 2) Determine if early life stress indexed by negative life events, maternal trauma, and exposure to violence predicts sleep quantity and awakening at night and modifies the impact of prenatal PM2.5 on sleep assessed at age 6-7 years. By identifying risk factors for poorer sleep phenotypes, we can begin to address interventions targeting toxic impacts on child health. Furthermore, I posit that ambient air quality and sleep may work independently or synergistically through a shared inflammatory pathway, and thus a better understanding of this relationship could mitigate modifiable risk factors that improve childhood health outcomes. It is further postulated that this proposed research will contribute to the sparse literature on air quality and sleep health among children by examining pediatric environmental health, ambient air quality and potential stress induced modifying effects on sleep patterns in children. Using the Programming Research in Obesity, Growth, Environment and Social Stressors (PROGRESS) longitudinal birth cohort study to conduct the proposed research, this study will expand the literature on sleep and sleep disparities, a research void that if addressed has the potential to mitigate the adverse impact of child sleep disparities on long term health.

项目概要 空气污染会影响认知障碍，例如注意力缺陷多动和行为问题。 由于儿童的敏感天性，儿童特别容易受到环境暴露的影响 发育，以快速细胞分化为标志的生命阶段。越来越多的有关空气污染的文献表明 对儿童健康、发育和疾病的影响日益多样化。本研究将进一步补充 通过解决空气污染对睡眠的主要影响和其他因素的改变作用来查阅文献 暴露于社会压力源。具体来说，我们将研究环境空气质量之间的潜在关系 及其对 6-7 岁儿童睡眠模式的影响。具体目标是： 1) 确定关联 使用卫星评估 6-7 岁时的产前 PM2.5 暴露以及儿童睡眠时间和夜间觉醒情况 遥感 PM2.5 模型和腕戴式连续体动记录仪 7 天以上； 2) 确定早期生活压力是否 以负面生活事件、产妇创伤和暴力接触为索引，可预测睡眠时间和 夜间醒来并改变产前 PM2.5 对 6-7 岁时评估的睡眠的影响。通过识别 睡眠表型较差的危险因素，我们可以开始针对对儿童的有毒影响采取干预措施 健康。此外，我认为环境空气质量和睡眠可以独立发挥作用，也可以通过以下方式协同作用： 共享的炎症途径，因此更好地理解这种关系可以减轻可改变的影响 改善儿童健康结果的风险因素。进一步假设这项拟议的研究将 通过检查儿科，为有关儿童空气质量和睡眠健康的稀疏文献做出贡献 环境健康、环境空气质量和潜在压力对睡眠模式的影响 孩子们。使用肥胖、生长、环境和社会压力因素的编程研究（进展） 纵向出生队列研究来进行拟议的研究，这项研究将扩大有关睡眠的文献 和睡眠差异，这一研究空白如果得到解决，有可能减轻儿童的不利影响 睡眠差异对长期健康的影响。
