PROJECT SUMMARY / ABSTRACT More than one in five adolescents will experience a mental health disorder, including depression and anxiety, and the prevalence of these conditions is increasing. Among adolescents, depression and anxiety are linked to increased risk of suicide, a leading cause of death in this age group. Identifying underlying and modifiable contributors to these conditions is crucial as current research and interventions focus on screening and treatment rather than prevention. Here, we posit that air pollution, in addition to genetic susceptibility, social determinants, familial and school issues, and other factors, is a contributor to mental health disorders. Toxicological studies demonstrate that fine particulate matter (PM2.5) and traffic-related air pollution (TRAP) are neurotoxic, and epidemiologic studies consistently link these pollutants to reduced cognitive abilities and increased externalizing behaviors. However, few studies have prospectively evaluated the role of air pollution exposure on mental health disorders in childhood. Recently, we found that childhood air pollution exposure is associated with increased risk for depression and anxiety at age 12 years. However, the role of air pollution in the onset and persistence of mental health disorders during adolescence, and changes in brain structure, organization, and function linked to these outcomes, remain poorly understood. Therefore, we hypothesize that exposure to air pollution during critical periods of brain development, including adolescence, is associated with adverse mental health outcomes. We will leverage existing longitudinal data from the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS) and the Health Outcomes and Measures of the Environment (HOME) Study, two prospective cohorts located in Cincinnati, Ohio, to address this hypothesis. Both cohorts have been followed from birth and evaluated with concordant measures of mental health and neuroimaging at age 12 years. We will conduct new follow-up at age 18 years to assess the onset and persistence of mental health outcomes through adolescence and apply validated models for PM2.5 and TRAP to characterize air pollution exposure from conception through age 18 years. We will also acquire novel neuroimaging outcomes, including brain -aminobutyric acid and glutathione concentrations accompanied by anatomical and functional magnetic resonance imaging. Our aims are to: 1) determine the association between exposure to PM2.5 and TRAP during distinct developmental periods and the onset and persistence of mental health outcomes in adolescence; 2) determine the association between exposure to PM2.5 and TRAP during distinct developmental periods and neuroimaging outcomes in late adolescence; and 3) determine whether changes in brain volume, organization, metabolism, and function mediate associations between PM2.5 and TRAP exposure and mental health outcomes. Examining air pollution as a novel and modifiable risk factor will provide critical data to guide primary prevention aimed at reducing the burden of mental health disorders in adolescence.

项目总结/摘要 超过五分之一的青少年会经历心理健康障碍，包括抑郁和焦虑， 并且这些病症的流行率正在增加。在青少年中，抑郁和焦虑与 自杀风险增加，这是该年龄组死亡的主要原因。确定基础和可修改的 这些条件的贡献者是至关重要的，因为目前的研究和干预措施的重点是筛选和 治疗而不是预防。在这里，我们重申，空气污染，除了遗传易感性，社会 决定因素、家庭和学校问题以及其他因素是造成心理健康障碍的一个因素。 毒理学研究表明，细颗粒物（PM2.5）和交通相关的空气污染（TRAP） 神经毒性和流行病学研究一致认为这些污染物会降低认知能力， 外化行为增加。然而，很少有研究对空气污染的作用进行前瞻性评估 儿童期精神健康障碍的风险。最近，我们发现儿童期空气污染暴露是 与12岁时抑郁和焦虑的风险增加有关。然而，空气污染在 青春期心理健康障碍的发作和持续，以及大脑结构的变化， 对与这些成果有关的组织和职能仍然知之甚少。因此，我们假设 在大脑发育的关键时期（包括青春期）暴露于空气污染与以下因素有关： 不良心理健康后果。我们将利用现有的纵向数据从辛辛那提童年 过敏和空气污染研究（CCAAPS）以及环境的健康结果和措施 （HOME）研究，位于俄亥俄州辛辛那提的两个前瞻性队列，以解决这一假设。两个队列 从出生起就被跟踪，并通过心理健康和神经影像学的一致措施进行评估， 年龄12岁。我们将在18岁时进行新的随访，以评估精神分裂症的发作和持续时间。 通过青少年的健康结果，并应用经验证的PM2.5和TRAP模型来描述空气 从怀孕到18岁的污染暴露。我们还将获得新的神经影像学结果， 包括脑内γ-氨基丁酸和谷胱甘肽浓度， 磁共振成像。我们的目标是：1）确定暴露于PM2.5和 不同发育时期的TRAP与儿童心理健康结果的发生和持续 青春期; 2）确定在不同发育阶段暴露于PM2.5和TRAP之间的关联 青春期后期的月经周期和神经成像结果;以及3）确定脑体积的变化， 组织，代谢和功能介导PM2.5和TRAP暴露与心理之间的关联 健康成果。将空气污染作为一种新的和可改变的风险因素进行研究，将为指导 初级预防旨在减轻青少年心理健康障碍的负担。
