Abstract More than 50% of youth will experience at least one form of significant adversity in early life. Such adversities pose significant risk not only for the development of psychopathology over the life course, but also for attempted suicide, a leading cause of death in people ages 10-24 years. We have recruited and assessed 220 9- to 13-year-old boys and girls across four timepoints, each two years apart, to examine the effects of exposure to ELS on trajectories of stress reactivity and reward sensitivity, and, in turn, their impact on the onset of psychopathology and suicidal behaviors across adolescence. In this cohort we have conducted repeated measurements of symptoms and diagnoses of psychopathology, neural, endocrine, cognitive, immunological, and behavioral assessments of stress reactivity and reward sensitivity, and early exposure to adversity, including the type, severity, and timing of stressful events. We have published a series of papers from this project elucidating the effects of ELS on psychobiological functioning, trajectories of brain development, and biological aging, and the consequences of these alterations for clinical functioning. In this MERIT renewal application, we propose to build on and extend our work in three important ways. First, we will conduct an additional assessment of our participants at age 20 in order to examine the effects of ELS on trajectories of neurodevelopment and clinical outcomes from childhood to young adulthood, as well as the persistence of COVID-19 pandemic-related difficulties in mental health, stress, and brain metrics. We will also extend our examination of how environmental pollutants and conditions affect relations among these variables. Second, we will extend and replicate our findings in a younger, non-Western sample by analyzing data from the Growing Up in Singapore Towards Healthy Outcomes (GUSTO) project, an ongoing prospective study in which many of the same, or comparable, measures that we administered in our project have also been collected regularly from approximately 1,500 parents and children since the prenatal period. Extending and replicating our findings with the GUSTO dataset, which includes younger, non-Western children from Southeast Asian families in Singapore, will complement findings from other large cohorts, like ABCD and NCANDA, that have assessed only Western participants. Finally, will leverage our own and GUSTO data to examine the effects of the COVID-19 pandemic shutdown on children’s and adolescents’ psychobiological functioning. In both datasets we have a unique opportunity to compare comprehensive psychobiological data collected from the same youth before and after the pandemic shutdowns in order not only to examine how the pandemic has altered young people’s psychobiological functioning and development, but importantly, to also identify risk and resilience factors across cultural contexts. Further, the new proposed adult assessment in our ELS project will allow us to examine the persistence of COVID-related difficulties by re-assessing participants whom we studied soon after pandemic quarantine restrictions ended.

抽象的 超过 50% 的青少年在早年经历过至少一种形式的重大逆境。这样的 逆境不仅对生命过程中精神病理学的发展构成重大风险，而且 自杀未遂，这是 10 至 24 岁人群死亡的主要原因。我们已经招募并评估了 220 名 9 至 13 岁的男孩和女孩在四个时间点（每个时间点相隔两年）进行研究，以检验 暴露于 ELS 对压力反应性和奖励敏感性轨迹的影响，以及它们对 整个青春期出现精神病理学和自杀行为。在这个队列中我们进行了 重复测量症状并进行精神病理学、神经、内分泌、认知、 应激反应性和奖赏敏感性的免疫学和行为评估，以及早期暴露 逆境，包括压力事件的类型、严重程度和时间。我们发表了一系列论文 该项目阐明了 ELS 对心理生物学功能、大脑轨迹的影响 发育、生物衰老，以及这些改变对临床功能的影响。在这个 MERIT 续签申请中，我们建议通过三个重要方式巩固和扩展我们的工作。首先，我们将 对 20 岁时的参与者进行额外评估，以检查 ELS 对 从儿童期到青年期的神经发育轨迹和临床结果，以及 与 COVID-19 大流行相关的心理健康、压力和大脑指标方面的困难持续存在。我们还将 扩大我们对环境污染物和条件如何影响这些变量之间关系的研究。 其次，我们将通过分析来自以下国家的数据，在更年轻的非西方样本中扩展和复制我们的发现： 新加坡成长迈向健康成果 (GUSTO) 项目，这是一项正在进行的前瞻性研究 我们在项目中实施的许多相同或类似的措施也已得到实施 自产前时期以来，定期从大约 1,500 名父母和儿童那里收集数据。扩展和 使用 GUSTO 数据集复制我们的发现，其中包括来自以下国家的年轻非西方儿童 新加坡的东南亚家庭将补充其他大型群体的研究结果，例如 ABCD 和 NCANDA，仅评估西方参与者。最后，将利用我们自己的数据和 GUSTO 数据 检查 COVID-19 大流行关闭对儿童和青少年心理生物学的影响 发挥作用。在这两个数据集中，我们有一个独特的机会来比较全面的心理生物学数据 在大流行关闭之前和之后从同一位年轻人那里收集数据，不仅是为了研究 大流行改变了年轻人的心理生物学功能和发展，但重要的是，也改变了 识别跨文化背景的风险和复原力因素。此外，我们新提出的成人评估 ELS 项目将使我们能够通过重新评估参与者来检查与新冠病毒相关的困难的持续存在 大流行隔离限制结束后不久我们就研究了他。
