这项研究是NIH帮助结束长期成瘾（HEAL）计划的一部分，旨在加速科学解决国家阿片类药物公共卫生危机。NIH HEAL倡议支持整个NIH的研究，以改善阿片类药物滥用和成瘾的治疗。神经发育过程是由基因和环境之间的动态相互作用形成的。生命早期的适应不良经历会改变发育轨迹，导致有害和持久的发育后遗症。产前和产后危害包括母体物质暴露、怀孕和生命早期的有毒物质暴露、孕产妇健康状况、父母精神病理学、虐待、结构性种族主义和过度压力。为了阐明各种环境危害是如何影响儿童发展的，必须建立一个生命最初10年发展轨迹的规范模板 基于足够大且人口统计学上多样化的美国人口样本。为了实现这一目标，健康大脑和儿童发展国家联盟（HBCD-NC）已经成立，以部署一套协调、优化和创新的神经成像（MRI、EEG）措施，并辅以广泛的行为、生理和心理工具和生物标本，以了解 神经发育轨迹在7,500名母亲和婴儿的样本中，在美国24个地点登记（US）。六溴环十二烷NC将在六溴环十二烷NC行政核心（HCAC）的指导下执行一项共同研究协议，并将在六溴环十二烷NC数据协调中心的指导下收集和向广大科学界分发一个全面和精心策划的研究数据集 （HDCC）。六溴环十二烷NC的总体目标是创建一个全面、协调和高维的数据集，以表征美国儿童的典型神经发育轨迹，并评估生物和环境暴露如何影响这些轨迹。将特别强调 了解产前和产后接触阿片类药物、大麻、酒精、烟草和/或其他物质的影响。为了实现这些广泛的目标，入选的女性样本将包括：1）代表美国人口的种族、民族和社会经济多样性队列; 2）孕妇 使用目标物质（阿片类药物，大麻，酒精，烟草）;和3）人口统计学和行为相似的妇女没有在怀孕期间使用药物，使有效的因果关系推断。此外，六溴环十二烷国家标准将确定关键的发展窗口期，在此期间，有害和保护性环境对人类的影响最大。 对以后神经发育结果的影响。这项研究首次产生的大型、多模态、纵向和可推广的数据集将使用最先进的方法为儿童发展提供新的见解。HBCD-NC研究将为改善全国儿童健康和发展的公共政策提供信息。

This study is part of the NIH’s Helping to End Addiction Long-term (HEAL) initiative to speed scientific solutions to the national opioid public health crisis. The NIH HEAL Initiative bolsters research across NIH to improve treatment for opioid misuse and addiction. Neurodevelopmental processes are shaped by dynamic interactions between genes and environments. Maladaptive experiences early in life can alter developmental trajectories, leading to harmful and enduring developmental sequelae. Pre- and postnatal hazards include maternal substance exposure, toxicant exposures in pregnancy and early life, maternal health conditions, parental psychopathology, maltreatment, structural racism, and excessive stress. To elucidate how various environmental hazards impact child development, it is imperative that a normative template of developmental trajectories over the first 10 years of life be established based on a sufficiently large and demographically diverse sample of the US population. To accomplish this, the Healthy Brain and Child Development National Consortium (HBCD-NC) has been formed to deploy a harmonized, optimized, and innovative set of neuroimaging (MRI, EEG) measures complemented by an extensive battery of behavioral, physiological, and psychological tools, and biospecimens to understand neurodevelopmental trajectories in a sample of 7,500 mothers and infants enrolled at 24 sites across the United States (US). The HBCD-NC will carry out a common research protocol under direction of the HBCD-NC Administrative Core (HCAC) and will assemble and distribute a comprehensive and well-curated research dataset to the scientific community at large under the direction of the HBCD-NC Data Coordinating Center (HDCC). The overarching goal of the HBCD-NC is to create a comprehensive, harmonized, and high-dimensional dataset that will characterize typical neurodevelopmental trajectories in US children and that will assess how biological and environmental exposures affect those trajectories. A special emphasis will be placed on understanding the impact of pre- and postnatal exposure to opioids, marijuana, alcohol, tobacco and/or other substances. To address these broad objectives, the sample of women enrolled will include: 1) a racially, ethnically, and socioeconomically diverse cohort that is representative of the US population; 2) pregnant women with use of targeted substances (opioids, marijuana, alcohol, tobacco); and 3) demographically and behaviorally similar women without substance use in pregnancy to enable valid causal inferences. In addition, the HBCD-NC will identify key developmental windows during which both harmful and protective environments have the most influence on later neurodevelopmental outcomes. The large, multi-modal, longitudinal, and generalizable dataset that will be produced for the first time by this study will provide novel insights into child development using state- of-the-art methods. The HBCD-NC study will inform public policy to improve the health and development of children across the nation.
