Opioid use during pregnancy is associated with adverse outcomes for pregnant individuals and offspring. The mechanisms through which these outcomes arise and the consequences of prenatal opioid exposure on child health and development remain largely unexplored. The HEALthy Brain and Child Development (HBCD) Study is a nationwide longitudinal prospective study of early child development that will assess a broad spectrum of biological, behavioral, social, and health factors among 7,500 pregnant women and their children from pregnancy to mid-childhood. This supplement will expand the biospecimen collection of the HBCD protocol at the University of North Carolina at Chapel Hill to include delivery specimens (placenta, cord tissue, and cord blood). This will provide an unprecedented resource-generating opportunity for the larger scientific community to comprehensively evaluate mechanisms that mediate the connection between substance use during pregnancy and adverse neonatal, infant, and/or maternal health outcomes and inform innovative preventive strategies.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) will establish a normative model of developmental trajectories over the first 10 years of life. All sites in the HBCD-NC will carry out a common research protocol and will assemble and distribute a comprehensive and well curated research dataset to the scientific community at large. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. Most participants will be recruited in the second trimester of pregnancy, with a smaller subset recruited at birth, and followed for the first 10 years of life. The Children’s Hospital of Los Angeles study site will enroll participants from across the Greater Los Angeles region, where the prevalence of legal and illegal non-opioid drug use is high, enabling researchers to recruit from diverse, high-risk populations.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) will establish a normative template of developmental trajectories over the first 10 years of life. All sites in the HBCD-NC will carry out a common research protocol and will assemble and distribute a comprehensive and well curated research dataset to the scientific community at large. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. Most participants will be recruited in the second trimester of pregnancy, with a smaller subset recruited at birth, and followed for the first 10 years of life. The University of New Mexico Health Science Center study site is in a largely rural/mixed state with one of the highest rates of overdose in the nation. This site will enroll diverse mother-infant pairs and partners or caregivers, including Hispanic/Latinx and American Indian individuals.

The first ten years of life are accompanied by rapid changes to the developing brain and cognitive abilities. Complex interacting factors including genetics, early-life exposure to substances, family and social interactions, and home and community environments can affect brain and cognitive development. Three linked projects aim to develop effective research protocols to lay a foundation for a future HEALthy Brain and Cognitive Development (HBCD) birth cohort study. Project 1 will develop protocols for recruitment and retention of a diverse sample of pregnant and postpartum women with oversampling of mothers with prenatal opioid use. Project 2 will identify ethical, legal, and regulatory challenges for investigations in this vulnerable population and define effective solutions to enable recruitment and study of these participants. Project 3 will develop and evaluate protocols for acquiring high-quality, quantitative neuroimaging measures with magnetic resonance imaging and functional near infrared spectroscopy and assess effective strategies for measuring cognitive performance in young children, including those exposed to opioids.

This study aims to determine how exposure to opioids and other substances affects the developing fetal brain and shapes later child cognitive outcomes. Researchers will collect neuroimaging and behavioral data, as well as measures of environmental exposures related to social equity, COVID-19, and socioeconomic factors. The project will reduce traditional barriers to participation by using innovative data collection methods and mobile labs to bring the research to underrepresented and marginalized communities. This approach aims to clarify the impact of substance exposure on child development through an equitable approach to research, with generalizable findings. The study will take place at Rhode Island Hospital, where participants will be drawn from a largely rural population.

A more than 5-fold increase in the incidence of neonatal abstinence syndrome has been reported since 2000. Preliminary studies show that prenatal opioid exposure is associated with increased risk of impaired neurodevelopment. Five institutions (Duke University, Arkansas Children’s Research Institute, Cincinnati Children’s Hospital, University of Illinois at Urbana–Champaign, and University of North Carolina at Chapel Hill) have formed a consortium to develop strategies for the Phase II HEALthy Brain and Child Development Study. Research teams will develop instruments and strategies (recruitment/retention protocols, assessment batteries, and novel tools); conduct pilot studies (fetal and postnatal imaging, advanced imaging harmonization and quality control, assessment administration, biosampling) to evaluate instruments; and analyze available data, including imaging, behavioral, cognitive, and maternal data from studies on early brain development, to guide the Phase II study design. Upon completion, the consortium aims to conduct the Phase II study.

Rates of neonatal abstinence syndrome have reached a staggering 6.5 per 1,000 births nationwide, creating an urgent need to identify how in-utero exposure to opioids and associated risk factors influence the developing brain. A multidisciplinary team will address these challenges in Oregon, a state particularly hard hit by the opioid epidemic. Through linking sites, the impact of the Phase I project is enhanced and will provide critical information to support a national-level effort for Phase II of the HEALthy Brain and Child Development Study. Aim 1 will develop, implement, and evaluate innovative recruitment and retention strategies for high-risk populations. Aim 2 will address anticipated challenges of the planned Phase II study by implementing and evaluating a multi-site, standardized research protocol including multimodal MRI of placenta, fetus, neonate, and 24-month-old brain; biospecimen collection; and assessment of substance use and other key domains. Aim 3 will evaluate data acquisition, processing, and statistical considerations to maximize data quality, usability, and integration across sites.
