Funded Projects

This study will determine the feasibility of a multifaceted approach to recruitment of normal and high-risk pregnant women and their children. Three inter-related tasks will support this comprehensive feasibility study. First, an interdisciplinary summit will occur early in the study focused on how best to mitigate risks and maximize benefits to children and families recruited in a future cohort. Second, the feasibility of a multi-faceted recruitment strategy will be assessed. Third, select pregnancy and birth assessments will be collected from recruited participants in this feasibility study while leveraging data across early childhood from existing resources, to inform Phase II study planning. This Phase I of the FL-DECADE study will provide valuable planning and feasibility data to be used for the national efforts to build a large, prospective cohort.

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 research dataset to the scientific community. 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. This study will be based out of the Children’s Hospital of Philadelphia and the University of Pennsylvania and will represent an urban population with a wide socioeconomic status range.

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 objective of the HBCD PRELUDE (Prenatal Experiences and Longitudinal Development) multi-site consortium is to characterize typical brain development from birth through childhood. All sites in this consortium will measure the influence of key biological and environmental factors on child social, cognitive, and emotional development. Researchers will assess how prenatal exposure to opioids and other substances, as well as other adverse environmental factors, affect brain development and other child health outcomes. The study site at the University of North Carolina, Chapel Hill will work with Wake Forest University to help recruit pregnant women with substance use disorders and enroll mother-infant dyads. This collaboration serves to expand participant diversity and extend recruitment to cover a larger region of North Carolina, a state hit hard by the opioid crisis.

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.

Despite increased efforts to understand the neurodevelopmental sequelae of in utero opioid and other substance exposure on long-term behavioral, cognitive, and societal outcomes, important questions remain, specifically, 1) How is brain growth disrupted by fetal substance and related pre- and post-natal exposures? and 2) How are these disrupted growth patterns causally related to later cognitive and behavioral outcomes? This project seeks to formulate an approach to addressing these key questions and decipher the individual and cumulative effect of these intertwined pre- and post-natal exposures on child neurodevelopment. First, researchers will address the legal, ethical, and mother-child care and support concerns implicit in this study. Next, they will integrate across our areas of neuroimaging expertise to develop, implement, and harmonize a multi-modal MRI and EEG protocol to assess maturing brain structure, function, and connectivity. Finally, researchers will develop and test advanced statistical approaches to model and analyze this multidimensional and longitudinal data.

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.

Researchers at the University of Alabama at Birmingham and the University of Alabama will enroll pregnant women during their second trimester and follow their infants through a comprehensive longitudinal study. This program will follow 300 mother-infant pairs to understand how early life exposure to drugs and other environmental factors affects developmental trajectories. In addition, this program will determine how genetic and biological factors interact with environmental factors to influence neurodevelopment. This study will take place at the University of Alabama at Birmingham, recruiting participants from mainly rural populations with low access to obstetric/gynecological (OB/GYN) care and high rates of substance use.

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. The majority of participants will be recruited in the second trimester of pregnancy, with a smaller subset recruited at birth, and followed for the first decade of life. The University of Vermont study site will recruit mother-infant dyads from a rural area in Vermont, a state in which nearly one-third of neonatal hospitalizations are for neonatal abstinence syndrome (NAS).

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.
