HBCD Study Data Release 1.0

This ambitious project, funded through a partnership of a dozen Institutes, Centers, and Offices of the National Institutes of Health, will enroll over 7,000 participating families from across the United States and follow them from pregnancy through early childhood. The HBCD Research Consortium consists of an Administrative Core, a Data Coordinating Center, and 27 research sites across the country.

Leading researchers in the fields of child development and neuroscience will work with participating families and their children to understand how the brain develops and is affected by exposure to substances and other environmental, social, and biological factors during pregnancy and after birth. What we learn from this research will have lasting impacts on future generations of children.

The study will collect information beginning at birth and through early childhood, including anthropometrics (growth measures); medical and family history; biospecimens (samples such as urine and blood); and social, emotional, and cognitive function.​ Structural and functional brain imaging are also done to help see the different parts of the brain and measure activity.
