Review our study objectives, design, protocols and more
HBCD’s comprehensive protocol includes assessments of children’s physical, emotional, and cognitive development, plus surveys of parental health and well-being. The HBCD study features wearable biosensors to calculate infant heartbeat and movement, biospecimen collection for genetic and epigenetic analyses and measurements of environmental and substance-use exposures, and multimodal neuroimaging and EEG across neurodevelopment. These assessments are distributed across in-person and remote visits during an initial 5-year period. Visits are scheduled at variable intervals designed to capture developmental trajectories. We are anticipating extension for a second 5-year period.
