This multi-site consortium research study, entitled the HEALthy Brain and Child Development (HBCD) study, willprospectively examine human brain, cognitive, behavioral, social, and emotional development beginning prenatallythrough age 10 years. The study will determine the short- and long-term impacts of a variety of potentially harmfulas well as protective environmental factors. These include prenatal substance use, mental health, stress,sociodemographics, biological and genetic factors, and parent/child interaction. The overall goal of this study is tounderstand the neurodevelopmental trajectories of children growing up in diverse environments. A sample of~7,500 pregnant women will be recruited from 25 sites across the U.S. and they and their liveborn children will befollowed for 10 years.

If you agree for you and your child to participate, we will ask you to take part in completing visits from pregnancy through the first 10 years of your child’s life. These visits will take place both in-person and remotely. The length of visits will vary and may last between approximately one to nine hours per visit (which can be broken up into multiple visits). Over the first four years of the study, all study visits will require about 33-37 hours total. This will include interviews, questionnaires and other tests about yourself and your child. We will ask you and your child to wear small devices for a few days to measure heart rate and or movement. We will ask you and your child to provide some biological samples. Because this study is looking at how a child’s brain develops in the first years of life, we will ask that you allow your child to have brain scans and other measures of how your child’s brain is developing. This study is being offered in both State College, PA at the University Park campus and in Hershey, PA at the College of Medicine campus. You may choose to complete this study at either site.
