The first few years of life are a time of rapid growth and brain development. The HBCD Study will help us better understand how a child may be shaped by experiences and conditions in pregnancy and early life. These include social and environmental experiences in early life and exposure to substances (such as opioids, alcohol, tobacco, and cannabis) during pregnancy. 

You may be eligible for this study if you meet the following criteria.

Key Criteria:

• Pregnant individuals ages 18+
• Do not have a 4-year college degree
• Live within 50 miles of the Boston area
• Speak English or Spanish
• Plan on staying in the area after the child is born
• Plan on being one of the primary caregivers for the child

The HBCD Study begins with 3-4 visits in the first year with only 1-2 visits in subsequent years. During these visits, you will be asked to complete interviews and questionnaires.

In addition, you and/or your child will be asked to:

• Provide samples, such as blood (from mom) and saliva
• Participate in behavioral assessments
• Wear activity and/or heart rate trackers for brief periods of time
• Undergo safe, non-invasive methods that provide pictures of your child’s brain and measure the brain activity of your child

Receive up to $2,010 over the first 5 years, plus free transportation to and from study visits (Uber, rideshare, or gas reimbursement).

All study assessments and procedures will be provided to you free of charge.
