The Sweet Pea Study


The Sweet Pea Study

The Sweet Pea Study is a short-term nutrition research study designed to look at how the health of a mother during pregnancy may influence her child’s brain development.

This study is for moms who:

  • Are less than 36 weeks pregnant
  • Have a BMI of either 18.5 – 25 OR
  • Have a BMI greater than 30
  • Are healthy
  • Are 18 years of age or older
  • Conceived without the use of fertility treatments or medications

If you decide to participate in this study, you will be asked to complete 1 pre-natal visit at about 36 weeks at which we will evaluate medical history and dietary intake, take blood and stool samples, and measure your weight, height, vital signs, body composition, IQ, and anxiety and depression. You will also wear a device to monitor your physical activity for about 5 days after this visit. This visit will take 1-2 hours and compensation is $50.

The second visit of the study occurs about 2 weeks after the baby is born. For the newborn visit, we will measure your baby’s size and feeding activity, collect blood and stool samples, and record your baby’s brain activity using an MRI and EEG. This visit will take 2-4 hours and compensation is a 6 month supply of diapers.
