Additional Study Information: We are working to address the racial disparities in birth outcomes, a pressing issue in women's health research. In particular, we want to better understand the role that mood, stress, and inflammation play in the development of your baby. In our study, participants are asked to engage in up to 3 in-person prenatal sessions at Columbia University Medical Center (168th Street). These sessions are expected to take up to 4.5 hours total. You will have blood drawn and provide hair and saliva samples. At the third trimester session, participants will play a word and color-matching game while we collect physiological data from the mother and baby in utero (ie: fetal heart rate). You will also complete questionnaires online the day before your appointment and once you return home from your appointment. Compensation is up to $410 along with a newborn gift!
