Pregnancy 24/7 Study

                       Pregnant Woman

We have reached out recruitment goal of 125 participants! We are no longer enrolling participants. 


Pregnancy 24/7 is a 5-year observational cohort study funded by the National Institutes of Health. In this study, we examined 24-hour behavioral patterns (sedentary behavior, sleep, and physical activity) in each trimester of pregnancy. We assessed whether these behavioral patterns are related to hypertensive disorders of pregnancy and other pregnancy complications. The goal of this work is to identify optimal behavioral patterns during pregnancy to reduce women's risk of pregnancy complications and to improve future health outcomes for the mother and baby. 


The purpose of this study was to measure patterns of movement and health in women who are pregnant. We recruited a total of 125 women to take part in this study. Participants must be in their first trimester and between 18-45 years old. 

Participants had one in-person visit and two virtual visits (three study visits total), one each trimester of pregnancy.
