Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Postpartum GDM
Women with GDM diagnosed early (\< 20 weeks gestation) or with routine 3rd trimester screening (\>=24 weeks) will be enrolled in this longitudinal study. All enrolled women will complete a oral glucose tolerance test and wear a continuous glucose monitor for 10 days at the 3 designated study time points (0-4 days, 4-6 weeks, and 6 months after delivery).
2-hour 75-g oral glucose tolerance test and Dexcom G6 Pro continuous glucose monitor
All women enrolled in this study will have a 2-hour 75-g oral glucose tolerance test performed immediately postpartum (within 4 days of delivery), at 4-6 weeks postpartum, and at 6 months postpartum. Enrolled women will also wear a continuous glucose monitor for 10 days at each of these time periods. Both women and their infants will have skin fold thickness measured at each of these 3 study visits to estimate body fat composition. Additionally umbilical cord blood and placental biopsies will be collected at delivery and stored for future research.
