Group Versus Traditional Prenatal Care for Diabetes

Long term, the investigator aims to test the central hypothesis that group prenatal care,
compared to traditional prenatal care, will improve, 1.) glycemic control and, 2.) postpartum
weight retention in women with type 2 and gestational diabetes. The objective of this
proposal is to conduct a randomized trial in two phases to determine the effect of Diabetes
Group Care (GC) on glycemic control in pregnant women with T2DM and GDM (Antepartum Phase)
and the impact on postpartum weight retention (Postpartum Phase).
