Clinical Trial Summary

The investigators primary objective is to conduct a randomized trial to determine the effect of diabetes group prenatal care on glycemic control and postpartum weight retention in women with type 2 diabetes and gestational diabetes.

Description:

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).
