Subjects randomized to routine care will receive their care in the usual diabetic clinic attended by residents and faculty. They will receive consultation with the diabetes educator at diagnosis and as needed. Patients are seen every 2 weeks (or more by provider discretion) until 37 weeks and weekly until delivery. Visits are 10-15 minutes and focus on routine screening tests and review of blood sugar logs/medication titration. Each subject's medical chart will be reviewed for demographics, antenatal management, maternal and neonatal outcomes.

Group visits will be held every 2 weeks in a continuous cycle through a four session curriculum. Women will have weekly visits beginning at 37 weeks with traditional prenatal visits on the weeks when the group does not meet. Groups of 4-12 women will meet for two hour visits and much of that time will be spent on pregnancy, behavioral health, diabetes and nutrition education. Groups will be co-facilitated by 2 CenteringPregnancy trained providers at each site and an obstetric provider. Women may be instructed to have additional visits in the traditional clinic at the discretion of the obstetric provider.

Women will receive their prenatal care in a group rather than in the 1:1 traditional manner.
