Intervention: Diabetes Prevention Program
Description: Phase 1 (core curriculum) of the Diabetes Prevention Program consists of 16 sessions and will take place during Week 18 of pregnancy through Week 33. Participants will receive the DPP curriculum via virtual pre-recorded sessions to which participants will have access. A research coordinator will follow up with each study participant by phone once weekly. If participants do not make adequate progress, the coordinator will assess how much extra time the participant will need to complete each session and will work with the participant if needed. Phase 2 (post-core curriculum) consists of 6 sessions and will be completed after delivery, between Week 6 and Week 20 postpartum. Participants will re-engage into the DPP with an orientation session at Week 6 postpartum. The same session completion format and procedure for inadequate progress will be followed as during pregnancy.
