Assessment of the Effect of Postprandial Ambulation on Birth Weight Percentile in Patients With Gestational Diabetes Mellitus.
This is a randomized controlled trial to assess the effect of routine exercise counseling compared to the recommendation for postprandial ambulation on infant birthweight among pregnant people with gestational diabetes mellitus. The primary outcome is birthweight percentile for gestational age at delivery. Secondary outcomes include feasibility and acceptability, need for metformin or insulin for glycemic control, mode of delivery, neonatal hypoglycemia. Participants will be counseled to either complete 20 minutes of walking after meals, or be counseled with routine exercise counseling of 30 minutes of low-impact 5x a week. Their activity will be tracked by FitBit pedometers and uploaded via bluetooth to a database for review. They will continue to receive routine obstetric and diabetes care.
• Patients who are diagnosed with gestational diabetes and receive care at the Maternal Fetal Medicine Diabetes in Pregnancy Program and who are fluent in English or Spanish.
