Clinical Trial Summary

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.


Description:

This is a randomized controlled trial of postprandial ambulation to decrease birthweight percentile in patients with gestational diabetes. Patients who are diagnosed with gestational diabetes. and enrolled in the Diabetes in Pregnancy Program in the Division of Maternal Fetal Medicine at Women and Infants Hospital of Rhode Island will be approach for inclusion in the study. After consent is obtained, patients with gestational diabetes. will be randomized into one of two groups. - Group 1: intervention group: 20 minutes of walking after meals - Group 2: non-intervention group: routine activity Randomization will occur via computer generated randomization in blocks of 10. After consent is obtained the participants will be randomized via REDCap. They will then receive counseling specific to their group. They will be provided with an activity monitor and instructed on how to use as well as charge and upload data. They will be provided with the information from the manufacturer as well as trouble shooting guide. As is the standard of care in this clinic, both groups would be equipped with glucometers and diabetic testing supplies. Both groups would receive the same diabetes and nutrition counseling from qualified nursing staff. Additionally, all participants will be provided with Bluetooth enabled pedometers. Those participants assigned to the intervention group would be instructed to walk for 20 minutes within the first two hours following each meal, while those assigned to the routine activity group will receive standard exercise counseling per American College of Obstetricians and Gynecologists and the American Diabetes Association. Patients will touch base weekly (either in person or by email) with diabetic nurse educators as is the standard management in this clinic. The decision to start insulin for glucose management will remain up to the discretion of the participant's medical doctor. In addition to review of their glucose logs, patients will review activity log and pedometer data with research staff on a weekly or biweekly basis. Delivery data will be collected on all patients including routine postpartum laboratory data.
