Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control Arm
Patients in the control arm will be instructed to check blood sugars seven times per day: fasting, pre-prandial, and 1 hour after each meal. The glycemic targets for the control arm will be defined as follows: fasting ≤95 mg/dL, pre-prandial ≤95 mg/dL, and 1-hour postprandial ≤140 mg/dL (i.e. conventional targets). Patients who do not achieve glycemic goals with diet and exercise will be started on medical therapy (metformin or insulin) at the discretion of a maternal-fetal medicine subspecialist and endocrinologist.
No interventions assigned to this group
Interventional Arm
Patients in the experimental arm will be instructed to check blood sugars seven times per day: fasting, pre-prandial, and 1 hour after each meal. The glycemic targets for the intervention arm will be defined as follows: fasting ≤80 mg/dL, pre-prandial ≤80 mg/dL, and 1-hour postprandial ≤110 mg/dL. Patients who do not achieve glycemic goals with diet and exercise will be started on medical therapy (metformin or insulin) at the discretion of a maternal-fetal medicine subspecialist and endocrinologist.
Glycemic Targets
The intervention is glycemic targets that are lower than those currently recommended by ADA and ACOG: fasting ≤80 mg/dL, pre-prandial ≤80 mg/dL, and 1-hour postprandial ≤110 mg/dL instead of fasting ≤95 mg/dL, pre-prandial ≤95 mg/dL, and 1-hour postprandial ≤140 mg/dL.
