Glucose Testing in GDM: Adherence to One- Versus Two-hour Postprandial Glucose Monitoring in Gestational Diabetics
Adherence to One- Versus Two-hour Postprandial Glucose Monitoring in Gestational Diabetics: A Randomized Trial
The purpose of this study is to evaluate if in patients with gestational diabetes (GDM), adherence to postprandial glucose monitoring differs when performed 1-hour versus 2-hours after eating.
The primary objective of this study is to evaluate difference in rate of adherence (binary outcome defined as <80% or ≥80% of glucose log completed) between gestational diabetics who perform 1-hour versus 2-hour postprandial blood glucose testing.

Description
Inclusion Criteria:
- Pregnant patients with singleton gestation who are ≥ 18 years of age.
- Diagnosis of GDM after 24 0/7 weeks.
- For diagnosing GDM, a two-step screening algorithm will be performed according to the American College of Obstetrics and Gynecologists.4 Specifically, a 1-hour 50-g glucose-loading test is given first. Plasma glucose levels between 140 and 200 mg/dL will be considered elevated. Confirmatory testing will then be performed using a 3-hour 100-g glucose tolerance test. Diagnosis was made when two of the four values were elevated. Abnormal glucose value thresholds are established via the criteria suggested by Carpenter and Coustan: fasting value ≥ 95 mg/dL, 1-hour ≥ 180 mg/dL, 2-hour ≥ 155 mg/dL, and 3-hour ≥ 140 mg/dL.9 Patients with a blood glucose level greater than 200 mg/dL after 1-hour 50-g glucose-loading test will be diagnosed with GDM without requirement for the 3-hour 100-g glucose tolerance test.
Exclusion Criteria:
- Type 1 pre-gestational diabetes
- Type 2 pre-gestational diabetes
- GDM diagnosed prior to 24 0/7 weeks gestation.
