Abstract

Objective To evaluate whether women with gestational diabetes mellitus (GDM) enrolled in an intensive behavior education program (IBEP) demonstrate lower mean fasting glucose levels on the 2-hour 75 g oral glucose tolerance test (2-hour OGTT) at 6 to 12 weeks postpartum compared with women who undergo routine GDM management. Study Design A prospective randomized controlled trial of women diagnosed with GDM was conducted. Exclusion criteria were GDM diagnosis ≥ 33 weeks or < 20 weeks. Women were randomly assigned to one of two treatment arms: (1) routine GDM management or (2) an IBEP. Women underwent a 2-hour OGTT at 6 to 12 weeks postpartum. Fisher exact test, t-test, and Wilcoxon rank sum test were used as appropriate. Results Of the 101 women randomized, 49 were assigned to IBEP and 52 received routine GDM management. There was no difference in mean fasting and 2-hour glucose levels on the postpartum 2-hour OGTT between the IBEP and routine management group (88.5 ± 22.9 mg/dL vs. 85.2 ± 13.3 mg/dL, p = 0.49 and 109.8 ± 38.5 mg/dL vs. 109.4 ± 40.8 mg/dL, p = 0.97, respectively). Conclusion GDM women enrolled in a healthy lifestyle intervention program did not demonstrate lower glucose values on the postpartum 2-hour OGTT.
