Regression From Early GDM to Normal Glucose Tolerance and Adverse Pregnancy Outcomes in the Treatment of Booking Gestational Diabetes Mellitus Study

Diabetes CarePublished Secondary analysis of the Treatment of Booking Gestational Diabetes Mellitus randomised controlled trial

Authors' conclusion

Women with early GDM but normal OGTT at 24-28 weeks' gestation had pregnancy outcomes that were similar to those of individuals without GDM. Identifying early GDM likely to regress would allow treatment to be avoided.

Study context

Population
Women at <20 weeks' gestation with GDM risk factors recruited for an RCT of early GDM treatment; treated early GDM and late GDM (WHO 2013 criteria) excluded
Participants
2,218 / 121 / 254
Comparison
GDM-Regression vs No-GDM vs GDM-Maintained
  • No-GDMn = 2,218reference
  • GDM-Regressionn = 121
  • GDM-Maintainedn = 254
Primary endpoint
Pregnancy outcomes

Primary result

As reported in the abstract

Pregnancy complications
  • Adjusted incidences of pregnancy complications similar between GDM-Regression and No-GDM
  • GDM-Regression risk factor profiles and oral glucose tolerance test (OGTT) results generally fell between No-GDM and GDM-Maintained
  • Logistic regression
