ABSTRACT
Gestational diabetes mellitus (GDM) is defined as glucose intolerance first recognized during pregnancy (1). This definition applies regardless of treatment regimens and does not distinguish between those unrecognized cases of diabetes that may have preceded pregnancy. GDM occurs in 0.5% to 12.3% of pregnancies depending on the criteria used and the population being tested (2,3). In the United States, prevalence rates are higher in African, Hispanic, Native American, and Asian women than in white women (4-6).
