Can a diagnosis of gestational diabetes be an advantage to the outcome of pregnancy?
OBJECTIVES: We examined the obstetric outcomes of 138 treated women with gestational diabetes mellitus (GDM) compared with 144 women who had a 2-hour, 75-g glucose tolerance test result of between 7.0 and 7.9 mmol/L (126 and 142 mg/dL, respectively). METHODS: The subjects for this study were consecutive patients from a universal testing program for GDM during 1993. Gestational diabetes mellitus was diagnosed if the 2-hour plasma glucose level was 8.0 mmol/L (144 mg/dL) or greater after a 75-g glucose load in the fasting state. RESULTS: Treated women with GDM had a macrosomia rate of 8.0%, which was significantly less (P < .02) than the rate of 17.4% in the "normal" women. Treated women with GDM had a 2.2% rate of fetuses weighing less than 2500 g, which was significantly lower (P = .05) than the 6.9% rate for normal women. Overall, insulin therapy was used in 23.2% of the women with GDM, and no insulin-treated woman had either a macrosomic fetus or a fetus weighing less than 2500 g. CO
