RESEARCH DESIGN AND METHODSIncluded were patients with singleton gestation enrolled in an outpatient GDM management program for at least 7 days who delivered at term. Blood glucose control was defined as an average fasting blood glucose of <95 mg/dl, 1-h postprandial of <140 mg/dl, or 2-h postprandial of <120 mg/dl. Data were compared between patients with optimal blood glucose control (n = 2,030) and those with suboptimal blood glucose control (n = 1,188). The primary study outcome was a composite variable consisting of macrosomia, large-for-gestational-age, hypoglycemia, jaundice, or stillbirth. RESULTSOver one-third of infants in the poorly controlled group were positive for at least one factor comprising the composite variable compared with 24% from the controlled group (P < 0.001). CONCLUSIONSSuboptimal glycemic control in women with GDM is associated with adverse neonatal outcome. Careful monitoring of blood glucose levels and initiation of appropriate treatment are essential in the care of women with GDM.
