Materials and Methods
Pregnant women with risk factors for gestational diabetes received 50-g oral glucose screening tests in one of nine community prenatal clinics serving Parkland Hospital in Dallas. Risk factors for immediate screening at any time during pregnancy included glucosuria, a random serum glucose concentration of 130 mg/dL or more (all antepartum women had serum glucose measured on presentation for prenatal care), history of gestational diabetes, concurrent risk factors such as macrosomia or
Results
Between January 1, 1991, and December 31, 1995, 874 women were diagnosed as having class A1 gestational diabetes and singleton cephalic-presenting pregnancies. The main indications for glucose screening in these women included family history (39%), prior delivery of a macrosomic infant (19%), glucosuria (18%), previous gestational diabetes (9%), and a random serum glucose concentration of 130 mg/dL or more (5.7%). The mean (± standard deviation) gestational age at diagnosis was 31.6 ± 5 weeks.
Discussion
We have concluded from this analysis of a large cohort of pregnancies that women with class A1 gestational diabetes have significantly different pregnancy characteristics and outcomes. Women with glucose intolerance are significantly older, larger, and more often Hispanic than those without class A1 gestational diabetes. Pregnancy interventions such as induction of labor were increased because preeclampsia supervened more often in women with class A1 gestational diabetes. Their infants were
