Incidence of gestational diabetes: effects of race.
A total of 2,435 pregnant women underwent glucose screening during the late second trimester or early third trimester. Of those screens, 548 (22.5%) were abnormal; from these, 154 abnormal glucose tolerance tests were recorded. This gave an overall 6.3% incidence of gestational diabetes at our institution. Eighty-two of the abnormal glucose tolerance tests were in Hispanic females, but this was not significantly higher than in other racial groups. Patients with a negative glucose tolerance test after a positive diabetic screen and obese gravidas had an 11.3% incidence of macrosomia. Of all the macrosomic infants (greater than 4,000 g) 38% of mothers weighed 200 lb (90 kg) or more.
