Abstract
Pregnant women attending the regular prenatal clinic at Los Angeles County (LAC)/Women's Hospital received a 3-h oral glucose tolerance test (GTT). Upper limits for the test are a fasting blood glucose of 100 mg/dl (serum glucose 110 mg/dl), 1 h 170 mg/dl (200 mg/dl), 2 h 130 mg/dl (150 mg/dl), and 3 h 120 mg/dl (130 mg/dl). The incidence of overt diabetes (fasting hyperglycemia) was 3.5% and of Class A diabetic women (abnormal test but normal fasting glucose value) it was 8.8%. The incidence of abnormal tests is greater in obese patients, potential diabetic patients (family history of diabetes or abnormal obstetrical history), and with increasing age. However, it was 3.4% in a group of patients below age 20 yr and without an abnormal medical or obstetrical history. The perinatal mortality in uncomplicated Class A diabetic women is as low as in the general population. Patients with Complicated Class A (previous stillbirth or who develop preeclampsia) and those patients who develop fasting hyperglycemia should have medical and obstetrical surveillance. Twenty-five percent of the infants of Class A diabetic mothers experience some morbidity. Long-term follow-up of mothers with abnormal tests in pregnancy is indicated, since the incidence of subsequent carbohydrate abnormality is 40%. As a screening procedure, pregnant women should have a 2-h serum glucose following the administration of 100 g of a glucose solution. In patients with a value of over 140 mg/dl, a GTT should be performed. In patients with a screening value of less than 140 mg/dl, it should be repeated by 34 wk gestation.
