Abstract
OBJECTIVE
To evaluate the clinical outcomes of pregnancies showing one abnormal glucose tolerance test value. Method: We performed 50 gm glucose challenge test in 5,019 pregnant women at 24-28 weeks of gestation. In 1,170 women with plasma glucose levels over 130 mg/dL, 100 gm oral glucose tolerance tests (OGTTs) were performed at 28-32 weeks of gestation. In the 888 cases who were followed up, according to the National Diabetes Data Group (NDDG) criteria, 122 cases with one abnormal 100 gm OGTT value were divided into three groups (groups 1, 2, 3 : abnormal value after 1, 2, 3 hours, respectively). These were compared with 577 cases (control group) with normal 100 gm OGTT value, retrospectively. Result: The incidence of one abnormal glucose tolerance test value was 2.6%, and there were no cases where the fasting plasma glucose level only was elevated. The incidence (control, group 1, group 2, group 3 : 19.4%, 43.8%, 25.7%, 29.6%) of poor maternal outcomes which contain any one of preeclampsia, hydramnios, cesarean delivery for cephalopelvic disproportion or failure to progress or fetal distress was highest in group 1 (p=0.025). The incidence (15.8%, 43.1%, 14.3%, 21.1%) of poor perinatal outcomes which contain any one of fetal distress, Apgar score of 5 minute < 7, hypoglycemia, respiratory distress syndrome, small for gestational age, perinatal death was also highest in group 1 (p=0.009). Logistic regression analysis for poor maternal outcomes showed odds ratio of 2.83 (95% confidence interval 1.02-7.87) in group 1 and 2.08 (95% confidence interval 1.22-3.55) in group 3, and for poor perinatal outcomes odds ratio of 4.24 (95% confidence interval 1.02-17.52) in group 1 and 3.30 (95% confidence interval 1.45- 7.48) in group 3. CONCLUSION: Pregnancies complicated with one abnormal glucose tolerance test value, particularly the group showing abnormal glucose tolerance test value after 1 or 3 hour exhibited adverse maternal and perinatal outcomes.
Key Words: One abnormal glucose tolerance test value, Perinatal outcomes
