Effect of borderline glucose intolerance on fetal maternal outcome

Purpose of investigation: The aim of this study was to compare the maternal and neonatal adverse outcomes in pregnant women whose glucose challenge test (GCT) results were below 130 mg/dl and between 130-139 mg/dl. Materials and Methods: Three hundred and six women with 50-gram GCT results of 130-139 mg/dl and 305 women with 50-gram GCT results of < 130 mg/dl were recruited. Results: Higher pre-postpartum hemoglobin difference (p = 0.001), longer postpartum hospitalisation time (p = 0.001), and increased cesarean section rates (p = 0.01) were reported in the study group. There were no differences between two groups in rates of preeclampsia, polyhydramnios, ablatio placenta, and chorioamnionitis. Conclusions: The authors suggest that a GCT result between 130-139 mg/dl is not associated with higher maternal and neonatal morbidity. Results do not support a conclusion of high maternal and neonatal morbidity in the study group and give an impression that the 140 mg/dl threshold value is adequate for screening.
