Several studies have demonstrated that even one abnormal glucose value of diagnostic OGTT was associated with unfavorable feto-maternal outcomes of pregnancy such as macrosomia, preeclampsia, eclampsia, and cesarean delivery.
One abnormal value of OGTT might reflect some degree of carbohydrate intolerance that might be related to increased risk for maternal and neonatal morbidities.
However, no study has demonstrated the risk of developing GDM later in their pregnancy among this group of women. Therefore, the present study was aimed at determining the incidence of GDM among those who had one abnormal OGTT value.
In addition, pregnancy outcomes were evaluated in those with normal and abnormal tests.
