Nishikawa T, et al. - Researchers examined the predictors of the need for insulin therapy in gestational diabetes mellitus (GDM) patients. Furthermore, they analyzed the predictors of postpartum impaired glucose tolerance (IGT). Findings illustrated gestational weeks at GDM diagnosis and history of pregnancy were considerably lower, and pregestational body mass index, family history of diabetes mellitus, 1- and 2-h glucose levels in a 75 g oral glucose tolerance test (OGTT), the number of abnormal values in a 75 g OGTT, and glycated hemoglobin were significantly higher in participants receiving insulin therapy. It was inferred that antepartum 1-h glucose levels in a 75 g OGTT presented as a predictor of the need for insulin therapy in pregnancy and postpartum IGT.
