Determining the need for insulin therapy is critical for controlling the glycemic level in GDM patients. The study contains two major purposes: 1) to identify the potential predictors for the need of insulin therapy in GDM patients; 2) to identify the factors that are related to the onset of postpartum IGT.Materials and Methods: Here, we performed a retrospective study on 112 GDM patients in China to identify the significant predictors for the need of insulin therapy and onset of postpartum IGT in patients with GDM.Results: Age and gestational weeks at GDM diagnosis, pregestational BMI, family history of diabetes mellitus (DM), plasma glucose levels assessed by 75-g OGTT at both the 1-hour and 2-hour time points (PG-1h and PG-2h) and HbA1c level were all significantly different between the patients that received insulin therapy and those did not. During postpartum, family history of DM, PG-1h PG-2h and HbA1c level were found to be significantly different between the patients with normal glucose tolerance and those with IGT.Conclusion: Our results reveal a number of factors that are closely associated with the need of insulin therapy and onset of postpartum IGT, especially the PG-1h and PG-2h levels. These findings will provide valuable indications on selection of treatment strategy for GDM and GDM-induced postpartum IGT.Keywords: insulin, glucose, diabetes, pregnancy, postpartum
