Objective:To evaluate the impact of different glucose levels in women with gestational diabetes mellitus on maternal and neonatal outcomes.Methods:Data of 65 pregnant women with GDM admitted in our hospital from January 2001 to October 2006 were reviewed.A total of 46 GDM women had blood glucose levels under control before delivery and the rest 19 GDM women did not.The impact of different glucose levels on maternal and neonatal outcomes were compared between the two groups.Results:In the group with the glucose level uncontrolled
