A compartive study on the prevalence of cesarean section and macrosomia of gestational diabetes using the diagnostic criteria of the international association of the diabetes and pregnancy study groups and American diabetes association

Introduction: Cesarean because macrosomia of fetus more happens in cases with gestational diabetes. There are different methods and outcomes for screening of gestational diabetes. In current study comparison between two accepted method of diagnosis of gestational diabetes, American diabetes association (ADA) and international association of diabetes in pregnancy study group (IADPSG) in occurrence of cesarean and macrosomia of fetus was preformed. Materials and methods: All pregnant women between 24-28 weeks of gestation from April 2013 that were referred to Amir Hospital or private office of gynecologist were evaluated. They were evaluated by both ADA and IADPSG tests. If the gestational diabetes was confirmed they were followed until delivery and the prevalence of macrosomia and cesarean were surveyed. Results: Among 236 cases the prevalence of gestational diabetes were 16(7%) and 20(8%) in IADPSG and ADA (P=0.001, kappa=0.219) and the rate of cesarean were 10(62.5%) and 11(55%) in IADPSG and ADA   respectively. The prevalence of fetal macrosomia were 5(31.2%) and 2(10%) in IADPSG and ADA   respectively. Conclusion: The percent of gestational diabetes was more with IADPSG. However, two methods have agreement in diagnosis of diabetes but the agreement was not strong. The prevalence of cesarean and macrosomia was more in ADA. It seems that two methods are not equal in diagnosis and prediction of complications of gestational diabetes
