ATLANTIC-DIP: Raised Maternal Body Mass Index (BMI) Adversely Affects Maternal and Fetal Outcomes in Glucose-Tolerant Women According to International Association of Diabetes and Pregnancy Study Groups (IADPSG) Criteria

Context: Raised maternal body mass index (BMI) in association with hyperglycemia is associated with adverse pregnancy outcome. The contribution of raised BMI as an independent risk factor for adverse pregnancy outcome is of growing concern and increasing prevalence. Objective: The aim of this study was to investigate the effects of raised maternal BMI on pregnancy outcome in glucose-tolerant women using the International Association of Diabetes and Pregnancy Study Groups criteria. Participants and Setting: We studied a cohort of glucose-tolerant, pregnant women (n = 3656) who were attending antenatal obstetric clinics and were recruited to a universal screening program for gestational diabetes under the ATLANTIC-DIP partnership. Design: We conducted a prospective observational study of pregnancy outcome. Maternal outcomes include glucose, delivery mode, pregnancy-induced hypertension, preeclampsia, antepartum hemorrhage, and postpartum hemorrhage. Fetal outcomes included birthweight, congenital malformati...
