Abstract
Objective: To evaluate pregnancy outcomes among women with pre‐gestational diabetes.Methods: Retrospective analysis of pregnant women with type 1 or type 2 diabetes attending a university hospital in Brazil. Maternal characteristics and pregnancy outcomes were compared among deliveries between May 1, 2005, and December 31, 2010, and between January 1, 2011, and December 31, 2015. Risks were calculated by Poisson regression.Results: In total 220 women were included. Type 1 diabetes was more frequent in 2005–2010 than in 2011–2015, and type 2 diabetes was more frequent in 2011–2015 (P=0.005). History of macrosomia (P=0.011), hypertensive disorders of pregnancy (P=0.015), and pre‐gestational excess weight (body mass index >25 kg/m2; P=0.003) was more frequent in 2011–2015. For women with type 1 diabetes, pre‐gestational weight (P=0.007) and glycated hemoglobin (P=0.026) were higher in 2011–2015. For women with type 2 diabetes, previous hypertensive disorders of pregnancy (P=0.032) were more prevalent and family history of diabetes (P<0.001) less prevalent in 2011–2015. Adverse pregnancy outcomes were similar for type 1 and type 2, and across both periods.Conclusion: Type 2 diabetes became more common over the two time periods and women with type 1 diabetes had higher pre‐gestational weight. Perinatal outcomes were similar.
