Objective: To determine the impact of obesity on pregnancies complicated by insulin resistance. Study Design: Secondary analysis of prospective cohort of women with gestational diabetes mellitus (GDM) and type 2 diabetes mellitus (DM). The exclusion criteria were type 1 DM, multiple gestation, fetal anomalies, unknown prepregnancy, and body mass index (BMI). Primary maternal outcome was a composite of any of the following: severe preeclampsia, eclampsia, third- to fourth-degree laceration, readmission, wound infection, or antepartum hospitalization. Primary neonatal outcome was a composite of any of the following: hypoglycemia, preterm delivery, admission to level 3 nursery, oxygen requirement > 6 hours after birth, shoulder dystocia, 5-minute Apgar ≤3, cord pH < 7.0, and cord base excess < -12 mmol/L. Obese women (BMI ≥ 30.0 kg/m
2 ) were compared with nonobese women (BMI < 30.0 kg/m2). Results: Of 356 subjects with DM, 233 (66%) were obese. Obese women were not at further increased risk of the composite maternal outcome (adjusted odds ratio [AOR] = 0.68, 95% confidence interval [CI] = 0.43-1.09), the composite neonatal outcome (AOR = 0.76, 95% CI = 0.48-1.21), or cesarean (58.8 vs. 52.9%, p = 0.28, AOR = 1.47, 95% CI = 0.91-2.39). Conclusion: We did not find evidence that obesity worsened pregnancy outcomes in women with GDMand type 2 DM, suggesting that obese women may not require more stringent antepartum treatment strategies.
