Abstract

Objective: To identify risk factors for adverse pregnancy outcome in women with inflammatory bowel disease (IBD) and to assess the effect of maternal pre-pregnancy weight and weight gain during pregnancy on pregnancy outcome. Methods: A retrospective, matched control study of all gravid women with IBD treated in a single tertiary center. Data were compared with healthy controls matched to by age, parity and pre-pregnancy BMI in a 3:1 ratio. Results: Overall, 300 women were enrolled, 75 women in the study group (28 with ulcerative colitis and 47 with Crohn's disease) and 225 in the control group. The rates of preterm delivery and small for gestational age were higher in the study group (13.3 vs. 5.3% p = 0.02 and 6.7 vs. 0.9%, p = 0.004). The rate of cesarean section (36 vs. 19.1%; p = 0.002), NICU admission (10.7 vs. 4.0%, p = 0.03) and low 5-Min Apgar (4.0 vs. 0.4%, p = 0.02) were increased in the study group. Disease activity within 3 months of conception [OR 8.4 (1.316.3)] and maternal weight gain of less than 12 kg. [OR 3.6 (1.112.2)] were associated with adverse pregnancy outcome. Conclusion: Active disease at conception and inappropriate weight gain during pregnancy are associated with increased adverse pregnancy outcome in patients with IBD.
