BACKGROUND AND AIMS: The incidence of inflammatory bowel disease (IBD) among women is highest during their reproductive years and current estimates suggest that the rate of conception is low in female IBD patients. The aim of our study was to assess the burden of adverse maternal and perinatal outcomes among female IBD patients.

METHODS: Using the national inpatient sample database from 2016 to 2018, we recruited all female patients above the age of 15 years admitted with a primary diagnosis of pregnancy and a secondary diagnosis of IBD. We adjusted our results for hospital and patient level variables including age, race, socioeconomic status, hypertension, diabetes mellitus, obesity, smoking, hyperlipidemia, alcohol use, and malnutrition. Multivariable regression analysis was used for analysis.

RESULTS: Pregnant women with IBD had greater odds of gestational diabetes (adjusted odds ratio [AOR] 1.55, 95% confidence interval [CI] 1.04-2.3, p 0.02), hypertensive complications (AOR 1.35, 95% CI 1.06-1.72, p 0.01), and pre-term delivery (AOR, 1.41 95% CI 1.13-1.76, p 0.003). Pregnancies with co-existent IBD were associated with fetal growth restriction (AOR 1.27, 95% CI 1-1.63, p 0.04) and fetal death (AOR 3.21, 95% CI 1.72-6.00, p < 0.01). Odds of experiencing postpartum hemorrhage or large for gestational age infant were comparable to general population. Crohn's disease was independently associated with increased odds of worse maternal and fetal outcome. IBD patients had increased mean length of stay by 0.14 days and increased mean hospital charges of $2741.

CONCLUSIONS: Women with IBD had greater likelihood of poor maternal and fetal outcomes and increased hospital resource utilization.
