Inflammatory bowel disease and preterm delivery

The association between inflammatory bowel disease (IBD) and preterm delivery is controversial. Study size, quality, and design have been inconsistent, making it difficult to assess the relationship between IBD and preterm delivery. Utilizing a systematic search of Pubmed for all relevant literature, this review seeks to clarify the correlation between IBD and preterm delivery and to assess the impact of disease activity and medication usage on this outcome. The available evidence is inadequate to make any robust claims about the association between IBD and preterm delivery. IBD in pregnant women may represent a risk for preterm delivery, and it is probable that IBD activity augments this risk. Many of the medications used to treat IBD also have a correlation with preterm delivery. While an association between IBD and preterm delivery may exist, further well-designed prospective studies are necessary to determine how the course and management of disease may impact this outcome.
