The research on reproductive women with inflammatory bowel disease (IBD) has focused on short-term outcomes and the studies on the long-term health outcomes of the children of parents with IBD are scarce. Therefore, there is a gap in understanding the influence of parental IBD on long-term outcomes especially in growth and development of their children. The objective of this study is to assess the long-term influence of maternal IBD on disease, growth and development of their offspring.
