Pregnant Women with Inflammatory Bowel Disease (IBD) are More Likely to be Vitamin D Insufficient than Pregnant Women without IBD (Master's thesis, University of Calgary, Calgary, Canada). Retrieved from https://prism.ucalgary.ca. doi:10.11575/PRISM/27413http://hdl.handle.net/11023/3725Vitamin D insufficiency is associated with adverse pregnancy outcomes. Since individuals with inflammatory bowel disease (IBD) are at risk for vitamin D insufficiency, studying vitamin D status in women with IBD is of importance as the peak incidence of IBD occurs between 18-35 years of age. Currently there is no literature that evaluates vitamin D status in pregnant women with IBD. Therefore, the prevalence of vitamin D insufficiency in pregnant women with IBD was assessed. This study demonstrated that pregnant women with IBD are more likely to be vitamin D insufficient than those without IBD. Further, the current recommended daily dosage of vitamin D supplements for all pregnant women is not appropriate to achieve vitamin D sufficiency, particularly for those with IBD. Appropriate clinical practice guidelines for vitamin D supplementation during pregnancy are needed for optimal prenatal care of pregnant women with IBD to improve their pregnancy outcomes.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
