Trail IBD Summary 2018

This study was conducted by the BC Center for Disease Control (BC CDC), as an update to the 2013 study of inflammatory bowel disease (IBD) in Trail. This update found that the conclusion of the 2013 study, i.e., that the occurrence of IBD overall was higher in Trail, was largely due to the very general way in which inflammatory bowel diseases had been categorized. The 2018 study used more specific diagnostic categories to look at the two key forms of IBD of main concern – Crohn’s disease and ulcerative colitis. This update found that while rates of ulcerative colitis were the same for Trail and Interior Health, Crohn’s disease occurred at a higher rate in Trail from 2010-2015, and with an earlier onset of the disease. The BC CDC committed to undertake further analysis of the data on IBD in Trail.
