JD Lewis et al. Gastroenterology 2023 Nov;165(5):1197-1205.e2. doi: 10.1053/j.gastro.2023.07.003. Incidence, Prevalence, and Racial and Ethnic Distribution of Inflammatory Bowel Disease in the United States
This “INPUT” (INcidence, Prevalence, Treatment and OUTome in Patients with IBD) study used 4 different data sets to provide “the clearest depiction to date of IBD [epidemiology] in the U.S.
Key findings:
- The age-, sex- and insurance-standardized prevalence of IBD was 721 per 100,000 population. This equates to estimated 2.39 million Americans with IBD.
- Sub-category prevalence: the prevalence of IBD per 100,000 population was 812 in White, 504 in Black, 403 in Asian, and 458 in Hispanic Americans.
My take: The prevalence of IBD continues to increase and the U.S. has one of the highest rates in the world.
