Description:Background
Studies describing the incidence of Crohn’s disease (CD) and ulcerative colitis (UC) are uncommon in the United States (US). We sought to determine the incidence of CD and UC in the state of Rhode Island (RI).
Methods
The Ocean State Crohn’s and Colitis Area Registry (OSCCAR) is a state-based inception cohort of patients newly diagnosed with IBD in RI. To confirm a diagnosis of CD, UC or IBD unclassified (IBDU), the NIDDK IBD Genetics Consortium criteria were applied in a review of medical records from gastroenterology practices located in the state of RI and adjacent to the RI border in Massachusetts and Connecticut. Utilizing population-based data, we determined the statewide incidence of IBD in RI in 2008–2010.
Results
A total of 971 RI residents were diagnosed with IBD, including 444 with CD, 486 with UC and 41 with IBDU in 2008–2010. The overall age- and sex-adjusted IBD incidence was 30.2 (95% CI, 28.3–32.1) per 100,000 persons in this time frame with 13.9, 15.1 and 1.3 per 100,000 diagnosed with CD, UC and IBDU, respectively. Of the total incident cases in RI, 30% (n=291) were enrolled in OSCCAR for follow up.
Conclusion
The incidence of IBD in RI is higher than that previously reported by other population-based cohorts in the US. Prospective follow up of individuals enrolled in the community-based OSCCAR cohort is ongoing.
