Implication

Prospective multicenter study finds higher inflammatory bowel disease incidence in northern versus southern Europe, suggesting a narrowing geographic gradient across European populations.

Key Points

To ascertain and compare the prospective incidence of inflammatory bowel disease, including ulcerative colitis and Crohn's disease, across northern and southern European centres.
Prospectively identified all newly diagnosed cases of inflammatory bowel disease across 20 European centres between October 1, 1991, and September 30, 1993, using standardized case ascertainment and diagnostic criteria.
Identified N=2,201 patients aged 15 years or older (1,379 ulcerative colitis, 706 Crohn's disease, and 116 indeterminate colitis) and calculated age- and sex-standardized incidence rates per 100,000 for ages 15–64.
Overall standardized incidence per 100,000 persons aged 15–64 was 10.4 (95% CI, 7.6 to 13.1) for ulcerative colitis and 5.6 (95% CI, 2.8 to 8.3) for Crohn's disease.
Incidence was significantly higher in northern versus southern centres for ulcerative colitis (rate ratio = 1.4, 95% CI, 1.2 to 1.5) and Crohn's disease (rate ratio = 1.8, 95% CI, 1.5 to 2.1).
Age-specific incidence of ulcerative colitis declined with advancing age in women but remained stable in men.
