Abstract:

Objectives: The aim of this study was to describe the incidence and prevalence of inflammatory bowel disease (IBD) in children <17 years of age in 30 years from 1978 to 2007.

Methods: From January 1, 1978, to December 31, 2007, the sex- and age-adjusted annual incidence and prevalence of pediatric IBD per 100,000 population were calculated based on the pediatric IBD database of the only pediatric tertiary center in the province. The annual health statistics records for the Province of Manitoba were used to calculate population estimates for the participants. To ensure validity of data, the University of Manitoba IBD Epidemiology Database was analyzed for patients <17 years of age from 1989 to 2000.

Results: The sex- and age-adjusted incidence of pediatric Crohn disease has increased from 1.2/100,000 in 1978 to 4.68/100,000 in 2007 (P < 0.001). For ulcerative colitis, the incidence has increased from 0.47/100,000 in 1978 to 1.64/100,000 in 2007 (P < 0.001). During the same time period, the prevalence of Crohn disease has increased from 3.1 to 18.9/100,000 (P < 0.001) and from 0.7 to 12.7/100,000 for ulcerative colitis (P < 0.001). During the last 5 years of the study the average annual incidence of IBD in urban patients was 8.69/100,000 as compared with 4.75/100,000 for rural patients (P < 0.001).

Conclusions: The incidence and prevalence of pediatric IBD are increasing. The majority of patients were residents of urban Manitoba, confirming the important role of environmental factors in the etiopathogenesis of IBD.
