Incidence, Clinical Presentation and Location at Diagnosis of Pediatric Inflammatory Bowel Disease: A Prospective Population‐Based Study in Northern France (1988‐1999)

Abstract

The incidence of Crohn disease in the children of northern France showed an increasing trend (20%; not significant) during the 12-year period while the incidence of ulcerative colitis remained stable. In the entire population(children and adults)the incidence of Crohn disease increased significantly (+23%; P < 0.001), while the incidence of ulcerative colitis decreased (-17%; P < 0.0001).
