The incidence of inflammatory bowel disease (IBD) in children in the Northern Denmark region increased by 272 percent over four decades (1978–2020)[2]. The NorDIBD pediatric cohort study included 468 children diagnosed with IBD, including 244 with ulcerative colitis and 224 with Crohn's disease[2]. The median age at diagnosis was 15.4 years for both diseases and increased over time[2]. In Crohn's disease, the ileocolic (39.3%) or colonic form (40.2%) was most often diagnosed, while the proportion of patients with a penetrating form of the disease was increasing[2]. In ulcerative colitis, the proportion of children diagnosed with pancolitis has increased[2]. Children who had a first-degree relative with IBD were diagnosed at a younger age[2]. The study provides a basis for future research on long-term outcomes of pediatric IBD[2].
