Mouratidou N, Malmborg P, Sachs MC, et al. - Researchers tested the assumption that patients with childhood-onset inflammatory bowel disease (IBD) attain a lower adult height than their disease-free peers and siblings in this nationwide population-based study. They identified 4,201 people diagnosed with childhood-onset IBD 1990-2014 (Crohn's disease: n = 1,640; ulcerative colitis: n = 2,201 and IBD-unclassified = 360) in the Swedish National Patient Register. On average, patients with childhood-onset IBD achieve an adult height slightly lower than their healthy peers. In patients with prepubertal onset of disease and in those with a more severe disease course, adult height was more reduced.
