“…Despite some variability of data across epidemiological studies due to regional differences and methods of diagnosis, the incidence rates of ulcerative colitis (UC) in the elderly are higher than those for Crohn's disease (CD) and range from 1 to 20/100,000 for UC in Europe and in the United States [6] compared to 1 to 10/100,000 for CD in Europe [1,6]. A recently published National cohort study in Sweden has reported that 23% of subjects with diagnosed IBD had a first diagnosis of IBD at age ≥60 years and that in elderly patients, the IBD incident rate was 35/100,000 person/years (male: 37; female: 33) and was 10/100,000 for CD, 19/100,000 for UC, and 5/100,000 for IBD unclassified [11].…”
