Can, Guray/0000-0002-6054-9244WOS: 000466334400008PubMed: 29695147Background/Aims: There are only a few epidemiological study about inflammatory bowel disease in the last 10 years in Turkey, especially in Western Blacksea region. In our study, we aimed to identify the changes in the incidence and the prevalence of inflammatory bowel disease in Western Blacksea region at the last 10 years. Methods: Totally 223 patients with inflammatory bowel disease (160 ulcerative colitis, 63 Crohn's disease) were enrolled in the study followed up between 2004 to 2013 years. The epidemiological characteristics of patients were recorded. Results: The prevalences were 12.53/10(5) and 31.83/10(5) for Crohn's disease and ulcerative colitis respectively. Mean annual incidences increased from 0.99/10(5) and 0.45/10(5) for ulcerative colitis and Crohn's disease (2004 to 2005 years) to 4.87/10(5) and 2.09/10(5) for ulcerative colitis and Crohn's disease respectively (2011 to 2013 years). While the prevalence was higher in urban areas in Crohn's disease (12.60/10(5)), it was higher in rural areas in ulcerative colitis (36.17/10(5)). In ulcerative colitis, mean annual incidences were 2.91/10(5) and 2.86/10(5) for urban and rural areas respectively. In Crohn's disease, they were 1.37/10(5) and 1.08/10(5) for urban and rural areas respectively. Conclusions: The incidence of inflammatory bowel disease seems to increase in Western Blacksea region at the last 10 years. This increment is more prevalent in rural areas
