Epidemiologic features of ınflammatory bowel disease in Western Blacksea region of Turkey for the last 10 years: retrospective cohort study

Abstract

Background/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 inf lammatory 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 12.53/105 and 31.83/105 for Crohn’s disease and ulcerative colitis respectively. Mean annual incidences increased from 0.99/105 and 0.45/105 for ulcerative colitis and Crohn’s disease (2004 to 2005 years) to 4.87/105 and 2.09/105 for ulcerative colitis and Crohn’s disease respectively (2011 to 2013 years). While the prevalence was higher in urban areas in Crohn’s disease (12.60/105), it was higher in rural areas in ulcerative colitis (36.17/105). In ulcerative colitis, mean annual incidences were 2.91/105 and 2.86/105 for urban and rural areas respectively. In Crohn’s disease, they were 1.37/105 and 1.08/105 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.
