Epidemiological Features of Ulcerative Colitis in Trakya, Turkey

Abstract

To determine the epidemiological features of ulcerative colitis in the Trakya region of Turkey, southeast Europe, we conducted a descriptive, cross-sectional, hospital-based study. All subjects were followed, and age, sex, place of residence, family history, educational status, tobacco consumption and use of oral contraceptives were recorded. The study included 49 cases of ulcerative colitis. The incidence of the disease was 0.59 per 100,000 in 1998, 0.89 per 100,000 in 1999, 0.89 per 100,000 in 2000 and 0.69 per 100,000 in 2001. The overall prevalence of the disease was 4.9 per 100,000; it was 2.18 per 100,000 in rural areas and 5.87 per 100,000 in urban areas. As in the Mediterranean countries, both the incidence and the prevalence of ulcerative colitis were found to be low. The incidence was significantly higher in urban areas than in rural areas.
