[Crohn's disease in the adult population in Slovakia].

The requirement of preparing a fundamental epidemiological study concerning the incidence of Crohn's disease in Slovakia became very important after the splitting of Czecho-Slovakia. The authors in cooperation with the regional gastroenterologists present the study concerning the incidence of this inflammatory bowel disease in the Slovak Republic up to 30th April 1994. The multidimensional Kruskal-Wallis test for analyzing statistical differences in incidence of Crohn's disease according to age, sex, and regions was used. Cluster analysis was used for investigation of the regional differences. This study has shown that there is 6.75 cases of Crohn's disease per 100 000 inhabitants in Slovakia. There are no differences in incidence rate of Crohn's disease between the regions. There are differences between the districts: some of districts have both, absolutely and relatively high number of cases, and in another districts, young people are more involved in the analysed disease. The highest age specific incidence rate of Crohn's disease was between 30-49 years. (Tab. 1, Fig. 7, Ref. 14.)
