The Incidence of Inflammatory Bowel Disease in the Paediatric Population in the District of Lower Silesia, Poland

The incidence of IBD has been rising over the last decades. The trend applies not only to well-developed countries but also to the regions with limited number of cases so far, e.g., Asia or Middle East. Aim: The aim of the study was to determine the incidence of paediatric IBD in the district of Lower Silesia, Poland, between 2016 and 2018. Methods: The number of newly diagnosed IBD per 100,000 children, living in the region, was calculated. The characteristics of the group were established. Results: There were 81 cases of paediatric IBD diagnosed between the 1st of January 2016 and 31st of December 2018. The diagnosis of ulcerative colitis (UC) was made for 42 children. In the same period of time 39 cases of Crohn disease (CD) were recognised. The incidences were calculated as 2.57 for UC, and 2.38 for CD. The total incidence of IBD between 2016 and 2018 was 4.96/100,000/year which is rise in the last 20 years. Conclusion: An increase in incidence of IBD in the district of Lower Silesia has been observed
