Abstract

Introduction The incidence of paediatric inflammatory bowel disease (IBD) has risen significantly across Europe in the last 20 years, although our own data had suggested that this had plateaued by 2004. We have now studied the data from the same area over the last decade and compared them with our previous studies (1983–2003).

Methods All cases of IBD <16 years of age residing in a defined location within our region were prospectively recorded from January 2004 to March 2014. The incidence, age, gender and disease type were analysed and compared to our data from 1983–2003 from the same region.

Results See Table 1. Between 2004 and 2014, there were 57 new patients compared to 39 (1996–2003) and 28 (1983–1993). The overall incidence of IBD was 5.9 per 100,000 per year, Crohn’s disease (CD) 3.7 per 100,000 per year and Ulcerative colitis (UC) 2.07 per 100,000 per year compared with 5.4 per 100,000 per year for 1996 to 2003. There was no statistically significant difference between the two time periods (p value of 0.675). The median age at diagnosis remains at 12 years with a male to female ratioof 1.7:1.

Conclusion The incidence of paediatric IBD in a defined geographical area within our region has remained similar for more than 15 years with a slight increase in the incidence of UC, suggesting that the previous exponential rise in incidence has reached a stable state.
