Incidence has increased from 9.5/100,000 in 1994 to 11.4/100,000 in 2005 (Figure 10). Interestingly, most of this increase has occurred since 2001. This may be related to an undetermined environmental factor or due to patterns of migration. Incidence is increasing significantly in children aged 0-4 years and 5-9 years, but rates are stable in 10-14 and 15-17 year-olds. This means that IBD is increasing most rapidly in young children, those below 10 years of age – a troubling finding. The higher incidence in older female children shows that the adult pattern emerges after puberty -- when more females will be diagnosed with IBD and eventually outnumber males.
