ABSTRACT

Background:

The epidemiology of inflammatory bowel diseases (IBD) varies between different regions of Brazil. This cross-sectional study examined the epidemiological characteristics of IBD in the Southern Brazilian state of Paraná.

Methods:

We included patients with IBD (n=6.748) selected across 11,468,818 population of Paraná. All patients had a known diagnosis of either Crohn's disease (CD) or ulcerative colitis (UC) and had started treatment through the Government Program of the Brazilian Unified Health System (2010-2019). The primary outcomes were changes in the incidence and prevalence rates of IBD.

Results:

The study population consisted of 4.931 (73.1%) patients with UC and 1.817 (26.9%) patients with CD. In participants aged 11-30 years, CD was more common, while in participants aged 40-80 years, UC predominated. UC was more common in female compared to male patients, with a similar incidence between the sexes evident for CD. In 2010, the incidence of IBD was 2.00/100,00 population; this increased to 13.77/100,000 population by 2019. The highest concentration of IBD patients was found in the eastern macro-region of Paraná, which includes the 2nd Health Regional of Curitiba, where the capital of the state is located.

Conclusion:

This is the first study to describe the epidemiological characteristics of IBD in the state of Paraná and showed an increase in its incidence and prevalence. We also identified that IBD was concentrated in the eastern macro-region of this Brazilian state.
