Background
Data regarding the prevalence of inflammatory bowel disease (IBD) are scarce in Brazil. The aim of this study was to determine the prevalence of IBD and to analyse the demographical, clinical phenotipes of these cases in a tertiary IBD Unity in Southeast Brazil.
Methods
Retrospective analysis from the adult population‐based IBD cohort of Clinical Hospital of Ribeirão Preto Medical School, University of São Paulo, Brazil, between 2014 and 2018. Medical records consisted in age, gender, occupation, disease (Crohn’s disease [CD]; ulcerative colitis [UC]), disease location, moderate-to-severe feature, previous surgeries, treatments, and biological therapy.
Results
Of 579 patients, 325 had CD and 254 had UC. Fifty-three (53%) were females. Mean age at diagnosis was 32.4 years. Eighty-two per cent of patients were moderate to severe. The mean time of disease was 159 months (13.25 years). Two hundred and two patients (n = 272) are in the use of biological therapy. The distribution of CD cases in relation to location was: L3 (54.8%), L1 (29.1%), L2 (15.2%), and L4 (0.9%) and the behaviour was; B1 (26.3%), B2 (12.7%), B3 (20.1%), B3P (31.9%), B2 / B3 (4.6%) and B2 / B3P (4.3%).In the UC the distribution of the cases in relation to the location was; E3 (53.1%), E2 (26%) and E1 (20.9%). Table 1 summarises the results in UC and CD. Female was more frequently in UC (60.6% vs. 47.4%, p = 0.0019; OR = 0.5848; CI 95%: 0.419–0.815). Biological therapy was more frequently in CD (64.3% vs. 26.0%, p < 0.0001; OR = 5.064; C1 95%: 3.531–7.262). Previous surgeries (59.1% vs. 19.7%, p < 0.0001; OR = 5.89; C1 95%: 4.027–8.615) and deaths (2.8% vs. 0%) were more common in CD.

Conclusions
There was a predominance of patients with CD in our IBD Unit. Most of UC patients were female. CD was associated with higher risk of surgery, biological therapy and death.1,2
