Background Population-based studies comparing the characteristics of paediatric IBD with IBD diagnosed in the adulthood are scarce. The aims of this study were (i) To compare the characteristics of IBD in patients diagnosed during childhood (≤16 years) with those from patients diagnosed in adulthood; (ii) to compare the incidence rate of initiation of immunosuppressants, biologic agents and surgery between both groups; and (iii) to evaluate the impact of the age at diagnosis on the initiation of immunosuppressants, biological agents and surgery. Methods IBD patients from the ENEIDA registry—a large prospectively maintained Spanish database promoted by the Spanish Working Group in Crohn’s and Colitis (GETECCU), were included. In order to minimise the heterogeneity in the management of IBD patients, the inclusion was limited to those diagnosed after 1998, when the fist biological agent was approved for IBD in Europe. Patients diagnosed at ≤16 years comprised the paediatric cohort (PC), and those diagnosed >16 years were the adult cohort (AC). The cumulative incidences of immunosuppressive therapy, biological therapy and surgery, were estimated using Kaplan–Meier curves, which were compared by the log-rank test. Cox-regression analysis was performed to identify potential predictive factors to receive immunosuppressants, biological agents or surgery. Results From 35925 patients, there were 1630 paediatric cases (4.5%) and from them, 56 (3.4%) were very-early-onset IBD (<6 years). Median follow-up was 91 months in the PC and 72 months in the AC. The proportion of Crohn’s disease (CD), ileocolonic involvement and inflammatory behaviour at diagnosis was higher in the PC (Table 1).

However, paediatric IBD was not associated with higher risk of surgery (Table 2).

      Methods
      IBD patients from the ENEIDA registry—a large prospectively maintained Spanish database promoted by the Spanish Working Group in Crohn’s and Colitis (GETECCU), were included. In order to minimise the heterogeneity in the management of IBD patients, the inclusion was limited to those diagnosed after 1998, when the fist biological agent was approved for IBD in Europe. Patients diagnosed at ≤16 years comprised the paediatric cohort (PC), and those diagnosed \&gt;16 years were the adult cohort (AC). The cumulative incidences of immunosuppressive therapy, biological therapy and surgery, were estimated using Kaplan–Meier curves, which were compared by the log-rank test. Cox-regression analysis was performed to identify potential predictive factors to receive immunosuppressants, biological agents or surgery.
    
    
      Results
      From 35925 patients, there were 1630 paediatric cases (4.5\%) and from them, 56 (3.4\%) were very-early-onset IBD (\&lt;6 years). Median follow-up was 91 months in the PC and 72 months in the AC. The proportion of Crohn’s disease (CD), ileocolonic involvement and inflammatory behaviour at diagnosis was higher in the PC (Table 1).

      Conclusions
      Paediatric IBD has differential characteristics in comparison with adult IBD. In addition, paediatric IBD seems to be associated with higher use of immunosuppressant and biologics during follow-up. Nevertheless, paediatric IBD is not associated with higher risk of surgery.},
