Specific phenotypes may drive an increased incidence of pediatric inflammatory bowel disease in South-Eastern Norway.

ABSTRACT:

Objectives

Pediatric inflammatory bowel disease (PIBD) incidence has increased in recent decades but may be stabilizing, prompting exploration of incidence changes, disease distribution, and severity.

Methods

From 2017 to 2019, patients under 18 years with PIBD symptoms were recruited from nine hospitals in South-Eastern Norway for Inflammatory Bowel Disease in South-Eastern Norway III (IBSEN III), a population-based inception cohort study. The primary outcome was a diagnosis of any PIBD subtype as defined by revised Porto criteria. Paris classification system defined disease phenotypes, and descriptions of covariates were gathered from patients in IBSEN III.

Results

We identified 324 PIBD patients, with 216 consenting to the IBSEN III study. The crude incidence rate
