# Adult Rome IV Disorders of Gut–Brain Interaction in a Pediatric Population

## TL;DR

This study finds that adult gut-brain interaction disorders can appear in children and are linked to depression and school issues.

## Contribution

The study identifies adult DGBIs in children using Rome IV criteria and highlights their association with psychosocial factors.

## Key findings

- 5.8% of the pediatric population met adult DGBI criteria according to Rome IV.
- Proctalgia fugax was the most common disorder identified.
- Depression and school/social absenteeism were strongly associated with DGBIs.

## Abstract

Background: Disorders of the gut–brain interaction (DGBIs) constitute a group of functional conditions widely described in adults; however, some of these have not been included in pediatric Rome criteria, despite the fact that they may manifest during childhood. Early identification of these conditions is relevant due to their clinical/psychosocial impact as well as their effect on quality of life. The aim was to determine the prevalence and associated factors of some DGBIs described in adults according to the Rome IV criteria in pediatric population. Methods: An observational/prospective/cross-sectional study was conducted in toddlers, school-aged children, and adolescents from three Colombian cities. The adapted Questionnaire for Pediatric Gastrointestinal Symptoms Rome IV (QPGS-IV) using adult criteria was applied, along with quality-of-life scales and PROMIS for anxiety/depression. Descriptive uni/bivariate analyses were performed as well as a multivariate logistic regression model. Results: A total of 704 participants were included (13.7 ± 2.8 years old). The prevalence of DGBIs described in adults according to QPGS-IV was 5.8%, with proctalgia fugax being the most frequent. In the bivariate analysis, race, school/social absenteeism, depressive traits, and impaired quality of life were significantly associated. In the multivariate model depressive traits (OR = 4.08; 95%CI = 1.82–9.12; p = 0.001), school (OR = 2.51; 95%CI = 1.06–5.98; p = 0.036), and social absenteeism (OR = 4.04; 95%CI = 1.70–9.62; p = 0.002) were the factors independently associated. Conclusions: These adult DGBIs, according to the QPGS-IV, can occur in pediatric populations and are closely related to psycho-emotional and functional factors. These are mainly associated with depression and school/social absenteeism, supporting the need for a biopsychosocial approach and a revision of the pediatric diagnostic criteria.
