Dietary Beliefs and Habits in Pediatric IBD: Insights from a Single-Center Survey

Background: Patients with inflammatory bowel disease (IBD) often follow restrictive diets. Data on dietary habits and beliefs in pediatric IBD are scarce. Our aim was to assess dietary habits, beliefs, and knowledge regarding nutrition and IBD among children with IBD. Method: In this single-center, cross-sectional study, pediatric patients aged 12-18 years with IBD completed a non-scoring, 25-item questionnaire assessing general dietary habits, beliefs about diet's role in IBD pathogenesis and treatment, food avoidance, and food-related experiences since diagnosis. Results: We included 72 IBD patients (mean age [SD]: 15.2 [2.3] years; 41 (57%) were male, 32 (45%) had Crohn's disease (CD)). Almost half of the participants did not believe that eating habits contributed to the pathogenesis of IBD. One-third of patients considered diet to be more important than medication. Approximately two-thirds changed their eating habits after diagnosis, regardless of disease type (χ²: 0.70, p = 0.40), or induction therapy (nutritional vs. non-nutritional, χ²: 0.02, p = 0.88). At least one food was avoided by 65% of the participants. Conclusions: Most children have changed their dietary habits and avoided one or more food groups. The type of induction therapy did not relate to the knowledge and dietary beliefs after induction. Our findings suggest that repeated education and dietary counseling should be an integral part of the management of pediatric IBD.
