Celiac Disease Management in School Environments: An Interdisciplinary Narrative Review of Operational, Psychosocial, and Nutritional Barriers

Background: Pediatric celiac disease (CD) prevalence is rising, estimated at 2% to 3% in select screening cohorts. Affected children face significant environmental, psychosocial, and nutritional barriers within institutional school settings. Methods: This narrative review synthesizes published clinical trials, cohort studies, and food science data to examine infrastructure vulnerabilities and care gaps within educational environments. Results: High-volume school kitchens present potential mechanical cross-contact risks via convection currents and shared equipment. Standard alcohol hand sanitizers demonstrate negligible mechanical or chemical efficacy against inert gliadin proteins, suggesting the need for surfactant-based washing protocols. In classrooms, tactile wheat-based materials introduce non-dietary ingestion pathways. These collective environmental challenges may contribute to social exclusion, peer stigmatization, and heightened risks for childhood mood variations. Furthermore, many commercial gluten-free alternatives lack routine fortification, potentially compounding celiac-related micronutrient deficiencies. Conclusions: Reactive, individualized accommodations may provide insufficient protection. Improving student safety and well-being supported by this narrative evidence points toward a general framework of structured kitchen guidelines, universal classroom adaptations, and jurisdiction-dependent administrative coordination.
