A narrative systematic review of definitions and diagnostic criteria for disordered eating and eating disorders in type 1 diabetes.

This systematic review highlights the lack of a unified, evidence-based definition of T1DE, resulting in inconsistent screening, diagnostic and reporting practices.

Establishing clear, consistent, evidence-based diagnostic criteria and screening questionnaires for T1DE is critical to improving early detection and developing targeted interventions.

These findings provide a foundation for refining T1DE definitions as a stepping stone to an international consensus definition.
