This systematic review examined definitions and diagnostic criteria for disordered eating in adults with type 1 diabetes (T1DE), analyzing 61 studies with 111,208 participants. The review found 29 distinct methods for defining T1DE, highlighting a lack of standardized criteria, which complicates effective screening and treatment. The findings underscore the need for unified diagnostic criteria.
Key findings
- T1DE affects 8-37.1% of adults with type 1 diabetes, indicating a significant prevalence.
- A total of 29 distinct methods were identified for defining T1DE across the studies.
- Approximately 75% of studies assessed insulin omission behaviors, but definitions varied widely.
Why it matters
The absence of standardized definitions for T1DE complicates diagnosis and treatment, potentially leading to increased morbidity and mortality. Establishing clear criteria is essential for improving patient outcomes and guiding clinical practice.
