Brief Summary

Background: The management of type 1 diabetes (T1D) relies on exogenous insulin administration to compensate for the lack of endogenous insulin production. Optimal glycemic control, essential for preventing long-term complications, requires precise insulin dose adjustments based on carbohydrate intake. Functional insulin therapy (FIT) allows for flexibility in insulin dosing according to carbohydrate consumption, thereby reducing the dietary constraints previously imposed on patients. However, this approach requires increased attention to dietary intake. Individuals with T1D already have a heightened risk of developing eating disorders (EDs). We hypothesize that the dietary knowledge required for FIT may contribute to rigid eating behaviors, thereby increasing the risk of EDs. Objective: This prospective monocentric study aims to determine whether dietary knowledge related to FIT is associated with an increased risk of EDs in individuals with T1D. Methods: The primary outcome measure is the correlation between the Gluciquizz score (a validated tool assessing FIT knowledge) and the risk of EDs, evaluated using the DEPS-R questionnaire (a validated screening tool for ED risk in T1D patients). In addition to this quantitative analysis, a qualitative study will be conducted through semi-structured interviews to explore in greater depth the patients' experiences, their relationship with food, and their perceptions of FIT-related requirements. Perspectives: This study aims to improve the understanding of the impact of FIT on ED risk in T1D. The findings may help identify at-risk patient profiles and enhance therapeutic education and patient management by integrating ED risk considerations. The qualitative approach will provide further insight into patients' individual experiences, facilitating recommendations tailored to their specific needs.
