Is this trial a fit for you?

Likely a good fit

Adults (18+) with a confirmed diagnosis of type 1 diabetes for at least three months who can use a computer or smartphone and participate in videoconference visits are ideal candidates.

Probably not a fit

People who cannot complete online questionnaires or videoconference interviews, are pregnant or breastfeeding, or are under legal guardianship are unlikely to benefit from participation.

What this trial studies

This is a prospective, monocentric observational study run from Grenoble with national recruitment that collects data remotely to limit participant burden. Participants complete an online questionnaire, a videoconference session to measure FIT-related dietary knowledge and screen for eating disorder risk, then a self-administered follow-up questionnaire and a final videoconference interview. Adults with confirmed type 1 diabetes diagnosed at least three months prior who can use a smartphone or computer are eligible, while those unable to complete online visits, pregnant or under legal guardianship are excluded. The primary aim is to determine whether higher levels of FIT dietary knowledge are associated with an increased risk of disordered eating behaviors.

Why it matters

Potential benefit: If successful, the findings could help identify patients at higher risk of eating disorders and inform safer education and support strategies around insulin dosing and diet.

How similar studies have gone: Previous research has documented a higher prevalence of eating disorders in people with type 1 diabetes, but the specific link between FIT-related dietary knowledge and eating disorder risk is largely untested.
