Insulin delivery technology and eating behaviours in people with type 1 diabetes

The diabEAT Study: Insulin dElivery Technologies And eaTing Behaviours in People With Type 1 Diabetes

McGill University · NCT07348432

This project will test whether automated insulin delivery systems change eating behaviours and make carbohydrate counting easier for people aged 12 and older who have type 1 diabetes in Canada.

What this trial studies

This is a cross-sectional observational study comparing people with type 1 diabetes who use automated insulin delivery (AID) systems to those using non-automated delivery. The study measures disordered eating behaviours, carbohydrate counting accuracy, and glycemic stability, and looks for differences by gender and by age group including youth (12–17 years). Participants provide data via smartphone apps and existing glucose/insulin device records, and carbohydrate-counting inaccuracy thresholds for maintaining glucose control will be estimated for each delivery type. The goal is to understand whether AID use is linked to lower food-management burden or different patterns of disordered eating.

Who should consider this trial

Good fit: Ideal candidates are people aged 12 or older living in Canada with type 1 diabetes for more than one year who use at least two daily insulin injections or an insulin pump and have used their current insulin delivery system for three months or more.

Not a fit: People who are pregnant or breastfeeding, do not speak English or French, lack a smartphone, or live outside Canada are not eligible and therefore will not benefit from participation in this study.

Why it matters

Potential benefit: If successful, the findings could help tailor diabetes technology choices and education to reduce eating-related burden and lower risk of disordered eating while maintaining glucose control.

How similar studies have performed: Previous studies show AID systems improve glycemic control and quality of life, but their specific effects on eating behaviours and disordered eating are largely untested.
