Effects of a moderate carbohydrate diet on children with type 1 diabetes using hybrid closed-loop therapy

The Impact of Carbohydrate Restriction on Glycemic Control in Children and Adolescents With Type 1 Diabetes Using a Hybrid Closed-loop Insulin Delivery System: a Randomized Cross-over Study

Not applicable Interventional Universitaire Ziekenhuizen KU Leuven · NCT06567158

This study tests if a moderate carbohydrate diet can help children with type 1 diabetes using insulin pumps manage their blood sugar better and improve their quality of life.

What this trial studies

This study investigates the effects of a moderate carbohydrate diet compared to a traditional diet on glycemic control and quality of life in children aged 7 to 17 years with type 1 diabetes who are using hybrid closed-loop insulin delivery systems. In a randomized, crossover design, 28 participants will follow each diet for four weeks, with a two-week run-in period. The goal is to clarify the impact of carbohydrate restriction in this population, which has been under-researched. The findings could provide insights into dietary management alongside insulin therapy.

Who should consider this trial

Good fit: Ideal candidates are children aged 7 to 17 years with at least six months of type 1 diabetes diagnosis and three months of experience using a hybrid closed-loop insulin delivery system.

Not a fit: Patients who are not using a hybrid closed-loop insulin delivery system or are outside the age range of 7 to 17 years may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve glycemic control and quality of life for children with type 1 diabetes.

How similar studies have performed: While there is limited research on carbohydrate restriction in children with type 1 diabetes, previous studies have shown potential benefits in adults, making this approach both novel and promising.
