A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the effectiveness of two different meal management strategies for adolescents with Type 1 Diabetes using Automated Insulin Delivery (AID) systems. Participants will be randomly assigned to either an accurate carb counting group or a simplified qualitative meal-size estimation group, with both groups receiving nutrition guidance from a dietitian. The study will assess glucose control parameters and patient-related outcomes over a 6-month period, with optional follow-up assessments at 12 and 24 months. The goal is to determine which method provides better management of diabetes in this population.

Why it matters

Potential benefit: If successful, this study could improve diabetes management strategies for adolescents, leading to better glucose control and overall health outcomes.

How similar studies have gone: While there have been studies on carb counting and diabetes management, this specific comparison of qualitative meal-size estimation versus accurate carb counting in adolescents is relatively novel.
