This study is looking at how well two different ways of managing meals work for adolescents and young adults (ages 14-26) with type 1 diabetes who use a hybrid closed loop (HCL) system. You would either use a "Simplified Meal Bolusing" method, where you pick pre-set numbers for small, medium, or large meals, or "Carbohydrate Counting," where you accurately count carbohydrates for all meals and snacks. The main goal is to see which method helps you stay in your target blood sugar range (Time in Range) for up to 12 weeks. The study is currently recruiting 40 participants.

Study design

This is a randomized crossover study, meaning participants will try both methods for a period of time. It involves 40 participants at a single location.

What's involved

You would use the simple meal bolus plan for 4 weeks and then precise carbohydrate counting for 4 weeks. You would also provide your continuous glucose monitor and pump data, and complete surveys.

Compensation

Not stated in the trial record.

Follow-up

Your Time in Range will be measured during the study period, up to 12 weeks.
