Satisfaction of Specific Modes Related to Physical Activity in People Living With Type 1 Diabetes and Using an Hybrid Closed-loop System

Source: ClinicalTrials.gov · Last updated 5 May 2026

Brief summary (registry, in English)

The BF-ACT study is a single-center, non-interventional (RIPH3) descriptive study conducted at CHU Grenoble Alpes. It aims to evaluate the satisfaction of adults with type 1 diabetes using closed-loop insulin delivery systems, specifically regarding the "physical activity mode" designed to adapt insulin delivery during exercise. Although physical activity is essential for managing type 1 diabetes, it remains challenging due to the risk of hypoglycemia. Closed-loop systems have improved glucose control, but their effectiveness during exercise depends on multiple factors, and their real-life use can be complex. Currently, little is known about patient satisfaction and experience with these specific modes. The study will collect data through a self-administered questionnaire, distributed to eligible patients (≥18 years old, with type 1 diabetes, using a closed-loop system for at least 4 months). The primary outcome is the satisfaction score based on the questionnaire. Secondary objectives include describing physical activity perception, usage of the activity mode, and comparing users versus non-users. Approximately up to 900 patients may be included over a 4-month recruitment period. Clinical and glucose monitoring data will also be collected from medical records. The results are expected to improve patient education, device usability, and support for physical activity in people living with type 1 diabetes.
