Background: Physical activity benefits people with type 1 diabetes (PwT1D); however, PwT1D appear less active than their nondiabetic peers. This study seeks to investigate the potential of diabetes technologies in mitigating perceived barriers to physical activity in type 1 diabetes (T1D). Methods: A cross-sectional study with participants from the BETTER registry (age> 14 years) who completed BAPAD-1 (Barriers to Physical Activity in T1D) questionnaire. A significant barrier is defined by score > 5 to BAPAD-1 items. Four groups were defined according to the participants' treatment and blood glucose monitoring mode: Multiple daily injections (MDI) without continuous glucose monitoring (CGM), MDI with CGM, pump with CGM, and those using an automated insulin delivery system (AID). Results: Among 1019 eligible participants, the main perceived barrier is the fear of hypoglycemia. The mean BAPAD-1 score is similar for all groups. A higher proportion of individuals using AID systems reported significant barriers for items fear of hypoglycemia and loss of control over their diabetes compared to the No-CGM-MDI (+20% both), CGM-MDI (+7% and +10%), and CGM+Pump (+9% and +7%). Conclusion: Barriers to physical activity for PwT1D are not reduced by diabetes technologies. Some barriers are even perceived as more important for people using CGM, pump, and AID systems.
