Despite recent medical and technological advances, optimal glycemic control (time in range; TIR) and prevention of hypoglycemia remain significant challenges for people living with type 1 diabetes (T1DM). Automated insulin delivery systems (AIDs) combine an insulin pump coupled via an algorithm with a continuous glucose monitor (CGM), allowing constant adjustment of insulin doses according to blood glucose levels. Despite the significant improvement in blood glucose parameters and quality of life with these systems, they are not available to everyone and more and more people with diabetes are resorting to home-made or do-it-yourself (DIY) systems to access this technology. DIY systems are not approved or regulated by Health Canada, despite the growing interest. There have been no studies looking at this type of system in active people living with DbT1, including the risk of exercise-induced hypoglycemia. The primary objective of this study is to evaluate the safety and efficacy of IDA systems in physically active individuals living with type 1 diabetes.This is a real-life observational study in people with commercial IDA (control group) and IDA-DIY. This study includes only one inclusion visit (which may be virtual) and the observation period is 6 weeks. Participants will be required to wear their own artificial pancreas system and give us access to blood glucose and insulin data at the end of the study. They will be required to wear a watch to record physical activity (FitBit). We will ask them to complete information about their diet at least twice a week for a whole day (Keenoa application). Finally, participants will be asked to complete a physical activity diary to complete data (carbohydrates in prevention of activity, insulin suspension, hypoglycemia during or after exercise, etc.).
