Lockdown resulting from the COVID-19 pandemic was an unpreceded model of the impact of lifestyle on chronic diseases, especially for adolescents and young adults with type 1 diabetes (T1D) whose lifestyle is known to strongly impact disease management. The investigators aimed to assess changes in self-monitoring and glycemic control in this population before, during, and after the two-month French lockdown. Te investigators hypothesized an improvement in glucose control and glucose sensor usage. The protocol will include all patients with T1D from 13 to 25 years old using a flash glucose monitoring related to the LibreView cloud platform. The primary outcome, evolution of percentage of glucose time in range 70-180 mg/dL (TIR), and secondary outcomes (glucose management indicator GMI, time spent below range TBR, and sensor usage) will be analyzed with a linear mixed-effects regression model.
