OBJECTIVE To investigate the impact of coronavirus disease 2019 lockdown on glycemic control and factors associated with people living with type 1 diabetes. RESEARCH DESIGN AND METHODS An observational evaluation from a self-reported questionnaire on behavioral changes and glycemic information from flash glucose monitoring (FGM) during the lockdown in 1,378 individuals living with type 1 diabetes who used a French dedicated nationwide web application (CoviDIAB). RESULTS The main outcome was the change of the mean glucose level 2 months before and 1 month after the lockdown. We found that mean glucose improved from 9.1 ± 1.7 mmol/L to 8.7 ± 1.7 mmol/L (P CONCLUSIONS Our findings suggest that lockdown has a positive impact on glycemic control in people with type 1 diabetes.
