Through the present work, the authors aimed to investigate the impact of coronavirus disease 2019 lockdown on glycemic control and factors associated with people living with type 1 diabetes. An observational evaluation study was conducted using a self-reported questionnaire on behavioral changes and glycemic information from flash glucose monitoring during the lockdown in 1,378 individuals living with type 1 diabetes who used a French dedicated nationwide web application (CoviDIAB).
The main outcome was the change of the mean glucose level 2 months before and 1 month after the lockdown. Results showed and improvement in glucose control. Factors associated with better glycemic control were a decrease of alcohol consumption, an increase in the frequency of flash glucose monitoring scans and in the number of hypoglycemia events, and an easier diabetes control perception. Thus, lockdown had a positive impact on glycemic control in people with type 1 diabetes.
