Impact of covid-19 lockdown on glycemic control in patients with type 1 diabetes.

Abstract Introduction The COVID-19 pandemic has forced governments to take exceptional measures to minimize its spread, imposing lockdown policies. The aim of this study was to evaluate the impact of lockdown on type 1 diabetes (T1D) glycemic control. Material and Methods People with T1D using flash glucose monitoring were included. Data from the 14 days before lockdown were compared with data from the last 14 days after 8 weeks of lockdown. Results A total of 307 patients were included (age 45.8±12.6 years, 50.2% male, diabetes duration 21.1±12.3 years). Only one patient had COVID-19 infection. Mean glucose decreased from 166.89±29.4 mg/dL to 158.0±29.0 and estimated HbA1c declined from 7.4±1.0 to 7.1±1.0% (54±10.9 vs 57±10.9 mmol/mol; p 180 mg/dL and >250 mg/dL decreased from 37.3±1.9% to 32.0±17.1% and from 13.0±11.3 to 10.3±10.6%, respectively; (p Conclusion Despite the limitations of lockdown, glycemic control improved in patients with T1D. These results suggest that having more time for self-management may help improve glycemic control in the short term.
