Improvement in Mean CGM Glucose in Young People with Type 1 Diabetes During 1 Year of the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic likely affected youth with type 1 diabetes (T1D). We used electronic health record-extracted data to compare continuous glucose monitoring (CGM) metrics during 1 year of the pandemic with those of the previous year. The sample comprised CGM users, aged 1 to <18 years, with T1D duration ≥6 months (age <6 years) or ≥1 year (age ≥6 years). The prepandemic sample comprised 641 youth (52% female, aged 12.3 ± 3.5, T1D duration 6.0 ± 3.5 years). The pandemic sample comprised 648 youth (52% female, age 13.3 ± 3.5, duration 6.7 ± 3.8 years), with care delivered primarily through telemedicine. Mean CGM glucose was 6.3 mg/dL lower during the pandemic (187.3 ± 35.6) versus prepandemic (193.6 ± 33.0) (P < 0.001). A higher percentage of youth achieved glucose management indicator <7% during the pandemic than the prior year (P < 0.001). Lower CGM glucose values were observed during the COVID-19 pandemic. Future studies are needed to assess how changes in health care delivery, including telemedicine, and lifestyle during this time may have supported this improvement.
