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

The COVID-19 pandemic likely affected youth with type 1 diabetes (T1D). We used EHR-extracted data to compare CGM metrics during one year of the pandemic with the previous year. The sample comprised CGM users, aged 1-18 years, with T1D duration ≥6 months (age <6 years) or ≥1 year (age ≥6 years). The pre-pandemic sample comprised 641 youth (52% female, age 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) vs. pre-pandemic (193.633.0) (p<.001). A higher percentage of youth achieved glucose management indicator (GMI) <7% during the pandemic than the prior year (p<0.001). Lower CGM glucoses were observed during the COVID-19 pandemic. Future studies are needed to assess how changes in healthcare delivery, including telemedicine, and lifestyle during this time may have supported this improvement.
