Comparison of the association between COVID-19 and new onset diabetes in a regional and national dataset
Authors' conclusion
Persons infected with COVID-19 during the initial 18 months of the pandemic demonstrated a higher incidence of new onset diabetes, which was evident in all populations. Diabetes incidence was especially high in an academic center population with higher health disparities, and in patients with a more severe infection with the virus.
Study context
- Population
- Patients in a large academic medical center (UKHC), privately insured patients in MarketScan (MarketScan) claims, and a MarketScan subset with lab tests
- Exposure
- COVID-19 infection vs no COVID infection and prepandemic controls
- Outcome
- New onset (incident) diabetes following COVID-19 infection
Methodological detailsthree databases
- Three databases

Observational data: associations, not effects.
Further findings
Incident diabetes by care setting
- Incident diabetes elevated even in patients treated in the outpatient setting and much higher in those treated in the inpatient setting, especially those who required inpatient interventions
