Global burden of type 2 diabetes attributable to SARS-CoV-2 infection.

What was studied

This was a review of cohort studies on COVID-19 and later diabetes. It asked if infection with SARS-CoV-2 is linked to new type 2 diabetes. It also estimated how many new cases worldwide might be linked to infection. The estimate used pooled risk and global burden data for 2023.

What they found

SARS-CoV-2 infection was linked to a higher risk of new type 2 diabetes. The risk ratio was 1.25. Results differed a lot between studies. The link was seen in mixed-variant studies but not in studies of a single variant. The link with type 1 diabetes was not significant. The authors estimated 274,889 new type 2 cases were linked to infection in 2023.

What it means for patients

The authors said infection was linked to a modest rise in type 2 diabetes risk. They said ongoing metabolic monitoring after infection is needed.

Why it is not certain yet

The range of likely values included no effect. Results differed a lot between studies. The case estimate was built from modelling, not counted directly. A link seen in cohort studies does not prove cause.
