Risks amplified Al-Aly and Yan Xie, an epidemiologist also at the VA St Louis Healthcare System, looked at the medical records of more than 180,000 people who had survived for longer than a month after catching COVID-19. They compared these with records from two groups, each of which comprised around four million people without SARS-CoV-2 infection who had used the VA health-care system, either before or during the pandemic. The pair previously used a similar method to show that COVID-19 increases the risk of kidney disease3, heart failure and stroke. The latest analysis found that people who had had COVID-19 were about 40% more likely to develop diabetes up to a year later than were veterans in the control groups. That meant that for every 1,000 people studied in each group, roughly 13 more individuals in the COVID-19 group were diagnosed with diabetes. Almost all cases detected were type 2 diabetes, in which the body becomes resistant to or doesn’t produce enough insulin. The chance of developing diabetes rose with increasing severity of COVID-19. People who were hospitalized or admitted to intensive care had roughly triple the risk compared with control individuals who did not have COVID-19. Even people who had mild infections and no previous risk factors for diabetes had increased odds of developing the chronic condition, says Al-Aly. Of the people with COVID-19 who avoided hospitalization, an extra 8 people out of every 1,000 studied had developed diabetes a year later compared with people who were not infected. People with a high body-mass index, a measure of obesity — and a considerable risk factor for type 2 diabetes — had more than double the risk of developing diabetes after a SARS-CoV-2 infection.
