Association between COVID-19 and Risk for Diabetes After Infection: Vaccination May Reduce the Risk
An increased risk of diabetes following COVID infection, which was reported early in the pandemic, has persisted into the Omicron period. Data from a recent study in the Journal of the American Medical Association (JAMA) indicates that this risk of developing type 2 diabetes following a COVID infection is lower among vaccinated people compared to unvaccinated people. The article was discussed in Medscape and is available here.
The graph below (from cited article) shows the frequency of newly diagnosed cases of diabetes, hyperlipidemia, and hypertension that occurred 90 days before and 90 days after COVID-19 infection in the total population of 23,709 patients (A), in a subset of 14,856 patients who were unvaccinated prior to infection (B), and in a subset of 8,853 patients who were vaccinated prior to infection (C). The benchmark conditions were urinary tract infection and gastroesophageal reflux; these conditions were used as a marker of, or to control for, the influence of healthcare engagement since they have been found to be unrelated to COVID-19.
When comparing the risk of newly diagnosed diabetes, hyperlipidemia, and hypertension to the risk of the benchmark conditions, only the risk for new-onset diabetes was significant. In addition, the risk for diabetes after COVID-19 infection was higher among those who had not been vaccinated compared with those who had received the vaccine.
