Increased Incidence of Type 1 Diabetes in Children and Adolescents During the COVID-19 Pandemic

A recent meta-analysis analyzed 42 studies and over 100,000 youths found that the incidence of type 1 diabetes in children and adolescents was higher during the COVID-19 pandemic compared to before. The study also reported an increase in diabetic ketoacidosis (DKA) during this period.

Despite no clear mechanism explaining the association between SARS-CoV-2 infection and subsequent increased risk of diabetes, population-based studies suggested that the increase in incidence may be due to an immune-mediated mechanism. However, the underlying mechanisms and long-term implications require further investigation. Future studies are needed to assess whether this trend persists and to elucidate possible mechanisms to explain these temporal changes.
