Introduction: Type 1 diabetes (T1D) is a chronic disease characterized by insufficient insulin production by the pancreas, leading to high blood glucose levels. Some countries have reported an increase in the incidence of T1D during the COVID-19 pandemic. Objective: To examine whether the incidence of T1D has increased during the COVID-19 pandemic in Catalonia. Methods: We estimated the expected incidence of T1D for 2020-2021 using a Poisson regression model based on historical data from 2010 to 2019. We compared the expected incidence with the observed incidence obtained from the population-based T1D registry of the PADRIS data analysis program of AQuAS. Results: In 2020, there was no significant increase in incidence compared to 2019, but in 2021 there was a significant increase of 28%. The largest increases occurred among people under 18 years old and women. Conclusions and discussion: There was a notable and statistically significant increase in T1D cases in Catalonia during the COVID-19 pandemic, although a causal relationship between the pandemic and diabetes cannot be established. Further studies are needed to explore the possible biological or social mechanisms that could explain this phenomenon and its clinical and health implications.
