Increase in Incidence of type 1 diabetes in children during the Covid-19 pandemic
During the COVID-19 pandemic, more children and adolescents newly developed type 1 diabetes than in previous years. This is shown by a recent study of the DZD, the University of Giessen and the University of Ulm with co-authors from other centers in Germany, based on the data of the multicenter German Diabetes Prospective Follow-up Registry (DPV*).
The aim of this study was to investigate the incidence of type 1 diabetes in children and adolescents during the COVID-19 pandemic in Germany in comparison to previous years. For this purpose, the researchers recorded the children and adolescents aged between six months and under 18 years newly diagnosed in Germany for the period from January 1, 2020 to June 30, 2021. During this period, 5,162 children and adolescents with new-onset T1D were registered in the DPV. This corresponds to an incidence of 24.4 per 100,000 patient-years. Using Poisson regression models, the researchers determined the expected incidence for 2020/21 from data from 2011 to 2019 to be only 21.2, meaning that the observed incidence during the Corona pandemic was significantly higher than the expected incidence (24.4 [95% CI 23.6-25.2] vs. 21.2 [20.5-21.9]; incidence rate ratios (IRR) 1.15 [1.10-1.20]; P < 0.001).
