To investigate the incidence and secular trend of pediatric type 1 diabetes from 1999 to 2021, including the coronavirus disease 2019 (COVID-19) pandemic years, in Oita Prefecture, Japan.

The type 1 diabetes incidence in children aged < 15 years increased annually by 5.3% among all children, especially in boys aged 10-14 years by 8.1%, over the past 23 years.
