  Abstract: Objective To analyze the epidemiological characteristics and developing trends of hospitalized children with diabetes in a children’s hospital in Tianjin from 2014 to 2024, so as to provide evidence for the prevention and treatment of childhood diabetes.Methods The initial diagnosis data of all hospitalized children with diabetes admitted to the hospital from January 1, 2014 to December 31, 2024 were collected. Descriptive epidemiological methods were adopted to analyze the onset time, diabetes classification, age groups, gender and regional distribution of sick children. With year as the independent variable and the number of diabetic cases as the dependent variable, Joinpoint regression analysis was applied to explore the epidemiological trends of childhood diabetes among different populations.Results A total of 885 hospitalized children with diabetes from Tianjin were enrolled in this hospital during 2014-2024. The overall number of cases showed an upward trend with an annual percentage change (APC) of 7.83*. There were 391 cases of type 1 diabetes and 235 cases of type 2 diabetes, and the number of children with type 2 diabetes increased obviously with APC of 27.36*. Among all subjects, 451 were boys and 434 were girls, both presenting rising trends with APC of 10.12* and 5.56* respectively. School-age children accounted for the largest proportion with 473 cases. The case numbers of school-age and adolescent children both showed increasing trends, with APC of 7.95* and 8.95*. In terms of regional distribution, Binhai New Area had the largest number of diabetic children.Conclusion The overall number of hospitalized children with diabetes in this hospital increased steadily from 2014 to 2024. The incidence trend of type 1 diabetes during 2014-2017 and type 2 diabetes within the ten years were basically consistent with the overall trend. Diabetic trends of different genders, school-age and adolescent groups were in line with the general tendency. The Joinpoint regression model can clarify the epidemiological characteristics of childhood diabetes among diverse populations, and offer scientific reference for improving the prevention, control and clinical management of childhood diabetes.
