Abstract：Objective To investigate the incidence trend of diabetes among children and adolescents in Ningbo City, Zhejiang Province from 2011 to 2021, so as to provide the basis for the prevention and control of diabetes among children and adolescents. Methods Data on diabetes incidence among children and adolescents aged 0 to 18 years in Ningbo City were collected through the Diabetes Monitoring Platform of the Ningbo Chronic Disease Collaborative Management System from 2011 to 2021. Crude incidence rates were calculated and standardized using data from the Sixth National Population Census in 2010. The trend of incidence rates were analyzed by average annual percent change (AAPC). Results A total of 701 cases of diabetes among children and adolescents were reported in Ningbo City from 2011 to 2021. The crude and standardized incidence rates were 6.86/105 and 7.27/105, respectively, showing upward trends (AAPC=5.886%, 7.147%, both P<0.05). The crude and standardized incidence rates of type 1 diabetes mellitus were 3.36/105 and 3.35/105, respectively, with no significant trend observed (AAPC=1.229%, 1.449%, both P>0.05). The crude incidence rate was higher in children and adolescents aged 10 to <15 years (4.56/105) than in other age groups (all P<0.05). The standardized incidence rate was higher in females than in males (3.49/105 vs. 3.04/105, P<0.05). The standardized incidence rate was higher in urban areas than in rural areas (3.60/105 vs. 3.15/105, P<0.05). The crude and standardized incidence rates of type 2 diabetes mellitus were 3.43/105 and 3.87/105, respectively, showing upward trends (AAPC=4.904%, 7.579%, both P<0.05). The crude incidence rate was higher in children and adolescents aged 15 to 18 years (10.53/105) than in other groups (all P<0.05). The crude incidence rates in children and adolescents who aged 10 to <15 years and 15 to 18 years showed upward trends (AAPC=15.030%, 6.637%, both P<0.05). The standardized incidence rate was higher in males than in females (4.01/105 vs. 3.57/105, P<0.05). The standardized incidence rate was higher in urban areas than in rural areas (4.57/105 vs. 3.34/105, P<0.05). Conclusions From 2011 to 2021, the incidence of type 2 diabetes mellitus showed an upward trend, with cases mainly concentrated in children and adolescents aged 15 to 18 years, males, and those living in urban areas. The incidence of type 1 diabetes mellitus remained stable, with cases mainly concentrated in children and adolescents aged 10 to <15 years, females, and those living in urban areas.
