Prevalence and incidence of type 1 diabetes in children aged 0–14years old in New Zealand in 2021

AimNational prevalence and incidence data are important for understanding population trends and allocating health‐care resources. We aimed to provide a current national snapshot of prevalence and annual incidence rates for children aged 0–14 with type 1 diabetes (T1D) in Aotearoa New Zealand and to identify differences associated with demographic variables.MethodsPaediatric diabetes centres across Aotearoa were invited to record anonymised demographic and diabetes data on children under their services between 1 October 2020 and 30 September 2021. National prevalence and incidence were calculated using usually resident population counts from the 2018 census. The effect of ethnicity on prevalence and incidence was assessed using Poisson regression.ResultsThere were 1209 children aged 0–14 with T1D in October 2021. The national prevalence was 131/100 000 (95% confidence interval (CI) 124–139). European children had twice the prevalence as those of Māori or Pacific ethnicity (P
