A longitudinal cohort study describing childhood type 1 diabetes incidence and prevalence rates in British Columbia, Canada over 27 years (1997-2023).

ABSTRACT:

Aims

Our study described incidence and prevalence trends of type 1 diabetes in children and youth under 20 years of age from 1997 to 2023 in the Canadian province of British Columbia (BC) and assessed for a 4-, 5-, or 6-year cyclicity or increase in incidence during the COVID-19 pandemic.

Methods

Using linked population-level databases and a validated case-finding and diabetes differentiating algorithm, we identified children with type 1 diabetes diagnosed between 1997 and 2023. Data sources included hospital admissions, outpatient physician visits, and dispensed prescriptions. Population denominators were based on annual age- and sex-stratified population estimates. We calculated incidence per 100,000 and prevalence per 100 cases, using JoinPoint regression to identify tren
