Objectives: To determine the incidence and prevalence of type 1 diabetes in children younger than 15 yr in the Autonomous Community of Castilla‐Leon (Spain). Research design and methods: All type 1 diabetic cases with onset at <15 yr of age were recorded during 2003–2004. Identified case subjects were ascertained from several sources and the capture–recapture method was used to estimate the completeness of ascertainment. For prevalence, all patients younger than 15 yr with type 1 diabetes at the beginning and at the end of the study were identified. Results: Over the study period, 130 children aged 0–14 yr were diagnosed with type 1 diabetes. The average observed incidence of type 1 diabetes in this population was 22.22/100 000/yr (95% CI 14.57–29.81). Age‐standardized incidence was 22.01/100 000/yr (95% CI 18.18–25.83). The highest incidence was observed in the 5–9 yr age‐group (32.45/100 000/yr, 95% CI 24.31–40.59). The prevalence at the beginning and at the end of the study was 1.01/1000 and 1.18/1000, respectively. Conclusion: Castilla‐Leon appears to have one of the highest incidences of childhood type 1 diabetes in Spain, with recent incidence approaching those of some northern European countries.
