Objective To assess the trends in the incidence of type 1 diabetes between 1997 and 2010 among 0–17‐yr‐old Israeli Jews and Arabs compared with global trends. Methods Data on children with newly diagnosed type 1 diabetes reported by pediatric endocrinologists from 19 medical centers to the Israel Center for Disease Control, as part of the National Diabetes Register. Results During 1997–2010, 2857 Jews and 757 Arabs were diagnosed with type 1 diabetes. The average age‐adjusted incidence among Jews was higher than Arabs [12.2 per 100 000, 95% confidence interval ( CI ) 10.5–14.2 and 8.9 per 100 000, 95% CI 7.5–10.7, p = 0.0001, respectively], however, the annual percent change was higher for Arabs compared with Jews (4.0 vs. 3.6%, p = 0.005, respectively). The mean age at diagnosis was similar for Jews and Arabs (9.6 ± 4.4 vs. 9.9 ± 4.4 yr, p = 0.08), and it remained stable during 1997–2010 in both ethnic groups (p = 0.6). In both Jews and Arabs the highest annual percent change was observed in younger children. It was 4.9% for children aged 5–9 yr and 10.7% for children aged 0–4 yr, respectively. There were no differences in the frequency of diabetic ketoacidosis ( DKA ) between Jews (39.9%) and Arabs (41.3%), (p = 0.5). Conclusion Type 1 diabetes incidence of Jews and Arabs in Israel is increasing. The incidence is higher in Jews than in Arabs; however, the annual percent change is higher in Arabs than in Jews. In both Ethnic groups the incidence of type 1 diabetes is increasing especially among young children.
