• Habeb AM, Al-Magamsi MSF, Halabi S, Eid IM, Shalaby S, Bakoush O. High incidence of childhood type 1 diabetes in Al-Madinah, North West Saudi Arabia (2004-2009). Background: There is a geographical variation in the incidence of childhood type 1 diabetes mellitus (T1DM) with a steady increase reported from some countries. However, data on the incidence of childhood T1DM in Kingdom of Saudi Arabia are limited. Objective: To identify the incidence rate (IR) and epidemiological trends of childhood T1DM in the largest city of northwest Saudi Arabia. Methods: All patients with newly diagnosed T1DM aged 0-12 yr living in the city between 2004 and 2009 were identified from different sources. The data were analyzed according to age, sex, and month of presentation. Results: In total, 419 patients (249 girls) were diagnosed between 2004 and 2009 inclusive. The mean age at diagnosis was 6.9 ± 3.5 yr. The mean annual age-standardized IR was 29.0 (95% confidence interval 26.0-32.0). The incidence was significantly higher in the 10-12-yr age group than in younger children (p < 0.001) and higher in girls than in boys (33.0 vs. 22.2 per 100 000; p < 0.001). There was no significant increase in the annual incidence during the 6-yr period (p = 0.68) and more cases were diagnosed during autumn and winter months (p = 0.002). Conclusions: Al-Madinah city has the highest reported incidence of childhood T1DM in the Middle East and North Africa region. Further studies to identify the reasons for this high incidence are needed.
