The aim of this study is to measure the incidence and prevalence of type 1 diabetes mellitus in children and adolescents in Khartoum State, Sudan. Records of all patients aged 6 months-19 years, living in Khartoum State and who were known to have or newly diagnosed with type 1 diabetes in all health institutes (both governmental and private) during the period January to December 2015, were reviewed. In addition to the records, interviews with patients and caregivers attending the clinics were conducted. Names were double-checked with the Sudanese Childhood Diabetes Association's central registry. Data were analysed using the Statistical Package for the Social Sciences software (SPSS 20). A total of 2,393 children were identified. Males were 1,117 (46.6%) and females were 1,276 (53.3%) with a ratio of 1:1.4, with no significant difference. The prevalence rate was 0.74/1,000. The overall incidence rate was 10.1/100,000. The peak incidence age was between 11 and 15 years (15.9/100,000). The incidence rates in below 5 years and 16-19 years were 8.4 and 7.7/100,000, respectively. There was no significant difference between males and females. In most of the cases, the onset was in the winter months. The commonest month of birth was June.The incidence of type 1 diabetes in Sudan is still considered among the high rate group in the world and in the region. There was an obvious increase in the incidence among the below-5 years age group (8.4/100,000) compared to a figure of 3.5 which was reported earlier from Sudan. For the first time, we report the incidence among the 16-19 age group (7.7/100,000).
