Background: Data on the epidemiology of type 1 diabetes among children in Turkey are limited.
Objective and hypotheses: The aim of this study was to report, for the first time, the incidence and prevalence of childhood type 1 diabetes in Turkey using a nationwide registry.
Method: Information on birth date, city of birth, diagnosis date and gender of all type 1 diabetes patients aged less than 18 years were obtained from the Turkish Social Security Institute from January 2011 through December 2013.
Results: There were 17 175 prevalent cases of type 1 diabetes over the 3-year period. The prevalence of type 1 diabetes was 0.75/1000. There were 2465 incident cases in 2013. The female to male cases ratio was 1.02. The incidence was 10.4/100 000 for males and 11.3/100 000 for females. The age standardised incidence rate was (10.8/100 000) according to the World Health Organization standard population estimated using the direct method. The highest proportion of cases was diagnosed between the ages of 10 and 14.
Conclusions: This is the first study to report the incidence and prevalence of type 1 diabetes in children in Turkey. The location of Turkey, as a bridge between Asia and Europe, is reflected in its incidence, which is higher than Asia but lower than Europe.
