The overall age-adjusted incidence of type 1 diabetes varied from 0.1/100,000 per year in China and Venezuela to 36.8/100,000 per year in Sardinia and 36.5/100,000 per year in Finland. This represents a 350-fold variation in the incidence among the 100 populations worldwide.
Objective The aim of this study was to determine the incidence of type 1 diabetes among children aged 0–14 years in Qatar.
Research design and methods This was a prospective cohort study of the incidence of childhood type 1 diabetes in children aged 0–14 years who were diagnosed with type 1 diabetes from 2006 to 2011 on Qatar. Identified case subjects during this time period were ascertained from several sources and verified using the capture-recapture technique. Data were obtained from the only pediatric diabetes treatment center, Hamad Medical Center (HMC) for children living in Qatar.
Results Over the study period, 385 children aged 0–14 years in Qatar were diagnosed with type 1 diabetes. The incidence of type 1 diabetes in this population over the period 2006–2011 inclusive was 23.11 with a 95% CI of 31.82–40.03.
Conclusions Qatar has a relatively high incidence of type 1 diabetes compared to incidences reported worldwide. The incidence increased over the 16-year study period.
