IDF Diabetes Atlas
- This paper describes the methodology, results and limitations of the 2013 International Diabetes Federation (IDF) Atlas (6th edition) estimates of the worldwide numbers of prevalent cases of type 1 diabetes in children (<15 years). The majority of relevant information in the published literature is in the form of incidence rates derived from registers of newly diagnosed cases. Studies were graded on quality criteria and, if no information was available in the published literature, extrapolation was used to assign a country the rate from an adjacent country with similar characteristics.
- The Africa Region (AFR), where diabetes was once rare, has witnessed a surge in the condition. Estimates for type 1 diabetes suggest that about 39,000 people suffer from the disease in 2013 with 6.4 new cases occurring per year per 100,000 people in children <14 years old. Type 2 diabetes prevalence among 20–79-year-olds is 4.9% with the majority of people with diabetes <60 years old; the highest proportion (43.2%) is in those aged 40–59 years. Figures are projected to increase with the numbers rising from 19.8 million in 2013 to 41.5 million in 2035, representing a 110% absolute increase.
