IDF Diabetes Atlas
- Diabetes mellitus describes a group of metabolic disorders characterised by increased blood glucose concentration. People living with diabetes have a higher risk of morbidity and mortality than the general population. The global prevalence of diabetes in adults has been increasing over recent decades. In 1964, it was estimated that 30 million people had diabetes . Less than 40 years later, the WHO estimated that there were 171 million people living with diabetes . The International Diabetes Federation (IDF) estimated the global prevalence to be 151 million in 2000 , 194 million in 2003 , 246 million in 2006 , 285 million in 2009 , 366 million in 2011 , and 382 million in 2013 .
- In the 2013 issue of the International Diabetes Federation (IDF) Diabetes Atlas, the prevalence of diabetes in the Western Pacific (WP) Region was reported to be 8.6% in 2013, or 138 million adults, and estimated to rise to 11.1%, or 201 million adults, in 2035. The prevalence estimates of impaired glucose tolerance in 2013 and 2035 were 6.8% and 9.0%, respectively. Over 50% of people with diabetes were undiagnosed. In 2013, 187 million deaths were attributable to diabetes, 44% of which occurred in the under the age of 60.
- The North America and Caribbean (NAC) Region faces a high burden of diabetes. In 2013, the number of children (aged 0–14 years) with type 1 diabetes was 108,600, with 16.7 new cases diagnosed per 100,000 children. Furthermore, there were 36,755,500 individuals with diabetes (mostly type 2 diabetes) in adults (20–79 years), and an additional 44,277,700 individuals had impaired glucose tolerance. The age-adjusted prevalence of diabetes in adults was 9.6%; the second highest among the seven Regions of the International Diabetes Federation.
- The prevalence of diabetes is rapidly increasing worldwide. Type 2 diabetes may remain undetected for many years, leading to severe complications and healthcare costs. This paper provides estimates of the prevalence of undiagnosed diabetes mellitus (UDM), using available data from high quality representative population-based sources.
