  2. DiabetesPrimary Goal for 2010 Reference: U.S. Department of Health and Human Services. Healthy People 2010: Understanding and Improving Health. 2nd ed. Washington, DC: U.S. Government Printing Office, November 2000. Through prevention programs, reduce the disease incidence, its complications and its economic impact, in addition, to improve quality of life for all those persons that had diabetes or that are at risk to develop the disease.

  3. Epidemiology The worldwide prevalence of DM has risen dramatically over the past two decades, from an estimated 30 million cases in 1985 to 285 million in 2010. International Diabetes Federation projects that 438 million individuals will have diabetes by the year 2030 . Prevalence of both type 1 and type 2 DM is increasing worldwide, the prevalence of type 2 DM is rising much more rapidly, presumably because of increasing obesity, reduced activity levels as countries become more industrialized, and the aging of the population.

  4. The magnitude of the healthcare problem of type 2 diabetes results not just from the disease itself but also from its association with obesity and cardiovascular risk factors, particularly dyslipidaemia and hypertension.  Type 2 diabetes has now been recognized as one manifestation of the “metabolic syndrome”, a condition characterized by insulin resistance and associated with a range of cardiovascular risk factors.

  5. Various cardiovascular risk factors, including • hypertension and dyslipidaemia become • progressively worse with progression from normal • glucose tolerance to IGT/IFG to diabetes.

  6. While there is good evidence for a strong genetic contribution to both obesity and diabetes, the increase in these conditions in both developed and developing countries appears to be due to a changing balance between energy intake and energy expenditure through physical activity. Physical activity levels have probably diminished by half.

  7. The tendency for the increased prevalence of type 2 diabetes to be concentrated in lower socioeconomic groups in developed countries and higher socioeconomic groups in developing countries probably reflects the adoption of a “healthier” lifestyle by better educated people in developed countries, while it is generally the affluent in developing countries who enjoy a high calorie intake and low level of physical activity.

  8. Approximately 1.6 million individuals (>20 years) were newly diagnosed with diabetes in 2010. DM increases with aging. In 2010, the prevalence of DM in the United Sates was estimated to be 0.2% in individuals aged <20 years and 11.3% in individuals aged >20 years. In individuals aged >65 years, the prevalence of DM was 26.9%. The prevalence is similar in men and women throughout most age ranges (11.8% and 10.8%, respectively, in individuals aged >20 years).

  9. In Asia, the prevalence of diabetes is increasing rapidly and the diabetes phenotype appears to be different from that in the United States and Europe—onset at a lower BMI and younger age, greater visceral adiposity, and reduced insulin secretory capacity.

  10. Diabetes is a major cause of mortality, but several studies indicate that diabetes is likely underreported as a cause of death. In the United States, diabetes was listed as the seventh leading cause of death in 2007; a recent estimate suggested that diabetes was the fifth leading cause of death worldwide and was responsible for almost 4 million deaths in 2010 .

  40. There is considerable geographic variation in the incidence of both type 1 and type 2 DM. Scandinavia has the highest incidence of type 1 DM (Finland, the incidence is 57.4/100,000 per year). Japan and China has a much lower rate of type 1 DM (0.6–2.4/100,000 per year); Northern Europe and the United States have an intermediate rate (8–20/100,000 per year).
