The prevalence of diabetes around the world has increased from 30 million in 1985 to the current 235 million, and is expected to grow to 300 million in 2030, with more than 75 percent occurring in countries such as India and China. In China, economic prosperity and changes in diet and lifestyles have resulted in steep increase in prevalence of overweight, obesity, and diabetes. According to the latest study, in adults of 20 years of age or older, the incidence of diabetes has reached 9.7% and the prevalence 92.4 million. In a nationwide, cross over cohort study that was recently completed in China, the results showed that the duration of diabetes is positively correlated with the incidence of CAD and all microvascular diabetic complications. Preventing diabetes progression and preventing the onset of cardiovascular diseases early on at the stage of newly diagnosis is thus one of the most important goals in managing type 2 diabetes.
