Developing countries are growing faster than developed countries. (200% vs. 45%), and in the 21st century DM will be prevalent in developing countries such as China and India. In the past 20 years, China’s national economy has developed rapidly, people’s living standards have improved rapidly, the disease spectrum in China has undergone significant changes, chronic non-communicable diseases, including diabetes, have gradually become an important social health problem. According to the information in 1996, diabetes mellitus and impaired glucose tolerance in China accounted for 3.2% and 4.8% of the total population over 20 years old respectively, i.e., the population with abnormal blood glucose was close to 100 million. The prevalence of type 2 diabetes in children has increased rapidly in recent years and is a cause for concern.
