Some studies indicated an economic standard correlation to the incidence rate of diabetes. The incidence rate in China is 3.21% in 1996 quite higher in developing countries, it significantly increased in the following years. Diabetes study of Singapore is quite revealing. In 1975 the incidence rate of diabetes in Singapore was 1.19%; it gradually increased and reached to 4%, in 1992. In 17 years, the incidence rate of diabetes in Singapore increased to 8 times. The case studies from Singapore and Korea clearly indicate that if the rapid economic and social development of countries is directly related to rate of incidence of diabetes. The more country develops, the higher prevalence of diabetes occurs. In the same way, China is rapidly growing during the past two decades. This rapid growth has resulted in increase in the rate of modernization and urbanization. The incidence of prevalence of diabetes in Chinese adult increased three-fold from approximately 1% in 1980 to 3.2% in 1996. The incidence of diabetes is increasing equally with increase in economic growth of the country.
With increase of prevalence of diabetes in Asian Countries China and India are major contributors because of their large populations and growing economies. China is the second largest prevalence of diabetes in the region as greater urbanization, industrialization, and lifestyle changes, because of economic prosperity and increasing rates of obesity.
Growth in economy has resulted in change in the life style and eating habits of Chinese people. Availability of fast foods and a inactive lifestyle, along with lack of physical activities and play, increase in use of television and computers, and mechanization have rapidly changed the behavior patterns of the urbanized young in many of Asia's large cities. Similar situation is prevalent in China.
The epidemiological transition can be observed in its most complete form in developed countries and at it is at its earliest stages in developing countries.
RESULTS OF VARIOUS SURVEYS/STUDIES
First systematic and organized survey was conducted in the late 1970s in China in Shanghai City. It was recorded that incidence of diabetes is 1.07% in 1979 but it was doubled in 1989. Available data shows that the prevalence of diabetes in Shanghai has reached to 2.123% in 1989 while Chengdu was 1.354% in 1992. But in 1982, Chengdu City demonstrated its prevalence of diabetes as 1.29%, which was the highest rate. Another diabetes survey of 14 major cities was conducted by nationwide cooperative group in 1980, it shows the average of prevalence of diabetes was 0.67%. A study conducted in 1993 shows that, the prevalence of diabetes was 2.5% in China but its mortality has become the third largest disease cause death in China after cancer and cardiovascular disease. In 1997, the 11 cities diabetes survey shows the average of prevalence of diabetes was 3.21% that is 3 times double the rate in 1979. A study was carried out in 1996, under the WHO criteria and epidemiology method, a updated 11 major cities survey shows that the prevalence of diabetes was 3.21% in China, which increased almost 5 times compared to the first survey in 1980. It is estimated that the prevalen
