Obesity and diabetes are correlated, with WHO estimating that there are currently about 170 million diabetics worldwide, and that this will increase to 300 million by 2025. Obesity is a major risk factor for diabetes and an independent disease. For every 1 kg increase in body weight, the risk of developing the disease increases by at least 5%. The risk of developing type II diabetes is three times higher in obese people than in normal people, and about 50% of obese people will develop diabetes in the future. 80% of people with type II diabetes are overweight at the time of diagnosis. Obesity can shorten the life expectancy of people with type II diabetes by as much as eight years. At the same time, the obesity epidemic has reached alarming proportions in both developed and developing countries. More than 1 billion adults worldwide are already overweight, and at least 300 million are overweight. The latest published information shows that China is estimated to have 200 million overweight people and more than 60 million obese people. Among them, the overweight rate and obesity rate of adults in large cities are as high as 30.0% and 12.3% respectively, and the obesity rate of children has reached 8.1%. Juvenile diabetes in China has accounted for 5% of all diabetics, and the annual rate of 10% rise. Let’s first look at the situation in Shanghai, the Liberation Daily said, at present, Shanghai has about 1.2 million people with diabetes, more than 80% of obese patients. Experts pointed out that diabetes has become the third leading cause of death in China’s population, and health education must be increased so that more people in general can prevent diabetes before it happens. The report said that 30 percent of adults in Shanghai are overweight or obese. Obesity is an important cause of diabetes, the national incidence of adult diabetes from the 1980s 1% to 6% this year, Shanghai has reached 10%.
