The World Health Organization recently announced that 1 in 10 people in China are diabetic. At a recent seminar on China’s cardiovascular disease prevention and control action plan in Beijing, experts also pointed out that four chronic diseases – cardiovascular disease, tumor, diabetes, and respiratory disease – cause 86.6% of all deaths in China, and the situation of chronic disease prevention and control is very serious. How to prevent and control chronic diseases such as diabetes? China is the first country with diabetes in name only. The awareness rate, treatment rate and control rate of diabetic patients are still very low, 30.1%, 25.8% and 39.7% respectively, reflecting the current situation of high prevalence and low level of control of diabetes in China. In fact, not only diabetes, the incidence of chronic diseases in China has been on a rapid rise in recent years. The disease burden caused by chronic diseases such as cardiovascular diseases and malignant tumors accounts for nearly 70% of the total disease burden, and the prevention and treatment of chronic diseases cannot be delayed. Chronic diseases tend to cause disability, affecting the ability to work and quality of life Experts, chronic diseases are divided into four main types: cardiovascular diseases (such as heart attacks and strokes), tumors, chronic respiratory diseases (such as chronic obstructive pulmonary disease and asthma) and diabetes. The hazards of chronic diseases mainly cause damage to important organs such as brain, heart and kidney, easily cause disability, affect work capacity and quality of life, and are extremely expensive to treat. The Report on Nutrition and Chronic Diseases in China (2015) was released recently, which shows that the prevalence of hypertension among adults aged 18 and above was 25.2% and the prevalence of diabetes was 9.7% in 2012, with an increasing trend compared to 2002. According to the analysis of national tumor registry results in 2013, the incidence rate of cancer in China is 235/100,000, with lung cancer and breast cancer ranking first among men and women respectively, and the incidence rate of cancer in China has been on the rise in the past 10 years. Cardiovascular diseases, cancer and chronic respiratory diseases are the main causes of death, accounting for 79.4% of the total deaths, of which the mortality rate of cardiovascular diseases is 271.8/100,000, the mortality rate of cancer is 144.3/100,000 (the top five are lung cancer, liver cancer, stomach cancer, esophageal cancer and colorectal cancer), and the mortality rate of chronic respiratory diseases is 68/100,000. According to statistics, there are nearly 300 million people with diagnosed chronic diseases in China, of which half of the burden of chronic diseases occurs in people under the age of 65. Four major factors, including tobacco and alcohol, predispose to chronic diseases Chronic diseases have become the main cause of death in China’s urban and rural areas, according to statistics, the proportion of deaths due to chronic diseases in China’s urban and rural areas is as high as 85.3% and 79.5% of the total number of deaths, respectively. Even in poor areas, deaths caused by chronic diseases can not be ignored, and many poor counties have reached 60% of this proportion. The World Health Organization survey shows that 60% of the causes of chronic diseases depend on the individual’s lifestyle and are also related to factors such as genetics, medical conditions, social conditions and climate. Among the lifestyle factors, unreasonable diet, insufficient physical activity, tobacco use and harmful use of alcohol are the four major risk factors for chronic diseases. In recent years, the rapid economic development in rural areas of China has gradually solved the problem of food and clothing, but rural health resources and residents’ knowledge level are relatively low, so “rich diseases” have the opportunity to take advantage of. The prevalence of diabetes in rural areas is increasing rapidly and has become a high prevalence of the disease; the prevalence of diabetes among adults in rural China rose from 1.8% in 2002 to 8.4% in 2010, faster than in urban areas. Improved living standards and mechanization of farming methods in rural areas have made people far less physically active, and unreasonable diets and poor lifestyles have led to an increase in risk factors such as obesity and dyslipidemia, coupled with relatively low health resources and knowledge of rural residents, making chronic diseases such as diabetes prone to high incidence. The prevalence of hypertension among adults in China rose from 18.6 percent in 2002 to 21.2 percent in 2012, with nearly 300 million people suffering from hypertension. “The awareness rate, treatment rate and control rate are all very low. Many people in rural areas, especially in remote and remote areas, have not had their blood pressure measured and are unaware that they have hypertension. If hypertension is not effectively controlled, then stroke will continue to rise.” A proper diet is based on the “10 tennis balls” principle. Low physical exertion, including low physical activity and reduced daily activities, is the primary factor in the development of chronic diseases. He recommends exercising at least three times a week for an average of half an hour or more per day. The best time to exercise is around 4-5 p.m., followed by 2-3 hours in the evening after meals. The exercise is mainly aerobic, including endurance-type exercises such as brisk walking, jogging, swimming and strength-type exercises such as equipment, dumbbells and pullers. Endurance and strength exercises should be combined, and even older people over 65 years old should do 2-3 times a week, 8-10 kinds of strength exercises. A reasonable diet can be based on the principle of “ten tennis balls”: daily consumption of meat should not exceed the size of one tennis ball, staple foods should be equivalent to the size of two tennis balls, fruits should be the size of three tennis balls, and vegetables should be the size of no less than four tennis balls. In addition, we should also add “four ones” every day, namely 1 egg, 1 pound of milk, 1 small handful of nuts and 1 poker-sized piece of tofu. China’s fat intake is excessive, with an average dietary fat supply ratio of 32.9%, and the intake of pork with high fat content has increased significantly, exceeding the upper limit of a reasonable diet of 25%-30% recommended by the Dietary Guidelines for Chinese Residents. To solve the problem of unreasonable dietary structure, we should take the Dietary Guidelines for Chinese Residents as a guide, vigorously advocate balanced diets, adhere to the Chinese dietary pattern of plant-based foods, moderate intake of animal-based foods, and increase the intake of fruits and vegetables, soybeans and dairy products. In the case of diabetes, for example, patients can significantly reduce the risk of complications by taking measures to lower sugar, lower blood pressure, adjust blood lipids and control body weight, and correct poor lifestyle habits such as quitting smoking, limiting alcohol, controlling oil, reducing salt and increasing physical activity. Smoothly controlling the disease and delaying complications, patients can enjoy life as normal people. The cause of chronic disease prevention and control can be closely integrated with the Internet. Wearable devices are increasingly used in the field of health, from pedometers to blood sugar and blood pressure monitoring, and with the introduction of social platforms, the field of health services has been greatly expanded, allowing people to manage their health by encouraging each other, and personal health changes will become more favorable than before.
