With the progress of social economy and science and technology, the current human health model and disease spectrum have undergone important changes; In the past, many infectious diseases that mainly endanger people's health in China have been eliminated or controlled, while some chronic non-communicable diseases, such as cardiovascular and cerebrovascular diseases (hypertension, stroke, coronary heart disease), malignant tumors, diabetes, mental disorders and accidental injuries, have become common and frequently-occurring diseases that threaten people's lives and health. Because the occurrence of these diseases is closely related to the unhealthy lifestyle and behavior habits of individuals, they are also called "lifestyle diseases". The fundamental way to prevent these diseases is to advocate self-care, change bad behavior habits and establish a scientific, civilized and healthy lifestyle.
