The health gap is a global problem. The World Health Organization (WHO) established the Committee on Social Determinants of Health in 2005, aiming at collecting evidence, finding out what actions can be taken to promote health equity, and promoting the launch of the global health equity movement, and using the concept of "social determinants of health" to explain the health gap between countries, regions within countries and even residents in the same city. The World Health Organization describes this concept as "the environment in which people are born, grow up, live, work and get old, and the system established to deal with diseases. These environments are in turn influenced by a series of broader forces, namely, economy, social policy and politics. " Therefore, almost all aspects of personal environment and living conditions will affect a person's health and quality of life. The National Health 2020 Initiative puts forward a framework of social determinants of health, including five key factors: economic stability, education, social and community environment, health and care, neighborhood and living environment, and identifies some key components or key issues in each field. Among these five key factors, the lack of economic resources will affect other resources and opportunities, such as paying university fees, healthy food, adequate housing, safe neighborhood relations, preventive health care and high-quality medical services. The resulting poor health makes it difficult for people to keep their jobs, continue their education and engage in other activities to break the spread of poverty. Economic factors, education, health status, neighborhood environment, community environment and other social decisive factors are interrelated and influential.
