People’s health is affected by social circumstances such as education, income, occupation, and their connections. It is also affected by national and regional policies, culture, economic trends, income disparity, and other social factors. Therefore, it is not possible to protect people’s health only with approaches that encourage individuals to take rational actions such as “exercise moderately” or “stop smoking”. Social epidemiology uses epidemiological methods to elucidate these “social determinants of health” and to control the health disparities that arise from them. Our goal is to create a society in which everyone can be naturally healthy.
