Abstract
Social epidemiology is a study that explores the social factors or social phenomena that impact population health. It incorporates the concepts and methods of population health. This chapter focuses on social epidemiology as a research method in the context of population health. The significant role of social epidemiology in examining the influence of social determinants on the health of individuals and groups is emphasized. Concepts, theories, and methods of social epidemiological research are explored to explicate the influence of complex social factors on the health of populations. The implications for research and translation of evidence of social epidemiology into practice, curriculum, and policy development are discussed.
