Sociologists working in the area of health comprise one of the largest sociological specialties in the world. The field has expanded globally in response to growing recognition of the significant role of social factors in determining the health of individuals, groups, and populations. Ultimately, what allows health sociology to retain its unique character is (1) its utilization and mastery of sociological theory in the study of health and (2) the sociological perspective that accounts for collective causes and outcomes of health problems and issues. Today it can said that health sociology produces literature intended to inform medicine and policymakers, but research in the field is also grounded in examining health-related situations that inform sociology as well. This paper will briefly review the origins of health sociology and outline the transition to its current status before discussing the most recent developments in research techniques and the likely future direction of the field.
