The determinants of health: structure, context and agency.

The concept of social structure is one of the main building blocks of the social sciences, but it lacks any precise technical definition within general sociological theory. This paper reviews the way in which the concept has been deployed within medical sociology, arguing that in recent times it has been used primarily as a frame for the sociological interpretation of health inequalities and their social determinants. It goes on to examine the contribution that medical sociologists have made to the debate over health inequalities, giving particular attention to contributions to Sociology of Health and Illness. These have often provided a focus for discussions outside or critical of the mainstream debates that have been driven primarily by epidemiologists. The paper reviews some of the main points of criticism of epidemiological approaches, focusing in particular on the methodological constraints that limit the capacity of epidemiologists to develop more theoretically satisfactory accounts of the inter-relationships of social structure, context and agency in their impact on health and well being. Some recent examples from the Journal of more theoretically innovative and analytically fine-grained approaches to understanding the impact of social structure on health are then explored. The paper concludes with an argument for a more historically-informed analysis of the relationships between social structure and health, using the knowledgeable narratives of people in places as a window onto those relationships.
