Medical sociology may very well seem to be an abstract topic at first glance. However, it has vast implications in the field of health care and is an integral part of the medical system. According to the American Sociological Association, medical sociology “provides an analytical framework for understanding the social contexts of health, illness and health care. Central topics include the subjective experience of health and illness, political, economic and environmental circumstances fostering ill health; and societal forces constraining the medical care system and individuals' responses to illness. This field draws on traditional sociological issues and contributes to them through reformulations of such basic concepts as social systems and institutions, professionalism, social movements and social change, and social interaction and negotiation. Drawing from pluralistic perspectives, the field is concerned with basic sociological research and its implications for public policy and practice.” The range of topics covered by medical sociology can include specific cultures’ health policies and practices, religious differences in approaches to medicine, and disparities faced by certain ethnic groups.
