Introducing Medical Anthropology: A Discipline in Action, provides students with a first look at the growing field of medical and health anthropology. The narrative is guided by three unifying themes. First, health-oriented anthropologists are involved in the process of helping to change the world around them through their work in applied projects, policy initiatives, and advocacy. Second, the authors present the fundamental importance of culture and social relationships in health and illness by demonstrating that illness and disease involve complex biosocial processes and that resolving them requires attention to a range of factors beyond biology. Third, through an examination of the issue of health inequality, this book underlines the need for an analysis that moves beyond cultural or even ecological models of health toward a comprehensive biosocial approach. Such an approach integrates biological, cultural, and social factors in building unified theoretical understandings of the origin of ill health, while contributing to the building of effective and equitable national health-care systems.
