Now in its third edition, this textbook serves to frame understandings of health, health-related behavior, and health care in light of social and health inequality as well as structural violence. It also examines how the exercise of power in the health arena and in society overall impacts human health and well-being. Medical Anthropology and the World System: Critical Perspectives, Third Edition includes updated and expanded information on medical anthropology, resulting in an even more comprehensive resource for undergraduate students, graduate students, and researchers worldwide. As in the previous versions of this text, the authors provide insights from the perspective of critical medical anthropology, a well-established theoretical viewpoint from which faculty, researchers, and students study medical anthropology. It addresses the nature and scope of medical anthropology; the biosocial and political ecological origins of disease, health inequities, and social suffering; and the nature of medical systems in indigenous and pre-capitalist state societies and modern societies. The third edition also includes new material on the relationship between climate change and health. Finally, this textbook explores health praxis and the struggle for a healthy world.
