Medical Anthropology: A Biocultural Approach, Fourth Edition, offers an accessible and contemporary overview of this rapidly expanding field. For each health issue examined in the text, the authors first present basic biological information and then expand their analysis to include evolutionary, historical, and cross-cultural perspectives on how these issues emerged and are understood. Medical Anthropology considers how a biocultural approach can be applied to more effective prevention and treatment efforts and underscores medical anthropology's potential to improve health around the world.
