This stimulating book has become a go-to text for understanding the role that social factors play in the experience of health and many diseases. This extensively revised and updated third edition offers the most compelling case yet that stress, poverty, unhealthy lifestyles, and unpleasant living and working conditions can all be directly associated with illness. The book continues to build on the paradigm shift that has been emerging in twenty-first-century medical sociology, which looks beyond individual explanations for health and disease. As the field has headed toward a fundamentally different orientation, William Cockerham’s work has been at the forefront of these changes, and he here marshals evidence and theory for those seeking a clear and authoritative guide to the realities of the social determinants of health. Of particular note in the latest edition is new material on the relationship between gender and health, implications of the life course for health behavior,  the health effects of social capital, and the emergence of COVID-19. This engaging introduction to social epidemiology will be indispensable reading for all students and scholars of medical sociology, especially those with the courage to confront the possibility that society really does make people sick.
