Book excerpt: The World Mental Health Surveys were established by the World Health Organization in 2000 to provide valuable information for physicians and health policy planners. These surveys have shed light on the prevalence, correlates, burden, and treatment of mental disorders in countries throughout the world. This volume focuses on the epidemiology of coexisting physical and mental illness around the world. This book includes surveys from 17 discrete countries on six continents, covering epidemiology, risk factors, consequences, and implications for research, clinical work, and policy. Many physical and mental illnesses share a relationship with one another and often occur simultaneously. Clinicians from the disciplines of both psychiatry and medicine are increasingly faced with both challenges on a daily basis, making this an ideal book for a wide range of health professionals. This is the first book devoted to this topic on such a wide-ranging scale.
