Focusing on universal public health issues, this book explores what can be done and what the future holds. It introduces students and practitioners to behavior -change theories and applications. It details experiences of successful programs for the prevention and control of the world's biggest killers: malnutrition; respiratory infections; diarrhea; HIV//AIDS; and health problems arising from tobacco consumption and lack of access to family planning. The book explores health communication and social marketing strategies, learning theory, media advocacy, and community development. These behavior-change strategies are presented in terms of how the theory relates specifically to a particular health or disease issue.
