Social marketing and communication: changing health behavior in the third world.
Abstract   Development communication, particularly within the health sector, is relatively new and still shrouded in mystique. Many health planners and policy-makers in developing countries and elsewhere do not yet fully appreciate the role communication plays in primary health care interventions. Nevertheless, communication theory, embracing diffusion of innovations and social marketing, can make a significant contribution in improving health status. This paper explores, through an examination of the literature and the experience of a worldwide research and development project, the synthesis of development communication, diffusion, social marketing, and primary health care. It attempts to demonstrate the value of integrating these paradigms within the context of a public health communication model. Focusing on the use of radio and interpersonal communication, the paper describes model projects in India and Honduras and reveals through their example the role of communication in changing health behavior in Third World settings.
