Communication and health — health as an ecosystem

Abstract

The importance of communication in public health is described with reference to recent experiences in Australia where good progress has been made with certain major public health problems. There has been a 30% fall in road accident deaths and a 40% fall in deaths from coronary heart disease, and a smoke free environment has been established in public places and in the work place. These successes depended on effective communication based on appropriate data. Evaluation data have also been used to keep the public informed and to reinforce the message. The cooperation of the media has been most important in stimulating a new awareness of health and the opportunities for self help and community initiatives. In central Australia, new initiatives involving the Central Australian Aboriginal Congress have led to an improvement in the health of Aborigines, the training of Aborigines as health workers and the development of a Centre for Appropriate Technology at the Alice Springs College of Technical and Further Education. At the international level, Australia sponsored a World Health Assembly resolution in 1986 calling for the elimination of iodine deficiency disorders. With the support of the Australian International Development Assistance Bureau and the United Nations Children's Fund (UNICEF), an international expert group of scientists and public health professionals, the International Council for Control of Iodine Deficiency Disorders (ICCIDD), based in Adelaide, has been able to work with the World Health Organization (WHO) and UNICEF in the development of an international public health programme aimed at eliminating iodine deficiency disorders by the year 2000. The ICCIDD is a new model for communication and action in international health which is now being advocated for other areas.
