The Health Promotion Glossary, published by the World Health Organization (WHO) in 1986, was initially intended to clarify the meanings and relationships between various terms in health promotion. It has been translated into several languages and widely used within and outside WHO. The glossary was adapted and republished in German in 1990. Since its publication, significant developments in health promotion have occurred, including the Ottawa Charter for Health Promotion (1986), the Adelaide Conference (1988), the Sundsvall Conference (1991), and the Jakarta Conference (1997), which adopted the Jakarta Declaration on Leading Health Promotion into the 21st Century. These conferences have contributed to a better understanding of health promotion strategies and their practical application, especially for developing countries. Several WHO programs and projects have been developed to translate health promotion concepts into practical action, including the 'Healthy Cities, Villages, Municipalities' and 'Healthy Islands' projects, the networks of 'Health Promoting Schools' and 'Health Promoting Hospitals', and the 'Healthy Marketplaces and 'Health Promoting Workplaces' projects, as well as WHO action plans on alcohol and tobacco, active living, and healthy ageing. Recent developments in health systems have given new prominence to health promotion approaches, emphasizing the importance of health outcomes and the need for investment in the determinants of health through health promotion. The glossary has been revised to reflect the evolution of health promotion concepts and to include new terms. It consists of two sections: the first contains seven core definitions central to health promotion, and the second includes an extended list of 50 terms commonly used in health promotion. The glossary is intended to facilitate communication between countries and within countries, as well as among various agencies and individuals working in the field. The definitions are not considered final and may be revised as new information becomes available. The glossary includes definitions of key terms such as health, health promotion, health for all, public health, primary health care, disease prevention, health education, advocacy for health, alliance, community, community action for health, determinants of health, empowerment for health, enabling, epidemiology, equity in health, health behaviour, health communication, health development, health expectancy, health gain, health goal, health indicator, health literacy, health outcomes, health policy, health promoting hospitals, health promoting schools, health promotion outcomes, health promotion evaluation, health sector, health status, health target, healthy cities, healthy islands, healthy public policy, infrastructure for health promotion, intermediate health outcomes, intersectoral collaboration, investment for health. Each term is defined to reflect its application in the context of health promotion and is intended to clarify the key terminology and support the development of health promotion strategies and practical action.The Health Promotion Glossary, published by the World Health Organization (WHO) in 1986, was initially intended to clarify the meanings and relationships between various terms in health promotion.
