Nursing's traditional concern for human well being includes concern for health promotion. Until recently textbooks of preventive medicine, public health and community health nursing have defined health prevention-the prevention of disease and health protection or maintenance, but not health promotion. Lack of clear definitions inhibit effective communication among health related disciplines. Therefore, this study's task was the analysis and definition of the concept of health promotion using walker & Avant's concept analysis methodology. This characteristics of the concept of health promotion are 1) orientation toward well-being, 2) empowering, 3) subjectivity, 4) change and 5) expanded connective. Antecedent of health promotion are 1) attaining of a health state, 2) having purpose and will to act, 3) persistent and realistic behaviour. The consequences of health promotion are 1) prolonged life, 2) self-actualizing potential, 3) increased well-being and a high level quality of life. The future direction of health promotion research should include that identification of the differences in the definition of between health professionals and health clients and research related to nursing theory of health promotion.
