Health Promotion: Historical Evolution. Health promotion is not a new concept. The fact that health is determined by factors not only within the health sector but also by factors outside was recognized long back.
The World Health Organization (WHO) defines health promotion as a process of enabling people to increase control over and to improve their health. To facilitate that process, we must provide people with appropriate information. Nurses have a key role in providing that information in the form of health teaching. Nurses are highly educated, experienced health professionals who are accessible through many settings such as hospitals.
