Health promotion, as the name suggests, is a public campaign by a governnment to help educate the population at-large of the factors deemed important and necessary in promoting an optimal attainment of health. It is an effort to motivate the members of a governed population to take more responsibility in making decisions about the type of lifestyle they lead to promote good health. Evidence-based health promotion would be the same thing based upon empirical evidence gathered by scientists or pollsters that would tend to support those decisions made by the government. A good example would be the decision of cigarette smoking causing lung cancer and other respiratory-linked illnesses. Many state governments have filed lawsuits against the major tobacco companies in an effort to get the companies to identify the fact their product has been linked to several types of cancer, reducing public consumption of that product.
