[Intensify the development of public policy has the health: approaches strategic for the authorities of health public].

Health promotion is one of the essential functions of public health authorities. The first pillar of health promotion is the elaboration of healthy public policy. Using the theoretical foundations of the healthy public policy concept, it can be demonstrated that public health authorities are able to develop, at their own scale, healthy public policies. Three strategic approaches are proposed in order to support public health authorities in strengthening their healthy public policy actions. First, better understand the tools or policy instruments (economic, regulation, information and persuasion) at their disposal. Second, take stock of the many types of legitimacy (theoretical, legislative, administrative and scientific) available to public health authorities as they develop healthy public policy. Third, consider the potential scientific roles that can be adopted while using the various policy instruments. These approaches can represent a pragmatic and structuring support for public health authorities wanting to strengthen their healthy public policy actions.
