[Integrating prevention and promotion in health systems: four realities, diverse similarities]. / L'intégration de la prévention et de la promotion dans les systèmes de santé: quatre réalités, plusiers similitudes.

The Forum Dialogue on national health systems which took place as a satellite meeting of the 2nd International Conference on Local and Regional Health Programmes compared four countries (Brazil, France, Switzerland and Canada) sustain "conditions to integrate prevention and promotion in health systems". Despite the diversity of the four systems presented, several similarities regarding difficulties faced and achievements obtained in the integration process have been extracted, which has allowed highlighting three perspectives of action. It is suggested that prevention and promotion can be integrated into health systems by mobilising the population and health professionals towards prevention, but with the condition that the promotion and prevention sector increase its credibility by developing practices of quality, organisation, discourse, and prevention practices adjusted to the health care context. Finally, exchange between the countries on this subject is the way forward to nourish the thinking and support each other to obtain this desired integration.
