Reducing social inequalities in health: public health, community health or health promotion?

While the Consortium on 'Community Health Promotion' is suggesting a definition of this new concept to qualify health practices, this article questions the relevance of introducing such a concept since no one has yet succeeded in really differentiating the three existing processes: public health, community health, and health promotion. Based on a literature review and an analysis of the range of practices, these three concepts can be distinguished in terms of their processes and their goals. Public health and community health share a common objective, to improve the health of the population. In order to achieve this objective, public health uses a technocratic process whereas community health uses a participatory one. Health promotion, on the other hand, aims to reduce social inequalities in health through an empowerment process. However, this is only a theoretical definition since, in practice, health promotion professionals tend to easily forget this objective. Three arguments should incite health promoters to become the leading voices in the fight against social inequalities in health. The first two arguments are based on the ineffectiveness of the approaches that characterize public health and community health, which focus on the health system and health education, to reduce social inequalities in health. The third argument in favour of health promotion is more political in nature because there is not sufficient evidence of its effectiveness since the work in this area is relatively recent. Those responsible for health promotion must engage in planning to reduce social inequalities in health and must ensure they have the means to assess the effectiveness of any actions taken.
