[Complex management of partnerships during a health promotion campaign].

This article discusses an analysis of partnerships in the context of health promotion. The 5/30 Health Challenge, or "Défi Santé 5/30", is a campaign to promote healthy eating habits in Quebec. The authors employ this as a case study in order to 1) describe the actors and the nature of their involvement during the campaign's development, design and dissemination; 2) illustrate the interaction of these actors during the conceptualization and rollout of the campaign; 3) propose a paradigm that supports the identification of factors that contribute to or impede partner relationships.
