2.K. Skills building seminar: Nutrition: A Challenge For The Intervention Research And Health Promotion

Cancer is the leading cause of death in Europe, the second in North America and it's estimated that 40% of cancers are preventable. Among these cancers, it's estimated that 10,8% are attributable to unbalanced diet (5.4%) and overweight (5,4%), and in addition, a smaller proportion is attributable to lack of physical activity (0,9%). In France, it's estimated that one in two people is overweight and particular attention is paid to young people. It's recognised that the risk of cancer can be reduced when the risk factor is known and acted upon: experience has shown that this knowledge is necessary but insufficient to know how to act. Population health intervention research (PHIR), a “solutions” science, fills this gap. It's concerned with the design, implementation, evaluation, adaptation, transferability and sustainability of interventions aimed at improving the health of populations, in order to produce valid knowledge with high potential for social and health impacts. This scientific approach apprehends interventions as “events in systems” and challenges the methodological hegemony imposed for many years by the biomedical sciences and especially epidemiology approach. Finally, this approach follows to act and intervene with and for the targeted populations, particularly people in vulnerable situations. Today, the development of PHIR in health promotion and in the field of cancer on the topic of nutrition, faces three major challenges: - Political; - Methodology; - Transferability. It's therefore proposed to give three complementary presentations directly addressing these issues on the topic of nutrition, each based on concrete examples of implementation in health promotion and in the field of cancer. The aim of this workshop is to offer a time for exchange and discussion on the challenges to be met in developing PHIR in health promotion - on the topic of nutrition - as an innovative model of research within an innovative paradigm shift. It will enable participants to clarify their conceptions of PHIR for the advancement of health promotion in oncology and to evolve these concepts in relation to these three key issues. An interactive format is proposed, including time for discussion based on participants’ perceptions and time for presentations. KEY MESSAGES: • PHIR: an effective scientific approach and a relevant tool for thinking about and developing health promotion policies on the topic of nutrition. • New research paradigm in health promotion and the fight against cancers, particularly linked to unbalanced diet and overweight, based on intervention with populations to act on the determinants of health.
