2 Logic model for interventions MODERATORS Ethnicity, socio-cultural factors, gender, age, SES = Measured = Modelled INPUTS Intervention Dose 1 Community capacity 2 Knowledge, attitudes, beliefs, perceptions etc INDIVIDUAL MEDIATORS OUTCOMES Behaviours Anthropometry 4 POPULATION MEDIATORS Environments 3 QoL Policy 1 Intervention dose is either 1 or 0 (intervention, control) or $$ (economic input all schools) 2 Capacity is leadership, skills/knowledge, structures, resources 3 Relevant environments are schools, homes, neighbourhoods, churches 4 Weight, BMI, BMI-z, waist, waist:height, %fat, prevalence of o/w+obesity QALYs gained

3 Top Down Approach Surveillance Mass Media/Education Assured Nutrition Services Policy Resources Local media, Education Local programs, Nutrition Services Environmental Changes Partnerships and Resource Identification Community Organization Bottom-up Approach Pearson TA, Wall S, Lewis C, Jerkins P, Nafziger A, Weinehall L.

4 The pillars of the EPODE methodology A professional structure to lead the programme (National Coordination Team) and manage 4 key components: Strong political support At both national and local levels (Ministries, mayors ) Social Marketing approach and network creation among local stakeholders, supported by a well-framed communication strategy EPODE National Coordination Team Independent Scientific expertise Collaboration with experts from different fields : scientific validation of messages, monitoring and evaluation Public / Private partnerships Designed and managed in collaboration with public, technical, scientific and private partners

30 Where are the key problems that we may face in the next decade (greatest challenges)? sustainable political commitment sustainable public-private partnerships funding for quantitative and qualitative evaluation affordable local health care

31 Where are the roadblocks (greatest difficulties)? short-term political interests versus long-term health goals multisectoral approaches difficult of insufficient cocreation of values for various sectors infrastructure and funding for long-term qualitative and quantitative evaluations commercial pressures that undermine healthy choices political pressures to stress individual responsibility

32 What societal impact might the outcomes of this research have? Effective integrated sustainable approaches for healthier lifestyles have many other benefits (education, safety, social integration, productivity, environment). Lower demands on health care. Improved quality of Life and societal participation

33 Recommendations for the future of European obesity research. Frameworks and research-tools for the quantitative and qualitative evaluation of integrated approaches (can also be used for other societal problems). Multidiciplinary research teams are needed. Roadmaps for the development of multisectoral and multistakeholder approaches. Effective interventions, effective implementation and effective integration.

34 European Obesity Research Conference: Thematic Recommendations Public health and prevention Develop frameworks for effective implementation and integration of interventions (including sustainable public-private partnership and sustainable political commitment) and research tools for quantitative and qualitative evaluation of integrated approaches. Develop capacity building through multisectoral action Determine characteristics of favourable environments for all ages (especially for physical activity promotion) and key interactions of environment with perceptions of environments and personal/social determinants Assess the impact on obesity of the changing economic climate and the impact on inequalities of interventions Develop a pan-european surveillance system of obesity, its causes and consequences
