To achieve our overall aim of reducing the prevalence of obesity among adolescents in Europe through policy actions to promote a healthier food and physical activity environment, we have organised our work into 10 work packages (WP1 – WP10), where WP 10 is an internal work structure with no public dissemination.

The CO-CREATE study aims to prevent overweight and obesity in adolescents by providing knowledge and infrastructure on policies to support making the healthiest choices the preferred ones.

CO-CREATE project organisation

WP 1: Project management and coordination

The overall objective of WP 1 is to establish and maintain a robust management structure to ensure that all CO-CREATE work and deliverables are realised on schedule, within budget and within all relevant ethical and legal framework.

WP 1 leader is Knut-Inge Klepp (Norwegian Institute of Public Health).

Key deliverables from this WP include:

  • D 1.2: Establishment and maintenance of our Science, Policy and Ethics advisory board (SPEAB)
  • D 1.4: Strategy for ethics, gender and youth involvement
  • D 1.5: Project quality assurance plan

WP 2: Policy assessment and monitoring

The overall objective of WP 2 is to develop a policy monitoring tool for physical activity, building on the existing NOURISHING framework of World Cancer Research Fund International, and conduct global scans of implemented policies promoting healthy diets and physical activity. Furthermore, WP 2 will develop an index to benchmark and assess the overall policy status with regards to physical activity in Europe.

WP 2 leader is Louise Meincke (World Cancer Research Fund International)

Key deliverables from this WP include:

  • D 2.2: Article outlining the developed physical activity policy framework
  • D 2.4: Article outlining the challenges faced by conduction the policy scan
  • D 2.4: Physical activity policy database
  • D 2.9: Article summarising the development of the policy benchmarking criteria and policy index
  • D 2.10 and D 2.12: Policy briefs on the effects of implemented policies and policy outputs

WP 3: Obesity rates and energy balance related behaviours

The overall objective of WP 3 is to establish the state of the art in terms of existing evidence regarding effective measures to prevent overweight and obesity among adolescents. This WP will also investigate changes in overweight and obesity rates and energy balance related behaviours across countries over time, and specifically study the relation to relevant policies. 

WP 3 leader is Arnfinn Helleve (Norwegian Institute of Public Health)

Key deliverables from this WP include:

  • D 3.1: Systematic review of systematic reviews 
  • D 3.2: Report on time trends and differences in obesity rates based on data from COSI
  • D 3.4: Report on time trends and differences in energy balance-related behaviour, overweight and obesity rates based on HBSC
  • D 3.6: Report on observed changes in energy balance-related behaviour, overweight and obesity in relation to national diet and physical activity policies
  • D 3.7: Policy brief based on analyses of existing data on effective strategies for targeting adolescents.

WP 4: Obesity system mapping

The overall objective of WP 4 is to identify the key factors driving obesity in adolescents and generate system maps to identify the key opportunities for policy interventions to tackle the problem of adolescent obesity. The views of the adolescents themselves, as well as academic experts and policy makers will be included. 

WP 4 leader is Cecile Knai (London School for Hygiene and Tropical Medicine)

Key deliverables from this WP include:

  • D 4.1: A set of conceptual system maps of the drivers of energy balance-related behaviours.
  • D 4.2: Overall conceptual model of the factors driving obesity among adolescents in Europe.
  • D 4.3: Outline of prioritised set of potentially important policy levers based on the system maps.
  • D 4.5: Report describing obesity system structures.
  • D 4.6: Country specific system maps, and synthesised master map. 

WP 5: Youth Alliances for Overweight Prevention Policies

The overall objective of WP 5 is to inform and develop novel, context specific and evidence based policy options for obesity prevention through involvement and participation of youth from diverse background across Europe. Transferable Youth Alliances for Overweight Prevention Policies will be established in several countries to allow for exchange of knowledge between researchers and adolescents, integrating experiential, scientific and political knowledge to promote upstream prevention overweight prevention across Europe.

WP 5 leader is Christian Bröer (University of Amsterdam)

Key deliverables from this WP include:

  • D 5.2: Establishment of the Youth Alliances for Overweight Prevention Policies in five countries across Europe
  • D 5.3: Proposals for new policy prepared in collaboration with the Youth Alliances
  • D 5.4: Video documentation of Youth Alliance work
  • D 5.5: Evaluation reports on the Youth Alliances

WP 6: Dialogue forums

The overall objective of WP 6 is to bring together adolescents, policy makers and businesses to produce actionable commitments to enable healthy nutrition and physical activity habits for obesity prevention. A model for dialogue forums, scaled and owned by adolescents themselves, to drive and engage this constructive multi-actor dialogue will be developed.

WP 6 leader is Sudhvir Singh (EAT Foundation)

Key deliverables from this WP include:

  • D 6.1: Development prototype dialogue forum
  • D 6.4: Hold dialogue forums across Europe
  • D 6.5: Produce reports on the actions and commitments decided in the forums
  • D 6.6: Recommendation on how to establish multi-actor dialogue forums

WP 7: Evaluation of CO-CREATEd policy interventions and methodology

The overall objective of WP 7 is to evaluate the CO-CREATion, using process, output and impact data. Evaluation will be conducted using both quantitative and qualitative data, as well as an adaptable systems dynamics core model to simulate potential effects of obesity related policy interventions. 

WP 7 leader is Nanna Lien (University of Oslo)

Key deliverables from this WP include:

  • D 7.3: Develop a systems dynamics model
  • D 7.4: Develop project implementation an evaluation plans
  • D 7.7: Develop questionnaire for measuring attitudes and readiness for action towards policy measures to combat childhood obesity

WP 8: Open science and fair data management

The overall objective of WP 8 is to ensure high level quality of data collected in the project through systematic and documented data management, including procedures for sampling and collection of data. Included is also the management of open research data in line with the EU Open Research Data Pilot (lenke).

WP 8 leader is Oddrun Samdal (University of Bergen)

Key deliverables from this WP include:

  • D 8.1: Data management plan 
  • D 8.4: Open access data with documentation

WP 9: Dissemination, communication and exploitation of project results

The overall objective of WP 9 is to develop a plan for dissemination and communication of project activities and results, and exploitation of key results beyond the project period. This WP will ensure continuous dissemination and communication of project results to various stakeholder groups, including academia, policy makers, businesses and youth themselves.

WP 9 leader is Tim Lobstein (World Obesity Federation)

Key deliverables from this WP include:

  • D 9.1: Dissemination, exploitation and communication strategy and operational plan
  • D 9.3: Intellectual property strategy 

WP 10: Ethics requirements

WP 10 will monitor and advice on the proper implementation and follow up of project adherence to best practice research ethics, and monitor that the project obtains all legal permissions in a timely manner.
