Within the World Café collaboration, the World Obesity Federation interviewed Prof Wolfgang Ahrens (BIPS) coordinator of the Policy Evaluation Network - PEN

The interview focuses on the prevalence of childhood obesity across Europe and the barriers to addressing this problem. Prof Ahrens also talks about how is the Policy Evaluation Network evaluating policy measures to promote a healthy diet and physical activity in Europe and how has the cross-collaboration with the STOP, CO-CREATE, and JA Best-ReMAP projects strengthened the efforts in doing so.
