Scientific evidence shows that physical inactivity is a leading risk factor for ill health, going well beyond issues related to weight control and influencing both physical and mental well-being. Over the past few years, the promotion of physical activity has increasingly been recognized in Europe as a priority for public health, and many countries have responded by developing policies and interventions. To support Member States’ efforts, the WHO Regional Office for Europe has developed a blueprint for making physical activity appealing to young people. It is intended to be a resource for physical-activity promoters, with a focus on supportive urban environments and settings where children and young people live, study and play. This report outlines the blueprint, its development and suggested next steps.
