Aim: To arrive at an international consensus on research priorities in the area of child and adolescent physical activity and sedentary behaviour. Methods: Two independent panels, each consisting of 12 experts, undertook three rounds of a Delphi methodology. The Delphi methodology required experts to anonymously answer questions put forward by the researchers with feedback provided between each round. Results: The primary outcome of the study was a ranked set of 29 research priorities that aimed to be applicable for the next 10 years. The top three ranked priorities were: developing effective and sustainable interventions to increase children’s physical activity long-term; policy and/or environmental change and their influence on children’s physical activity and sedentary behaviour; and prospective, longitudinal studies of the independent effects of physical activity and sedentary behaviour on health. Conclusions: These research priorities can help to guide decisions on future research directions.enPhysical activitySedentary behaviourResearch prioritiesChildrenAdolescentsArticleAttribution-NonCommercial-NoDerivs 2.5 CanadaSchool of Exercise Science, Physical and Health EducationDepartment of Psychology
