Systematic reviews of evidence prepared for the 2018 US Physical Activity Guidelines Advisory Committee Scientific Report to the Secretary of Health and Human Services were updated thanks to additional literature searches conducted by Kyle Sprow (National Cancer Institutes, National Institutes of Health, Maryland, USA). Summaries of evidence and GRADE tables were prepared by Carrie Patnode and Michelle Henninger (The Kaiser Foundation Hospitals, Center for Health Research, Portland, Oregon, USA). This evidence reviews reported here were prepared for and funded by the World Health Organization. This work was submitted to the Guideline Development Group and considered as they formulated their recommendations. The authors also acknowledge the contribution of all other members of the Guideline Development Group in the review and drafting process.
Funding Information:
The Public Health Agency of Canada and the Government of Norway provided financial support to update the WHO guidelines on physical activity and sedentary behaviour. JPC is partly funded by the Canadian Institutes of Health Research and the CHEO Research Institute. UE is partly funded by the Research Council of Norway (249932/F20). JF is currently supported by a University of Manchester Presidential Fellowship (P123958) and a UK Research and Innovation Future Leaders Fellowship (MR/T021780/1) and has received support from a NICM-Blackmores Institute Fellowship. RJ is partly funded by National Institute for Health Research Applied Research Collaboration West (NIHR ARC West) at University Hospitals Bristol NHS Foundation Trust and the University of Bristol. FBO research activity is supported by the Spanish Ministry of Economy and Competitiveness (DEP2016–79512-R, and DEP2017–91544-EXP), the University of Granada, Research and Knowledge Transfer Fund (PPIT) 2016, the Excellence Actions Programme: Units of Excellence; Scientific Unit of Excellence on Exercise and Health (UCEES), the Andalusian Regional Government, the Regional Ministry of Economy, Knowledge, Enterprises and University, and the European Regional Development Fund (ERDF), ref.

N2 - Background: The World Health Organization (WHO) released in 2020 updated global guidelines on physical activity and sedentary behaviour for children, adolescents, adults, older adults and sub-populations such as pregnant and postpartum women and those living with chronic conditions or disabilities. Objective: To summarize the evidence on the associations between physical activity, sedentary behaviour, and health-related outcomes used to inform the 2020 WHO guidelines on physical activity and sedentary behaviour for children and adolescents aged 5–17 years. Methods: The update of the WHO guideline recommendations for children and adolescents utilized and systematically updated the evidence syntheses on physical activity and sedentary behaviour conducted for the 2016 Canadian 24-Hour Movement Guidelines for Children and Youth, the 2019 Australian 24-Hour Movement Guidelines for Children and Young People (5–17 years), and the 2018 Physical Activity Guidelines for Americans, Second Edition. Systematic reviews published from 2017 up to July 2019 that addressed the key questions were identified, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework was used to rate the certainty of the evidence for the entire body of evidence. Results: The updated literature search yielded 21 relevant systematic reviews. The evidence base reviewed (i.e., existing and new systematic reviews) provided evidence that greater amounts and higher intensities of physical activity as well as different types of physical activity (i.e., aerobic and muscle and bone strengthening activities) are associated with improved health outcomes (primarily intermediate outcomes). There was sufficient evidence to support recommendations on limiting sedentary behaviours, which was not addressed in the 2010 WHO guidelines. However, there is still insufficient evidence available to fully describe the dose-response relationships between physical activity or sedentary behaviour and health outcomes, and whether the associations vary by type or domain of physical activity or sedentary behaviour. Conclusions: Addressing the identified research gaps will better inform guideline recommendations in children and adolescents, and future work should aim to prioritize these areas of research. In the meantime, investment and leadership is needed to scale up known effective policies and programs aimed at increasing activity in children and adolescents.
