世界卫生组织 (WHO) 于 2020 年发布了关于儿童、青少年、成人、老年人以及孕妇和产后妇女以及慢性病或残疾患者等亚人群的身体活动和久坐行为的最新全球指南。总结身体活动、久坐行为和健康相关结果之间关联的证据，用于为 2020 年世界卫生组织 5-17 岁儿童和青少年身体活动和久坐行为指南提供信息。世卫组织儿童和青少年指南建议的更新利用并系统更新了针对 2016 年加拿大儿童和青少年 24 小时运动指南、2019 年澳大利亚儿童和青少年 24 小时运动指南（5-17 岁）和 2018 年美国身体活动指南第二版进行的身体活动和久坐行为的证据综合。确定了 2017 年至 2019 年 7 月发表的针对关键问题的系统评价，并使用建议评估、制定和评价分级 (GRADE) 框架对整个证据体系的证据确定性进行评级。更新的文献检索产生了 21 篇相关的系统综述。审查的证据基础（即现有的和新的系统审查）提供的证据表明，更大数量和更高强度的身体活动以及不同类型的身体活动（即有氧运动和肌肉和骨骼强化活动）与改善的健康结果（主要是中间结果）相关。有足够的证据支持关于限制久坐行为的建议，而 2010 年世界卫生组织指南中并未提及这一点。然而，仍然没有足够的证据来充分描述体力活动或久坐行为与健康结果之间的剂量反应关系，以及这种关联是否因体力活动或久坐行为的类型或领域而异。解决已确定的研究差距将更好地为儿童和青少年提供指导建议，未来的工作应优先考虑这些研究领域。与此同时，需要投资和领导力来扩大旨在增加儿童和青少年活动的已知有效政策和计划。
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. 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. 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. 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. 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.
