To describe new WHO 2020 guidelines on physical activity and sedentary behaviour.
The guidelines were developed in accordance with WHO protocols. An expert Guideline Development Group reviewed evidence to assess associations between physical activity and sedentary behaviour for an agreed set of health outcomes and population groups. The assessment used and systematically updated recent relevant systematic reviews; new primary reviews addressed additional health outcomes or subpopulations.
The new guidelines address children, adolescents, adults, older adults and include new specific recommendations for pregnant and postpartum women and people living with chronic conditions or disability. All adults should undertake 150-300 min of moderate-intensity, or 75-150 min of vigorous-intensity physical activity, or some equivalent combination of moderate-intensity and vigorous-intensity aerobic physical activity, per week. Among children and adolescents, an average of 60 min/day of moderate-to-vigorous intensity aerobic physical activity across the week provides health benefits. The guidelines recommend regular muscle-strengthening activity for all age groups. Additionally, reducing sedentary behaviours is recommended across all age groups and abilities, although evidence was insufficient to quantify a sedentary behaviour threshold.
These 2020 WHO guidelines update previous WHO recommendations released in 2010. They reaffirm messages that some physical activity is better than none, that more physical activity is better for optimal health outcomes and provide a new recommendation on reducing sedentary behaviours. These guidelines highlight the importance of regularly undertaking both aerobic and muscle strengthening activities and for the first time, there are specific recommendations for specific populations including for pregnant and postpartum women and people living with chronic conditions or disability. These guidelines should be used to inform national health policies aligned with the and to strengthen surveillance systems that track progress towards national and global targets.
描述世界卫生组织（WHO） 2020 年关于身体活动和久坐行为的新指南。
该指南是按照世卫组织的方案制定的。一个专家指导方针制定小组审查了证据，以评估身体活动和久坐行为与一系列商定的健康结果和人群之间的关系。评估使用并系统地更新了最近的相关系统评价；新的主要评价则针对其他健康结果或亚人群。
新指南涉及儿童、青少年、成年人和老年人，包括为孕妇和产后妇女以及患有慢性病或残疾的人提供新的具体建议。所有成年人每周应进行 150-300 分钟中等强度或 75-150 分钟剧烈强度的身体活动，或进行相当数量的中等强度和剧烈强度有氧运动的组合。对于儿童和青少年，每周平均进行 60 分钟的中等到剧烈强度有氧运动有益于健康。指南建议所有年龄段的人定期进行肌肉强化活动。此外，建议减少所有年龄段和能力的久坐行为，尽管证据不足以量化久坐行为的阈值。
这些 2020 年世卫组织指南更新了 2010 年发布的世卫组织先前建议。它们重申了一些身体活动总比没有好、更多的身体活动对最佳健康结果更好的信息，并提供了减少久坐行为的新建议。这些指南强调了定期进行有氧运动和肌肉强化活动的重要性，这是首次为包括孕妇和产后妇女以及患有慢性病或残疾的特定人群提供具体建议。这些指南应被用来为与《可持续发展目标》相一致的国家卫生政策提供信息，并加强跟踪各国和全球目标进展情况的监测系统。
