Physical inactivity and childhood obesity are well-recognized public health concerns that are associated with a range of adverse health outcomes. Historically, the benefits of physical activity (e.g., moderate-to-vigorous physical activity-MVPA) to overall health have dominated discussions and emerging evidence indicates that a broader, more integrated approach is needed to better understand and address current public health crises. Existing guidelines for children and youth around the world only focus on MVPA, and recently sedentary behavior, despite an accumulating body of evidence showing that light-intensity physical activity (LPA) such as walking can provide important health benefits. Furthermore, there is accumulating support for the importance of adequate sleep and that these behaviors moderate the health impact of each other. Ignoring the other components of the movement continuum (i.e., sleep, sedentary time, LPA) while focusing efforts exclusively on MVPA (accounting for <5% of the time in a 24 h period) limits the potential to optimize the health benefits of movement behaviors. In order to address this limitation, experts in Canada are currently developing the world's first Integrated 24 Hour Movement Behaviour Guidelines for Children and Youth to help advance an integrated healthy active living agenda that has the potential to significantly improve the overall health and well-being of children and youth.
缺乏身体活动和儿童肥胖是公认的公共卫生问题,与一系列不良健康后果相关。从历史上看,身体活动(如中度至剧烈身体活动——MVPA)对整体健康的益处主导了相关讨论,而新出现的证据表明,需要一种更广泛、更综合的方法来更好地理解和应对当前的公共卫生危机。尽管越来越多的证据表明,像步行这样的低强度身体活动(LPA)能带来重要的健康益处,但世界各地现有的儿童和青少年指南仅关注MVPA,最近才开始关注久坐行为。此外,越来越多的证据支持充足睡眠的重要性,而且这些行为会相互调节对健康的影响。在仅专注于MVPA(占24小时时长的不到5%)的同时忽略运动连续体的其他组成部分(即睡眠、久坐时间、LPA),限制了优化运动行为对健康益处的潜力。为了解决这一限制,加拿大的专家目前正在制定世界上首个《儿童和青少年24小时运动行为综合指南》,以推动一项综合的健康积极生活议程,该议程有可能显著改善儿童和青少年的整体健康和福祉。
