Global level physical activity surveillance studies were primarily based on self-report data that could generate inaccurate results.
To investigate global accelerometer-measured daily moderate to vigorous physical activity (MVPA) changes from preschool age to adolescence as well as gender differences in MVPA while adjusting for the geographic regions and major MVPA cut points.
A comprehensive search was conducted through August 2020 that includes 30 databases such as Academic Search Ultimate, Child Development & Adolescent Studies, Education Full Text, ERIC, General Science, PsycINFO, ScienceDirect, and SPORTDiscuss. We included both cross-sectional and longitudinal MVPA tracking studies with daily MVPA being measured by waist-worn accelerometers and determined by either Freedson 3 METs, 4 METs, or Evenson cut points for preschoolers, children, and adolescents.
Researchers analyzed 84 studies reporting on 124 effect sizes with a total of 57,587 participants. The combined data showed significant MVPA differences among various continents of participants (p < .001) or cut points (p < .05-.001) for both preschoolers, children, and adolescents. Globally, when continents and cut points were controlled, individuals' daily MVPA time decreased every year by an average of 7.88, 10.37, and 6.68 min from preschool age to adolescence, preschool age to children, and children to adolescence, respectively. When cut points and continents were controlled, boys had significantly higher daily MVPA than girls for all three age groups (p < .001).
Globally, individuals' daily MVPA starts to decline dramatically as early as the beginning of preschool age. Early intervention is needed to counteract the high decline rate in MVPA.
全球层面的身体活动监测研究主要基于自我报告数据，这些数据可能产生不准确的结果。
调查从学前到青春期期间全球加速度计测量的日常中等到剧烈身体活动（MVPA）变化，以及在调整地理区域和主要 MVPA 切点的情况下 MVPA 的性别差异。
通过 2020 年 8 月进行的全面搜索，包括 30 个数据库，如 Academic Search Ultimate、儿童发展与青少年研究、教育全文、ERIC、综合科学、PsycINFO、ScienceDirect 和 SPORTDiscuss。我们纳入了横断面和纵向 MVPA 追踪研究，使用腰部佩戴的加速度计测量每日 MVPA，并通过 Freedson 3 METs、4 METs 或 Evenson 切点确定学龄前儿童、儿童和青少年的 MVPA。
研究人员分析了 84 项研究报告，共涉及 124 个效应量，共有 57587 名参与者。综合数据显示，参与者来自不同大洲（p <.001）或切点（p <.05-.001）时，MVPA 存在显著差异，无论是学龄前儿童、儿童还是青少年。在全球范围内，当控制大洲和切点时，个体每天的 MVPA 时间从学前到青春期、学前到儿童期和儿童到青春期分别平均减少 7.88、10.37 和 6.68 分钟。当控制切点和大洲时，男孩在所有三个年龄组的每日 MVPA 均显著高于女孩（p <.001）。
从学前年龄开始，全球范围内个体的日常 MVPA 开始急剧下降。需要早期干预来对抗 MVPA 的高下降率。
