Levels of physical activity and variation in physical activity and sedentary time by place and person in European children and adolescents are largely unknown. The objective of the study was to assess the variations in objectively measured physical activity and sedentary time in children and adolescents across Europe. Six databases were systematically searched to identify pan-European and national data sets on physical activity and sedentary time assessed by the same accelerometer in children (2 to 9.9 years) and adolescents (≥10 to 18 years). We harmonized individual-level data by reprocessing hip-worn raw accelerometer data files from 30 different studies conducted between 1997 and 2014, representing 47,497 individuals (2–18 years) from 18 different European countries. Overall, a maximum of 29% (95% CI: 25, 33) of children and 29% (95% CI: 25, 32) of adolescents were categorized as sufficiently physically active. We observed substantial country- and region-specific differences in physical activity and sedentary time, with lower physical activity levels and prevalence estimates in Southern European countries. Boys were more active and less sedentary in all age-categories. The onset of age-related lowering or leveling-off of physical activity and increase in sedentary time seems to become apparent at around 6 to 7 years of age. Two third of European children and adolescents are not sufficiently active. Our findings suggest substantial gender-, country- and region-specific differences in physical activity. These results should encourage policymakers, governments, and local and national stakeholders to take action to facilitate an increase in the physical activity levels of young people across Europe.

加速度计的变化测量了整个欧洲的体力活动和久坐时间——对 47,497 名儿童和青少年进行了协调分析。

欧洲儿童和青少年的身体活动水平以及身体活动和久坐时间的变化在很大程度上是未知的。该研究的目的是评估欧洲儿童和青少年客观测量的身体活动和久坐时间的变化。对六个数据库进行了系统搜索,以确定泛欧和国家数据集,这些数据集是由同一加速度计在儿童(2 至 9.9 岁)和青少年(≥10 至 18 岁)中评估的身体活动和久坐时间。我们通过重新处理 1997 年至 2014 年间进行的 30 项不同研究的髋部原始加速度计数据文件来协调个人水平数据,这些研究代表来自 18 个不同欧洲国家的 47,497 人(2-18 岁)。总体而言,最多 29% (95% CI: 25, 33) 的儿童和 29% (95% CI: 25, 32) 的青少年被归类为足够的体力活动。我们观察到身体活动和久坐时间在特定国家和地区的显着差异,南欧国家的身体活动水平和患病率估计值较低。在所有年龄段,男孩都更活跃,久坐不动。与年龄相关的体力活动降低或趋于平稳以及久坐时间增加的开始似乎在 6 至 7 岁左右变得明显。三分之二的欧洲儿童和青少年不够活跃。我们的研究结果表明,身体活动在性别、国家和地区方面存在显着差异。这些结果应鼓励政策制定者、政府、
