有一个广泛持有和有影响力的观点认为，身体活动在青春期开始下降。这项研究旨在确定儿童和青少年时期身体活动变化的时间。纵向队列研究（Gateshead Millennium研究），随访8年，来自英格兰东北部。队列成员包括在7岁，9岁，12岁和15岁时研究的社会经济代表性样本; 545人提供了两个或更多时间点的体力活动数据。在4个时间点，使用Actigraph加速度计在5-7天内客观量化习惯性体力活动总量和中等至剧烈强度体力活动（MVPA）。线性混合模型确定了8年期间身体活动变化的时间，轨迹分析用于确定具有不同年龄相关变化模式的亚组。确定了四种身体活动总量变化的轨迹，代表所有参与者的100%：所有轨迹从7岁开始下降。没有证据表明身体活动的减少是从青春期开始的，也没有证据表明青春期身体活动的减少比儿童期大得多，或者女孩比男孩大。一组（19%的男孩）有相对较高的MVPA，在7至15岁之间保持稳定。未来促进体育活动的政策和研究工作应在青春期之前开始，并应包括男孩和女孩。
There is a widely held and influential view that physical activity begins to decline at adolescence. This study aimed to identify the timing of changes in physical activity during childhood and adolescence. Longitudinal cohort study (Gateshead Millennium Study) with 8 years of follow-up, from North-East England. Cohort members comprise a socioeconomically representative sample studied at ages 7, 9, 12 and 15 years; 545 individuals provided physical activity data at two or more time points. Habitual total volume of physical activity and moderate-to-vigorous intensity physical activity (MVPA) were quantified objectively using the Actigraph accelerometer over 5–7 days at the four time points. Linear mixed models identified the timing of changes in physical activity across the 8-year period, and trajectory analysis was used to identify subgroups with distinct patterns of age-related changes. Four trajectories of change in total volume of physical activity were identified representing 100% of all participants: all trajectories declined from age 7 years. There was no evidence that physical activity decline began at adolescence, or that adolescent declines in physical activity were substantially greater than the declines during childhood, or greater in girls than boys. One group (19% of boys) had relatively high MVPA which remained stable between ages 7 and15 years. Future policy and research efforts to promote physical activity should begin well before adolescence, and should include both boys and girls.
