Although adolescent physical activity (PA) tracks into adulthood, it is unclear if the context of PA practiced during adolescence predicts adult PA. We previously identified five adolescent PA profiles and aimed to assess associations between these profiles and levels of PA in emerging adulthood.
Using data from the first 8 years of the MATCH study, when participants were 11 to 18 years, we identified five adolescent PA profiles: "non-participants" (9% of the sample), "dropouts" (30%), "active in unorganized PA" (19%), "active in organized PA" (27%), and "active through a variety of PA" (15%). The same participants reported their PA level (IPAQ) 2.5, 3.5, 4.5, and 5.5 years later when they were emerging adults (20, 21, 22, and 23 years). The adolescent PA profiles were included in a mixed-distribution two parts model as predictors of i) the probability of reporting any PA during emerging adulthood, and ii) the PA level of emerging adults reporting PA.
Being categorized as "non-participant" or "dropout" during adolescence was associated with similar likelihoods of reporting PA and PA level during emerging adulthood. In contrast with "non-participants", those in the "active-unorganized" (OR, 95% CI: 2.8, 2.1-3.8), "active-organized" (2.4, 1.7-3.2), and "active-variety" (3.7, 3.3-5.1) were considerably more likely to report any PA during emerging adulthood. Among emerging adults who reported some PA, those with an adolescent profile of "active-unorganized", "active-organized" and "active-variety" had higher PA levels than "non-participants" (all p < 0.01).
Profiles of PA participation during adolescence represent strong predictors of PA in emerging adulthood. Promoting participation in various types of PA during adolescence is key to preventing low PA among emerging adults.
尽管青少年身体活动（PA）会持续到成年期，但尚不清楚青少年时期进行身体活动的背景是否能预测成年后的身体活动情况。我们之前确定了五种青少年身体活动模式，并旨在评估这些模式与成年早期身体活动水平之间的关联。
利用MATCH研究前8年的数据，即参与者年龄在11至18岁时的数据，我们确定了五种青少年身体活动模式：“不参与者”（占样本的9%）、“退出者”（30%）、“参与非有组织身体活动者”（19%）、“参与有组织身体活动者”（27%）以及“通过多种身体活动保持活跃者”（15%）。同样的参与者在2.5、3.5、4.5和5.5年后，即成年早期（20、21、22和23岁）时报告了他们的身体活动水平（国际体力活动问卷，IPAQ）。青少年身体活动模式被纳入一个混合分布两部分模型，作为以下方面的预测因素：i）成年早期报告任何身体活动的概率，以及ii）报告身体活动的成年早期者的身体活动水平。
在青少年时期被归类为“不参与者”或“退出者”，与成年早期报告身体活动的可能性以及身体活动水平相似。与“不参与者”相比，“参与非有组织身体活动”（比值比[OR]，95%置信区间[CI]：2.8，2.1 - 3.8）、“参与有组织身体活动”（2.4，1.7 - 3.2）和“通过多种身体活动保持活跃”（3.7，3.3 - 5.1）的人群在成年早期报告任何身体活动的可能性要高得多。在报告了一定身体活动的成年早期者中，具有青少年时期“参与非有组织身体活动”、“参与有组织身体活动”和“通过多种身体活动保持活跃”模式的人的身体活动水平高于“不参与者”（所有p < 0.01）。
青少年时期的身体活动参与模式是成年早期身体活动的有力预测因素。促进青少年参与各种类型的身体活动是预防成年早期身体活动不足的关键。
