Physical activity (PA) is recognized as a marker of health. The aim was to investigate PA differences from adolescence to young adulthood. European adolescents included in the HELENA study were invited to participate in a follow-up study, 10 years later. The present study included 141 adults (25.0 ± 1.4 years) for whom valid accelerometer data were available in adolescence and adulthood. Changes in PA by sex, weight and maternal education level were explored with interactions. Time spent in sedentary activity, light PA (LPA) and moderate PA (MPA) increased by 39.1, 59.6 and 6.6 min/day, respectively, whereas the time spent in vigorous PA (VPA) decreased by 11.3 min/day compared with adolescent VPA (p < 0.05). Increases in MPA were greater on weekends compared with weekdays, but we found a greater decrease in VPA on weekdays compared with weekends. Moderate-to-vigorous PA (MVPA) decreased significantly on weekdays (-9.6 min/day; 95%CI, -15.9 to -3.4), while it increased on weekends (8.4 min/day; 95%CI, 1.9 to 14.8). Significant heterogeneity was found across sexes for VPA and MVPA, with a stronger decrease in VPA in males compared with females and a significant decrease in MVPA (-12.5 min/day; 95%CI, -20.4 to -4.5) in males but not in females (1.9 min/day; 95%CI, -5.5 to 9.2). No significant heterogeneity was found to be linked to maternal education level or weight, irrespective of PA level. Conclusion: Our data suggest that the transition from adolescence to young adulthood is a critical period for lifestyle PA habits. A decline in VPA and an increasingly sedentary time were observed. The observed changes are worrying and may increase the risk of developing adverse health consequences later in life. What is Known: • The transition from adolescence to adulthood is marked by many life changes affecting lifestyle habits. Most studies tracking physical activity from adolescence to adulthood were done using PA questionnaires, which is a subjective method. What is New: • Our study bring first data on objective changes in PA patterns between adolescence and young adulthood, taking account of BMI, sex and maternal educational level. Our results suggest that the transition from adolescence to young adulthood is a critical period for lifestyle PA habits, especially for time spent on sedentary activities.
身体活动（PA）被认为是健康的标志。本研究旨在探讨从青少年到成年早期的 PA 差异。参加 HELENA 研究的欧洲青少年受邀参加了一项后续研究，10 年后。本研究纳入了 141 名成年人（25.0±1.4 岁），他们在青少年和成年期都有有效的加速度计数据。通过交互作用探讨了性别、体重和母亲教育水平对 PA 的影响。与青少年时的 VPA 相比，久坐时间、低强度 PA（LPA）和中强度 PA（MPA）分别增加了 39.1、59.6 和 6.6 分钟/天，而高强度 PA（VPA）则减少了 11.3 分钟/天（p<0.05）。与工作日相比，周末的 MPA 增加幅度更大，但与周末相比，工作日的 VPA 减少幅度更大。与工作日相比，周末时中高强度 PA（MVPA）增加了 9.6 分钟/天（95%CI，1.9 至 17.3），而工作日时则减少了 9.6 分钟/天（95%CI，-15.9 至-3.4）。VPA 和 MVPA 在性别上存在显著异质性，男性的 VPA 下降幅度明显大于女性，男性的 MVPA 下降幅度也较大（-12.5 分钟/天；95%CI，-20.4 至-4.5），而女性则没有（1.9 分钟/天；95%CI，-5.5 至 9.2）。无论 PA 水平如何，母亲教育水平或体重与 MVPA 无显著异质性。结论：我们的数据表明，从青少年到成年早期的过渡是生活方式 PA 习惯的关键时期。观察到 VPA 下降和久坐时间增加。观察到的变化令人担忧，可能会增加以后生活中出现不良健康后果的风险。已知：• 从青少年到成年的过渡伴随着许多影响生活方式习惯的生活变化。大多数从青少年到成年追踪 PA 的研究都是使用 PA 问卷进行的，这是一种主观的方法。新发现：• 我们的研究首次提供了青少年和成年早期之间 PA 模式客观变化的数据，考虑了 BMI、性别和母亲教育水平。我们的研究结果表明，从青少年到成年早期的过渡是生活方式 PA 习惯的关键时期，特别是对久坐时间的影响。
