Background Cycling has the potential to encourage physical activity as well as advancing societal goals such as reducing carbon emissions; encouraging cycling is therefore a policy goal in many contexts. We analysed individual level data from the whole of England on factors associated with cycling among adolescents, including cycle training delivered by the age of 11 years in primary schools. Methods Data came from the nationally representative Millennium Cohort Study collected when participants were aged 13-15 years (adolescents). We assessed frequency of cycling at least once per week (regular cycling) and used logistic regression to assess how this differed across characteristics including demographic, health and environmental factors, as well as receiving cycle training ('Bikeability') in primary school. Results We found that 21.0% of adolescents cycled at least once per week. In fully adjusted analyses, this was more common among boys than girls (32.5% vs. 9.4%, p < 0.001), and those in rural areas than urban areas (24.9% vs. 20.3%, p < 0.001). Adolescents in areas with higher prevalence of adult cycle commuting were more likely to cycle regularly (26.1% in high cycling areas vs. 19.3% in low cycling areas, p < 0.001). Participants offered cycle training in primary school were not more likely to cycle regularly as adolescents (21.7% vs. 22.3%, p = 0.528). Discussion Approximately one in five adolescents in England cycles regularly, although being offered cycle training in primary school was not linked to greater cycling. Many of the factors associated with adolescent cycling are similar to those for adults and adolescents are more likely to cycle in areas with higher levels of adult cycling.

英格兰青少年的自行车训练和与自行车运动相关的因素。

背景 骑自行车有可能鼓励身体活动以及推进减少碳排放等社会目标；因此，在许多情况下，鼓励骑自行车是一项政策目标。我们分析了整个英格兰关于青少年骑自行车相关因素的个人水平数据，包括小学 11 岁时提供的自行车训练。方法 数据来自在参与者 13-15 岁（青少年）时收集的具有全国代表性的千年队列研究。我们评估了每周至少一次骑自行车的频率（定期骑自行车），并使用逻辑回归来评估这在包括人口、健康和环境因素在内的特征以及在小学接受自行车训练（“骑自行车能力”）之间有何不同。结果 我们发现 21。0% 的青少年每周至少骑自行车一次。在完全调整的分析中，这在男孩中比女孩更常见（32.5% 对 9.4%，p < 0.001），农村地区比城市地区更常见（24.9% 对 20.3%，p < 0.001）。成人自行车通勤率较高地区的青少年更有可能定期骑自行车（高自行车地区为 26.1%，而低自行车地区为 19.3%，p < 0.001）。在小学提供自行车训练的参与者在青少年时期不太可能定期骑自行车（21.7% 对 22.3%，p = 0.528）。讨论英格兰大约五分之一的青少年定期骑自行车，尽管在小学接受自行车训练与更多的自行车运动无关。
