Daily behaviours such as active commuting to school (ACS) could be a source of physical activity, contributing to the improvement of youth cardiovascular health, however, the relationship between ACS and other aspects of a youth's health, such as sleep duration and breakfast consumption, require further clarification. The aims of this study were therefore: 1) to analyse the prevalence of modes of commuting to school, sleep duration, and breakfast consumption by age groups and gender, and 2) to analyse the association between ACS, sleep duration recommendations, and breakfast consumption by age groups and gender.
This cross-sectional study included 732 school-aged students of low-middle socioeconomic status, categorised into children (10-12 yr), young adolescents (13-15 yr), and older adolescents (16-18 yr). Modes of commuting to/from school, sleep duration, and breakfast consumption were self-reported. Logistic regression models were fitted to examine the association between ACS, sleep duration and breakfast consumption, analysed according to age groups and gender.
The percentage of students meeting sleep duration and daily breakfast recommendations was lowest in older adolescents, and highest in children (6.3% versus 50.8% p < 0.001, and 62.1%, versus 76.8%, p = 0.001, respectively). Young adolescents and girls who met the sleep duration recommendations were more likely to be active commuters than their counterparts (OR = 4.25; 95% CI = 1.81 to 9.92, p = 0.001 and OR = 2.89; 95%CI = 1.01 to 8.27, p = 0.04, respectively).
Young adolescents (13-15 yr) and girls who met the sleep duration recommendations during school days displayed a positive association with ACS. There was no association between ACS and breakfast consumption for any of the age groups or gender. Children (10-12 yr) were those that best meet with the adequate sleep duration and breakfast consumption recommendations.
日常行为，如主动上学（ACS），可能是身体活动的来源，有助于改善青年心血管健康，但 ACS 与青年健康的其他方面（如睡眠时间和早餐摄入）之间的关系仍需要进一步澄清。因此，本研究的目的是：1）按年龄组和性别分析上学交通方式、睡眠时间和早餐摄入的流行率，2）按年龄组和性别分析 ACS 与睡眠时间推荐和早餐摄入之间的关联。
本横断面研究纳入了 732 名社会经济地位较低的学龄儿童，分为儿童（10-12 岁）、青少年（13-15 岁）和青少年（16-18 岁）。上学交通方式、睡眠时间和早餐摄入情况均为自我报告。使用逻辑回归模型分析 ACS、睡眠时间和早餐摄入与年龄组和性别之间的关联。
满足睡眠时间和每日早餐推荐的学生比例在青少年中最低，在儿童中最高（6.3%比 50.8%，p<0.001，62.1%比 76.8%，p=0.001）。满足睡眠时间建议的青少年和女孩比同龄人更有可能成为积极的上学交通方式（OR=4.25；95%CI=1.81 至 9.92，p=0.001 和 OR=2.89；95%CI=1.01 至 8.27，p=0.04）。
在上学日满足睡眠时间建议的青少年（13-15 岁）和女孩与 ACS 呈正相关。在任何年龄组或性别中，ACS 与早餐摄入均无关联。（10-12 岁）的儿童最符合充足睡眠时间和早餐摄入的建议。
