Objective

To analyze the influence of active commuting to and from school on daily physical activity of children (7–9 years old) and adolescents (10–12 years old). Methods: Longitudinal study, including students from a public school (n = 462; 7–12 years old; 53.6% boys, 46.4% girls). Active commuting (walking and cycling) and physical activities were self-reported using a computational questionnaire. The analyses were conducted via modeling with generalized estimation equations, adjusted for sex, age, and BMI z-score. Results: Active commuting (walking, cycling) occurred in 27.4% and 10.1% of the sample, respectively. Students who cycled to and from school showed 20% more daily physical activity (β² = 1.20; 95% CI = 1.03–1.40), compared to those who used passive transport. The analysis of the interaction between age and active commuting cycling showed that children who cycled to and from school exhibited more daily physical activity than those in the same age group who did not cycle and those in the adolescent's group who cycled or did not cycle to/from school. Conclusion: Cycling as a way of commuting to and from school was associated with greater daily physical activity. Among children, cycling helped to maintain stable daily physical activity and higher than that observed among children and adolescents who used passive transport. There was no difference in daily physical activity between adolescents that cycled or no to/from school.

上下班对儿童和青少年日常体育活动的影响

客观的

分析主动上下学对儿童（7-9岁）和青少年（10-12岁）日常身体活动的影响。方法：纵向研究，包括来自公立学校的学生（n = 462； 7-12岁；男生53.6％，女生46.4％）。主动通勤（步行和骑自行车）和身体活动使用计算机调查表进行自我报告。该分析是通过使用广义估计方程建模进行的，并针对性别，年龄和BMI z得分进行了调整。结果：主动通勤（步行，骑自行车）分别占样本的27.4％和10.1％。谁循环往返于学校学生表现出20％以上的日常体力活动（β ² = 1.20; 与那些使用被动运输的人相比，95％CI = 1.03-1.40）。对年龄与主动通勤自行车之间的相互作用进行的分析表明，骑自行车上下学的孩子比没有骑自行车的同龄组和骑自行车或不骑自行车去/青少年组的儿童每天的体育活动更多。从学校。结论：骑自行车作为往返学校的一种方式，与每天进行更多的体育锻炼有关。在儿童中，骑自行车有助于维持稳定的日常体育活动，并且比使用被动运输的儿童和青少年所观察到的要高。骑自行车或不上学的青少年之间的日常体育活动没有差异。
