To investigate if students who use of Active Transportation (AT) to and from school among urban and rural Canadian children are more likely to meet physical activity recommendations.
The Raising healthy Eating and Active Living in Alberta (REAL Kids Alberta) study is a population-based health survey among Grade 5 students. In 2009, physical activity levels were measured using time-stamped pedometers (number of steps/hour) among 688 children. Parents reported mode of transportation to and from school (AT/non-AT). Multilevel multiple linear regression analyses with corresponding β coefficients were conducted to quantify the relationship between mode of transportation to and from school with (1) overall step count, and (2) the likelihood of achieving at least 13,500 steps per day recommended for optimal growth and development.
Among urban children, those who used AT to and from school accumulated more steps [β=1124(95% CI=170,2077)] and although not significant, were more likely to achieve the recommended 13,500 steps/day compared to those not using AT to and from school [OR=1.61(95% CI=0.93,2.81)].
Using AT to and from school appears to be beneficial to children by supplementing their physical activity, particularly those living in urban regions. Strategies to promote physical activity are needed, particular for children residing in rural regions and smaller towns.
调查加拿大城乡儿童中，使用主动交通（AT）上下学的学生是否更有可能达到身体活动建议。
在 2009 年，“阿尔伯塔省培养健康饮食和积极生活方式（REAL Kids Alberta）”研究对五年级学生进行了基于人群的健康调查。使用带时间戳的计步器（每小时步数）测量了 688 名儿童的身体活动水平。家长报告了上下学的交通方式（AT/非 AT）。采用多层次多元线性回归分析，计算相应的β系数，量化了上下学交通方式与（1）总步数，和（2）达到每天推荐的 13500 步以促进最佳生长和发育的可能性之间的关系。
在城市儿童中，使用 AT 上下学的儿童累计的步数更多[β=1124（95%CI=170，2077）]，尽管不显著，但与不使用 AT 上下学的儿童相比，更有可能达到每天推荐的 13500 步[OR=1.61（95%CI=0.93，2.81）]。
使用 AT 上下学似乎对儿童有益，可补充他们的身体活动，尤其是居住在城市地区的儿童。需要采取促进身体活动的策略，特别是针对居住在农村地区和小镇的儿童。
