Objective measurement of daily steps was used to assess whether children (n = 2,076) in Years 1, 5 and 10 who reported walking to or from school were more active and more likely to reach recommended step targets than those who were driven or took public transport to school. Walking to school was associated with higher school-day steps in older children (16,238 vs 15,275 for Year 5 male p < .05, 13,521 vs 12,502 for Year 5 female p < .01, 12,109 vs 11,373 for Year 10 female p < .05). The proportion of children who met recommended step thresholds was higher in those who walked to school compared with those who took motorized transport, and this was significant for Year 5 females (71.7% vs 54.5%, p < .01). This study suggests that walking to school for older children has potential to contribute significantly to daily activity levels and increases the likelihood of attaining recommended step targets. These data should encourage public policy and those concerned with the built environment to provide and support opportunities for walking to school.
通过客观测量每日步数来评估一年级、五年级和十年级报告步行上下学的儿童（n = 2076）是否比那些乘车或乘坐公共交通上学的儿童更活跃，更有可能达到推荐的步数目标。步行上学与年龄较大儿童在上学日的步数较多有关（五年级男性：16238步对15275步，p <.05；五年级女性：13521步对12502步，p <.01；十年级女性：12109步对11373步，p <.05）。与乘坐机动交通工具上学的儿童相比，步行上学的儿童达到推荐步数阈值的比例更高，这在五年级女性中具有显著性（71.7%对54.5%，p <.01）。这项研究表明，年龄较大的儿童步行上学有可能显著提高日常活动水平，并增加达到推荐步数目标的可能性。这些数据应促使公共政策制定者以及关注建成环境的人士提供并支持步行上学的机会。
