We directly observed the prevalence of walking and bicycling (active commuting) to 8 randomly selected urban and suburban elementary schools. When school was used as the unit of analysis, only 5.0% of the students actively commuted to or from school across all observed trips. Active commuting was not affected (P >/=; 18) by school urbanization level, school socioeconomic status, time of day, day of week, weather conditions, or temperature. These results indicate a need for school- and community-based interventions.
我们直接观察了8所随机选取的城市和郊区小学学生步行和骑自行车(主动通勤)的比例。以学校为分析单位时,在所有观察到的行程中,只有5.0%的学生主动往返学校。主动通勤不受学校城市化水平、学校社会经济地位、一天中的时间、一周中的日期、天气状况或温度的影响(P≥0.18)。这些结果表明需要开展以学校和社区为基础的干预措施。
