The decline in active commuting to and from school in the United States is, in part, due to urban design standards and public policies that promote automobile travel and discourage pedestrian activity.
The current investigation examines active commuting at neighborhood schools and how it is altered by distance to school, student age and its potential impact on Body Mass Index.
Demographic and transportation datasets were obtained for 5367 elementary students (K-5th grade) and middle school students (6th-8th grade) in 2 Midwestern communities.
4379 (81.6%) students were successfully geocoded and 21.9% actively commute to school at least half of the time meeting the Healthy People 2010 objective 22-14. Of those students who could potentially actively commute to school (0.5 mile for grades K-5 and 1 mile for grades 6-8) 36.6% are passive commuters. No significant negative associations were found between BMI z-score or BMI percentile with accumulation of activity through active commuting (frequency × distance) for elementary (r = -0.04, P = .27) or middle school students (r = .027, P = .56).
Many elementary students living within 0.3-0.4 miles are being driven to school. Promoting pedestrian-friendly communities and making healthy and sustainable transportation choices should be priorities for community leaders and school administrators.
美国往返学校的主动通勤量下降，部分原因是城市设计标准和公共政策促进了汽车出行，抑制了行人活动。
本研究调查了社区学校的主动通勤情况，以及距离学校、学生年龄如何改变这种情况，及其对体重指数的潜在影响。
从 2 个中西部社区获取了 5367 名小学生（K-5 年级）和中学生（6-8 年级）的人口统计学和交通数据集。
成功地理编码了 4379 名（81.6%）学生，其中 21.9%的学生至少有一半时间主动通勤上学，达到了《健康人民 2010 目标 22-14》。在有潜力主动上学的学生中（K-5 年级 0.5 英里，6-8 年级 1 英里），36.6%是被动通勤者。通过主动通勤（频率×距离），小学生（r = -0.04，P =.27）或中学生（r =.027，P =.56）的体重指数 z 分数或体重指数百分位数与活动量之间没有显著的负相关关系。
许多居住在 0.3-0.4 英里内的小学生都被开车送到学校。促进适合行人的社区建设，以及做出健康和可持续的交通选择，应成为社区领导人和学校管理人员的优先事项。
