Walking school buses (WSB) increased children's physical activity, but impact on pedestrian safety behaviors (PSB) is unknown. We tested the feasibility of a protocol evaluating changes to PSB during a WSB program. Outcomes were school-level street crossing PSB prior to (Time 1) and during weeks 4-5 (Time 2) of the WSB. The protocol collected 1252 observations at Time 1 and 2548 at Time 2. Mixed model analyses yielded: intervention schoolchildren had 5-fold higher odds (p<0.01) of crossing at the corner/crosswalk but 5-fold lower odds (p<0.01) of stopping at the curb. The protocol appears feasible for documenting changes to school-level PSB.
步行校车(WSB)增加了儿童的身体活动量,但对行人安全行为(PSB)的影响尚不清楚。我们测试了一种方案的可行性,该方案旨在评估 WSB 项目期间 PSB 的变化。结果是 WSB 前(时间 1)和第 4-5 周(时间 2)的学校级过街 PSB。该方案在时间 1 收集了 1252 次观察结果,在时间 2 收集了 2548 次观察结果。混合模型分析得出:参与干预的学童在街角/人行道过马路的可能性增加了 5 倍(p<0.01),但在路边停车的可能性降低了 5 倍(p<0.01)。该方案似乎可行,可以记录学校级 PSB 的变化。
