Abstract

OBJECTIVE To assess the influencing factors and intermediary effects of road traffic injuries, and to provide a basis for conducting intervention projects.

METHODS Children's high-risk behaviors are not only an important mediating variable that affects the occurrence of injuries, but also affect the occurrence of injuries through interaction with the environment. Corresponding targeted interventions are required to reduce the incidence of children's walking injuries.

RESULTS Among the influencing factors of children's road traffic injuries, the higher the cognitive ability, the lower the occurrence of road injuries. The direct effect value was -0.14 ( t =-4.67, P <0.05), and the mediating effect value through behavior was -0.05 ( t = -2.50, P <0.05), the total effect is -0.19. The higher the behavioral risk, the higher the incidence of injury, with an effect value of 0.66 ( t = 7.33, P <0.05). The higher the environmental risk, the higher the incidence of injury, with an effect value of 0.16 ( t = 5.33, P <0.05). The environment can reduce the influence of cognition on the occurrence of injury, and its effect value is -0.53 ( t = -5.30, P <0.05).

CONCLUSION Children's high-risk behaviors are not only an important mediating variable that affects injury occurrence, but also affect the injury occurrence through interaction with the environment. Corresponding targeted interventions are needed to reduce the occurrence of children's walking injury.

摘要:目的 评估道路交通伤害的影响因素及中介效应，为开展干预项目提供依据。方法 儿童的高危行为不仅是影响伤害发生的一个重要中介变量，而且通过与环境的交互作用影响伤害发生，需采取相应的针对性干预措施以减少儿童步行伤害的发生。结果 在儿童道路交通伤害的影响因素中，认知能力越高，道路伤害发生越低，直接效应值为-0.14（t＝-4.67，P＜0.05），通过行为的中介效应值为-0.05（t＝-2.50，P＜0.05），总效应为-0.19。行为危险度越高，伤害发生率越高，其效应值为0.66（t＝7.33，P＜0.05）。环境危险度越高，伤害发生率越高，其效应值为0.16 （t＝5.33，P＜0.05）。环境能减弱认知对伤害发生的影响，其效应值为-0.53（t＝-5.30，P＜0.05）。结论 儿童的高危行为不仅是影响伤害发生的一个重要中介变量，而且通过与环境的交互作用影响伤害发生，需采取相应的针对性干预措施以减少儿童步行伤害的发生。
