中小学生交通伤害影响因素分析

Risk factors of traffic injury among students in middle and primary schools

目的探讨学生认知行为、道路环境等与道路交通伤害的关系及影响因素。方法采用多阶段分层整群抽样方法,抽取深圳市6个区的27175名中小学生进行问卷调查,对可能危险因素进行Logistic回归分析。结果交通伤害发生率为5.2%,男生高于女生(χ2=56.000,P=0.000)。10～14岁的儿童步行者交通伤害发生率最高,为6.4%。路上打闹行为(OR=2.123)、过路口方便感(OR=1.565)、路标判断(OR=1.558)、信号灯识别(OR=1.440)、步行路段安全感(OR=1.141)、上学途径路口数(OR=1.036)等是交通伤害发生的重要危险因素。结论道路交通伤害与学生认知行为、道路环境等因素密切相关,可针对这些危险因素采取相应措施,以降低学生交通伤害的发生。

Objective To explore the risk factors of traffic injuries among students of middle and primary schools so as to provide measures for injury control. Methods Overall 27175 students from six districts in Shenzhen were selected with multistage stratified cluster sampling. Logistic regression model was used to analyze risk factors. Results The traffic injury incidence was 5.2% with a higher incidence in boys than in girls（x^2 =56. 000,P =0. 000）. The incidence in children aged 10-14 was the highest（ 6.4% ）. Risk factors for the injuries included gambol on road（ OR =2. 123） ,convenience for crossing the road （ OR = 1. 565 ）, road sign judgment（ OR = 1. 558 ）, traffic light identification （ OR = 1. 440）, ambulation safety （ OR = 1. 141 ） ,number of crossroad on the way to school（ OR = 1.036 ）. Conclusion The occurrence of traffic injuries is influenced by a number of risk factors related to student＇s cognition, behavior and road environment. Pertinent measure should be adopted to control traffic injuries among the students.
