中学生道路交通伤害影响因素及主要行为因素间的交互作用

Influencing factors and interaction between main behavioral factors of road traffic injuries among middle school students

目的了解绍兴市中学生道路交通伤害(road traffic injuries,RTIs)报告情况,分析发生RTIs的影响因素及其交互作用,为RTIs的防控提供基础依据。方法采用多阶段分层整群抽样方法,从绍兴市171个初中及高中班级抽取7200名学生。采用logistic回归分析模型及交互作用模型分析中学生RTIs的危险因素和主要行为因素间的交互作用。结果绍兴市中学生近1年的RTIs报告率为15.44%。男生、高中生、步行/骑自行车上下学和上下学途中步行所需时间≥20 min是中学生发生RTIs的危险因素。行为因素中,上下学途中使用电子设备、上下学途中在马路上玩耍时间≥20 min、上学快要迟到但遇红灯时跟着别人穿行路口分别是不使用电子设备、从不在马路上玩耍、等信号灯转绿后再穿行者发生RTIs风险的1.54倍(95%CI:1.31~1.81,P<0.001)、2.37倍(95%CI:1.39~4.05,P<0.001)和2.84倍(95%CI:1.62~5.00,P<0.001)。上下学途中使用电子设备和在马路上玩耍共存时,发生RTIs的风险是两者都不的3.91倍(95%CI:2.95~5.18),且存在相加交互作用(P<0.05)。结论中学生RTIs报告率较高,道路危险行为是其重要可改变影响因素,且上下学途中使用电子设备和在马路上玩耍对RTIs的发生具有相加作用,应重点关注。

Objective To investigate the incidence and influencing factors for road traffic injuries(RTIs)among middle and high school students in Shaoxing,so as to provide a basis for the prevention of RTIs.Methods A total of 7200 students were selected from 171 junior and senior high school classes in Shaoxing using a multi-stage stratified cluster sampling method.Logistic regression model and interaction model were used to analyze the interaction between risk factors and main behavioral factors of RTIs.Results The 1-year incidence of RTIs in middle and high school students was 15.44%.Males,high school students,walking/cycling to and from school,and walking time≥20 min on the way to and from school were risk factors for RTIs in middle school students.With regard to behavioral factors,our study showed that using electronic devices(OR=1.54,95%CI:1.31-1.81,P<0.001),playing on the road≥20 min(OR=2.37,95%CI:1.39-4.05,P<0.001),and running the red light(OR=2.84,95%CI:1.62-5.00,P<0.001)were associated with an increased risk of RTIs.Moreover,using electronic devices and playing on the road showed an additive interaction,with an OR of 3.91(95%CI:2.95-5.18,P<0.05).Conclusions Higher rates of RTIs were reported among middle school students,with road risk behaviors being a significant modifiable influence.The use of electronic devices on the way to and from school and playing on the road have an additive effect on the occurrence of RTIs and should be highlighted.
