中学生自行车伤害影响因素病例对照研究

Risk factors of bicycle traffic injury among middle school students in Yangpu district,Shanghai:a case-control study

目的探讨中学生自行车伤害的影响因素,为中学生自行车伤害预防控制及干预措施的制定提供科学依据。方法在对上海市杨浦区中学生进行自行车伤害流行病学调查的基础上,采用1∶3匹配的病例对照研究方法 ,对筛选出的294例伤害病例进行相关因素的单因素和多因素条件Logistic回归分析。结果在雨/雪/大风等恶劣气候条件下骑车（OR=2.66,95%CI=1.931~3.654）、担心骑车总会出事（OR=1.59,95%CI=1.190~2.128）、戴耳机听音乐骑车（OR=1.45,95%CI=1.057~2.000）、与他人扶身并行互相追逐（OR=1.42,95%CI=1.011~1.981）为中学生自行车伤害发生的危险因素,16~20岁年龄段（OR=0.57,95%CI=0.424~0.762）为保护因素。结论不良的骑车行为是中学生自行车伤害的主要危险因素。

Objective To explore risk factors of bicycle traffic injury among middle school students and to provide guide for control and prevention of bicycle traffic injury.Methods A 1∶3 indvidual matching case-control study was conducted among 294 bicycle traffic injuries and 882 healthy controls from middle school students in Yangpu district,Shanghai city.Univariate and multivariate logistic regression analysis were performed.Results Riding bicycle in bad weather condition,listening to music,chasing each other,and worrying about the accident significantly increased the risk of bicycle traffic injury with the odds ratios of 2.66,1.59,1.45,and 1.42,respectively.The age was shown to be a protective factor with an odds ratio of 0.57.Conclusion Riding bicycle in bad weather condition,listening to music,chasing each other,and worrying about the accident were major risk factors of bicycle injury among middle school students.
