Abstract

This paper presents a study using 1997-2015 National Automotive Sampling System (NASS) Crashworthiness Data System (CDS) data to estimate the risk and body region distribution of injury for rear-seated children aged 4-18 using vehicle seat belts in frontal crashes and evaluate specific cut-off points for age as effect modifiers of the association between use of vehicle seat belts and their respectively significant injury. Logistic regression analyses were conducted to evaluate the factors affecting the injury risk for children aged 4-18. Results showed that seatbelt was the most common form of restraint for children older than four years of age seated in the rear seat. Children 8-12 years of age were at the highest risk of significant injury among children 4-18 years old. The risks of significant injury by body regions varied among children 4-18 years old due to the differences in anthropometry. Children 4-8 years of age appeared to be at increased risk of injury from using seat belts, whereas children 9-18 years of age experienced protective effects of using seat belts.

年龄对正面碰撞中后排儿童乘员损伤模式的影响

本文利用1997-2015年美国国家汽车抽样系统(NASS)抗撞性数据系统(CDS)的数据，估算了4-18岁儿童在正面碰撞中使用安全带后坐的伤害风险和身体区域分布，并评估了年龄的特定截止点作为汽车安全带使用与各自重大伤害之间关联的影响调节器。采用Logistic回归分析评价4 ~ 18岁儿童伤害风险的影响因素。结果表明，安全带是四岁以上儿童坐在后座上最常见的约束形式。在4-18岁的儿童中，8-12岁的儿童遭受重大伤害的风险最高。由于人体测量学的差异，4-18岁儿童的身体区域严重损伤的风险有所不同。4-8岁的儿童似乎因使用安全带而受伤的风险增加，而9-18岁的儿童则经历了使用安全带的保护作用。

期刊介绍： The IJVS aims to provide a refereed and authoritative source of information in the field of vehicle safety design, research, and development. It serves applied scientists, engineers, policy makers and safety advocates with a platform to develop, promote, and coordinate the science, technology and practice of vehicle safety. IJVS also seeks to establish channels of communication between industry and academy, industry and government in the field of vehicle safety. IJVS is published quarterly. It covers the subjects of passive and active safety in road traffic as well as traffic related public health issues, from impact biomechanics to vehicle crashworthiness, and from crash avoidance to intelligent highway systems.
