Abstract

OBJECTIVE

To estimate the association of rear seat safety belt use with death in a traffic crash.

DESIGN

Matched cohort study.

SETTING

The US during 2000 through 2004.

SUBJECTS

Drivers (10,427) and rear seat passengers (15,922) in passenger vehicles that crashed and had at least one driver or rear passenger death. Data from the Fatality Analysis Reporting System.

MAIN OUTCOME MEASURES

The adjusted relative risk (aRR) of death for a belted rear seat passenger compared with an otherwise similar unbelted rear passenger.

RESULTS

Safety belt use was associated with a reduced risk of death for rear car occupants: outboard rear seat aRR 0.42 (95% CI 0.38 to 0.46), and center rear seat aRR 0.30 (95% CI 0.20 to 0.44). For rear occupants of light trucks, vans, and utility vehicles, the estimates were: outboard aRR 0.25 (95% CI 0.21 to 0.29), center aRR 0.34 (95% CI 0.24 to 0.48).

CONCLUSIONS

If the authors' estimates are causal, traffic crash mortality can be reduced for rear occupants by approximately 55-75% if they use safety belts.

摘要

目的

评估交通事故中后排座位安全带使用与死亡之间的关联。

设计

匹配队列研究。

背景

2000年至2004年期间的美国。

研究对象

发生车祸且至少有一名驾驶员或后排乘客死亡的乘用车中的驾驶员(10427名)和后排乘客(15922名)。数据来自死亡分析报告系统。

主要观察指标

系安全带的后排乘客与其他情况类似的未系安全带后排乘客相比的调整后相对死亡风险(aRR)。

结果

安全带的使用与降低汽车后排乘客的死亡风险相关:外侧后排座位aRR为0.42(95%可信区间为0.38至0.46),中间后排座位aRR为0.30(95%可信区间为0.20至0.44)。对于轻型卡车、厢式货车和多功能车的后排乘客,估计值为:外侧aRR为0.25(95%可信区间为0.21至0.29),中间aRR为0.34(95%可信区间为0.24至0.48)。

结论

如果作者的估计具有因果关系,后排乘客使用安全带可使交通事故死亡率降低约55%-75%。
