Motor vehicle crashes are a leading cause of death among children. Age- and size-appropriate restraint use is an effective way to prevent motor vehicle-related injuries and deaths. However, children are not always properly restrained while riding in a motor vehicle, and some are not restrained at all, which increases their risk for injury and death in a crash.

The Crash Outcome Data Evaluation System (CODES) is a multistate program facilitated by the National Highway Traffic Safety Administration to probabilistically link police crash reports and hospital databases for traffic safety analyses. Eleven participating states (Connecticut, Georgia, Kentucky, Maryland, Minnesota, Missouri, Nebraska, New York, Ohio, South Carolina, and Utah) submitted data to CODES during the reporting period. Descriptive analysis was used to describe drivers and child passengers involved in motor vehicle crashes and to summarize crash and medical outcomes. Odds ratios and 95% confidence intervals were used to compare a child passenger's likelihood of sustaining specific types of injuries by restraint status (optimal, suboptimal, or unrestrained) and seating location (front or back seat). Because of data constraints, optimal restraint use was defined as a car seat or booster seat use for children aged 1-7 years and seat belt use for children aged 8-12 years. Suboptimal restraint use was defined as seat belt use for children aged 1-7 years. Unrestrained was defined as no use of car seat, booster seat, or seat belt for children aged 1-12 years.
Optimal restraint use in the back seat declined with child's age (1 year: 95.9%, 5 years: 95.4%, 7 years: 94.7%, 8 years: 77.4%, 10 years: 67.5%, 12 years: 54.7%). Child restraint use was associated with driver restraint use; 41.3% of children riding with unrestrained drivers also were unrestrained compared with 2.2% of children riding with restrained drivers. Child restraint use also was associated with impaired driving due to alcohol or drug use; 16.4% children riding with drivers suspected of alcohol or drug use were unrestrained compared with 2.9% of children riding with drivers not suspected of such use. Optimally restrained and suboptimally restrained children were less likely to sustain a traumatic brain injury than unrestrained children. The 90th percentile hospital charges for children aged 4-7 years who were in motor vehicle crashes were $1,630.00 and $1,958.00 for those optimally restrained in a back seat and front seat, respectively; $2,035.91 and $3,696.00 for those suboptimally restrained in a back seat and front seat, respectively; and $9,956.60 and $11,143.85 for those unrestrained in a back seat and front seat, respectively.
Proper car seat, booster seat, and seat belt use among children in the back seat prevents injuries and deaths, as well as averts hospital charges. However, the number, severity, and cost of injuries among children in crashes who were not optimally restrained or who were seated in a front seat indicates the need for improvements in proper use of age- and size-appropriate car seats, booster seats, and seat belts in the back seat.
Effective interventions for increasing proper child restraint use could be universally implemented by states and communities to prevent motor vehicle-related injuries among children and their resulting costs.
机动车事故是儿童死亡的主要原因之一。使用符合年龄和体型的约束装置是预防与机动车相关的伤害和死亡的有效方法。然而,儿童在乘坐机动车时并非总是得到适当的约束,有些儿童甚至完全没有约束,这增加了他们在事故中受伤和死亡的风险。
2005-2008 年。
碰撞后果数据评估系统(CODES)是由美国国家公路交通安全管理局促成的一个多州项目,旨在通过概率链接警察碰撞报告和医院数据库进行交通安全分析。在报告期内,11 个参与州(康涅狄格州、佐治亚州、肯塔基州、马里兰州、明尼苏达州、密苏里州、内布拉斯加州、纽约州、俄亥俄州、南卡罗来纳州和犹他州)向 CODES 提交了数据。描述性分析用于描述涉及机动车碰撞的驾驶员和儿童乘客,并总结碰撞和医疗结果。比值比和 95%置信区间用于比较儿童乘客根据约束状态(最佳、次佳或未约束)和座位位置(前座或后座)发生特定类型伤害的可能性。由于数据限制,最佳约束使用被定义为 1-7 岁儿童使用汽车座椅或增高座椅,8-12 岁儿童使用安全带。次佳约束使用被定义为 1-7 岁儿童使用安全带。未约束被定义为 1-12 岁儿童未使用汽车座椅、增高座椅或安全带。
后座中最佳约束使用随儿童年龄的增长而下降(1 岁:95.9%,5 岁:95.4%,7 岁:94.7%,8 岁:77.4%,10 岁:67.5%,12 岁:54.7%)。儿童约束装置的使用与驾驶员的约束装置使用相关;与乘坐有约束驾驶员的儿童相比,41.3%的儿童与未约束的驾驶员一起乘车,而 2.2%的儿童与有约束的驾驶员一起乘车。儿童约束装置的使用也与因酒精或药物使用而导致的驾驶能力受损有关;与未怀疑有酒精或药物使用的驾驶员一起乘车的儿童中,16.4%的儿童未约束,而与未怀疑有此类使用的驾驶员一起乘车的儿童中,有 2.9%的儿童未约束。与未约束的儿童相比,最佳约束和次佳约束的儿童发生创伤性脑损伤的可能性较低。4-7 岁儿童因机动车碰撞而住院的 90 百分位医院费用分别为:最佳约束在后排座椅和前排座椅的费用分别为 1630.00 美元和 1958.00 美元;次佳约束在后排座椅和前排座椅的费用分别为 2035.91 美元和 3696.00 美元;未约束在后排座椅和前排座椅的费用分别为 9956.60 美元和 11143.85 美元。
儿童在后座中正确使用汽车座椅、增高座椅和安全带可预防伤害和死亡,并避免医疗费用。然而,在未最佳约束或坐在前座的儿童中发生的伤害的数量、严重程度和成本表明,需要改进在后座中正确使用适合年龄和体型的汽车座椅、增高座椅和安全带。
各州和社区可以普遍实施有效的干预措施,以增加儿童约束装置的正确使用,从而预防儿童与机动车相关的伤害及其造成的费用。
