To evaluate the California Child Passenger Restraint Law requiring children under four years of age to be transported in car seats, we examined monthly injury and fatality levels from January 1978 to December 1983 for children 0-3 and 4-7 years of age using Box-Jenkins time series models. A significant 8.36 per cent reduction in injuries was found for the 0-3 year old age group, but no significant reduction in injuries was found for 4-7 year olds. No significant reduction in fatalities was found for either age group. A similar analysis of injuries and fatalities in Texas, a state without a car seat law, showed no significant reductions in either injuries or fatalities. There was no change in the number of California 0-3 year olds in the years after the law was enacted.
为评估加利福尼亚州儿童乘客约束法（该法律要求四岁以下儿童乘车时须使用儿童安全座椅），我们运用博克斯-詹金斯时间序列模型，研究了1978年1月至1983年12月期间0至3岁和4至7岁儿童的月度受伤及死亡情况。结果发现，0至3岁年龄组的受伤率显著降低了8.36%，但4至7岁儿童的受伤率并未显著降低。两个年龄组的死亡率均未显著降低。对没有儿童安全座椅法律的得克萨斯州的受伤及死亡情况进行的类似分析表明，该州的受伤率和死亡率均未显著降低。在该法律颁布后的几年里，加利福尼亚州0至3岁儿童的数量没有变化。
