为了确定安全带使用对妊娠结局的影响，我们对涉及机动车碰撞的孕妇（妊娠20周或以上）进行了一项基于人群的回顾性队列研究。从1980年到1988年，在警方调查的机动车事故中，有1243名有安全带的孕妇和1349名没有安全带的孕妇获得了出生和胎儿死亡证明。在调整车祸发生时的年龄和胎龄后，未系安全带的孕妇驾驶员低出生体重儿的可能性是系安全带孕妇驾驶员的1.9倍（95%可信区间= 1.2,2.9），在车祸发生后48小时内分娩的可能性是系安全带孕妇驾驶员的2.3倍（95%可信区间= 1.1,4.8）。虽然在未约束的妇女中观察到胎儿死亡风险增加的趋势，但发生的胎儿死亡太少，无法准确描述与约束状态的任何关联。这项研究提供了保证，目前关于孕妇使用安全带的建议是适当的，应该继续下去。
To determine the effect of seatbelt use on pregnancy outcome we conducted a population-based retrospective cohort study of pregnant women (20 weeks' gestation or more) involved in motor vehicle collisions. Birth and fetal death certificates were obtained for 1243 restrained and 1349 unrestrained pregnant women involved in police-investigated motor vehicle crashes from 1980 through 1988. Unrestrained pregnant women drivers were 1.9 times more likely to have a low birth weight baby (95% confidence intervals = 1.2, 2.9) and 2.3 times more likely to give birth within 48 hours after the motor vehicle crash (95% confidence intervals = 1.1, 4.8) than restrained pregnant women drivers after adjusting for age and gestational age at crash. Although a trend for an increased risk of fetal deaths was observed among unrestrained women, too few fetal deaths occurred to accurately describe any association with restraint status. This study provides reassurance that the current recommendations on use of seatbelts by pregnant women are appropriate and should be continued.
