We performed a population-based study of bicycle-related brain injuries in San Diego, California, residents during 1981. Incidence rates among males were three times higher than for females and were highest at ages 10-14 years for males. Only one-third of bicycle-related brain injuries involved collision with a motor vehicle, and this proportion was independent of age or gender. Brain injuries from motor-vehicle collisions were more severe than those resulting from other causes. Over half the brain-injured bicyclists aged 15 and older who were blood alcohol tested were legally intoxicated.
1981年,我们对加利福尼亚州圣地亚哥居民中与自行车相关的脑损伤进行了一项基于人群的研究。男性的发病率是女性的三倍,且在10 - 14岁男性中最高。与自行车相关的脑损伤中,只有三分之一涉及与机动车碰撞,这一比例与年龄或性别无关。机动车碰撞导致的脑损伤比其他原因导致的更严重。在接受血液酒精检测的15岁及以上脑损伤自行车骑行者中,超过一半的人处于法定醉酒状态。
