Using official police reports and hospital admission and emergency room medical records, 1273 persons with confirmed medically treated motorcycle injury were identified in Sacramento County, California, during 1970. Less than 39% of all injured motorcyclists were identified in this study using only official police reports. The annual incidence rate was highest for 18-year-old male drivers. In addition to age of driver, risk of injury was associated with drivers of short stature (less than 173 cm) operating an intermediate or larger size motorcycle. Risk of injury was higher for drivers with training than for those without training or those who operated their motorcycles frequently regardless of type of use. Risk of injury was not related to make of motorcycle but was related to engine size. Two-thirds of the injury-producing collisions involved a motorcycle and a second motor vehicle. Motorcycle collisions occurred most fre quently during the afternoon and early evening hours and during the summer months, but peaks in incidence of collisions occurred during weeks which included a holiday.
利用警方官方报告以及医院入院记录和急诊室医疗记录，1970年在加利福尼亚州萨克拉门托县识别出1273名经医学治疗确诊的摩托车受伤者。在本研究中，仅使用警方官方报告识别出的受伤摩托车手不到所有受伤者的39%。18岁男性驾驶员的年发病率最高。除驾驶员年龄外，受伤风险还与身材矮小（低于173厘米）且驾驶中型或更大尺寸摩托车的驾驶员有关。接受过培训的驾驶员比未接受培训或经常骑摩托车（无论使用类型如何）的驾驶员受伤风险更高。受伤风险与摩托车品牌无关，但与发动机尺寸有关。三分之二造成伤害的碰撞涉及一辆摩托车和另一辆机动车。摩托车碰撞最常发生在下午和傍晚时分以及夏季，但碰撞发生率的峰值出现在包含节假日的几周内。
