In recent years there has been a significant increase in mortality among motorcyclists, especially older riders (40+ years). However, few studies have compared the nature and severity of injuries sustained by older vs. younger cyclists. The purpose of this analysis was to determine differences, if any, in injury patterns to older vs. younger motorcyclists and to explore rider, vehicle, and environmental factors associated with these differences. Older riders were found to have a significantly higher incidence of thoracic injury, especially multiple thoracic injuries, and specifically multiple rib fractures. Older motorcyclists were also more likely to ride larger motorcycles, and were more involved in collisions involving overturning or striking highway structures. Large engine sizes were associated with increased risk of head and thoracic injuries, but not abdominal injuries. The magnitude of increased risks related to 1000+ cc engine size was higher among older motorcyclists than younger motorcyclists.
近年来，摩托车骑行者的死亡率显著上升，尤其是年龄较大的骑行者（40岁及以上）。然而，很少有研究比较过老年与年轻骑行者受伤的性质和严重程度。本分析的目的是确定老年与年轻摩托车骑行者的损伤模式是否存在差异，并探讨与这些差异相关的骑行者、车辆和环境因素。研究发现，老年骑行者胸部受伤的发生率显著更高，尤其是多处胸部损伤，特别是多根肋骨骨折。老年摩托车骑行者也更有可能骑更大的摩托车，并且更多地卷入涉及翻车或撞上公路设施的碰撞事故。大发动机尺寸与头部和胸部受伤风险增加有关，但与腹部受伤无关。与1000 cc及以上发动机尺寸相关的风险增加幅度在老年摩托车骑行者中比年轻摩托车骑行者更高。
