目的：确定影响颅脑损伤患者自行车伤严重程度的因素，以了解佩戴头盔的作用是否超出了头部保护的范围，探讨头盔对颅脑损伤的直接保护作用。使用广义线性模型检验年龄、性别、头盔使用、受伤原因、受伤年份、受伤地点以及是否发生在公共假期或学校假期对有颅脑损伤患者和无颅脑损伤患者的损伤严重程度评分(ISS)的影响。结果：影响颅脑损伤患者ISS的因素有：致伤原因(P=0.01)和使用头盔的趋势(P=0.06)。在非颅脑损伤组中，年龄(P=0.002.0 5)和意外地点(P=0.0 3)是影响ISS的显著因素。Logistic回归分析表明，ISS评分每增加1分，发生颅脑损伤的几率增加1.22倍(95%可信区间1.13~1.31)，使用头盔后发生颅脑损伤的几率降低0.48倍(95%可信区间0.23~1.03)。结论：头盔患者的损伤程度降低是因为对头部的保护，而不是对身体其他部位的保护。
Objectives: To identify factors that affect the severity of bicycle-related injuries in patients with head injury compared with those without, so as to find whether the effect of using helmets extends beyond head protection, and to explore a direct protective effect of helmets on head injuries.Methods: A total of 297 patients with bicycle-related injuries were studied. A generalized linear model was used to test the effect of age, sex:, helmet use, cause of injury, year of injury, place of injury and whether the injury occurred on public or school holidays on the Injury Severity Score (ISS) in those patients who had head injury and those without. A logistic regression model was used to define the factors that contribute to head injury, while adjusting for ISS.Results: Factors affecting ISS in the generalized linear model in those who had head injury were: cause of injury (P= 0.01) and there was a trend for helmet use (P= 0.06). The significant factors that have affected ISS in the no head injury group were age (P= 0.002) and place of accident (P= 0.03). Logistic regression has shown that with each increase of 1 point in the ISS the odds of head injury increases by a factor of 1.22 (95% confidence interval 1.13-1.31) and the use of helmets reduces the odds of head injury by a factor of 0.48 (95% confidence interval 0.23-1.03).Conclusions: The reduced severity of injury in helmeted patients is because of protection of the head and not other body regions.
