To quantify the effects of wearing a helmet on head and facial injury among users of motorized two-wheel vehicles and to determine if helmet use increases the risk of neck and cervical spine injury.
DESIGN/METHOD: A population-based study involving injured riders from the Rhône Road Trauma Registry from 1996 to 2005. Victims were only included if they had an injury to a body region other than (or in addition to) the head, face, neck, or cervical spine. Thus, inclusion was not affected by helmet use by the rider. The risk of head, face, neck, and cervical spine injury was assessed, with helmet use as the exposure of interest using logistic regression analyses. Adjusted odds ratios and corresponding confidence intervals were calculated.
Helmet use significantly decreased the risk of head and facial injuries. The adjusted odds ratios for non-helmeted riders were 2.43 (95% CI 2.05 to 2.87) and 3.02 (95% CI 2.48 to 3.67), respectively. There was no association between helmet use and the occurrence of neck or cervical spine injuries. The adjusted odds ratios for non-helmeted riders were 0.86 (95% CI 0.60 to 1.23) and 1.04 (95% CI 0.78 to 1.39), respectively.
Helmets protect users of motorized two-wheel vehicles against head and facial injury without increasing the risk of neck or cervical spine injury.
量化佩戴头盔对电动两轮车使用者头部和面部损伤的影响，并确定使用头盔是否会增加颈部和颈椎损伤的风险。
设计/方法：一项基于人群的研究，涉及1996年至2005年来自罗纳道路创伤登记处的受伤骑手。仅当受害者除头部、面部、颈部或颈椎外（或除此之外）身体其他部位受伤时才纳入研究。因此，纳入不受骑手是否使用头盔的影响。以头盔使用作为感兴趣的暴露因素，采用逻辑回归分析评估头部、面部、颈部和颈椎损伤的风险。计算调整后的优势比和相应的置信区间。
使用头盔显著降低了头部和面部受伤的风险。未佩戴头盔的骑手调整后的优势比分别为2.43（95%可信区间2.05至2.87）和3.02（95%可信区间2.48至3.67）。头盔使用与颈部或颈椎损伤的发生之间没有关联。未佩戴头盔的骑手调整后的优势比分别为0.86（95%可信区间0.60至1.23）和1.04（95%可信区间0.78至1.39）。
头盔可保护电动两轮车使用者免受头部和面部损伤，而不会增加颈部或颈椎损伤的风险。
