To assess injury prevention measures used by cyclists in Oxford and to detect any differences between wearers and non-wearers of cycling helmets.
A prospective observational survey of a series of cyclists passing a single point on a busy city road in reduced lighting. Two observers jointly recorded four measures of injury prevention: use of front or rear light, high visibility (reflective or fluorescent) clothing, and cycling helmet. The use of the first three interventions was analysed in relation to helmet use/non-use.
A total of 392 cyclists were observed over one hour. Fourteen (3.6%) were observed to use all four studied measures, while 137 (34.9%) used none of them. The frequency of measures observed was: lit front light 190 (48.5%), lit rear light 197 (50.2%), both lights on 163 (41.6%), helmet on 104 (26.5%), and high visibility clothing 39 (9.9%). Despite the helmet using group's smaller size, it contained a significantly higher proportion of cyclists with lit front light (60.6% v 44.1%), lit rear light (61.5% v 46.2%), and high visibility clothing (27.9% v 3.5%), than the non-helmet group (p < or = 0.01). Whereas only 22% of the helmet users had no other observed measures, 47.2% of non-users did so.
Cycling helmet users were significantly more likely to use collision prevention measures in conditions of reduced visibility. Explanations may include higher levels of risk awareness and greater knowledge of safe cycling practices in the smaller, helmet using group. However, current measures by cyclists in a major cycling centre may be insufficient to prevent collisions and consequent serious injury or death.
评估牛津市骑自行车者所采用的伤害预防措施,并检测佩戴和未佩戴自行车头盔者之间的差异。
对一系列在光线较暗的繁忙城市道路上经过某一点的骑自行车者进行前瞻性观察调查。两名观察者共同记录四项伤害预防措施:使用前灯或后灯、穿着高可视性(反光或荧光)衣物以及佩戴自行车头盔。对前三项干预措施的使用情况与是否佩戴头盔进行了分析。
在一小时内共观察了392名骑自行车者。观察到14名(3.6%)使用了所有四项研究措施,而137名(34.9%)一项措施都未使用。观察到的措施使用频率如下:前灯亮190名(48.5%),后灯亮197名(50.2%),前后灯都亮163名(41.6%),戴头盔104名(26.5%),穿高可视性衣物39名(9.9%)。尽管戴头盔组规模较小,但与未戴头盔组相比,该组中前灯亮的骑自行车者比例(60.6%对44.1%)、后灯亮的比例(61.5%对46.2%)以及穿高可视性衣物的比例(27.9%对3.5%)显著更高(p≤0.01)。仅22%的头盔使用者没有其他观察到的措施,而未使用者中有47.2%没有其他措施。
在能见度降低的情况下,骑自行车时佩戴头盔的人更有可能采取防撞措施。原因可能包括规模较小的戴头盔组风险意识更高,以及对安全骑行做法的了解更多。然而,在一个主要的自行车中心,目前骑自行车者采取的措施可能不足以防止碰撞以及随之而来的严重伤害或死亡。
