OBJECTIVE
To investigate the use of helmets for cyclists choosing to use BIXI bikes in comparison to personal bike riders in the City of Toronto.
DESIGN
Cross-sectional study design.
SETTING
Cyclists were observed in Toronto, Canada.
PARTICIPANTS
Of the 6732 sample size, 306 cyclists on BIXI bikes and 6426 personal bike riders were observed.
OUTCOME MEASURE
The outcome of interest was helmet use.
RESULTS
Overall, 50.3% of cyclists wore helmets. The proportion of BIXI bike riders using helmets was significantly lower than the proportion of helmet users on personal bikes (20.9% vs 51.7%, respectively, p<0.0001).
CONCLUSIONS
Although the BIXI bike programme has provided an alternate means for Torontonians to use a bicycle, cyclists using BIXI bikes are much less likely to wear a helmet. Since the prevalence of helmet use in cyclists in general is already low, helmet use should be especially promoted in BIXI bike riders in order to promote a safe and healthy environment for cyclists.
目的
调查在多伦多市，选择使用比克自行车（BIXI bike）的骑行者与个人自行车骑行者相比头盔的使用情况。
设计
横断面研究设计。
地点
在加拿大多伦多对骑行者进行观察。
参与者
在6732个样本量中，观察了306名骑比克自行车的骑行者和6426名个人自行车骑行者。
观察指标
关注的结果是头盔的使用情况。
结果
总体而言，50.3%的骑行者佩戴头盔。骑比克自行车的骑行者使用头盔的比例显著低于个人自行车使用者中佩戴头盔的比例（分别为20.9%和51.7%，p<0.0001）。
结论
尽管比克自行车项目为多伦多人提供了一种替代的自行车出行方式，但骑比克自行车的骑行者佩戴头盔的可能性要小得多。鉴于一般骑行者中头盔的使用率本就较低，应特别倡导骑比克自行车的骑行者佩戴头盔，以营造安全健康的骑行环境。
