Introduction

The rising use of e-bikes (EBs) presents an opportunity to increase active transportation but may compromise road safety due to increased travel speed and weight compared to conventional bicycle (CBs). Evidence comparing the safety of EBs and CBs is limited while the influence of cyclists’ health status has been neglected.

Methods

This cross-sectional case-control study compared EB and CB users in the Netherlands. Data were gathered 1) through a survey among crash casualties treated at emergency departments aged >16 (N = 2383) and 2) control group data were collected among cyclists without any known crash experience, randomly drawn from a panel of the Dutch population (N = 1860). Using logistic regressions, we assessed the likelihood of crashes and crash severity while adjusting for bicycle use and health status.

Results

EB users had poorer health than CB users, but they were not more likely to be involved in a crash or to sustain more severe injuries. However, older female cyclists did have an elevated risk on EBs and sustained more severe injuries. Health-related factors such as the presence of morbid conditions, medication use, and the body mass index were neither associated with crash likelihood nor associated with injury severity and accordingly did not explain the findings for older females. However, balance and coordination problems, and the use of anti-epileptic drugs were associated with crashes.

Conclusion

Our findings provide support that EB users have a poorer health status than CB users, while general health status is unrelated to the likelihood and severity of bicycle crashes. EBs enable more vulnerable groups to cycle or keep cycling but, after controlling for bicycle use, EB users are not more likely to be involved in a crash or to sustain severe injuries. As older females run a higher risk on an EB and are more likely to fall while (dis)mounting, we recommend to promote EBs enabling safer (dis)mounting such as by reduced saddle height.

与传统自行车相比,电动自行车的安全性:骑车人的健康状况起什么作用?

介绍

与传统自行车(CB)相比,电动自行车(EB)的使用增加为增加主动交通提供了机会,但由于行驶速度和重量的增加,可能会损害道路安全。相比于EB和CB的安全性的证据是有限的,而骑自行车者的健康状况的影响却被忽略了。

方法

这项横断面的病例对照研究比较了荷兰的EB和CB用户。数据是通过以下方式收集的:1)通过对在> 16(N  = 2383)的急诊室接受治疗的撞车伤亡人数进行调查,以及2)在没有任何撞车经验的骑自行车者中收集了对照组数据,这些数据是从荷兰人群中随机抽取的(N  = 1860)。使用逻辑回归,我们在调整自行车使用和健康状况的同时评估了撞车的可能性和撞车的严重性。

结果

EB用户的健康状况不如CB用户,但他们不太可能卷入车祸或遭受更严重的伤害。但是,年龄较大的女性骑自行车者确实有较高的EB风险,并遭受了更严重的伤害。与健康相关的因素,例如病态的存在,药物的使用以及体重指数,都与崩溃的可能性无关,也与伤害的严重程度无关,因此也不能解释老年女性的发现。但是,平衡和协调问题以及使用抗癫痫药与崩溃有关。

结论

我们的研究结果支持EB用户的健康状况比CB用户差,而总体健康状况与自行车撞车的可能性和严重程度无关。EB可以使更多的弱势群体骑自行车或继续骑自行车,但是在控制自行车使用之后,EB使用者不太可能卷入车祸或遭受严重伤害。由于年龄较大的女性在EB上的风险较高,并且在(拆卸)时更容易摔倒,因此我们建议推广EB,例如通过降低鞍座高度来实现更安全的(拆卸)安装。
