To evaluate whether helmeted bicyclists are more compliant with traffic regulations than nonhelmeted bicyclists.
This prospective observational study, using a convenience sample, was conducted during daylight hours at three separate intersections, marked with legal stop signs, near the campus of a major university. Data collected included helmet use, legal hand signal use to indicate a turn or stop, and whether the bicyclist came to a complete stop before proceeding through the intersection.
A total of 1,793 bicyclists were evaluated. Only 8.8% of the bicycle riders were wearing helmets. Helmeted bicyclists were 2.6 times more likely than nonhelmeted bicyclists to make legal stops (P < .000001; odds ratio [OR], 3.1; 95% confidence interval [CI], 2.1 to 4.6). They were also 7.1 times more likely to use hand signals (P < .000001; OR, 7.2; 95% CI, 2.8 to 18.2).
Helmeted bicycle riders showed a significantly greater compliance with two traffic laws than nonhelmeted bicyclists. They were 2.6 times more likely to stop at stop signs and 7.1 times more likely to use legal hand signals. This very strong association of helmet use with safer riding habits has implications for injury-control efforts aimed at preventing bicycle-related injuries.
评估戴头盔的骑自行车者是否比不戴头盔的骑自行车者更遵守交通规则。
这项前瞻性观察性研究采用便利抽样，于白天在一所主要大学的校园附近三个设有法定停车标志的不同十字路口进行。收集的数据包括头盔使用情况、转弯或停车时使用法定手势信号的情况，以及骑自行车者在通过十字路口前是否完全停车。
共评估了1793名骑自行车者。只有8.8%的骑车者戴着头盔。戴头盔的骑自行车者完全停车的可能性是不戴头盔者的2.6倍（P <.000001；优势比[OR]为3.1；95%置信区间[CI]为2.1至4.6）。他们使用手势信号的可能性也高出7.1倍（P <.000001；OR为7.2；95%CI为2.8至18.2）。
戴头盔的骑自行车者比不戴头盔者在遵守两项交通法规方面表现出显著更高的依从性。他们在停车标志前停车的可能性高出2.6倍，使用法定手势信号的可能性高出7.1倍。头盔使用与更安全骑行习惯之间的这种非常强的关联对旨在预防与自行车相关伤害的伤害控制工作具有启示意义。
