In North America, the use of off-road vehicles by young people is increasing, as are related injuries and fatalities. We examined the prevalence of off-road ridership and off-road helmet use in different subgroups of Canadian youth in order to better understand possible inequities associated with these health risk behaviors.
Data came from Cycle 6 (2009-2010) of the WHO Health Behavior in School-Aged Children Study (HBSC). Participants (n = 26,078) were young people from grades 6-10 in 436 Canadian schools. Students were asked, for a 12-mo recall period, how frequently they rode off-road vehicles and how often they wore a helmet while riding. Engagement in off-road ridership and helmet use were estimated by age group, gender, urban-rural geographic location, socioeconomic status, and how long participants had lived in Canada.
About half of the sample reported riding off-road vehicles (12,750; 52%). Among riders, 5,691 (45%) always wore helmets. Riders were more often older students, male and born in Canada. Students in rural areas and small towns were much more likely to ride off-road vehicles than their urban peers (RR, 95% CI: 1.28 [1.23-1.33]). Helmet use was less common among females, new immigrants, older students, and those in lower socioeconomic groups. There was little reported difference in helmet use by urban-rural location.
Risks associated with the use of off-road vehicles and with nonhelmet use are not equitably distributed across Canadian youth. Factors characterizing off-road ridership (notably urban-rural location) are distinct from factors for helmet use. Preventive interventions should target population subgroups.
在北美，年轻人越来越多地使用越野车，相关伤害和死亡人数也在增加。我们调查了不同年龄段的加拿大青少年越野骑行的流行率和越野头盔的使用情况，以便更好地了解与这些健康风险行为相关的不平等现象。
数据来自世界卫生组织 2009-2010 年学校儿童健康行为调查（HBSC）的第六周期。参与者（n=26078）是来自 436 所加拿大学校的 6-10 年级的青少年。学生被要求在 12 个月的回忆期内回答他们骑越野车的频率以及骑车时戴头盔的频率。通过年龄组、性别、城乡地理位置、社会经济地位以及参与者在加拿大居住的时间长短来估计参与越野骑行和戴头盔的情况。
大约一半的样本报告骑过越野车（12750；52%）。在骑车者中，5691 人（45%）总是戴头盔。骑车者往往是年龄较大的学生、男性和在加拿大出生的人。农村和小镇的学生比城市同龄人更有可能骑越野车（RR，95%CI：1.28 [1.23-1.33]）。女性、新移民、年龄较大的学生和社会经济地位较低的群体戴头盔的情况较少。城乡地理位置对头盔使用的影响差异不大。
与使用越野车和不戴头盔相关的风险在加拿大青少年中分布不均。与越野骑行相关的因素（特别是城乡地理位置）与头盔使用的因素不同。预防干预措施应针对人口亚组。
