The number of bicycle-related injuries has risen significantly with the increased popularity of bicycle riding in Canada. The risk of injury is highest among children. To assess the magnitude of the problem and to identify the contributing factors we used a questionnaire, injury reports and patient charts to survey bicycle-related injuries among children brought to the emergency department of the Children's Hospital of Eastern Ontario, Ottawa, between May 1 and Sept. 30, 1988. The questionnaire was completed for 517 (91%) of the 568 children; 70% were boys, and the mean age was 9.4 years. Only 2% of the patients had been wearing a helmet at the time of injury, although 13% claimed to own one for cycling. Over 60% of the accidents were attributable to carelessness or poor bicycle control; mechanical failure and environmental hazards were minor factors. Over 80% of the injuries occurred within a kilometre of the child's home. Of the 97 children admitted to hospital 49% had head and skull injuries and 40% had limb fractures. Bicycle-related injuries represented 14.8% of all nonwinter (Apr. 1 to Oct. 31) trauma admissions among children 5 years or older. Our results further document bicycle-related injuries as an important childhood problem and underscore the need for improved safety measures.
随着骑自行车在加拿大越来越受欢迎，与自行车相关的伤害数量显著上升。儿童受伤风险最高。为评估该问题的严重程度并确定促成因素，我们于1988年5月1日至9月30日期间，使用问卷、伤害报告和患者病历，对被送往渥太华东安大略儿童医院急诊科的儿童中与自行车相关的伤害进行了调查。568名儿童中有517名（91%）完成了问卷；70%为男孩，平均年龄为9.4岁。受伤时只有2%的患者佩戴了头盔，尽管13%的人声称自己有自行车头盔。超过60%的事故归因于粗心或自行车操控不佳；机械故障和环境危害是次要因素。超过80%的伤害发生在孩子家一公里范围内。在97名住院儿童中，49%有头部和颅骨损伤，40%有肢体骨折。与自行车相关的伤害占5岁及以上儿童所有非冬季（4月1日至10月31日）创伤入院病例的14.8%。我们的结果进一步证明与自行车相关的伤害是一个重要的儿童问题，并强调需要改进安全措施。
