Epidemiology of bicycle injury, head injury, and helmet use among children in British Columbia: a five year descriptive study

摘要

Objectives and methods—Data on 1462 injured bicyclists aged 1–19, obtained over a period of five years from the British Columbia Children's Hospital as part of a national emergency room based program in Canada, were analyzed to describe the epidemiology of injuries, helmet use, and the occurrence of head injuries before the enactment of a new mandatory helmet law. The odds ratio (OR) and 95% confidence interval (CI) were calculated for non-users compared with helmet users.
