背景：2002年，加拿大曲棍球改变了未成年人冰球的年龄分类。在此之前，10岁和11岁的孩子在原子级别玩（没有身体检查），12岁和13岁的孩子在皮威级别玩（允许身体检查）。政策改变后，11岁的球员被安排在皮威区与12岁的球员;原子区包括9岁和10岁的球员。本研究的目的是检查的影响，政策的变化对11岁的球员受伤，并比较此信息与10岁和12岁的球员之间的受伤趋势。方法：研究的位置是首都健康区，服务于大埃德蒙顿地区在阿尔伯塔。首都健康维护着该地区所有急诊科就诊的数据库。对数据库的搜索确定了10岁、11岁和12岁的球员，他们在政策改变前2年和政策改变后2年因与钥匙有关的伤害而被送往7个急诊科。我们还对11岁的球员进行了图表审查，提取了同期他们受伤的性质和情况的详细信息。结果：11岁儿童在玩皮威级别游戏时受伤的比例与11岁的Atom级别球员相比，（率比[RR] 1.9，95%置信区间[CI] 1.4 - 2.4）。11岁Peewee球员的严重受伤率是11岁Atom球员的2倍多（RR 2.4，95%CI 1.6 - 3.6）。在研究期间，10岁的球员（身体检查从未被允许）和12岁的球员（身体检查总是被允许）的受伤率变化不大。解释：对11岁的球员进行身体检查与受伤率的大幅增加有关。从公共卫生的角度来看，在未成年人曲棍球中引入身体检查的年龄应该提高。
Background: In 2002, Hockey Canada changed the age classifications for minor ice hockey. Previously, 10- and 11-year-old children played at the Atom level (no bodychecking), and 12- and 13-year-old children played at the Peewee level ( bodychecking allowed). After the policy change, 11-year-old players were placed in the Peewee division with 12-year-old players; the Atom division included 9- and 10-year-old players. The objective of this study was to examine the effect that the policy change had on injuries to 11-year-old players and compare this information with injury trends among 10- and 12-year-old players.Methods: The study location was the Capital Health region, which serves the greater Edmonton area in Alberta. Capital Health maintains a database of all emergency department visits in the region. A search of the database identified 10-, 11- and 12-year-old players admitted to 7 emergency departments with hockey-related injuries during the 2 years before and the 2 years after the policy change. We also conducted a chart review for the 11- year- old players, extracting detailed information on the nature and circumstances of their injuries for the same period.Results: The rate of injuries sustained by 11-year-old children playing at the Peewee level (with bodychecking) increased significantly compared with the rate among 11-year- old players at the Atom level (rate ratio [RR] 1.9, 95% confidence interval [CI] 1.4 - 2.4). The rate of severe injuries was more than 2 times greater among 11- year- old Peewee players than among 11- year- old Atom players (RR 2.4, 95% CI 1.6 - 3.6). Injury rates among the 10-year-old players (bodychecking never allowed) and the 12-year-old players (bodychecking always allowed) changed little over the study period.Interpretation: The introduction of bodychecking to 11-year-old players was associated with a large increase in injury rates. From a public health perspective, the age at which bodychecking is introduced in minor hockey should be raised.
