背景：在之前的一项前瞻性研究中，在允许身体检查的联盟中，Pee Wee冰球运动员(11-12岁)脑震荡和所有受伤的风险是不允许检查的联盟中的三倍以上。我们研究了两年在Pee Wee的体检经验是否影响了Bantam联赛(13-14岁)球员的脑震荡和其他伤害的风险，并与13岁时首次开始体检的Bantam球员进行了比较。方法：我们对13-14岁的曲棍球运动员进行了前瞻性队列研究，这些球员在联盟中排名前30%的分区中。来自艾伯塔省(n=995)的68支球队，其球员在Pee Wee有两年的身体检查经验，以及来自魁北克省(n=976)的62支球队，其球员没有在Pee Wee的身体检查经验。结果：在有皮威体检经验的板凳曲棍球运动员中，共有272人受伤(51次脑震荡)，没有体检经验的人中有244人受伤(49次脑震荡)。在有皮威验身经验的球员和没有验身经验的球员之间，与游戏相关的伤害和脑震荡的调整IRR如下：总体受伤0.85(95%可信区间0.63至1.16)；总体脑震荡0.84(95%可信区间0.48至1.48)；以及受伤导致超过7天的时间损失(即受伤至重新上场之间的时间)0.67(95%可信区间0.46至0.99)。导致10天以上时间损失的脑震荡未经调整的IRR为0.60(95%CI 0.26至1.41)。解释：在皮威允许体检的联赛中，与13岁时首次开始体检的班坦曲棍球运动员相比，班坦曲棍球运动员因受伤导致超过7天比赛时间损失的风险降低了33%。鉴于皮威球员在允许体检的联赛中脑震荡和其他损伤的风险增加，关于曲棍球运动员被引入体检的年龄的政策需要进一步考虑。
Background: In a previous prospective study, the risk of concussion and all injury was more than threefold higher among Pee Wee ice hockey players (ages 11-12 years) in a league that allows bodychecking than among those in a league that does not. We examined whether two years of bodychecking experience in Pee Wee influenced the risk of concussion and other injury among players in a Bantam league (ages 13-14) compared with Bantam players introduced to bodychecking for the first time at age 13.Methods: We conducted a prospective cohort study in volving hockey players aged 13-14 years in the top 30% of divisions of play in their leagues. Sixty-eight teams from the province of Alberta (n = 995), whose players had two years of bodychecking experience in Pee Wee, and 62 teams from the province of Quebec (n = 976), whose players had no bodychecking experience in Pee Wee, participated. We estimated incidence rate ratios (IRRs) for injury and for concussion.Results: There were 272 injuries (51 concussions) among the Bantam hockey players who had bodychecking experience in Pee Wee and 244 injuries (49 concussions) among those without such experience. The adjusted IRRs for game-related injuries and concussion overall be tween players with bodychecking experience in Pee Wee and those without it were as follows: injury overall 0.85 (95% confidence interval [CI] 0.63 to 1.16); concussion overall 0.84 (95% CI 0.48 to 1.48); and injury resulting in more than seven days of time loss (i.e., time between injury and re turn to play) 0.67 (95% CI 0.46 to 0.99). The unadjusted IRR for concussion resulting in more than 10 days of time loss was 0.60 (95% CI 0.26 to 1.41).Interpretation: The risk of injury resulting in more than seven days of time loss from play was reduced by 33% among Bantam hockey players in a league where bodychecking was allowed two years earlier in Pee Wee compared with Bantam players introduced to bodychecking for the first time at age 13. In light of the increased risk of concussion and other injury among Pee Wee players in a league where bodychecking is permitted, policy regarding the age at which hockey players are introduced to bodychecking re quires further consideration.
