To determine if there is an association between the risk of all injury or concussion and win-loss records or penalty minutes in competitive youth ice hockey players (ages 11-14).
DESIGN, SETTING, PARTICIPANTS: This is a secondary data analysis of a 2-year cohort study in Alberta and Quebec on the 2007/2008 (Pee Wee) and 2008/2009 (Bantam) seasons. Main outcome measures Incidence rate ratios (IRRs) were estimated based on Poisson regression for game-related injury and concussion and adjusted for cluster by team.
A total of 140 teams from Alberta (n=2081) and 137 teams (n=2018) from Quebec were included in the analysis. There were 451 game-related injuries (121 concussions) from Alberta and 280 (62 concussions) from Quebec. For game-related injuries, the IRR between players from teams with more than 50% wins and players with less or equal to 50% wins was 0.78 (95% CI 0.64-0.95) for all injuries, 0.75 (95% CI 0.52-1.08) for concussions, 0.64 (95% CI 0.47-0.88) for injuries resulting in time loss of more than 7 days, and 0.74 (95% CI 0.39-1.40) for concussions resulting in time loss of more than 10 days; adjusting for clustering by team and other important risk factors (i.e., province, age, level of play, previous injury, weight and position). There was no association found between the total penalty minutes per game and game-related injury or concussion.
There was a significant association found between team performance (i.e., win/loss/tie record) and injury risk with a 22% lower injury rate and 36% lower injury rate resulting in less than 7 days time loss in Pee Wee and Bantam ice hockey teams winning more than 50% of all season games. Total penalty minutes per game were not associated with injury or concussion rates.
确定在竞争激烈的青少年冰球运动员（年龄 11-14 岁）中，总受伤或脑震荡的风险是否与胜负记录或处罚分钟数有关。
设计、环境、参与者：这是对艾伯塔省和魁北克省 2007/2008 年（初级）和 2008/2009 年（初级 B）赛季的为期 2 年队列研究的二次数据分析。主要观察指标基于泊松回归估计了与比赛相关的损伤和脑震荡的发病率比值（IRR），并通过团队进行了聚类调整。
共纳入了来自艾伯塔省的 140 个队（n=2081）和来自魁北克省的 137 个队（n=2018）。艾伯塔省发生了 451 例与比赛相关的损伤（121 例脑震荡），魁北克省发生了 280 例（62 例脑震荡）。对于与比赛相关的损伤，胜率超过 50%的球队的球员与胜率低于或等于 50%的球队的球员之间的 IRR 为：所有损伤为 0.78（95%CI 0.64-0.95）、脑震荡为 0.75（95%CI 0.52-1.08）、需要超过 7 天时间才能康复的损伤为 0.64（95%CI 0.47-0.88）、需要超过 10 天时间才能康复的脑震荡为 0.74（95%CI 0.39-1.40）；调整了团队聚类和其他重要风险因素（即省份、年龄、比赛水平、先前损伤、体重和位置）。每场比赛的总处罚分钟数与与比赛相关的损伤或脑震荡之间没有关联。
胜率（即胜负记录）与受伤风险之间存在显著关联，胜率超过 50%的初级和初级 B 冰球球队的受伤率降低了 22%，需要少于 7 天康复时间的受伤率降低了 36%。每场比赛的总处罚分钟数与损伤或脑震荡发生率无关。
