The objectives of this cohort study were to examine the rate, types, mechanisms and risk factors for injury in female youth (ages 9-17) ice hockey players in the Girls Hockey Calgary Association.
The main outcome was ice hockey injury, defined as any injury occurring during the 2008/2009 season that required medical attention, and/or removal from a session and/or missing a subsequent session. Potential risk factors included age group, level of play, previous injury, ice hockey experience, physical activity level, weight, height, position of play and menarche. Incidence rate ratios (IRR) were estimated with Poisson Regression adjusted for cluster (team). Exposure data were collected for every session for each participating player.
Twenty-eight teams (n=324) from Atom (ages 9-10), PeeWee (11-12), Bantam (13-14) and Midget (15-17) participated with 53 reported injuries. The overall injury rate was 1.9 injuries/1000 player-hours (95% CI 1.4 to 2.7). Previous injury (IRR=2.7, 95% CI 1.7 to 4.3), games (IRR=2.1, 95% CI 1.1 to 4.2), menarche (PeeWee) (IRR=4.1, 95% CI 1.0 to 16.8) were significant risk factors. In Midget, the more elite divisions were associated with a lower injury risk (A-IRR=0.2, 95% CI 0.1 to 0.5) (AAA-IRR=0.5, 95% CI 0.2 to 0.9).
Injury rates were lower in this study than previously found in male youth and women's ice hockey populations. Previous injury and game play as risk factors are consistent with the literature. Menarche as a risk factor is a new finding in this study. This research will inform future studies of the development of injury prevention strategies in this population.
本队列研究的目的是调查在卡尔加里女子曲棍球协会中，9-17 岁女性青少年冰球运动员的受伤率、类型、机制和危险因素。
主要结局是冰球损伤，定义为在 2008/2009 赛季期间发生的任何需要医疗关注和/或从某一场比赛中被移除和/或错过后续比赛的损伤。潜在的危险因素包括年龄组、比赛级别、既往损伤、冰球经验、身体活动水平、体重、身高、比赛位置和初潮。使用泊松回归估计发病率比（IRR），并根据团队进行了调整。为每个参赛运动员的每个比赛场次收集暴露数据。
共有 28 支球队（n=324）参加了原子组（9-10 岁）、 peewee 组（11-12 岁）、 bantam 组（13-14 岁）和 midget 组（15-17 岁），报告了 53 例损伤。总体损伤率为 1.9 例/1000 名运动员-小时（95%CI 1.4-2.7）。既往损伤（IRR=2.7，95%CI 1.7-4.3）、比赛（IRR=2.1，95%CI 1.1-4.2）、初潮（peewee）（IRR=4.1，95%CI 1.0-16.8）是显著的危险因素。在 midget 组中，更高级别的分区与较低的损伤风险相关（A-IRR=0.2，95%CI 0.1-0.5）（AAA-IRR=0.5，95%CI 0.2-0.9）。
与之前在男性青少年和女性冰球人群中发现的相比，本研究中的损伤率较低。既往损伤和比赛是危险因素，这与文献一致。初潮作为危险因素是本研究中的一个新发现。这项研究将为该人群中损伤预防策略的发展提供信息。
