To determine the incidence of concussion in high school rugby players and compare the findings with the relevant published literature. DESIGN AND SETTING: Prospective data collection in one US high school rugby program. SUBJECTS: Two teams followed for 3 years. MEASUREMENTS: Injury rate, injury severity, and time withheld from competition. RESULTS: Seventeen concussions were recorded, accounting for 25% of all reported injuries. The incidence rate for concussion was 3.8 per 1000 athlete-exposures (95% confidence interval, 2.0-5.7) or 11.3 per 100 player-seasons (95% confidence interval, 5.9-16.7). Of the 17 concussions, 14 were Cantu grade 1, 2 were grade 2, and 1 was grade 3. Concussions accounted for 25% of all days lost from rugby participation due to injury. CONCLUSIONS: The incidence of concussion in this study was higher than previously reported in other studies. Methodologic limitations and administrative rules that required suspension for injured players may have suppressed reporting in previous epidemiologic studies. The incidence of concussion in rugby is probably much higher than previously suggested.
确定美国高中橄榄球运动员脑震荡的发生率，并将研究结果与相关已发表文献进行比较。
在美国一个高中橄榄球项目中进行前瞻性数据收集。
两支球队，随访3年。
受伤率、损伤严重程度以及禁赛时间。
记录到17例脑震荡，占所有报告损伤的25%。脑震荡的发生率为每1000运动员暴露场次3.8例（95%置信区间，2.0 - 5.7）或每100球员赛季11.3例（95%置信区间，5.9 - 16.7）。在这17例脑震荡中，14例为坎图1级，2例为2级，1例为3级。脑震荡占因伤导致无法参加橄榄球运动的所有天数的25%。
本研究中脑震荡的发生率高于以往其他研究报告。方法学上的局限性以及要求受伤球员禁赛的管理规定可能导致以往流行病学研究中报告率偏低。橄榄球运动中脑震荡的发生率可能远高于此前的推测。
