There have been no large randomised controlled trials to determine whether soccer headgear reduces the incidence or severity of sport-related concussion (SRC) in US high school athletes.
We aimed to determine whether headgear reduces the incidence or severity (days out from soccer) of SRCs in soccer players.
2766 participants (67% female, age 15.6±1.2) (who undertook 3050 participant years) participated in this cluster randomised trial. Athletes in the headgear (HG) group wore headgear during the season, while those in the no headgear (NoHG) group did not. Staff recorded SRC and non-SRC injuries and soccer exposures. Multivariate Cox proportional hazards models were used to examine time-to-SRC between groups, while severity was compared with a Wilcoxon rank-sum test.
130 participants (5.3% female, 2.2% male) sustained an SRC. The incidence of SRC was not different between the HG and NoHG groups for males (HR: 2.00 (0.63-6.43) p=0.242) and females (HR: 0.86 (0.54-1.36) p=0.520). Days lost from SRC were not different (p=0.583) between the HG group (13.5 (11.0-018.8) days) and the NoHG group (13.0 (9.0-18.8) days).
Soccer headgear did not reduce the incidence or severity of SRC in high school soccer players.

在美国高中生运动员中，还没有大规模的随机对照试验来确定足球头盔是否能降低与运动相关的脑震荡（SRC）的发生率或严重程度。
我们旨在确定头盔是否能降低足球运动员中 SRC 的发生率或严重程度（从足球比赛中退出的天数）。
2766 名参与者（67%为女性，年龄 15.6±1.2 岁）（参加了 3050 名参与者年）参与了这项聚类随机试验。头盔组的运动员在整个赛季都戴头盔，而无头盔组的运动员则不戴头盔。工作人员记录 SRC 和非 SRC 损伤以及足球暴露情况。使用多变量 Cox 比例风险模型来检查两组之间的 SRC 发生时间，而严重程度则用 Wilcoxon 秩和检验进行比较。
130 名参与者（5.3%为女性，2.2%为男性）发生了 SRC。男性和女性中，头盔组和无头盔组的 SRC 发生率无差异（男性：HR：2.00（0.63-6.43）p=0.242；女性：HR：0.86（0.54-1.36）p=0.520）。SRC 造成的缺课天数在头盔组（13.5（11.0-018.8）天）和无头盔组（13.0（9.0-18.8）天）之间也无差异（p=0.583）。
足球头盔并没有降低高中足球运动员中 SRC 的发生率或严重程度。
