Although data exist on injuries in youth football leagues, there are limited recent data on injury incidence in middle school football. Updated injury incidence estimates can help drive the development of injury prevention strategies.
Describe the epidemiology of injuries in middle school football during school years 2015-2016 to 2017-2018.
Descriptive epidemiology study.
Data originated from 9 public middle schools in Virginia during school years 2015-2016 to 2017-2018. Certified athletic trainers collected injury and athlete-exposure (AE) data from school-sanctioned games and practices in boys', football. Injury counts and rates per 1000 AEs were calculated. Injury rate ratios with 95% CIs compared rates between games and practices.
Overall, 664 middle school boys', football injuries were reported, leading to an overall injury rate of 20.54 per 1000 AEs (95% CI, 18.98-22.11). The time loss injury rate (inclusive of injuries with participation restriction time ≥24 hours) was 9.28 per 1000 AEs (95% CI, 8.23-10.33). The injury rate was higher in competition than practice (36.19 vs 17.97 per 1000 AEs; injury rate ratio, 2.01; 95% CI, 1.69-2.40). Most injuries were to the head/face (competition, 20.6%; practice, 15.8%) and hand/wrist (competition, 18.8%; practice, 16.4%) and were diagnosed as contusions (competition, 30.9%; practice, 25.9%) and sprains (competition, 19.4%; practice, 12.6%). Competitions also had a large proportion of concussions (10.3%). Overall, 80.0% and 66.9% of injuries were due to contact in competition and practice, respectively; of these contact-related injuries, 62.1% and 41.6% were specifically player contact.
Injury distributions parallel those found in previous research from middle school and other sport settings. Injury rates in middle school football were higher than those reported in previous findings in high school and college. However, caution must be taken when interpreting findings in relation to other surveillance systems with varying methodologies. Still, the findings highlight the need for injury prevention strategies within middle school football, particularly as related to contact-related mechanisms.
尽管有关于青年足球联赛中受伤的资料，但最近关于中学足球受伤发生率的数据有限。更新的受伤发生率估计可以帮助推动制定预防策略。
描述 2015-2016 学年至 2017-2018 学年期间中学足球的受伤情况。
描述性流行病学研究。
数据来自弗吉尼亚州的 9 所公立中学，时间为 2015-2016 学年至 2017-2018 学年。经过认证的运动训练师从学校批准的男孩足球比赛和练习中收集受伤和运动员暴露（AE）数据。计算每 1000 次 AE 的受伤次数和比率。用 95%置信区间（CI）比较比赛和练习之间的比率。
总体而言，报告了 664 名中学男生足球受伤，总受伤率为每 1000 次 AE 20.54 次（95%CI，18.98-22.11）。失时伤的发生率（包括受伤后限制活动时间≥24 小时）为每 1000 次 AE 9.28 次（95%CI，8.23-10.33）。比赛中的受伤率高于练习（每 1000 次 AE 分别为 36.19 和 17.97；受伤率比，2.01；95%CI，1.69-2.40）。大多数受伤发生在头部/面部（比赛，20.6%；练习，15.8%）和手部/手腕（比赛，18.8%；练习，16.4%），并被诊断为挫伤（比赛，30.9%；练习，25.9%）和扭伤（比赛，19.4%；练习，12.6%）。比赛中也有很大比例的脑震荡（10.3%）。总体而言，80.0%和 66.9%的受伤是比赛和练习中的接触造成的；在这些接触相关的伤害中，62.1%和 41.6%是球员接触造成的。
受伤分布与之前从中学校园和其他运动环境中获得的研究结果相似。中学足球的受伤率高于之前在高中和大学发现的受伤率。然而，在与其他具有不同方法的监测系统的发现进行解释时，必须谨慎。尽管如此，这些发现还是强调了在中学足球中需要预防策略，特别是与接触相关的机制。
