The risk of all-cause injury and concussion associated with football is significant. The National Football League (NFL) has implemented changes to increase player safety warranting investigation into the incidence and patterns of injury.
To document the incidence and patterns of all-cause injury and concussions in the NFL.
Descriptive epidemiology study.
Injury data were collected prospectively from official NFL injury reports over 2 regular seasons from 2012 to 2014, with identification of injury incidence rates and patterns. Concussion rate ratios were calculated using previously reported NFL rates.
A total of 4284 injuries were identified, including 301 concussions. The all-cause injury rate was 395.8 per 1000 athletes at risk (AAR) and concussion incidence was 27.8 per 1000 AAR. Only 2.3% of team games were injury free. Wide receivers, tight ends, and defensive backs had the highest incidence of injury and concussion. Concussion incidence was 1.61-fold higher in 2012 to 2014 compared with 2002 to 2007. The knee was injured most frequently, followed by the ankle, hamstring, shoulder, and head.
The incidence of all-cause injury and concussion in the NFL is significant. Concussion injury rates are higher than previous reports, potentially reflecting an improvement in recognition and awareness. Injury prevention efforts should continue to reduce the prevalence of injury associated with football.
足球运动导致的所有原因损伤和脑震荡的风险是巨大的。美国国家橄榄球联盟（NFL）已经采取了多项措施来提高球员的安全性，这值得对损伤的发生率和类型进行调查。
记录 NFL 中所有原因损伤和脑震荡的发生率和类型。
描述性流行病学研究。
通过 2012 年至 2014 年两个常规赛期间从官方 NFL 损伤报告中前瞻性地收集损伤数据，识别损伤发生率和类型。使用先前报道的 NFL 比率计算脑震荡的发生率比值。
共确定了 4284 例损伤，包括 301 例脑震荡。所有原因损伤的发生率为每 1000 名风险运动员 395.8 例，脑震荡发生率为每 1000 名风险运动员 27.8 例。仅有 2.3%的团队比赛没有受伤。外接手、近端锋和防守后卫的损伤和脑震荡发生率最高。与 2002 年至 2007 年相比，2012 年至 2014 年脑震荡的发生率高 1.61 倍。受伤最频繁的部位是膝盖，其次是脚踝、腿筋、肩膀和头部。
NFL 中所有原因损伤和脑震荡的发生率是显著的。脑震荡损伤的发生率高于以往的报告，这可能反映了对其认识和意识的提高。应继续努力预防损伤，以降低与足球相关的损伤的发生率。
