To test the hypothesis that a history of traumatic brain injury (TBI) prior to the collegiate pre-season is associated with risk for re-injury. We also investigate sex differences, cognitive functioning, and self-reported concussion symptoms and their associations with concussion risk.
A longitudinal cohort study consisting of collegiate athletes ( = 212) who completed consecutive preseason evaluations (P1 and P2) between 2012 and 2015, averaging 12.9 (SD = 4.2) months apart.
There were 40 new concussions recorded between P1 and P2, 21 (53%) of which were among athletes who reported a lifetime history of mild TBI/concussion at P1. New P1-P2 concussions occurred in 24% of female athletes ( = 23) and 15% of male athletes ( = 17). History of TBI and female sex were significant predictors of new concussion between P1 and P2; however, in adjusted models, the inclusion of Impulse Control and PCSS Total symptom scores attenuated the effect of sex on the risk for new injury.
Collegiate athletes with a lifetime history of TBI had a significantly higher risk of sustaining a subsequent concussion. Pre-season emotional and somatic symptomology may contribute to incident concussion risk. The findings highlight the importance of considering lifetime head injury exposure and baseline symptomatology when interpreting sex differences and evaluating concussion risk.
检验以下假设，即大学生季前赛之前的创伤性脑损伤（TBI）史与再损伤风险相关。我们还研究了性别差异、认知功能以及自我报告的脑震荡症状及其与脑震荡风险的关系。
这是一项队列研究，纳入了 2012 年至 2015 年间完成连续季前评估（P1 和 P2）的大学生运动员（ = 212），两次评估平均间隔 12.9 个月（SD = 4.2）。
在 P1 和 P2 之间记录到 40 例新发脑震荡，其中 21 例（53%）发生在 P1 时报告有轻度 TBI/脑震荡既往史的运动员中。新发 P1-P2 脑震荡分别发生在 24%的女性运动员（ = 23）和 15%的男性运动员（ = 17）中。TBI 史和女性性别是 P1 和 P2 之间新发脑震荡的显著预测因素；然而，在调整后的模型中，冲动控制和 PCSS 总分症状的纳入削弱了性别对新损伤风险的影响。
有 TBI 既往史的大学生运动员发生后续脑震荡的风险显著增加。季前的情绪和躯体症状可能会增加脑震荡的风险。研究结果强调了在解释性别差异和评估脑震荡风险时，考虑终身头部受伤暴露和基线症状的重要性。
