This study aimed to determine the relationship between age of first exposure (AFE) to repetitive head impacts through contact/collision sports and patient-reported outcomes in community rugby players.
We recruited community rugby players older than 18 yr with at least 1 yr of contact rugby participation to complete an online survey. Participants completed the Brief Symptom Inventory-18 (BSI-18), Short-Form Health Survey 12 (SF-12), and Satisfaction with Life Scale (SWLS) via Qualtrics. We used generalized linear models to examine the association between AFE (continuous) and patient-reported outcomes by sex, while controlling for cumulative years contact/collision sport history, age, and concussion history (yes/no). In addition, we used Mann-Whitney U tests to compare patient-reported outcomes between AFE <12 and AFE ≥12.
A total of 1037 rugby players (31.6 ± 11.3 yr (range, 18-74 yr), 59.1% men) participated in this study. Whether analyzed continuously or dichotomously at age 12 yr, younger AFE was not associated with worse patient-reported outcomes for either men or women. Positive concussion history was a significant predictor of worse BSI-18 subscores, SF-12 subscores, and SWLS in women and worse BSI-18 subscores in men. Cumulative contact/collision sport history was a significant predictor of better BSI-18 Depression and SF-12 (Mental Component Summary) subscores in men only. In men and women, older age was a significant predictor of better BSI-18 Depression, Anxiety, and GSI subscores; better SWLS (in men only); and better SF-12 Mental Component Summary, but worse SF-12 (Physical Component Summary).
Younger AFE to contact/collision sport is not associated with worse patient-reported outcomes in early adult rugby players. Concussion history was predictive of worse patient-reported outcomes.
本研究旨在确定接触/碰撞性运动中首次接触（AFE）重复头部撞击的年龄与社区橄榄球运动员的患者报告结果之间的关系。
我们招募了年龄在 18 岁以上、有至少 1 年接触式橄榄球参与经历的社区橄榄球运动员，让他们完成一份在线调查。参与者通过 Qualtrics 完成了Brief Symptom Inventory-18（BSI-18）、Short-Form Health Survey 12（SF-12）和Satisfaction with Life Scale（SWLS）。我们使用广义线性模型，在控制累积接触/碰撞运动史、年龄和脑震荡史（是/否）的情况下，按性别检查 AFE（连续）与患者报告结果之间的关联。此外，我们使用 Mann-Whitney U 检验比较 AFE <12 与 AFE ≥12 的患者报告结果之间的差异。
共有 1037 名橄榄球运动员（31.6±11.3 岁（范围：18-74 岁），59.1%为男性）参与了这项研究。无论以连续变量还是以 12 岁为界的二分变量进行分析，较年轻的 AFE 与男性或女性的患者报告结果较差均无关联。阳性脑震荡史是女性 BSI-18 各分项评分、SF-12 各分项评分和 SWLS 较差的显著预测因子，也是男性 BSI-18 各分项评分较差的显著预测因子。累积接触/碰撞运动史是男性 BSI-18 抑郁和 SF-12（心理成分综合评分）各分项评分改善的唯一显著预测因子。在男性和女性中，年龄较大是 BSI-18 抑郁、焦虑和总体健康状况各分项评分改善、SWLS（仅男性）和 SF-12 心理成分综合评分改善的显著预测因子，但也是 SF-12（生理成分综合评分）较差的显著预测因子。
在早期成年橄榄球运动员中，接触/碰撞性运动中较年轻的 AFE 与患者报告结果较差无关。脑震荡史是患者报告结果较差的预测因子。
