OBJECTIVE
In a retrospective cohort, we evaluated whether age beginning tackle football (ABTF) and more total years of playing football (TYPF) were associated with worse later-in-life neuropsychological change among older retired National Football League (NFL) players.
METHOD
Participants were 19 older NFL retirees aged 54-79, including 12 who returned for follow-up evaluation 15-51 months later. Mixed-linear models evaluated the association between ABTF/TYFP and baseline neuropsychological composite scores (executive functioning/attention/speed, language, memory), and neuropsychological composites over time.
RESULTS
ABTF and TYPF were not significantly associated with neuropsychological composites at baseline or over time (all p's > .05). There were no significant differences in neuropsychological performance between those ABTF <12 and ≥ 12 years old (all p's ≥ .475) or between those with TYPF <19 or ≥ 19 years played (median split; all p's ≥ .208).
CONCLUSIONS
Preliminary findings suggest that ABTF and TYPF does not worsen neurocognitive decline later-in-life among older NFL retirees.
目的
在一项回顾性队列研究中，我们评估了开始从事触身式橄榄球（ABTF）的年龄和参与触身式橄榄球的总年限（TYPF）是否与老年退役国家橄榄球联盟（NFL）球员晚年神经认知功能下降有关。
方法
参与者为 19 名年龄在 54-79 岁的老年 NFL 退役球员，其中 12 名在 15-51 个月后返回进行后续评估。混合线性模型评估了 ABTF/TYFP 与基线神经心理学综合评分（执行功能/注意力/速度、语言、记忆）以及随时间推移的神经心理学综合评分之间的关系。
结果
ABTF 和 TYPF 与基线或随时间推移的神经心理学综合评分均无显著相关性（所有 p 值均>0.05）。ABTF<12 岁和≥12 岁之间以及 TYPF<19 岁和≥19 岁之间的神经心理学表现无显著差异（所有 p 值均≥0.475）。
结论
初步研究结果表明，ABTF 和 TYPF 不会使老年 NFL 退役球员晚年的神经认知衰退恶化。
