The American Academy of Pediatrics has recommended that opportunities for non-tackling American football (e.g., flag football) be expanded, given concerns about the risks of brain trauma from tackle football. This study tested the hypothesis that flag football would be more accessible in communities characterised by higher socioeconomic status residents.
In July 2017, the locations of community-based organisations offering youth flag and tackle football for youth between the ages of 6 and 13 in two US states (Georgia and Washington) were aggregated (n=440). Organisations were coded in terms of the availability of tackle and/or flag football teams for youth at each year of age between 6 and 13. Multivariate logistic regression analyses were used to assess the odds of a community-based football organisation offering flag football, by community socioeconomic and demographic characteristics.
In both states, communities with more educated residents were more likely to offer flag football for youth aged 6-12. For example, among 6 year-olds every 10% increase in the number of adult residents with a college education was associated with 1.51 times the odds of flag football availability (95% CI 1.22 to 1.86, P<0.001).
These results suggest that youth living in communities characterised by low educational attainment are less likely than other youth to have the option of a lower contact alternative to tackle football. Relying on voluntary community-level adoption of lower contact alternatives to tackle football may result in inequitable access to such sport options. This may contribute to an inequitable burden of brain trauma from youth sport.
鉴于人们对触身式美式橄榄球(tackle football)导致脑外伤风险的担忧,美国儿科学会建议扩大非触身式美式橄榄球(如腰旗橄榄球)的机会。本研究检验了以下假设,即社区中社会经济地位较高的居民更有可能参与腰旗橄榄球。
2017 年 7 月,汇总了美国两个州(佐治亚州和华盛顿州)提供面向 6 至 13 岁儿童的社区组织开展青少年腰旗和触身式橄榄球的位置(n=440)。按照社区内 6 至 13 岁各年龄段提供青少年触身式和/或腰旗橄榄球队的情况对组织进行编码。采用多变量逻辑回归分析评估了社区内橄榄球组织提供腰旗橄榄球的可能性与社区社会经济和人口特征之间的关系。
在两个州,居民受教育程度较高的社区更有可能为 6 至 12 岁的儿童提供腰旗橄榄球。例如,在 6 岁儿童中,每增加 10%具有大学学历的成年居民人数,与腰旗橄榄球可获得性的几率增加 1.51 倍(95%CI 1.22 至 1.86,P<0.001)。
这些结果表明,与其他儿童相比,生活在受教育程度较低的社区中的青少年选择触身式橄榄球的低接触替代方案的可能性较小。依赖社区层面自愿采用低接触替代触身式橄榄球可能会导致获得此类运动选择的机会不平等。这可能导致青少年运动中脑外伤的负担不公平。
