The 'trickle-down effect', or how major sports events have a positive impact on sports participation, has been the subject of many studies, but none produced conclusive results. We took a different approach and rather than look at sports participation, we used injuries as a proxy and see if injuries increased, or remained the same, after the International Federation of Association Football World Cup.
Using a retrospective cohort design, we looked at the injuries suffered by males and females (13-16 years old) while playing team sports in Montreal, that occurred in May to July, from 1999 to 2014. Information reported by the Canadian Hospitals Injury Reporting Prevention Program (CHIRPP) was limited to the two CHIRPP centres in Montreal: the Montreal Children's Hospital and Hopital Sainte-Justine.
In females, no significant trends were noticed. In males who played non-organised soccer, the percent changes between FIFA World Cup (WC) (June) and pre-FIFA WC (May) was always highest during FIFA WC years: 17.2% more injuries in years when FIFA WC was held compared to 1.3% less injuries during non-FIFA WC years. In non-organised soccer, male players suffered less strains/sprains (11.9% vs. 30.1%; P = 0.015), suffered more severe injuries (59.7% vs. 43.1%; P = 0.049) and more of their injuries were the results of direct contact with another player (26.8% vs. 13.3%; P = 0.028) during FIFA WC.
FIFA WC seems to have an impact on the injuries of teenage boys when playing non-organised soccer. The impact was short-lived, only lasting during the FIFA WC event.
“涓滴效应”，即重大体育赛事如何对体育参与产生积极影响，已成为众多研究的主题，但尚无定论。我们采用了不同的方法，不是关注体育参与情况，而是以受伤情况作为替代指标，观察在国际足球联合会世界杯之后受伤情况是增加了还是保持不变。
采用回顾性队列设计，我们研究了1999年至2014年5月至7月期间在蒙特利尔参加团队运动的13至16岁男性和女性所受的伤害。加拿大医院伤害报告预防项目（CHIRPP）报告的信息仅限于蒙特利尔的两个CHIRPP中心：蒙特利尔儿童医院和圣贾斯汀医院。
在女性中，未发现显著趋势。在参加非组织化足球运动的男性中，国际足联世界杯（6月）期间与世界杯前（5月）相比的百分比变化在世界杯举办年份总是最高：举办世界杯的年份受伤人数增加17.2%，而非世界杯举办年份受伤人数减少1.3%。在非组织化足球运动中，男性球员在世界杯期间遭受的拉伤/扭伤较少（11.9%对30.1%；P = 0.015），遭受的重伤较多（59.7%对43.1%；P = 0.049），且更多的受伤是与另一名球员直接接触的结果（26.8%对13.3%；P = 0.028）。
国际足联世界杯似乎对青少年男孩参加非组织化足球运动时的受伤情况有影响。这种影响是短暂的，仅在世界杯赛事期间持续。
