228309 Epidemiology of Concussions Sustained in 18 US High School Sports, 2008-09Tuesday, November 9, 2010
Background/Purpose: An estimated 300,000 sport-related concussions occur annually in the United States (US). Recent research shows that young athletes are more susceptible to concussions than older athletes. The purpose of this study was to investigate the epidemiology of concussions in high school athletes by comparing concussion rates by sport, gender, and type of exposure.
Methods: Using an internet-based data collection tool, RIO™, certified athletic trainers from 200 US high schools reported athletic exposure and injury data for athletes participating in 18 sports during the 2008-09 academic year. Results: Concussions represented 11.8% of the 7,329 injuries reported. The overall concussion rate was 2.20 per 10,000 athlete exposures (AEs). Boys' football had the highest rate (5.35 concussions per 10,000 AEs), followed by boys' ice hockey (4.32), girls' lacrosse (3.94), and boys' lacrosse (3.22). Overall, girls had higher concussion rates than boys in gender-comparable sports (p<0.001), particularly in girls' softball compared to boys' baseball (RR=3.13, 95% CI=1.60-6.14, p< 0.001). Athletes were more likely to sustain concussions in competition than in practice (RR=6.49, 95% CI=5.62-7.50, p<0.001). 59.0% of all concussions resulted in a time loss of 1-3 weeks. Player-to-player contact was associated with 71.8% of concussions. Conclusions: Concussion rates vary by sport, gender, and type of exposure. An understanding of concussion rates, patterns of injury, and risk factors can drive targeted preventive measures and help reduce the risk for concussion among high school athletes.
