Concussion Rates in U.S. Middle School Athletes
ABSTRACT: Purpose: To investigate the epidemiology of concussions among middle school(MS) athletes. Methods: Athletic trainers recorded injury and athlete exposure (AE) data from public middle schools in Virginia. Concussion rates per 1000 AEs with 95% confidence intervals (CIs) were calculated for 12 school-sponsored sports Results: A total of 233 concussions were reported during 390,562 AEs attributed to school-sponsored sport participation (0.60/1,000 AE,95% CI=0.56-0.64). Overall concussion rate was higher in competition than practice. Among sex-comparable sports, concussion rates for girls were more than twice than boys. Conclusion: Football had the highest overall concussion rate among MS sports, consistent with prior literature. Our findings suggest that MS sports have an overall higher rate of concussion than reported in high school and collegiate settings.
