The authors determined the incidence of concussion as well as correlates of grade II and grade III concussion among high school varsity football athletes. School team physicians completed an Internet-based incident card on their athletes who sustained a concussion on the field of play over three football seasons. Reported information included demographic data, school size, play position, game quarter of injury, and grade of concussion. A total of 70 concussions were reported on 981 eligible athletes for a cumulative incidence of 2.4 per 100 eligible players. The majority was grade II (52.9%). Most concussions occurred during the second (41.4%) and fourth (28.6%) quarters. The risk of concussion increased with increasing school size. After controlling for grade, weight, play position, and school size, playing during the fourth quarter was the only significant correlate of grade II and grade III concussion. Compared to playing during the first quarter, the risk of grade II and grade III concussion occurring during the fourth quarter was 8.7 (95% confidence interval, 1.2-64.2). Although the authors found a lower incidence of concussion than reported by others, they recommend that football coaches and team physicians be extra vigilant during the fourth quarter.
