In high school American football, girls are at nearly double the risk of concussion compared to boys, according to a new study. Girls are also less likely to be removed from play and take longer to recover from the injury than their male counterparts.
Researchers at the University of Pennsylvania and Michigan State University along with Prof Willie Stewart, Honorary Professor at the University of Glasgow reviewed three years of injury data for a population of around 40 000 female high school American footballers in the Michigan High School Athletic Association, comparing them to a similar number of their male counterparts.
They found that, as seen in previous studies, the risk of sports related concussion among female footballers was 1.88 times higher than among males. The researchers also identified several sex-associated differences in sports concussion mechanism and management. This provides new insight into this kind of injury in this demographic.
Male footballers tended to be injured in collisions with another player and were 1.5 times more likely than females to be removed from play on the day of injury. Female footballers were most often injured from impacts involving equipment, such as the ball or a goalpost, and also took on two days longer on average to recover from injury and return to play. A recent study however showed no differences for concussion recovery time among male and female college athletes, but there could be differences depending on the type of sport.
These sex-associated differences among teenage athletes in mechanism of injury and in management and outcomes of concussion raise the question of whether sports should consider the adoption of sex specific approaches to both participation and concussion management.
Lead author Dr Abigail Bretzin, postdoctoral fellow and certified athletic trainer at the University of Pennsylvania, said: “This is the first study to look in this detail at sex-associated differences in concussion management and outcomes in teenage footballers. Our findings add to research showing that female athletes are at increased concussion risk compared to male athletes, and highlight the importance of sex-specific research in this field.”
Senior author Prof Stewart, said: “Given we know the importance of immediate removal from play for any athlete with suspected concussion, it is notable that “if in doubt, sit them out” appears more likely to happen for boys than girls. This, together with the finding that mechanism of injury appears different between boys and girls, suggests that there might be value in sex-specific approaches to concussion education and management in this age group.”
