Sports-Related Concussions on the Rise in Kids
Study Shows Hockey and Football Lead Youth Sports in Number of Concussions
Aug. 30, 2010 -- The number of young children treated in hospital ERs for concussions they got while playing on sports teams has doubled in just a decade, a new study shows.
While the concussion rate is higher among high-school-age athletes, researchers say the rate among younger athletes is both significant and rising.
The study represents the first attempt to document the national incidence of sports-related concussions among children in elementary and middle school.
Concussions Most Common in Football, Hockey
The analysis of data from hospital emergency departments across the nation revealed that:
- Roughly half a million ER visits for concussions occurred among 8- to 19-year-olds between 2001 and 2005.
- About half were sports-related, and 40% of sports-related concussions involved children between the ages of 8 and 13.
- Football and ice hockey were the organized sports with the most concussion injuries, and snow skiing, bicycling, and playground injuries accounted for the most concussions occurring from non-team-related activities.
Even though participation in organized sports has declined slightly, team-related concussions doubled between 1997 and 2007 in 8- to 13-year-olds and more than doubled in older teens, Brown University pediatric emergency medical specialist Lisa L. Bakhos, MD, tells WebMD.
"We don't really know why this is," she says. "We know that kids are bigger now than they were in the past, which could be contributing to this trend. And sports seem to be more competitive."
Concussion Risk Higher for Girls
The study appears in the September issue of Pediatrics, along with a new report from the American Academy of Pediatrics (AAP) examining sports-related concussions in children and adolescents.
The report identified football as the organized sport most commonly associated with concussions.
It also confirmed that female athletes have a higher rate of concussions than boys who play similar sports. The reasons for this are not well understood.
One theory is that girls are more likely to sustain head injuries from a hit because they have weaker neck muscles, says pediatric sports injury specialist Mark E. Halstead, MD, of Children's Hospital St. Louis.
"In my experience, girls also tend to be more aggressive in their sports than guys," he tells WebMD. "That may also be a factor."
Long-Term Concussion Risks
Halstead says much more is known about the potential for long-term brain injury and even death from concussions today than a decade ago.
"When I started practicing sports medicine about 11 years ago it was common to send a kid with concussion symptoms back into a game 10 or 15 minutes after symptoms resolved," he says. "That doesn't happen as much these days."
He attributes this, in part, to the increased media spotlight on concussion-related deaths and brain injury among professional and varsity athletes.
The deaths of two North Carolina high school football players in less than two months in 2008 led that state to require a doctor's clearance before high school athletes can play or practice following a concussion.
