A new report published in the December issue of Injury Prevention revealed a pattern of injuries: heavier children are more likely to hurt their arms and legs in a car accident. They are no more likely than others to be injured, but the risk of sustaining a serious extremity injury was more than 2.5 times as great for overweight or obese kids. The correlation persists even after adjusting for other risks such as failing to wear seat belts and riding in older cars (up to models from 1990).
The researchers reviewed records of 3,232 children ages 9 to 15 injured and suspect that obese children are more susceptible to bone fractures under any circumstances and perhaps the increased mass results in increased force of impact on the arms and legs. While there are no specific actions as a result from the study, this seems to add another assuring log to the fire building behind prevention efforts for childhood obesity.
