Falls, bicycle crashes, burns, motorized vehicle accidents and near-drownings are the leading causes of hospitalization for American children during the summer, experts say.

These types of incidents are both predictable and preventable, according to Dr. Kathy Nuss, associate medical director of trauma services at Nationwide Children's Hospital in Columbus, Ohio, and colleagues.

Falls consistently top the list of causes of summertime injuries suffered by children. While objects such as trampolines are widely recognized as dangerous, children often suffer injuries from things considered much safer by parents, Nuss noted in a news release from the hospital.

"We see a lot of kids falling from playground equipment during the summer months. If possible, find playgrounds that are spread with mulch or shredded tire; these surfaces add more cushion versus concrete or blacktop," Nuss said the news release.

Bicycles are another major cause of injury. Nearly 400,000 children younger than 19 are treated at hospital emergency departments each year for bicycle-related injuries, according to the Center for Injury Research and Policy at Nationwide Children's. Injuries to the arms and legs are the most common, but head injuries are the most serious.

Nuss said children should always wear a helmet when riding a bicycle, use hand signals, and walk the bicycle across busy streets and intersections. Parents need to make sure the bike's seat and handlebars fit the child.
