CARTERVILLE, IL (KFVS) - As children head back to school, some carrying big backpacks could face big problems.
Doctors say backpack weight is an increasing problem.
Studies show heavy backpacks can lead to both back pain and poor posture.
This painful trend among youngsters isn't surprising when you consider the amount of weight they carry in their backpacks often slung over just one shoulder.
But doctors say it can all be prevented.
"Of that 40 million, there is 20 million children that have backpacks on that have twice the amount of weight that is recommended, said Dr. Erich Snyder, a Chiropractor in Carterville, Illinois. "For example, we it's 10 percent is how we judge whether or not is suitable, so for example if a child weighs 100 pounds, the backpack should not exceed 10 pounds."
Doctor Snyder recommends looking for back packs with padded straps, lighten the load and to always use both straps.
