1/3 of US Children have back pain.
Re: 1/3 of US Children have back pain.
One thing I've seen that'd probably hurt their backs is that I've seen a lot of kids carrying their backpacks with only one shoulder, and some of the backpacks are even made that way. Wouldn't take a lot of weight to mess up your back that way, honestly.
