A 2010 study from the University of California, San Diego, concluded, “backpack loads are responsible for a significant amount of back pain in children.” The same study says a full third of kids aged 11 to 14 report back pain. Other research from 2011 came to a similar conclusion.
Like the frame of a house, the spine(脊椎)is what keeps bodies strong and upright. Putting too much weight on this frame while a young body is still developing could change a child’s posture(姿势), compress(压缩) the spine, and harm children’s growth, says Rob Danoff, a doctor with Philadelphia’s Aria Health System. “It also might contribute to back problems or injuries when the child’s older,” he says.
Experts warn students against wearing a heavy backpack, adding something can be done to solve the problem.
