Injuries from wearing heavy backpacks are not common in school-aged children
***As a commenter below noted, as of 9/22/17 the link to the AOTA infographic with dubious information is broken/has been removed and now serves a 404 error. Hopefully this is an indication that there will be more care in the future about quoting statistics. The removal of the infographic does not address the question about whether or not there may be more impactful injury prevention efforts than concern with wearing heavy backpacks. (edited, 9/22/17, CJA). According to the American Occupational Therapy Association, heavy backpacks can cause serious injury to children. The AOTA claims that heavy loads carried by 79 million students across the United States "can cause low back pain that often lasts through adulthood." The AOTA also claims that according to 2013 statistics from the US Consumer Product Safety Commission nearly 22,200 strains, sprains, dislocations, and fractures from backpacks were treated in hospital emergency rooms, physicians' offices, and clinics.
