Backpacks are great for children to carry items back and forth from school to home, but backpacks that weigh more than 15 percent of a child’s body weight may cause health problems. In their Keeping Kids Healthy column, UTMB Drs. Sally Robinson and Keith Bly warn that neck, shoulder and back pain may develop from carrying a heavy backpack every day. When choosing a backpack, check to make sure that it has two wide, padded straps that fit over the child’s shoulders, a padded waist or chest belt that will distribute weight more evenly across the body, multiple compartments to distribute weight and does not have a width greater than the child’s chest.
