Past research has linked heavy backpack use by children and teens with postural changes and an increased risk for musculoskeletal disorders. The results of a recent study indicates that a heavy backpack can also lead to problems for young adults. In the study, researchers assessed participants as they stood with no backpack and while wearing a backpack loaded with 5%, 10%, and 15% of their body weight. The investigators found carrying a backpack equivalent to 15% of one’s body weight leads to increased forward posture of the head on the neck, which could raise one’s risk for neck pain and headaches.
