The Prevalence of Back Pain in School Kids Who Use Backpacks
While back pain is a known and widely-studied issue in adults, its prevalence in school-aged children has received comparatively little scientific attention. Elementary, middle, and high school students must often carry backpacks that weigh enough to cause chronic back pain, poor posture, and even decreased lung volume. Recently, several studies reveal the truths behind childhood back pain and ways to mitigate it.
Are Backpacks Too Heavy for Kids?
Recent research supports that children carrying backpack loads of more than ten percent of their bodyweight have a greater risk of developing back pain and related issues. An international study found that an alarmingly large proportion of school-aged children in Australia, France, Italy, and the United States regularly carried backpacks weighing more than the ten percent threshold.
In another study involving a sample of 1540 metropolitan school-aged children, over a third of the children surveyed reported back pain. In addition to carrying heavy backpacks, female students and those diagnosed with scoliosis had a greater association with back pain. Children with access to lockers reported less pain.
The number of straps on the backpack had little impact on the respondents’ answers. Children also reported limited physical activity due to back pain, and some took medication to relieve the pain.
Girls who carried purses in addition to wearing a backpack reported significantly greater back pain. Adolescents with back pain spent more time watching television than their peers. Over 80 percent of those surveyed believed that carrying a heavy backpack caused their back pain.
Proper Backpack Carrying Techniques
The studies revealed several factors that may help reduce back pain in school-aged children. The best way to prevent back pain is to avoid carrying heavy loads.
Children should take advantage of locker breaks and only carry items necessary for a couple of classes at a time. When lifting a backpack, children should crouch down and bend their knees rather than curve the spine.
While not conclusive, research also supports that carrying the weight differently, e.g., by hand rather than by backpack, may help prevent or reduce back pain. The American Occupational Therapy Association and the offer these additional safe backpack etiquette tips:
- Children should avoid carrying over 10 percent of their bodyweight in their backpack. For example, an 8th-grader weighing 120 pounds should carry no more than 12 pounds.
- Place the heaviest objects at the back of the pack.
- Make sure the items fit as snugly as possible to minimize back pain due to shifting weight.
- Adjust the shoulder straps so they fit snugly over your child’s shoulders and the backpack doesn’t drag your child backward. The bottom of the pack should be less than four inches below your child’s waist.
- Children should avoid carrying backpacks slung over one shoulder, as it can cause spinal pain and general discomfort.
- Encourage your child to carry only necessary items in their backpack. Additional items can be carried in hand.
- Look for backpacks with helpful features such as multiple compartments for even weight distribution, padded straps to protect the shoulders and neck, and waist belt.
- If your child’s school allows, consider a rollerpack, which rolls across the floor like a suitcase.
- If problems continue, talk to your child’s teacher or principal about implementing paperback textbooks, lighter materials, or digital versions.
