CARRYING BACKPACKS & BACKPACK
40 million teenagers carry a backpack to school each day. While carrying a backpack to school every morning
may seem harmless enough, it can cause painful back and neck problems and injuries for students who don’t pack or carry
their backpacks properly. It can also lead to long-term health problems. In fact, more and more chiropractic doctors and medical
doctors are seeing children for back pain and injuries.
It is advised that individuals carry no more than 15% of their body weight on their backs. Health professionals advise that individuals carry
no more than 10-15% of their body weight on their backs.
Example: A child weighing:
- 50 lbs. should carry no more than 7.5 lbs.
- 80 lbs. should carry no more than 12 lbs.
- 100 lbs. should carry no more than 15 lbs.
- 130 lbs. should carry no more than 19.5 lbs.
- 150 lbs. should carry no more than 22.5 lbs.
Many children are carrying up to 40 lbs. and are hurting themselves with spinal subluxations, muscle
and ligament sprains and strains. Today’s heavy loads are causing injuries
that last a lifetime.
- A study by
Northeastern University (June, 01) reported that the average student has a VAS (visual analog scale) pain level of 4.3 with
a high percent reporting pain in the range of 8-9. The students who wore an AirPacks backpack for six weeks had a VAS pain
level of 1.8, a 50% reduction in pain.
- A study by Simmons College (February, 2001) found that
55% of students carry more than the recommended guidelines of 10 – 15%
- In November
‘99 the American Physical Therapy Association issued a statement concerning backpack injury.
- When 200
New England school nurses were surveyed, 66% reported seeing students with pain or injury that cold be attributed to carrying
backpacks that were too heavy.
- It typically puts them off balance and gives them a posture
that promotes low back pain,” said Dr. Wayne Yankus of the American Academy of Pediatrics’ Committee on School
Health. “A lot of kids don’t suffer it immediately, but over the long run they might.”
In October, 99 the American Academy
of Orthopedics stated that “of the more than 100 physicians surveyed”:
- 71% felt that backpacks are a clinical problem for children
- 58% have seen patients complaining of back or shoulder
pain related to backpacks
- 65% have recommended that a patient modify the use of
a backpack to improve or correct a back problem
- 52% feel that backpack injury is a significant problem
- Survey was conducted amongst physicians from Children’s
Memorial Hospital, Chicago, IL and Alfred I. DuPont Hospital for Children, Wilmington, DE
· In November ‘98 the Consumer Product Safety Commission issued a warning concerning
injuries related to backpacks. The commission estimated that “3,300 children aged 5 to 14 were treated in emergency
rooms last year for injuries related to bookbags”.
· An Auburn University study reported that heavy
backpacks might be a threat to spinal development. In their survey sample, the average pack was 17% of the child’s weight.
67.2% of the children studied suffered muscle soreness, 50.8% back pain, 24.5% numbness and 14.7% shoulder pain.
· Studies at Johns Hopkins Children Center show overloaded backpacks as the cause of shoulder
or lower-back pain and poor posture.
· University of Michigan researchers estimate that up to 60% of children will experience
back pain by the time they reach 18.
· National Public Radio reported that 65% of adolescents' visits to the doctor are for backpack
related injuries (October, ‘98).
· Over the past four years, local television and print have extensively covered this topic.
This has included coverage by the New York Times, NBC Today Show, Good Morning America, CBS Morning Show, National Public
Radio, Time Magazine, ParentsMagazine, Consumers Report and Good Housekeeping.
· The current student backpacks do not provide the ergonomic support necessary to prevent
back injury for students carrying the average 30 lbs. of books.
· Older students (12-18 years) magnify this
back injury problem by carrying their backpacks with one strap (on one shoulder) instead of two, directing the weight to one
side of the body. There is evidence that this encourages scoliosis and other permanent physical problems.
· Currently the industry is fashion focused and has ignored the many consumer and professional
concerns regarding the ergonomics of packs. The backpack manufacturers are sidestepping the issue and blaming this problem
on schools and the increased academics that require students to lug around more than 10% (as much as 40%) of their body weight.
The market leaders, Jansport and LL Bean are concerned with the liability associated with addressing this problem.
