New Research Shows Increase in Low Back Pain

Posted: Updated:

New research suggests an alarming rise in low back pain.

The number of low back pain sufferers has doubled In north carolina since the early 1990's, according to researchers in that state.

The U-N-C Chapel Hill study suggests this increase may indicate a similar trend across the country.

Low back pain is the second most common cause of disability in the US. It costs an estimated 100-billion dollars a year, mostly because of decreased wages and work productivity.

The reasons for the back pain trend are unclear, but researchers suggest it could be the rising obesity rate, depression and a better awareness of the condition.
