Fibromyalgia Linked With Disruptions in Sleep: Study

Scientists say fibromyalgia may be caused by poor sleep habits.

Fibromyalgia, previously believed to be attributable to genetics, infections, and emotional or physical trauma, may be caused by disruptions in the sleep cycle.

A chronic musculoskeletal condition that affects approximately 5 million adults, fibromyalgia affects 90 percent of women, according to U.S. News and World Report.

The condition is characterized by an achy pain, especially when pressure is applied to tender spots on the body.

The new study was conducted by researchers at the Norwegian University of Science and Technology.

The researchers found that 2.6 percent of women who previously had no musculoskeletal pain or movement disorders - but experienced significant sleep difficulties - developed fibromyalgia within a 10-year span, reports U.S. News and World.

The study also said that there is an increased risk for older women. The relative risk increased 2.4 percent for participants over the age of 45.

Study leader Dr. Paul Mork, from the Norwegian University of Science and Technology, said, "Our findings indicate a strong association between sleep disturbance and fibromyalgia risk in adult women,” reports U.S. and World News.

"We found a dose-response relation, where women who often reported sleep problems had a greater risk of fibromyalgia than those who never experienced sleep problems,” Mork said.

The study was published online in the journal Arthritis and Rheumatism: http://www.rheumatology.org/publications/ar/
