Most Teens With Fibromyalgia Have Pain as Adults
Four of five continued to experience symptoms, while half had full-blown disorder, study finds

WEDNESDAY, Feb. 26, 2014 (HealthDay News) -- Four out of five teens suffering from juvenile fibromyalgia will continue to have pain and other symptoms in adulthood, a new study finds.
About half of these children will end up as grown-ups with full-blown adult fibromyalgia, the researchers found.
"Half of the former teens we studied met the full criteria for adult fibromyalgia, and another 35 percent of them continued to have symptoms of fatigue, pain and sleep difficulty, but did not meet all the criteria for fibromyalgia syndrome," said study author Susmita Kashikar-Zuck, research director in behavioral medicine and clinical psychology at Cincinnati Children's Hospital Medical Center.
The study, published in the March print issue of Pediatrics, stemmed from research into juvenile fibromyalgia, Kashikar-Zuck said.
Fibromyalgia is a mysterious disorder that causes muscle pain and fatigue. People with the syndrome complain of sensitive places in their body that hurt when pressure is applied.
"It appears to be caused by a pain hypersensitivity in the central nervous system," Kashikar-Zuck said. "It's sort of like the volume is turned up on pain, and now they are exquisitely sensitive to pain."
Doctors aren't certain what causes fibromyalgia, although genetics may play a role. "Many of the children we see who have fibromyalgia have a parent with fibromyalgia," Kashikar-Zuck noted.
Between 80 percent and 90 percent of fibromyalgia patients are female, according to the U.S. National Institutes of Health.
Juvenile fibromyalgia can drastically affect a teen's life, causing missed school days and withdrawal from social activities, Kashikar-Zuck said.
Researchers wondered if these problems continued into adulthood, and decided to follow a group of 94 teenagers with juvenile fibromyalgia for six years. The teens were diagnosed with the disease between 2002 and 2010, with an average age at diagnosis of 15.
The study authors found that 51 percent of the patients, now young adults with an average age of 21, continued to have symptoms that meet the American College of Rheumatology's criteria for adult fibromyalgia.
More than one-third did not meet the standards for a full diagnosis but still complained of specific symptoms related to fibromyalgia. These included pain, fatigue and difficulty sleeping.
