SAN DIEGO—It may seem counterintuitive, but young and middle-aged fibromyalgia patients report worse symptoms and poorer quality of life than older patients, a Mayo Clinic study shows.

 Fibromyalgia most often strikes women. It is characterized by widespread musculoskeletal pain with fatigue, sleep, memory and mood  issues. The research suggests the disorder plays out differently among different age groups.

Researchers studied 978 fibromyalgia patients and divided them into three age groups: those 39 or younger, those 40 to 59, and those 60 or older. The younger and middle-aged patients were likelier to be

employed, unmarried, smokers and have a higher education level, lower body mass index, more abuse history and a shorter duration of fibromyalgia symptoms than older patients.

“Among the three age groups of young, middle-aged and older, symptom severity and quality of life differs,” says senior author Terry Oh, M.D., a physical medicine and rehabilitation physician at Mayo Clinic in Rochester, Minn.

The study’s findings were surprising, because quality of life and physical health are considered to be negatively associated with age in the general population, Dr. Oh says.

Dr. Oh notes that women in all three groups with fibromyalgia reported a lower quality of life than

average U.S. women of similar age, and that the difference between their physical health and that of the average woman was more significant than mental health differences, particularly in young patients.

In other studies, Mayo researchers found:

•About 7 percent of fibromyalgia patients had inflammatory rheumatic conditions, and that in general,

those fibromyalgia patients didn’t do as well with treatment as those without rheumatic diseases.

• Fibromyalgia patients may also have skin-related symptoms such as excessive sweating or burning or other sensations.

• Obese patients with polymyalgia rheumatic have more pain and disability than other polymyalgia rheumatic patients. They also tend to need higher doses of  glucocorticoids.

•Rheumatoid arthritis patient experiences and symptoms do not always reflect what medical literature

shows when it comes to pain, morning stiffness, the relationship between swelling and damage, and

what worsens or improves symptoms. The study was led by researchers from the Rheumatoid Patient
