Sleep and Sleep Complaints in Juvenile Fibromyalgia Syndrome
Authors' conclusion
Sleep complaints are a key hallmark of JFS and have significant effect on relevant clinical domains of the disease, such as pain and depression.
Study context
- Population
- Consecutive patients with juvenile fibromyalgia syndrome (20 females, median age 15.7 yrs) and age-matched healthy controls25 patients
- Exposure
- Patients with juvenile fibromyalgia syndrome (JFS) vs age-matched healthy controls
- JFSn = 25
- Outcome
- Sleep quality in JFS (self-report measures and PSG sleep parameters, including N3 distribution index)
Methodological detailsconsecutive patients, age-matched healthy controls, full-night polysomnography
- Consecutive patients
- Age-matched healthy controls
- Full-night polysomnography
Main finding
As reported in the abstract
Sleep quality: nonrestorative sleep and PSG sleep parameters vs age-matched healthy controls
Nonrestorative sleep reported by 22 of 25 patients
88%
Observational data: associations, not effects.
