The study, ” Sleep Disruption in Fibromyalgia: A Meta-Analysis of Case-control Studies ,” published in the Journal of Psychosomatic Research , reviewed several previously published studies reporting the contribution of sleep disorders in the development of fibromyalgia .
The benefits of a good night’s sleep have a positive impact on everyone’s physical and mental health. But according to the researchers, poor sleep affects nearly 80% of fibromyalgia patients, and studies have shown that lower sleep quality is a risk factor for fibromyalgia. In fact, poor sleep is strongly associated with the severity of symptoms: the less sleep patients have, the more severe their symptoms.
However, clinical studies with drugs have shown that improving sleep quality can reduce pain in patients with fibromyalgia.
To understand the characteristics of sleep disorders and their effects in patients with fibromyalgia, the researchers examined 25 case-control studies with a total of 2,086 participants and assessed their sleep by polysomnography (19 studies) and Pittsburgh Sleep Quality Index (19 studies). seven studies). .
Studies evaluating sleep with polysomnography have reported significant differences between patients with fibromyalgia and healthy individuals regarding waking time after sleep onset, total sleep time, and sleep efficiency between other parameters.
Studies evaluating sleep with the Pittsburgh Sleep Quality Index reported significant differences in overall scores, sleep onset latency, and sleep efficacy between the two groups of participants.
According to this study, fibromyalgia patients have difficulty falling asleep, have poor sleep quality and sleep efficiency, longer wake-up time after sleep, shorter sleep duration, and light sleep.
“Clinical trials have shown that improving sleep quality can reduce pain in people with fibromyalgia,” the researchers wrote. “Therefore, primary care providers should be informed by the results of this study and proactively assess the risk of sleep disturbance in patients complaining of generalized chronic pain or consider the diagnosis of fibromyalgia in these patients. Clinicians should also actively treat sleep disorders when low sleep is identified in people with fibromyalgia. ”
