PMID 36947671WHAT IT FOUND
In 159 women with fibromyalgia, 147 (92.45%) had at least one psychiatric disorder.
Sleep disorders were reported by 90.57% and mood disorders by 52.83%. This is prevalence, not proof that treating one condition improves the other.
Key findings
01In 159 women with fibromyalgia, 147 (92.45%) had at least one psychiatric disorder. Sleep disorders were present in 90.57% and mood disorders in 52.83%.
02Most patients had two or more psychiatric disorders, and mood and sleep disorders were diagnosed together in 32 patients (20.13%).
03Women with fibromyalgia and cluster-B personality disorders had higher odds of somatic symptom and related disorders, with adjusted odds ratio 2.9 (95% CI 1.19 to 7.26; p=0.019).

What it does not show
No control group, so the high rates cannot be compared with women without fibromyalgia or the general population. Psychiatric diagnoses came from one unscripted 45-minute interview, not a standardized semi-structured DSM-5 interview, so some disorders may have been missed or misclassified. Only women aged 18 to 65 newly diagnosed with fibromyalgia at one private clinic in Iran were studied, so results may not apply to men, longer-standing fibromyalgia, other settings, or other countries. The study did not measure pain duration, pain intensity, or childhood trauma, which could affect psychiatric findings. The association with cluster-B personality disorders is cross-sectional and does not show cause.
Declared interests
The authors declared no conflicts of interest. The study was funded by Mazandaran University of Medical Sciences.
The easy way to misread this
Do not read the 92.45% prevalence as evidence that fibromyalgia causes psychiatric disorders. The study had no control group, used a single unstructured interview, and measured disorders at one time.
