Psychiatric Comorbidities in Fibromyalgia: A Comparison With Chronic Conditions and Healthy Controls

Area of Science:

• Psychiatry
• Rheumatology
• Epidemiology

Background:

• Fibromyalgia is a chronic pain condition often accompanied by psychiatric issues.
• Limited comparative data exist on psychiatric comorbidities in fibromyalgia versus other chronic conditions.

Purpose of the Study:

• To compare psychiatric diagnoses and medication use in fibromyalgia patients against matched cohorts.
• To identify specific psychiatric risk patterns associated with fibromyalgia.

Main Methods:

• Retrospective cohort study of 5,040 individuals from a national healthcare provider.
• Matched groups included fibromyalgia, chronic pain, chronic fatigue syndrome, rheumatoid arthritis, and healthy controls.

Main Results:

• Psychiatric disorders were most prevalent in fibromyalgia patients.
• Anxiety (55.1%) and depression (48.7%) were predominant in fibromyalgia.
• Fibromyalgia showed significantly elevated risks for Cluster B personality disorders (RR=34), overall personality disorders (RR=24), and PTSD (RR=22.75).

Conclusions:

• Fibromyalgia patients face a substantially higher psychiatric comorbidity burden than other chronic conditions.
• Integrated, multidisciplinary care is essential for addressing fibromyalgia's unique psychiatric needs.
• This study provides direct comparisons and identifies distinct psychiatric risks in a diverse national cohort.
