Fibromyalgia and risk of all-cause, specific mortality: A meta-analysis of observational studies
Abstract
Objectives
To evaluate the risk of all-cause, specific mortality among patients with fibromyalgia, which is a controversial topic.
Methods
We conducted a thorough search for cohort studies across the PubMed, Cochrane Library, and Embase databases, from their inception to 1 March 2023, using medical subject headings and relevant keywords. All data were meticulously analyzed using Stata statistical software version 16.0. The protocol was registered on PROSPERO (CRD42023402337).
Results
After analyzing seven cohort studies involving 152 933 individuals published between 2001 and 2020, we found no clear evidence linking fibromyalgia or widespread pain to all-cause mortality risk (odds ratio [OR] 1.11, 95% confidence interval [CI] 0.81–1.53; I2 = 82.6%, p = .505). However, our subgroup analysis revealed that the risk of suicide was significantly higher in fibromyalgia patients compared with non-fibromyalgia patients (OR 5.39, 95% CI 2.16–13.43; I2 = 69.9%, p < .05).
Conclusions
Our research did not discover any proof indicating a link between fibromyalgia or widespread pain and all-cause mortality. However, it is worth noting that there may be a potential correlation between individuals with fibromyalgia or widespread pain and a higher likelihood of suicide. As we had a limited number of participants in our study, further research is necessary to thoroughly investigate the relationship between these factors.
