Prevalence of Fibromyalgia Syndrome in Saudi Arabia: A Systematic Review and Meta- Analysis

Background: The current systematic review and meta-analysis was conducted to estimate the prevalence of fibromyalgia syndrome in Saudi Arabia. Methods A PRISMA systematic search appraisal and meta-analysis were conducted. A systematic literature search of English publications in PubMed, Embase, PsycINFO, Web of Science, MEDLINE, and Google Scholar, was conducted up to December 2022. Generic, methodological and statistical data was extracted from the eligible studies. Meta-analysis was done using Comprehensive Meta-Analysis Software. The effect size estimates were calculated using the Fail-Safe N test. The funnel plot, Begg's and Mazumdar's rank correlation tests were employed to find any potential bias. The strength of the association between two variables is assessed using Kendall's tau. A fixed-effects model for the meta-analysis. Results The literature search yielded a total of 2479 studies. Eight papers were included in the final analysis with sample size ranging 40 to 1686. All studies were cross-sectional except two, which were retrospective. The total number of the participants recruited in the included articles was 4967 (1794 males and 3173 females); with age ranged between 20 to 79 years. There was high heterogeneity among studies articles (Q = 270.187; p-value 0.001); the tau value was 0.179. The pooled event rates and the 95% confidence intervals (CIs) for the prevalence of fibromyalgia syndrome in Saudi Arabia in a fixed-effects model was 13.4% (95% CI: 0.124–0.144). Conclusion Our results clearly demonstrates that fibromyalgia syndrome is highly prevalent (13.4%) in Saudi Arabia. It also more common among women. The high prevalence of fibromyalgia syndrome in Saudi Arabia should be seriously considered and planners should take steps to reduce it.
