Rheumatoid arthritis (RA) is a chronic inflammatory joint disease that significantly impacts quality of life, particularly among women. Previous studies have suggested that oral contraceptive (OC) use may influence RA risk, but conflicting findings from earlier meta-analyses necessitate an updated analysis incorporating more recent data. We conducted a systematic review and meta-analysis of observational studies on OC use and RA risk by searching MedLine (via PubMed), Scopus, and Cochrane Databases up to September 2024. Our analysis demonstrated that current or prior use of OCs is associated with a statistically significant reduction in RA risk (OR 0.80, 95% CI 0.70-0.91). In contrast, the associations for current use (OR 0.59, 95% CI 0.34-1.02) and past use (OR 0.83, 95% CI 0.69-1.01) were less definitive, likely due to substantial heterogeneity among studies. Cumulative meta-analysis revealed a modest temporal trend toward a protective effect of OC use. This meta-analysis supports a protective association between current or prior OC use and the development of RA, highlighting the potential role of hormonal factors in RA pathogenesis.
