Key clinical point: The use of oral contraceptives (OC) appeared to be protective against rheumatoid arthritis (RA), whereas the use of menopausal hormone therapy (MHT) increased the risk for late-onset RA.
Major finding: Compared with never-use, ever-use (hazard ratio [HR] 0.89; 95% CI 0.82-0.96) and current-use (HR 0.81; 95% CI 0.73-0.91) of OC decreased the risk for RA, whereas ever-use (HR 1.16; 95% CI 1.06-1.26) and former-use (HR 1.13; 95% CI 1.03-1.24) of MHT increased the risk for late-onset RA.
Study details: This prospective cohort study included 239,785 British women whose data were evaluated for the effect of OC (n = 236,602) or MHT (age ≥ 60 years, n = 102,466) on RA risk.
Disclosures: This study was funded by Agnes and Mac Rudbergs Foundation (Sweden), the Åke Wiberg Foundation (Sweden), the Marcus Borgström Foundation (Sweden), and various other sources. The authors declared no conflicts of interest.
