Key clinical point: A healthy lifestyle was associated with a reduced risk of developing rheumatoid arthritis (RA) overall, as well as for seropositive and seronegative RA.
Major finding: Each unit increase in healthy lifestyle index score was associated with a reduced risk for overall RA (hazard ratio [HR] 0.86; P < .0001), seropositive RA (HR 0.85; P < .0001), and seronegative RA (HR 0.87; P < .001).
Study details: The findings come from an analysis of 2 large prospective cohorts including 107,092 women, among which 1,219 cases of incident RA (seropositive, 776; seronegative, 443) were identified.
Disclosures: The study was supported by the National Institutes of Health and Rheumatology Research Foundation Career Development Bridge Award. The authors declared no conflicts of interest.
