Key clinical point: Smoking worsened disease activity and health-related quality of life at 1 year in patients with rheumatoid arthritis (RA), with effects being persistent at 3 years and early smoking cessation vs. continued smoking being associated with improved disease activity.
Major finding: At 1 year, current smokers vs. non-smokers were at a higher risk for a swollen joint number above the median (odds ratio [OR] 1.7; P = .001) and 36-Item Short-Form Health Survey physical (OR 1.5; P = .006) and mental (OR 1.4; P = .03) scores below the median, with effects being persistent at 3 years. Patients who stopped vs. continued smoking within 1 year reported a lower swollen joint number (P = .002).
Study details: Findings are from a population-based case-control study including 1531 patients with newly diagnosed RA who were followed-up for 3 years, of which 376 patients were current smokers.
Disclosures: This study was supported by grants from the Swedish Medical Research Council and other sources. The authors declared no conflicts of interest.
