Current smoking was inversely associated with case/control status in primary Sjögren syndrome (pSS), while body mass index (BMI) lacked any association, according to a recent population-based cohort study. Olmsted County, MN residents (n=106) diagnosed with pSS from 2000 to 2015 were compared to 3 controls without pSS and matched for age and sex. Researchers found:
- Current smokers were less likely to be pSS cases (odds ratio [OR] 0.34), while there was no association between former smoking and case/control status (OR 1.27) compared to never smokers.
- Smoking status was not associated with antinuclear antibody, anti-Sjögren-syndrome-related antigen A (anti-SSA), anti-Sjögren syndrome type B (anti-SSB), or rheumatoid factor positivity.
- OR for obesity was 0.79.
