Asthma, Allergic Disease, Passive Smoke Exposure & the Risk of RA

Passive smoke exposure at home or work was not associated with RA.

Finally, age at start of smoking was not associated with increased odds of developing RA in either the full cohort (OR 1.03 [95% CI 1.00–1.06; P=0.03]) or the incident RA cohort (OR 1.00 [95% CI 0.92–1.08; P=0.98]).

Conclusion

Asthma and allergies may be associated with increased risk of RA, but passive smoke exposure and early age at start of smoking do not appear to influence the risk of RA.

EULAR—Passive exposure to smoking during childhood or adulthood increases the risk of developing rheumatoid arthritis (RA), according to a large prospective cohort study of healthy French women presented during EULAR’s 2021 virtual European Congress of Rheumatology. Moreover, the association was mainly observed among women who had themselves never smoked.1 “In this study, we found an…

It’s no secret to any health professional, including rheumatologists, that smoking cigarettes or using other tobacco-based products is unhealthy. Yet how does smoking specifically affect rheumatic diseases, and what are some of the newest findings in this area? What role do e-cigarettes have in the smoking risk landscape? Those are the sorts of questions asked…

Recent research found women with COPD and asthma—even those who have never smoked—are at a higher risk of developing rheumatoid arthritis…

Systemic autoimmune diseases are thought to result from immune dysregulation in genetically susceptible individuals who were exposed to environmental risk factors. Many studies have identified genetic risk factors for these diseases, but concordance rates among monozygotic twins are 25–40%, suggesting that nonheritable environmental factors play a more prominent role.1,2 Through carefully conducted epidemiologic and other…
