HS Incidence Nearly Doubled Among Tobacco Smokers

The incidence of hidradenitis suppurativa (HS) may be doubled in tobacco smokers, according to the results of a recent study.

The relationship between tobacco use and the risk of developing HS is controversial.

Researchers conducted a retrospective cohort analysis using a sample of over 50 million patients, identifying 3,924,310 tobacco smokers, among whom were 7860 patients with HS.

The overall incidence of HS was 0.20% among smokers and 0.11% among non-smokers, and the overall adjusted odds of developing HS was 1.90 among smokers, compared with non-smokers.

Overall, incidence of HS among tobacco smokers was highest in individuals aged 18 to 39 years (0.35%), women (0.28%), African Americans (0.46%) and those with BMI of 30 or more (0.33%).

“Incidence of HS appears to be doubled among tobacco smokers. These findings may support evidence-based counseling efforts on cessation of smoking for populations at risk for HS.”
