Drinking coffee (high intake) was associated with lower risk of developing rosacea, a longitudinal, observational study among women found. The inverse relationship between caffeine and rosacea added up to a 24% lower risk for the highest quintile of consumption compared with the lowest, reported Suyun Li, PhD, of Brown University in Providence, and colleagues in JAMA Dermatology. In their article, Li et al report an inverse association between caffeine intake, particularly from coffee, and risk of incident rosacea. In this longitudinal cohort study of more than 82,000 participants with more than 1.1 million person-years of follow up, higher caffeine intake was associated with lower rosacea risk after adjustment for several confounders. Overall, participants who drank 4 cups of coffee per day were less likely to develop rosacea compared with participants who did not drink coffee. A dose-response association was found for both increasing caffeine and coffee intake. The authors hypothesized that caffeine’s vasoconstrictive and immune suppressive effects might decrease the risk of rosacea.
