Alcohol intake was significantly associated with an increased risk of rosacea in women, according to a recent study that included 82,737 women from the Nurses' Health Study II (1991-2005). Information on alcohol intake was collected every 4 years during follow-up. Information on history of clinician-diagnosed rosacea and year of diagnosis was collected in 2005. They found:

• 4,945 cases of rosacea were identified during 14 years of follow-up.
• Compared with never drinkers, increased alcohol intake was associated with a significantly increased risk of rosacea.
• The multivariate-adjusted hazard ratios (HRs) and confidence intervals (CIs) were 1.12 for alcohol intake of 1-4 g/day and 1.53 for ≥30 g/day.
• The associations remained consistent across categories of smoking status.
• Further examination of types of alcoholic beverage consumed revealed that white wine and liquor intake were significantly associated with a higher risk of rosacea.
