Correlation between cigarette smoking and alcohol consumption and Rosacea

Controversy persists regarding the causal relationship between cigarette smoking, alcohol consumption, and Rosacea. Rosacea, a common skin condition that causes flushing or long-term redness on your face, impacts approximately 5% of the adult population. Researchers used the Mendelian randomization (MR) method to elucidate the correlation between cigarette smoking, alcohol consumption, and Rosacea. They aim is to contribute valuable insights to aid in the prevention and early treatment of Rosacea.
Summary datasets for cigarette smoking parameters (cigarettes smoked per day, smoking status: previous, smoking status: current) and alcohol consumption (alcoholic drinks per week) were selected alongside data for Rosacea from genome-wide association studies (GWAS). The Two-sample MR method was employed to analyse the correlation between cigarette smoking, alcohol consumption, and Rosacea.
The results indicate a significant negative association between cigarettes smoked per day and Rosacea. Moreover, a significant positive correlation was observed between smoking status: previous and Rosacea. However, no significant associations were found between smoking status: current, alcoholic drinks per week, and Rosacea.
The study provides further clarity on the association between cigarette smoking, drinking, and Rosacea through a two-sample MR analysis. Notably, the number of cigarettes smoked per day appears to be associated with a reduced incidence of Rosacea, while cigarette smoking cessation may increase the risk. Surprisingly, alcohol consumption does not emerge as a significant risk factor for Rosacea. These findings contribute to a nuanced understanding of the complex relationship between lifestyle factors and the occurrence of Rosacea, offering potential insights for preventive measures and early intervention.
