Alcohol consumption and the risk of rosacea

Rosacea, a chronic inflammatory skin disease that affects people’s life quality, has been found to be related to many detrimental factors. The association between alcohol consumption and rosacea has long been debated. A systematic review and meta-analysis was conducted to elucidate this association.
Following a systematic search of the literature published before February 16, 2021 on PubMed, Embase, and the Cochrane database. 14 eligible studies were identified, and alcohol consumption was not found to be a risk factor for rosacea. However, there are 4 types of rosacea and in subgroup analysis, alcohol consumption increased the risk of phymatous rosacea (PhR) and the pooled OR was 4.17 (95% CI = 1.76-9.91).
Overall, the study showed that alcohol consumption was a risk factor in phymatous rosacea (PhR), but not the other 3 sub types. More studies of rosacea investigating sex distribution, alcohol intake levels, and types of alcoholic beverages consumed are needed.
