Full strength beer is bad for the skin

The aim of this study was to evaluate the independent association between alcohol consumption and risk of developing psoriasis and to determine if this risk is associated with different types of alcoholic beverages. It consisted of a prospective study of female nurses who were followed up from 1991 to 2005. The study population included 82,869 women who reported amount and type of alcohol intake on biennial questionnaires. Participants with a history of psoriasis prior to 1991 were excluded. There were 1150 cases of incident psoriasis, 1069 of which were used for analysis.

Compared with women who did not drink alcohol, the relative risk (RR) of psoriasis was 1.72 for an alcohol consumption of 2.3 drinks/wk or more. When examined by type of alcoholic beverage, there was an association between psoriasis and nonlight beer intake (RR for greater than or equal to 5 drinks/wk); light beer, red wine, white wine, and liquor were not significantly associated with psoriasis risk. The association with nonlight beer intake became stronger in a subset of confirmed psoriasis cases (RR for greater than or equal to 5 drinks/wk, 2.29).

The researchers concluded:  "Nonlight beer intake is associated with an increased risk of developing psoriasis among women. Other alcoholic beverages did not increase the risk of psoriasis in this study."

I hope the title caught your eye. Perhaps women with psoriasis are ‘driven’ to drink. What about men?
