TUESDAY, Aug. 17 (HealthDay News) -- Women who drink regular beer may be increasing their risk of developing psoriasis, an autoimmune disorder affecting the skin, new findings suggest.
Other options, such as light beer and wine, were not linked to such a risk.
Researchers from Brigham and Women's Hospital, Harvard Medical School, and Boston University tracked 82,869 women who had not initially been diagnosed with psoriasis for about 15 years, from 1991 through 2005. The participants, from the Nurses' Health Study II, reported their own alcohol consumption and also, over the course of the study, reported whether a doctor had diagnosed psoriasis.
The researchers found that even relatively moderate amounts of beer seemed to increase the risk of psoriasis, with 2.3 drinks a week driving up the risk almost 80 percent.
And five beers a week more than doubled the risk of being diagnosed with this skin condition, as compared with teetotalers.
"We can say that if a woman would like to consume alcohol and if she has a family history of psoriasis or known psoriasis in the past or some other reason she might be predisposed to psoriasis, the alcohol of choice probably should not be nonlight beer," said Dr. Abrar A. Qureshi, lead author of the article appearing in the December issue of Archives of Dermatology.
But Bruce Bebo, director of research and medical programs at the National Psoriasis Foundation, feels the findings "need more investigation to determine whether there's a real connection or not."
And on the question of drinking in general, he added, "from the point of view of the health-care provider, trying to limit alcohol consumption for lots of reasons is important. If this encourages people to limit alcohol consumption, I think that's a positive outcome, but I don't think the National Psoriasis Foundation or any physician group would make a recom
