Men and women at risk for alcohol dependence are more likely to choose a mate who also is at risk, say investigators at Washington University School of Medicine in St. Louis. That doesn't necessarily mean, however, that both spouses will end up as problem drinkers.
Alcoholism is more common among partners of alcoholics than among partners of non-alcoholics, but it isn't as common as it might be. The researchers found that in some cases, one spouse's excesses with alcohol actually could help protect the other from alcohol dependence.
A team of researchers from Washington University and from the Queensland Institute of Medical Research in Brisbane, Australia, studied 5,974 twins born between 1902 and 1964 who were part of the Australian Twin Register. They also spoke with 3,814 of those twins' spouses for the study, published in the May issue of the journal Alcoholism: Clinical & Experimental Research.
