Low IQ Ups Risk Of Heavy Drinking Among Men
Adjustments were made for socio-economic position as a child, psychiatric symptoms and emotional stability and the father's alcohol habits.
"We found that lower results on IQ tests in Swedish adolescent men are associated with a higher consumption of alcohol, measured in both terms of total intake and binge drinking," Sjolund said.
The researchers noted that results may vary among cultures and countries.
"Poor performance on IQ tests tend to go along with other disadvantages, for instance, poorer social background and emotional problems, which may explain the association with risky alcohol consumption," Daniel Falkstedt, assistant professor at Karolinska Institutet said.
"In reality, other differences of importance are likely to exist among the men, which could further explain the IQ-alcohol association," Falkstedt said.
The study is forthcoming in the journal Alcoholism: Clinical and Experimental Research.
