Study: Lower IQ Linked to More Heavy Drinking For Males

A study of Swedish military men between 1969 and 1971 revealed a correlation between low IQ scores and men’s frequency of heavy drinking.

Swedish researchers released a study that found men with lower IQs were more likely to drink heavily.

The study, published in the journal Alcoholism: Clinical & Experimental Research, found that young men’s risk of heavy drinking increases 20% for every rung down the IQ ladder the researchers created, according to CBS News.

Researchers studied 50,000 Swedish men between the ages of 18 and 21 who were in the military between 1969 and 1971. The men’s military service provided researchers with IQ scores and drinking habits

The authors of the study warned that many other factors should be taken into account, and previous studies had turned up no conclusive data.
