Researchers have linked binge drinking to low intelligence.
Scientists at the Karolinska Institutet in Stockholm analysed data from 49,321 Swedish men born between 1949-1951, who had been conscripted in the army between 1969-1971.
After examining IQ tests from their conscriptions and data on their total alcohol use, they found that lower results in IQ tests were associated with higher consumption of
“It may be that a higher IQ results in healthier lifestyle choices,” lead researcher Sara Sjölund said. “I hope that our findings add to the general understanding of drinking behaviours and what factors that may influence them. However, we must be very careful in making any attempt to generalise our results to women, since their level of consumption and patterns of drinking likely differ in comparison with men.”
The full study has been published online in the journal of Alcoholism: Clinical & Experimental Research.
A lower IQ has been linked to greater and riskier drinking among young adult men
