IQ and level of alcohol consumption—findings from a national survey of Swedish conscripts.

Sjölund S, Hemmingsson T, Allebeck P - Alcohol. Clin. Exp. Res. (2015)

Bottom Line: Adjustment for confounders attenuated the associations.Also, IQ in adolescence was found to be inversely associated with moderate/high alcohol consumption measured in middle age.We found that lower results on IQ tests are associated with higher consumption of alcohol measured in terms of both total alcohol intake and binge drinking in Swedish adolescent men.

fig01: Mean consumption of grams alcohol/wk by IQ test results in stanines.

Mentions: In the sensitivity analysis, we found that the continuous measures of total alcohol intake and IQ test result scores were correlated with −0.07, p-value < 0.001. Further, we found that for each step decrease on the stanine scale, there was an increase of 2.6 g of 100% alcohol/wk. Mean alcohol consumption in g/wk by IQ test results in stanines is shown in Fig.1, which indicates how consumption of alcohol decreases with higher IQ.
