IQ and level of alcohol consumption—findings from a national survey of Swedish conscripts.
Bottom Line: We found an increased OR of 1.20 (1.17 to 1.23) for every step decrease on the stanine scale to be a high consumer versus a light consumer of alcohol.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.

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.
