Objective : To examine the association between scores on IQ tests in childhood and alcohol induced hangovers in middle aged men and women. Design, Setting, and Participants : A cohort of 12 150 people born in Aberdeen (Scotland) who took part in a school based survey in 1962 when IQ test scores were extracted from educational records. Between 2000 and 2003,7184 (64%) responded to questionnaire inquiries regarding drinking behaviour. Main outcome measures : Self reported hangovers attributable to alcohol consumption on two or more occasions per month. Results : Higher IQ scores at 11 years of age were associated with a lower prevalence of hangovers in middle age (ORper one SD advantage in IQ score ; 95% Cl : 0.80 ; 0.72,0.89). This relation was little affected by adjustment for childhood indicators of socioeconomic position (0.82 ; 0.74,0.91) but was considerably attenuated after control for adult variables (fully adjusted model : 0.89 ; 0.79,1.01). Conclusions : Higher childhood IQ was related to a lower prevalence of alcohol induced hangovers in middle aged men and women. The IQ-hangover effect may at least partially explain the link between early life IQ and adult mortality. This being the first study to examine this relation, more evidence is required.
