Female (N=21) and male (N=21) college students were asked to estimate their amount of daily alcohol consumption via a modified version of the Drinking Practices Questionnaire. Males reported drinking significantly more alcohol than females. However, when subjects' body weights were used to compare estimated blood alcohol levels (BAC) rather than absolute amount of alcohol consumed, females and males did not differ. This highlights the importance of researchers considering the body weight of their subjects when investigating possible alcohol-related gender biases. When asked to estimate the number of beers needed by a typical young man and a typical young woman to induce moderate and high levels of intoxication, subjects of both genders believed males would require significantly more beer than females to produce both moderate and high levels of intoxication. This pattern remained even when average body weight figures were used to estimate the BAC of the target subjects. This suggests that body weight differences between females and males are unlikely by themselves to account for the gender bias of the subjects. (Author/NB)
