Table 6 shows the results of a logistic regression model examining
the college students whose ASSIST-WHO scores suggested
hazardous drug use by gender, age and their interaction. Gender
predicted ASSIST-WHO alcohol and marijuana scores after controlling
for other sociodemographic, academic and administrative
variables. Men were more likely than women to engage in the
hazardous use of alcohol (OR = 2.033; p < 0.001) and marijuana
(OR = 2.015; p < 0.01). Interaction between age and gender
were observed regarding the use of AASs, amphetamines and
opiate analgesics. Whereas men were more likely to engage in
the hazardous use of AASs than women in the same age range,
women older than 34 years were more likely to engage in the
hazardous use of amphetamines than men.
