According to the mean of the total AUDIT score, Ecuadorian and Spanish students had a low risk for alcohol use disorder [99,100]. On the other hand, British and Swedish students reported hazardous drinking [101,102]. In the US, the mean AUDIT score was 5.70, female students obtained a value of 4.86, and their counterparts acquired a value of 7.53, indicating a significant gender difference at the expense of male students [103]. With a focus on problem drinking, students in many European countries are no exception, and evidence again shows that this problem mainly affects male students [87,104]. In terms of socio-economic characteristics, not only gender, but also income plays an important role, while students’ higher incomes can lead to their higher alcohol consumption [104]. Using a univariate analysis, Kumar et al. [105] also confirmed that not only the male gender, but also the level of income is significantly associated with the level of alcohol use measured by the AUDIT diagnostic tool. In response to these findings, alcohol use disorders are also a serious problem that needs to be addressed.
