[Attitudes towards consumption and non-consumption of alcohol among high school students in Mexico].

The objective of this study was to identify differences in high school students' attitudes towards the consumption or non-consumption of alcohol using the theory of planned behavior. This was a qualitative, descriptive, cross-sectional study that included a sample of 131 students. We found that 74% of students had consumed alcohol, and 18.3% exhibited a harmful level of consumption. We also found that behavioral beliefs towards consumption were higher among alcohol consumers (mean=29.32, median=27.50) than those who did not consume alcohol. Moreover, positive beliefs towards consumption were higher among alcohol consumers (mean=17.72, median=9.52) than non-consumers, which demonstrates a need for preventative programs to strengthen adolescents' beliefs concerning alcohol as well as protective factors and healthy lifestyles.
