women and 50% of men have had sexual relationships. The average age for the sexual encounter 15,9 ± 1,5 in women and 12,8 ± 3,7 in men. The 77,1% of women and the 84% of men use some method of family planning. Regarding the liquor consumption, the 51,1% of women and the 74% of men consume it. Conclusion: The most important predictable variables for the liquor consumption were the genre (feminine) and having sexual relationships.
