Materials and methods: The present study is of a cross-sectional descriptive observational type, the sample used was 110 students who were studying from the first to the tenth semester, a structured survey was applied and three types of photography were taken, in order to determine the relationship of the forms that it presented. In addition, a univariate (frequencies and percentages) and bivariate analysis was performed through the Chi2 test or Fisher's Exact Test. Results: In the investigation, a greater frequency of the female sex was evidenced in 63.64% (70), 44.55% (49) are in the second semester and 60.00% (66) of the participants are between the ages of 18 to 20 years old.
