: The project has the approval of the ethics committee of Universidad Cooperativa de Colombia according to approval number 023–2018, through record N0.001. The principles of the Declaration of Helsinki were applied. Verbal informed consent was obtained. Students consented to the use of the information for investigative purposes, and the analyses were based on data that do not contain information that could lead to the identification of the student. In Colombia, the scientific, technical, and administrative standards for health research are found in the Resolution 8430 of 1993. In it, research is classified as research without risk, with minimal risk, and with risk greater than the minimum. In Article 11 of that resolution, the research we conducted is classified as a risk-free investigation because the study used documentary research techniques and methods, with no intervention or intentional modification of the biological, physiological, psychological, or social variables of the individuals participating in the study. In Article 16, first paragraph of the same resolution, it is stated that in investigations without risk, the investigator can be dispensed from obtaining written informed consent.
