Introduction:The objective of this research is to determine the association between family pattern and its influence on the habit of sleep in healthy undergraduates in the Universidad de Ciencias Aplicadas y Ambientales U.D.C.A in Bogotá, D.C. Materials and Methods: It's a descriptive qualitative ethnographic study. The theory of diversity and universality of care proposed by Madeleine Leininger was used, through a semi structured interview; it was applied to a five students, upon application of informed consent, displays obtained by saturation of data. Results and Discussion: The results showed that students must adapt to academic environment, changing sleep habits learned at home, identifying within the most important changes: the environment in relation to rest and change of habits related to the stay up late and academic performance. Conclusions: By implementing the theory proposed by Leininger, it is possible to establish a relationship between sleep habits and customs students learned at home due to family influence generated at the beginning of life, demonstrating its applicability in this research.

Informed consent is a legal document signed by an individual who will undergo an intervention in the health area, or in the research field. This informed consent reflects the individual wellbeing and autonomy and his / her capacity, once he or she has been illustrated in detail about the intervention, to understand its main results and its potential risks of said intervention and his / her willingness to assume it without external pressure. Although this seems trivial, history shows that wellbeing and autonomy have not been considered values in the health area and lesser in research, intentionally or by omission. For the present review, a bibliographic search was carried out in PubMed, Medline, Scielo and Google Scholar databases. The following descriptors were used: history of research, ethics, informed consent, research, nursing and comprehension. We found 2800 articles, in English, Portuguese and Spanish, without time limit. Then after reading abstract of the Articles it was selected 80 articles that were close to the subject and there were used. As a result of the analysis of the information, some guidelines were generated aimed to improve the informed consent process through techniques that improve the explanation by the health professional and the understanding of the participant or patient.

Como se mencionó en el editorial del número anterior, la ciencia y la investigación se comunican a través de artículos científicos o "papers"; sin embargo, el conocimiento científico publicado no es un producto acabado, no es infalible, y es susceptible a errores como lo esbozó el famoso astrofísico y divulgador científico Carl Sagan en dos frases célebres: “La ciencia no es perfecta, con frecuencia se utiliza mal, no es más que una herramienta, pero es la mejor herramienta que tenemos: se corrige a sí misma, está siempre evolucionando y se puede aplicar a todo. Con esta herramienta conquistamos lo imposible” y “en la ciencia la única verdad sagrada es que no hay verdades sagradas” (1). A pesar de las limitaciones planteadas por Sagan, las revistas científicas y los artículos publicados permiten que el progreso científico sea de dominio público y se emplee en beneficio de la sociedad.
