Abstract (English): Introduction: The association between sleep and mental health has been observed in the clinical context since individuals with a sleep disorder are more likely to suffer from a mental disorder. Medical students are at high risk in this respect due to the lack of sleep time because of their high workload. Objective: To evaluate a structural equation model predicting the presence of depression through the mediation of anxiety, based on sleep quality in medical students. Method: A quantitative, descriptive, cross-sectional study was conducted with the medical students of the Autonomous University of the State of Quintana Roo from Chetumal, Quintana Roo, Mexico from February to November 2023. Participants completed a questionnaire assessing sociodemographic factors, sleep quality, anxiety, and depression symptoms. Results: Two hundred medical students with an average age of 19.9 years were surveyed to propose a Structural Equation Model, showing that poor sleep quality positively and significantly influences depression, with anxiety serving as a mediator. No direct association was found between poor sleep quality and depression. Discussion and conclusion: A high prevalence of poor sleep quality was observed (75%), surpassing the rates reported in Brazil (68.8%), China (19%), and Lithuania (40%). Moreover, the study showed that women students exhibited higher rates of anxiety and depression. This study underscores the association between sleep quality and mental health, demonstrating that poor sleep quality contributes to increased anxiety and depression among medical students.

Abstract (Spanish): Introducción: La asociación entre el sueño y la salud mental se ha visto en el contexto clínico ya que las personas que presentan algún trastorno del sueño son más propensas a sufrir de algún trastorno mental. Los estudiantes de Medicina son una población en riesgo por el poco tiempo con el que cuentan para dormir. Objetivo: Evaluar un Modelo de Ecuaciones Estructurales que prediga la presencia de depresión mediado por la ansiedad de acuerdo con la calidad del sueño de los estudiantes. Método: Se realizó un estudio cuantitativo, descriptivo y transversal con estudiantes de medicina de la Universidad Autónoma del Estado de Quintana Roo en Chetumal, Quintana Roo, México de febrero a noviembre del 2023. Los estudiantes fueron encuestados sobre factores sociodemográficos, calidad del sueño, así como síntomas de ansiedad y depresión. Resultados: Se encuestaron a 200 estudiantes con un promedio de edad de 19.9 años para proponer un Modelo de Ecuaciones Estructurales el cual demostró que una pobre calidad del sueño afecta positiva y significativamente en la depresión, siendo mediado por la ansiedad. No se encontró una asociación directa entre calidad del sueño y depresión. Discusión y conclusión: Se observó una gran prevalencia de pobre calidad del sueño (75%), superando lo reportado en Brasil (68.8%), China (19%) y Lituania (40%), demostrando a su vez que las mujeres presentan ansiedad y depresión más frecuentemente. Este estudio demuestra que una pobre calidad del sueño contribuye a un incremento en los niveles de ansiedad y depresión de los estudiantes de Medicina. [ABSTRACT FROM AUTHOR]
