Objective:Poor sleep patterns are common in undergraduates and may turn them prone to
mood disorders, substance abuse and impaired academic performance. The aim
of this study was to assess sleep disturbances among medical students, and
whether associations with academic performance, depressive symptoms or
substance use were present.Methods:Cross-sectional study in which 544 medical students of the Pontificia
Universidad Javeriana in Bogota, Colombia were included. Using a
computer-based survey, self-reported variables were assessed, including
demographics, Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness
Scale (ESS), Berlin Questionnaire, Diagnostic and Statistical Manual
of Mental Disorders (DSM) - IV depression criteria, Grade Point
Average (GPA), and substance use. Associations between these variables were
obtained.Results:Fifty-four percent of students were women. Poor sleep quality (PSQI>5) and
daytime sleepiness (ESS>10) were found in 65% of the population. A higher
GPA was more frequent in students with good sleep quality (OR= 2.6
[1.5-4.5]), lack of daytime sleepiness (OR= 2 [1.3-3.1]) and low risk of
Obstructive Sleep Apnea Syndrome (OSAS) (OR= 3.1 [1.6-5.9]). DSM-IV
depression criteria were fulfilled by 26% of the students and were
associated with poor sleep patterns. Energy drinks use was associated with
poor sleep quality.Discussion:Poor sleep quality, daytime sleepiness and depressive symptoms are frequent
among medical students and are associated with lower academic performance.
The identification of students at risk and the implementation of targeted
interventions are warranted. Fostering adequate sleep habits and training on
sleep medicine may partly counteract these issues.
Objetivo: El cáncer gástrico es la segunda causa de muerte por cáncer y la quinta neoplasia más frecuente en el mundo. En Colombia, es la primera causa de mortalidad por cáncer. La incidencia y mortalidad anuales son 16,3 y 14,2/100.000 habitantes respectivamente. El objetivo de este estudio fue estimar su carga de enfermedad, medida en años de vida ajustados por discapacidad (AVAD), en Colombia.Métodos: Se desarrolló un estudio con enfoque en prevalencia para el año 2014. Para estimar la prevalencia se realizó una búsqueda en los registros del Sistema de Información en Protección Social (SISPRO), y el Departamento Administrativo Nacional de Estadística (DANE). La duración promedio de los casos prevalentes y la sobrevida estimada se obtuvieron de la literatura local. Los AVAD fueron calculados sumando los años de vida perdidos por muerte prematura (AVPM) y los años de vida vividos con discapacidad (AVVD), según metodología de la Organización Mundial de la Salud (OMS).Resultados: las prevalencias estimadas para cinco años en población mayor de 15 años fueron 40,9/100.000 en mujeres y 62,5/100.000 en hombres. El total de AVAD fue 293.418, con una tasa de 623/100.000 habitantes; 97,4% corresponden a AVPM. La tasa de AVVD y AVPM para Colombia fue 16 y 607/100.000, respectivamente.Conclusiones: los datos obtenidos de SISPRO y el DANE estiman una alta carga de enfermedad en Colombia. Es necesaria la implementación de estrategias de detección temprana del cáncer para disminuir la carga de la enfermedad y mejorar el pronóstico de los pacientes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
