Objectives 
Internet can accelerate information exchange. Social networks are the most accessed especially Facebook. This kind of networks might create dependency with several negative consequences in people’s life. The aim of this study was to assess potential association between Facebook dependence and poor sleep quality.


Methodology/Principal Findings 
A cross sectional study was performed enrolling undergraduate students of the Universidad Peruana de Ciencias Aplicadas, Lima, Peru. The Internet Addiction Questionnaire, adapted to the Facebook case, and the Pittsburgh Sleep Quality Index, were used. A global score of 6 or greater was defined as the cutoff to determine poor sleep quality. Generalized linear model were used to determine prevalence ratios (PR) and 95% confidence intervals (95%CI). A total of 418 students were analyzed; of them, 322 (77.0%) were women, with a mean age of 20.1 (SD: 2.5) years. Facebook dependence was found in 8.6% (95% CI: 5.9%–11.3%), whereas poor sleep quality was present in 55.0% (95% CI: 50.2%–59.8%). A significant association between Facebook dependence and poor sleep quality mainly explained by daytime dysfunction was found (PR = 1.31; IC95%: 1.04–1.67) after adjusting for age, sex and years in the faculty.


Conclusions 
There is a relationship between Facebook dependence and poor quality of sleep. More than half of students reported poor sleep quality. Strategies to moderate the use of this social network and to improve sleep quality in this population are needed.

Association between Facebook Dependence and Poor Sleep Quality: A Study in a Sample of Undergraduate Students in Peru

Evaluation of depressive symptoms and sleep alterations in college students.

The purpose of this study was to describe behaviors that form part of the life-style of young college students in 10 dimensions: exercise and physical activity, leisure time, self-care and medical care, diet, alcohol, tobacco and illegal drug consumption, sleep, sexuality, interpersonal relationships, coping and perceived emotional state, and their satisfaction with each. 598 students participated (44.7% men and 55.3% women) from a private university in the southwest of Colombia, who answered the College Youth Lifestyle Questionnaire (Cevju). The results show a high prevalence of healthy practices in all dimensions, except for exercise and physical activity, and satisfaction with lifestyle and general health

The Delivery of Behavioral Sleep Medicine to College Students

Purpose Poor quality of sleep and excessive daytime sleepiness affect cognitive ability and have a negative impact on the academic performance of medical students This study aims to determine the prevalence of excessive daytime sleepiness, sleep quality and psychological distress as well as assess their association with low academic performance in this population Participants and methods A cross-sectional study was conducted among 457 medical students from the Faculty of Medicine and Pharmacy of Rabat, Morocco, who completed the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the Epworth Sleepiness Scale to determine the quality of sleep and excessive daytime sleepiness, respectively Sociodemographic variables and psychological distress (Kessler Psychological Distress Scale) were also measured Multivariate linear regression was performed in order to evaluate the link between low academic performance and sleep quality after adjusting for other covariates Results Among the included students, the median age was 20 (19; 21) years; 707% of the participants were females Almost one-third of the students (366%) had excessive daytime sleepiness and this was more frequently observed in female students (43% vs 201%, <0001) Furthermore, 582% of the students were poor sleepers (PSQI ≥5), while 864% of them had psychological distress The bivariate analysis showed that psychological distress was associated with decreased risk of low performance (s=004; 95% CI=0005-007; P=0024) Being a poor sleeper was statistically associated with poor academic performance (s= -007; 95% CI=-014 to -0002; P=004) in the multivariate analysis In our study, daytime sleepiness was not statistically associated with academic performance Conclusion A poor sleep quality determined by PSQI ≥5 was related to poor academic achievement at the end of the study year in medical students

Relationship between poor quality sleep, excessive daytime sleepiness and low academic performance in medical students.

Los trastornos del sueno constituyen uno de los problemas de salud mas relevantes en las sociedades occidentales. La importancia de una buena calidad de sueno no solamente es fundamental como factor determinante de la salud, sino como elemento propiciador de una buena calidad de vida. La calidad del sueno no se refiere unicamente al hecho de dormir bien durante la noche, sino que tambien incluye un buen funcionamiento diurno (un adecuado nivel de atencion para realizar diferentes tareas). Ello hace que sea fundamental estudiar la incidencia de estos trastornos en distintos tipos de poblaciones, asi como los factores que los determinan. Para alcanzar este objetivo, y ante las dificultades que implica la evaluacion polisomnografica en la deteccion de la calidad de sueno, en la mayoria de los casos se opta por el uso de instrumentos de autoinforme, entre los que destaca el Indice de Calidad del Sueno de Pittsburg. Desde la evaluacion conductual consideramos que el sueno esta determinado por cuatro diferentes dimensiones: tiempo circadiano, esto es, la hora del dia en que se localiza, factores intrinsecos del organismo (edad, sueno, patrones de sueno), conductas facilitadoras e inhibidoras realizadas por el sujeto y el ambiente en que duerme. La higiene del sueno incide sobre estas dos ultimas dimensiones, y en nuestro estudio nos centraremos en las conductas inhibidoras (consumo de sustancias psicoactivas). En el estudio se analiza la calidad subjetiva del sueno en una muestra de 716 estudiantes universitarios (584 mujeres y 132 varones) por medio del Indice de Calidad del Sueno de Pittsburg, y se evaluan los efectos del consumo de alcohol, cafeina y tabaco sobre la calidad del sueno. El Indice de Calidad del Sueno de Pittsburg proporciona una puntuacion global de la calidad del sueno y puntuaciones parciales en siete componentes distintos: calidad subjetiva del sueno, latencia del sueno, duracion del sueno, eficiencia habitual del sueno, alteraciones del sueno, uso de medicacion hipnotica y disfuncion diurna. Los resultados encontrados muestran que aproximadamente 30% de la muestra presenta una mala calidad del sueno, una excesiva latencia y una pobre eficiencia del sueno; no se encontraron diferencias entre hombres y mujeres en ningun componente, a excepcion del consumo de hipnoticos, donde las mujeres presentan una mayor puntuacion. Ello parece indicar que las dificultades para iniciar el sueno constituyen una caracteristica de la mala calidad del sueno en los sujetos mas jovenes, mientras que en las personas mayores lo caracteristico son los despertares nocturnos y el despertar precoz. La falta de diferencias en la calidad del sueno entre hombres y mujeres se puede deber a la edad de la muestra (20.92 anos), pues en las mujeres la menor calidad del sueno se hace mas evidente a medida que avanza la edad. Si tenemos en cuenta la puntuacion total del Indice de Calidad del Sueno de Pittsburg, encontramos que 60.33% de la muestra supera la puntuacion de cinco, por lo que estos sujetos pueden ser definidos como malos dormidores. Por otro lado, esta claramente demostrado que el uso excesivo de alcohol, cafeina y nicotina provoca alteraciones del sueno: aumento de la latencia, despertares nocturnos, reduccion del sueno de ondas lentas, reduccion del tiempo total de sueno y pobre calidad autoinformada del sueno. Sin embargo, el efecto que tiene el consumo social (consumo no excesivo) de estas sustancias sobre el sueno es menos conocido. En este estudio hemos definido como consumidores sociales a los sujetos que ingieren entre dos y cuatro copas de alcohol, dos y cuatro tazas de cafe y fuman entre 20 y 30 cigarrillos diariamente. Encontramos que el consumo diario habitual no excesivo de alcohol, cafeina y tabaco, provoca una mala calidad del sueno, una mayor latencia , un mayor numero de perturbaciones y una mayor disfuncion diurna. Esto pone de manifiesto la necesidad de controlar el consumo de estas sustancias para mantener una correcta calidad del sueno.
