ABSTRACT
OBJETIVO: el objetivo primario es determinar si los estudiantes de medicina de la Universidad Mayor de San Simón (UMSS) sufren de somnolencia diurna excesiva mediante el uso de la Escala de somnolencia de Epworth (ESE). MÉTODOS: Se trata de un estudio transversal, descriptivo. Estudiantes de medicina de la UMSS completaron una encuesta la cual incluía datos demográficos, escala del sueño de Epworth traducida al español, número de horas nocturnas de sueño, siestas y uso de estimulantes del SNC durante el mes anterior a la realización de la encuesta. RESULTADOS: el universo consistió en 1923 estudiantes y la muestra en 324 estudiantes del primer al quinto curso de carrera de medicina (5% margen de error, 95% nivel de confianza); 57% del sexo femenino, media de edad de 21 años (±2,1), la media de la escala de Epworth fue de 9 (±3,3) (95% IC 8,46-9,54); 23,6% presentó algún grado de somnolencia diurna excesiva; 67% de los estudiantes indican dormir 4-6 hrs diarias; 79% goza entre 5 90 minutos de siesta cada día durante el mes anterior a la encuesta; 76% reporta usar algún tipo de estimulante del sistema nervioso central. CONCLUSIONES: un porcentaje menor pero relevante de estudiantes de medicina de la UMSS tiene algún grado de somnolencia diurna excesiva. Este menor porcentaje puede deberse al uso de siestas; habito comúnmente practicado en nuestro país.
OBJECTIVES: the primary objective is to determine if medical students of San Simon University (UMSS) suffer from excessive daytime sleepiness using the Epworth Sleeping Scale (ESS). METHODS: It was a cross-sectional, descriptive study. Medical students of San Simon University responded to a survey which included demographics, Epworth Sleepiness Scale translated to Spanish, number of nighttime hours of sleep, presence of naps and use of any stimulant of the central nervous system during the month prior to the survey. RESULTS: The universe consisted of 1923 students and the sample was 324 students from the first to the fifth course of the medical school of University of San Simon (5% margin of error, 95% level of confidence); 57% female, mean age was 21 years (±2.1), the average Epworth Sleepiness scale was 9 (±3.3) (95% CI 8.46-9.54); 23.6% presented some degree of excessive daytime sleepiness; 67% of students indicated sleep 4-6 hours daily; 79% enjoy 5 - 90 minute daily naps during the month prior to survey; 76% reported using some type of stimulant of the central nervous system. CONCLUSIONS: A small but relevant number of medical students have some degree of excessive daytime sleepiness. This is maybe due to use of naps; a habit commonly used in our country.

Delayed sleep-phase syndrome (DSPS) is characterized by delayed sleep onset against the desired clock time. It often presents with symptoms of sleep-onset insomnia or difficulty in awakening at the desired time. We report the finding of sleep studies after 24 h total sleep deprivation (TSD) in a 28-year-old DSPS male patient. He had characteristics of mild chronic DSPS, which may have been precipitated by his frequent night shift assignments. The TSD improved the patients sleep latency and efficiency but all other sleep variables showed marked differences.

OBJECTIVE: To analyze the influence of nocturnal use of computer and their effect on sleep quality, in a group of adolescents. METHOD: Two middle schools were chosen for the research. The sample consisted of adolescents n=160 (55M; 105F), with ages ranging from 15 to 18 years. Questionnaire about computer use with the objective of obtaining information regarding the time and number of hours of nocturnal computer use, were applied for collection of data. They included the Pittsburgh Sleep Quality Index (PSQI), utilized to quantfy sleep quality; student report cards were used to note student's absences and grades were used. RESULTS: The Multiple Logistic Regression test indicated that nocturnal computer use impairs good sleep (p=0.0062). CONCLUSION: Irregular sleep patterns associated with nightly computer use deteriorate sleep quality.
OBJETIVO: Analisar a influência do uso noturno de computador na qualidade de sono, em um grupo de adolescentes. MÉTODO: Foram escolhidas duas instituições educacionais de ensino médio. A amostra tomada foi composta de adolescentes (n=160), ( 55 M; 105 F ); a faixa etária estudada foi de 15 a 18 anos. Para a coleta de dados aplicou-se: Questionário para uso do computador, com a finalidade de coletar informações sobre o horário e a quantidade de horas do uso do computador durante as noites; índice de Qualidade de Sono de Pittsburgh (IQSP) utilizado para quantificar a qualidade do sono; e os boletins dos alunos por meio dos quais foram recolhidas as faltas e as notas dos alunos. RESULTADOS: Pela Regressão Logística Múltipla, observou-se que o uso do computador é um fator que compromete o dormir bem (p=0,0062). CONCLUSÃO: Padrões irregulares de sono associados ao uso noturno de computador estão associados à deterioração da qualidade do sono.
