Objetivos: Determinar el grado de somnolencia diurna y calidad del sueño en estudiantes de medicina. Diseño: Estudio transversal. Lugar: Universidad Peruana Cayetano Heredia. Participantes: Estudiantes de medicina. Intervenciones: Muestra no probabilística de estudiantes de medicina del sexto (76 externos) y sétimo (74 internos) años de estudios. Cuestionarios: datos demográficos, escala de somnolencia de Epworth e índice de calidad del sueño Pittsburgh. Principales medidas de resultados: Somnolencia diurna y calidad del sueño. Resultados: No hubo diferencia con respecto a la somnolencia y calidad del sueño entre externos e internos. De todos los encuestados, 58% tenía mala calidad del sueño y 34% excesiva somnolencia diurna. La latencia subjetiva del sueño mayor de 30 minutos, dormir 6 horas o menos, eficiencia subjetiva del sueño menor de 85% y el uso de medicación hipnótica estuvieron asociados con mala calidad del sueño. Asimismo, dormir 5 horas o menos, consumo de cafeína y tabaquismo estuvieron asociados a mala calidad del sueño y excesiva somnolencia diurna. La correlación entre calidad del sueño y somnolencia diurna fue R=0,426 p<0,001. Conclusiones: Encontramos alta frecuencia de pobre calidad del sueño y excesiva somnolencia diurna en los estudiantes de medicina encuestados. Ambas estuvieron asociadas a consumo de cafeína y tabaco, latencia subjetiva del sueño prolongada, corta duración del sueño, eficiencia subjetiva del sueño menor de 85% y uso de medicación hipnótica. Hubo correlación entre calidad del sueño y somnolencia diurna.

The ESS-VP and ESS-MPV, adapted to adult Peruvian population, are comparable to the original scale, reliable, valid, and change-sensitive. It is proposed that the ESS-MPV should be applied in Peruvian population who do not drive motorized vehicles.

Background. Sleep duration, either short or long, has been associated with diseases such as obesity, type-2 diabetes and cardiovascular diseases. Characterizing the prevalence and patterns of sleep duration at the population-level, especially in resource-constrained settings, will provide informative evidence on a potentially modifiable risk factor. The aim of this study was to explore the patterns of sleep duration in the Peruvian adult and adolescent population, together with its socio-demographic profile.Material and Methods. A total of 12,424 subjects, mean age 35.8 years (SD ±17.7), 50.6% males, were included in the analysis. This is a cross-sectional study, secondary analysis of the Use of Time National Survey conducted in 2010. We used weighted means and proportions to describe sleep duration according to socio-demographic variables (area and region; sex; age; education attainment; asset index; martial and job status). We used Poisson regressions, taking into account the multistage sampling design of the survey, to calculate crude and adjusted prevalence ratios (PR) and 95% confidence intervals (95% CI). Main outcomes were short- (<6 h) and long-sleep duration (≥ 9 h).Results. On average, Peruvians slept 7.7 h (95% CI [7.4–8.0]) on weekdays and 8.0 h (95% CI [7.8–8.1]) during weekends. The proportions of short- and long-sleep, during weekdays, were 4.3% (95% CI [2.9%–6.3%]) and 22.4% (95% CI [14.9%–32.1%]), respectively. Regarding urban and rural areas, a much higher proportion of short-sleep was observed in the former (92.0% vs. 8.0%); both for weekdays and weekends. On the multivariable analysis, compared to regular-sleepers (≥ 6 to <9 h), short-sleepers were twice more likely to be older and to have higher educational status, and 50% more likely to be currently employed. Similarly, relative to regular-sleep, long-sleepers were more likely to have a lower socioeconomic status as per educational attainment.Conclusions. In this nationally representative sample, the sociodemographic profile of short-sleep contrasts the long-sleep. These scenarios in Peru, as depicted by sleeping duration, differ from patterns reported in other high-income settings and could serve as the basis to inform and to improve sleep habits in the population. Moreover, it seems important to address the higher frequency of short-sleep duration found in urban versus rural settings.

Scientific production on OSA is increasing with limited international collaboration. The country with the greatest production in this period (1991-2012) was the USA, which concentrated the international collaboration network on OSA. We recommended that articles should be produced with international collaboration to improve the quantity of scientific publications and their chances of publication in high impact journals.

We report two cases of adult males with sleep-related eating disorder (SRED), with durations of 3 and 7 years, and without associated psychiatric history. In both cases, the use of low-dose (25 mg) sertraline taken at bedtime resulted in immediate, full and sustained resolution of symptoms at the latest follow-ups. The sertraline efficacy was of particular benefit for the patient reported on in case 2 who was a commercial airline pilot subjected to a highly restricted list of Federal Aviation Administration-approved medications. Risk factors for SRED included smoking cessation and work-related stress in case 1, and a history of sleepwalking and work-related circadian disruptions and partial sleep deprivations in case 2. Sertraline therapy of SRED is considered within a review of all current pharmacologic therapies of SRED.

Fatigue, sleepiness, and a history of accident or near accident were frequent. Having had an accident or near accident was significantly associated with nodding while driving and the number of years as a driver in Chiclayo's bus drivers.

The fatigue and sleepiness levels were similar between formal and informal drivers. Companies classified as formal, have a high percentage of informality amongst their drivers.

No association was found between depressive symptoms and OSAH.
