Background and objective: The purpose of the present study was to evaluate the effects of a nap at work on the sleepiness of 12-hour, night-shift (registered and assistant) nursing personnel.Methods: Twelve nurses filled out daily logs, the Karolinska Sleepiness Scale (KS), and wore wrist actigraphs for two periods of four continuous days.Results: Mean nap duration during the night shifts was 138.3 (SD+39.8) minutes. The mean sleepiness level assessed by the KS score was lower, 3.3 (SD±1.6), when the nap was taken during the first span (00:01 - 03:00h) of the night shift, compared with 6.6 (SD±1.0) when there was no nap. The mean sleepiness level assessed by the KS score was also lower, 3.6 (SD±0.9), when the nap was taken during the second span (03:01 - 06:00h) of the night shift, compared with 7.0 (SD±1.1) when there was no nap. Thus, napping either during the first or second part of the night shift reduces sleepiness of 12-hour, night-shift nursing personnel. Moreover, the mean duration of the first sleep episode after night work was longer in those who did not nap than in those who did. Conclusions: The results of this study show that napping during the 12-hour, night-shift results in less sleepiness at work and less need for recovery sleep after work

Previous studies have revealed that students who work and study build up sleep deficits during the workweek, which can trigger a sleep rebound during days off. The objective of this study was to investigate the impact of working/non-working on sleepiness during days off among high school students. The study population, aged 14-21 years, attended evening classes in Sao Paulo, Brazil. For the study, the students completed questionnaires on living conditions, health, and work; wore actigraphs; and completed the Karolinska Sleepiness Scale (KSS). To predict sleepiness, a logistic regression analysis was performed. Excessive sleepiness was observed on the first day off among working students. Results suggest that working is a significant predictor for sleepiness and that two shifts of daily systematic activities, study and work, might lead to excessive daytime sleepiness on the first day off. Further, this observed excessive sleepiness may reflect the sleep debt accumulated during the workweek.; Federal Research Agency (CNPq); State of Sao Paulo Research Agency (FAPESP); Karolinska Institutet, Sweden

The double journey (work and study) may result or aggravate health problems, including sleep disturbances, as observed in previous studies with high school students. The aim of this study is to analyze the sleep-wake cycle and perceived sleepiness of working college students during weekdays. Twenty-three healthy college male students, 21-24 years old, working during the day and attending classes in the evening, participated in this study. During five consecutive days, the students filled out daily activities logs and wore actigraphs. Mean sleeping time was lower than 6 hours per night. No significant differences were observed in the sleep-wake cycle during the weekdays. The observed lack of changes in the sleep-wake cycle of these college students might occur as participants were not on a free schedule, but exposed to social constraints, as was the regular attendance to evening college and day work activities. Sleepiness worsened over the evening school hours. Those results show the burden carried by College students who perform double activities - work and study.

Introdução: Trabalhar e estudar têm sido frequentemente observadas entre jovens universitários. Um dos resultados dessa dupla jornada esta população é a restrição aos horários de dormir e acordar, especialmente nos dias de trabalho. Como conseqüência da privação de sono, relatos de sonolência excessiva diurna e queda no desempenho nos estudos e no trabalho são frequentes. Em relação às diferenças entre os sexos, poucos são estudos que abordam as características dos padrões do ciclo vigília-sono e sonolência de universitários trabalhadores, homens e mulheres. Objetivo: Analisar o ciclo vigília-sono e sonolência de homens e mulheres que trabalham e estudam no turno noturno. Metodologia: Participaram deste projeto 82 estudantes universitários trabalhadores, de 21 a 26 anos de idade, que freqüentavam as aulas no período noturno. Na primeira etapa, os participantes preencheram o questionário de caracterização das condições de vida, saúde e trabalho. Na segunda etapa, os participantes utilizaram um actímetro durante 7 dias consecutivos para obtenção de dados de sono e vigília, preencheram a escala de sonolência Karolinska (KSS) e realizaram um teste de vigilância psicomotora (PVT) em diversos momentos do dia. Além disso...

Introdução - Há evidências de que o aumento do consumo de carboidratos esteja associado à sonolência. Quando realizado à noite, o consumo de carboidratos parece ser um fator que afeta o desempenho no trabalho. Paradoxalmente, o trabalho noturno levaria ao aumento da ingestão de alimentos ricos em carboidratos como consequência da privação de sono. Objetivo - Verificar a existência de correlação entre a sonolência e consumo de carboidratos entre motoristas de caminhão. Métodos - Participaram da primeira etapa do estudo 71 motoristas de caminhão com idade média de 41 anos (DP=9,5), divididos em dois grupos: transferência (turno irregular de trabalho) e distribuição (turno diurno). Esta etapa consistiu na aplicação de um questionário com questões sociodemográficas, hábitos de vida, consumo alimentar e questões relacionadas ao trabalho. Na segunda etapa 49 motoristas (24 da transferência com idade média de 41 anos DP=8,3 e 25 da distribuição com idade média de 39 anos DP=11,4) responderam ao recordatório alimentar de 24h em dois dias de trabalho e um de folga, à escala de sonolência de Karolinska (KSS), o protocolo de atividade diária e usaram actimetros por 10 dias consecutivos. Resultados - Cerca de 70 por cento dos motoristas encontravam-se sobrepesos ou obesos. O teste de Kruskal Wallis demonstrou que os motoristas da transferência apresentaram uma média significativamente maior de consumo de carboidratos (91...

The Epworth Sleepiness Scale (ESS) measures daytime sleepiness in adults. This paper reports the following data in 616 medical students: 1 -ESS scores, 2-its correlation with the declared night sleep time, 3-comparison with ESS values obtained from Australia, 4-comparison of ESS values in a sub-population of 111 students tested early and late 1995. There were 387 males, 185 females and 4 not specified. Age = 20.16±2.23 (SD). ESS score = 10.00 ± 3.69 (SD), declared sleep time = 7.04± 1.03 (SD). ESS scores did not statistically correlate with sleep time. Average ESS score was statistically higher than in the Australian sample. Retesting of the medical students showed an increase in ESS values from March to November 1995. Sleep time difference was non-significant. Higher ESS scores in this sample seem to be related to shorter sleep time, but fatigue effects can not be ruled out.

This report presents an analysis of the complaints of increasing daytime sleepiness as well as a study on their possible effects on the academic performance of medical students at the University of Brasilia. The Epworth Sleepiness Scale was applied to 172 medical students, at the beginning of August 1997 and at the end of November 1997. Academic performance was measured by analyzing the number of SS grades (from 9.0 to 10 over ten) and MM grades (from 5.0 to 6.9) attained in exams at the end of that school period. The results showed that at the beginning of the semester, 68 (39.53%) of these 172 students already presented with excessive daytime sleepiness, and that of the 104 remaining students, 38 (22%) developed daytime sleepiness by the end of the semester. Furthermore, it was observed that the sleepier students did not achieve as well as the others on their final examinations.

The prevalence of excessive daytime sleepiness (EDS) in general population was determined by means of 408 home interviews of adults, in a representative sample of Campo Grande city, Brazil. The random sample was stratified by sex, age and economic social status. EDS was considered in those with indexes 11 or more in the Epworth Sleepiness Scale. Statistics used chi-square, Fisher and Pearson tests; and inferences based on binomial distribution parameters; the significance level was 5% and confidence interval (CI) was 95%. The prevalence of EDS was 18.9% of the general population ( SD=1.9%; CI 15.1% to 22.7%). No significant association was found between EDS and the use of hypnotics, nor with insomnia, body mass index, sex, age, years of schooling, economic social status, marital status, occupation and the use of alternative means to improve sleep. When the sample was separated according to sex, only the male group showed significant association between EDS and actual insomnia (p=0.005).

OBJECTIVE: To evaluate the quality of sleep, shift work, alcohol and psychostimulant drug use, and the prevalence of accidents among truck drivers. METHOD: Data were collected using a demographic questionnaire, the Epworth Sleepiness Scale (ESS) and the Pittsburgh sleep quality index (PSQI). Statistical analysis was conducted using the Student t, chi-square, Pearson and Fisher tests. RESULTS: 43.2% of the drivers drove over 16 h a day, and 2.9% worked shifts. Mean number of sleep hours/day was 5.97±1.47; 23.8% slept 5; 23 subjects snored more than three times a week (11.1%). Mean ESS was 6.56±4.2; 21.7% had a score >10. In the preceding five years, 27 drivers (13.1%) were involved in accidents, 5 of which resulted in injuries and 3 in deaths. CONCLUSION: Results showed a high prevalence of sleep disorders, use of alcohol and psychostimulant drugs, and accidents.

OBJECTIVE: To compare MSLT parameters in two groups of patients with daytime sleepiness, correlated to the occurrence and onset of dreams. METHOD: Patients were submitted to the MSLT between January/1999 and June/2002. Sleep onset latency, REM sleep latency and total sleep time were determined. The occurrence of dreams was inquired following each MSLT series. Patients were classified as narcoleptic (N) or non-narcoleptic (NN). RESULTS: Thirty patients were studied, 12 were classified as narcoleptics (N group; 40%), while the remaining 18 as non-narcoleptic (NN group; 60%). Thirty MSLT were performed, resulting in 146 series. Sleep was detected in 126 series (86%) and dreams in 56 series (44.44%). Mean sleep time in the N group was 16.0±6.3 min, while 10.5±7.5 min in the NN group (p

BACKGROUND & PURPOSE: The association of obstructive sleep apnea syndrome (OSAS) and restless legs syndrome (RLS) has been reported in the literature for many years. Both conditions may be responsible for fatigue and somnolence complaints secondary to nocturnal sleep disruption. The primary concern of this study is to evaluate the outcome of fatigue and daytime sleepiness symptoms at baseline and after continuous positive air pressure (CPAP) treatment in OSAS patients with and without RLS. METHOD: A prospective and comparative study between a group of 13 patients with OSAS and a group of 17 patients with OSAS+RLS. Laboratory blood tests and polysomnography were performed at baseline. The Epworth Sleepiness Scale (ESS) and the Pichot?s questionnaire of fatigue/depression (PIC) were applied before and after 3 months of CPAP treatment. Results were compared. RESULTS: No significant differences were found on PSG and laboratory results at baseline. Both groups had similar ESS and PIC scores at baseline (p=0.73 and 0.08, respectively). After n-CPAP, OSAS+RLS patients showed higher ESS and PIC scores (p=0.017 and 0.03, respectively). CONCLUSIONS: Despite a favorable general response, n-CPAP seemed less effective in treating fatigue and sleepiness in the OSAS+RLS group.

OBJECTIVE: To determine the correlations between excessive daytime sleepiness (EDS), assessed by the Epworth sleepiness scale (ESS), and the multiple sleep latency test (MSLT) and nocturnal sleep architecture features, clinical symptoms of narcolepsy (CSN) and subjective sleep quality (SSQ) in patients with narcolepsy. METHOD: Twenty three untreated patients were studied and compared with a matched control group. Diagnosis of narcolepsy was carried out employing a clinical interview, a polysomnographic (PSG) record, and an MSLT. RESULTS: Subjective number of awakenings was the SSQ indicator that best correlated with EDS (ESS and MSLT). Regarding clinical features, diurnal tiredness and sleep paralysis correlated with ESS values. Increase in ESS was related with decrease in total sleep time, SWS, and sleep onset latency. On the other hand, increase in MSLT was related with decrease in SWS. CONCLUSION: These data suggest that EDS in patients with narcolepsy could be impaired by disturbed nocturnal sleep.

Sleep disorders are not uncommon and have been widely reported throughout the world. They have a profound impact on industrialized 24-h societies. Consequences of these problems include impaired social and recreational activities, increased human errors, loss of productivity, and elevated risk of accidents. Conditions such as acute and chronic insomnia, sleep loss, excessive sleepiness, shift-work, jet lag, narcolepsy, and sleep apnea warrant public health attention, since residual sleepiness during the day may affect performance of daily activities such as driving a car. Benzodiazepine hypnotics and zopiclone promote sleep, both having residual effects the following day including sleepiness and reduced alertness. In contrast, the non-benzodiazepine hypnotics zolpidem and zaleplon have no significant next-day residual effects when taken as recommended. Research on the effects of wakefulness-promoting drugs on driving ability is limited. Countermeasures for excessive daytime sleepiness have a limited effect. There is a need for a social awareness program to educate the public about the potential consequences of various sleep disorders such as narcolepsy, sleep apnea, shift-work-related sleep loss, and excessive daytime sleepiness in order to reduce the number of sleep-related traffic accidents.

Introduction Approximately 80% of patients with chronic kidney disease complain about sleep disorders, which is a much higher percentage than in the general population. Excessive daytime sleepiness is the third most frequent complaint in these patients, and it is significantly associated with a higher risk of sleep apnea. The aim of this study was to assess the presence of daytime sleepiness in patients with end stage renal disease (ESRD) who were undergoing diurnal hemodialysis. Materials and methods The Epworth Sleepiness Scale (ESS) was applied to patients with ESRD who underwent diurnal hemodialysis in the Centro de Nefrologia da Zona Norte in Sao Paulo, Brazil. Results A total of 168 patients were included in the study. According to the ESS, 31% presented with a mild propensity to sleep, 22% with a moderate propensity, and 17% with a severe propensity. Conclusion Our study concluded that 70% of the sample of patients with ESRD who were undergoing hemodialysis presented with a propensity to sleep in inappropriate circumstances on the ESS. When excessive daytime sleepiness is associated with sleep apnea and other comorbidities, it is essential to carefully assess patients’ complaints.

The aim of this study was to characterize the sleep-wake cycle, daytime sleepiness and sleep quality of high school teachers. Ninety-eight high school teachers participated in this study. They were asked to complete the Health and Sleep, Horne & Ostberg, Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index questionnaires and to keep a 14-day sleep diary. This study showed that high-school teachers wake up on average 1 h 12 min earlier (ANOVA; p < 0.05) and go to bed on average 34 min earlier (ANOVA; p < 0.05) during the week than on the weekend. This results in an average of 42 min less time in bed (ANOVA; p < 0.05) on weekdays and characterizes partial sleep deprivation. Moreover, 46% and 51% of teachers were diagnosed with excessive daytime sleepiness and poor sleep quality (?2; p > 0.05), respectively. Therefore, high-school teachers show characteristics of partial sleep deprivation that may contribute to excessive daytime sleepiness and poor sleep quality. This situation may compromise health and quality of life, in addition to teaching performance that can affect the education of their students.

Increasing numbers of overweight children and adults are presenting to sleep medicine clinics for evaluation and treatment of sleepiness. Sleepiness negatively affects quality of life, mental health, productivity, and safety. Thus, it is essential to comprehensively address all potential causes of sleepiness. While many obese individuals presenting with hypersomnolence will be diagnosed with obstructive sleep apnea and their sleepiness will improve with effective therapy for sleep apnea, a significant proportion of patients will continue to have hypersomnolence. Clinical studies demonstrate that obesity without sleep apnea is also associated with a higher prevalence of hypersomnolence and that bariatric surgery can markedly improve hypersomnolence before resolution of obstructive sleep apnea. High fat diet in both humans and animals is associated with hypersomnolence. This review critically examines the relationships between sleepiness, feeding, obesity, and sleep apnea and then discusses the hormonal, metabolic, and inflammatory mechanisms potentially contributing to hypersomnolence in obesity, independent of sleep apnea and other established causes of excessive daytime sleepiness.
