Em86 voluntários, as seguintes variáveis foram avaliadas: QS (pelo Índice de Qualidade do Sono de Pittsburgh, ESE (pelaEscala de Sonolência de Epworth) e a AF (pelo aplicativo Google Fit®).Utilizou-se o teste de correlação de Pearson ou teste de correlação de Spearman. A análise de regressão linear simples foi realizada entre as variáveis que apresentaram correlação. Consideraram-se significantes os valores de p<0,05. Houve correlação entre a SDE e a contagem de passos, bem como entre a SDE e a AF. Verificou-se associação entre a SDE e a AF, mas não entre a QS e a AF.

To determine the association between sleep quality (SQ), excessive daytime sleepiness (EDS) and physical activity (PA) in amateur street runners during the COVID-19pandemic. Eighty-six volunteers were evaluated, and the analyzed variables were: SQ (By Pittsburgh Sleep Quality Index), EDS (By Epworth Sleepiness Scale), and PA (By the Google Fit® app). The data was collected remotely, via email, using Google Forms. Pearson correlation test or Spearman correlation test was used for data correlation. Simple linear regression analysis was performed between variables that showed correlation. P values < 0.05 were considered significant. There was a correlation between EDS and step count [r (p) = 0.219 (0.042)], and only an association between PA and EDS was observed. Based on the results, an association was found between EDS and PA. However, no association was found between SQ and PA.

A nationwide study on sleep complaints and associated factors in older adults: ELSI-Brazil / Estudo nacional sobre queixas de sono e fatores associados em idosos: ELSI-Brasil / Estudio nacional sobre quejas de sueño y factores asociados en adultos mayores: ELSI-Brasil

Abstract: Sleep problems, such as difficulty falling asleep, staying asleep, early awakening with failure to continue sleep, and altered sleep-wake cycle, are common in the general population. This cross-sectional study with 6,929 older adults (≥ 60 years) aimed to estimate the prevalence of different types of sleep problems, their associated factors, and the population-attributable fraction of associated factors among older adults. The outcome variables consisted of self-reported sleep problems: insomnia (initial, intermediate, late, and any type of insomnia), poor sleep quality, and daytime sleepiness. The independent variables were sociodemographic and behavioral characteristics and health conditions. The prevalence proportions were initial insomnia (49.1%), intermediate insomnia (49.2%), late insomnia (45.9%), any type of insomnia (58.6%), poor sleep quality (15.6%), and daytime sleepiness (38.4%). Female sex, presence of two or more chronic diseases, not eating the recommended amount of fruits and vegetables, and regular and bad/very bad self-rated health were positively associated with the sleep problems investigated. Consuming alcohol once a month or more was inversely associated with initial insomnia. Population attributable fraction estimates ranged from 3% to 19% considering two or more chronic diseases, not eating the recommended amount of fruits and vegetables, and regular and bad/very bad self-rated health. High prevalence of self-reported sleep problems was evinced in older adults. These results can be useful to guide public health services in the creation of informational, evaluative, and screening strategies for sleep problems in older Brazilian adults.

Resumo: Problemas de sono, como dificuldade para adormecer, permanecer dormindo, despertar precoce com falha na continuidade do sono e alteração do ciclo vigília-sono, são comuns na população em geral. Este estudo transversal com 6.929 idosos (≥ 60 anos) buscou estimar a prevalência de diferentes tipos de problemas de sono, seus fatores associados e a fração atribuível populacional de fatores associados a problemas de sono nessa população. As variáveis de desfecho foram problemas de sono autorreferidos: insônia (inicial, intermediária, tardia e qualquer tipo de insônia), má qualidade do sono e sonolência diurna. As variáveis independentes incluíram características sociodemográficas, comportamentais e condições de saúde. As proporções de prevalência foram: insônia inicial (49,1%), insônia intermediária (49,2%), insônia tardia (45,9%), qualquer tipo de insônia (58,6%), má qualidade do sono (15,6%) e sonolência diurna (38,4%). Sexo feminino, presença de duas ou mais doenças crônicas, não consumir a quantidade recomendada de frutas e hortaliças e autoavaliação da saúde como regular e ruim/muito ruim mostraram associação positiva aos problemas de sono investigados. Consumo de álcool uma vez por mês ou mais associou-se inversamente à insônia inicial. As estimativas da fração atribuível populacional variaram de 3% a 19% considerando duas ou mais doenças crônicas, consumo insuficiente de frutas e vegetais e saúde autorrelatada regular/ruim/muito ruim. Evidenciou-se alta prevalência de problemas de sono autorreferidos em idosos. Esses resultados podem orientar os serviços públicos de saúde na criação de estratégias informativas, avaliativas e de rastreamento de problemas de sono em idosos brasileiros.

Sleep characteristics and excessive daytime sleepiness in adolescents and adults: results from the birth cohorts of three Brazilian cities — RPS Consortium / Características do sono e sonolência diurna excessiva em adolescentes e adultos: resultados das coortes de nascimento de três cidades brasileiras - Consórcio RPS

ABSTRACT Objective: To describe the prevalence of insufficient sleep duration, long sleep latency, terminal or maintenance insomnia, subjective sleep quality, and excessive daytime sleepiness among participants of birth cohorts conducted in three Brazilian cities, and to evaluate differences in prevalence rates within cohorts according to sociodemographic characteristics. Methods: Cross-sectional analyses involving adolescents and adults participating in four birth cohorts conducted in Ribeirão Preto (RP78 and RP94), Pelotas (PEL93) and São Luís (SL97/98). Sleep duration, latency, terminal or maintenance insomnia, and subjective sleep quality were obtained through the Pittsburgh Sleep Quality Index; and excessive daytime sleepiness was assessed using the Epworth Sleepiness Scale. Differences in the prevalence of the outcomes were analyzed in each cohort according to sociodemographic characteristics (skin color, marital status, socioeconomic status, study and working at the time of the interview) stratified by sex. Results: Insufficient sleep duration was the most common outcome at the four cohorts, with higher frequency among men. Long latency was more frequently reported by young adult women in RP94 and PEL93 cohorts, and insomnia by women of the four cohorts, when compared to men of the same age. Women generally suffered more from excessive daytime sleepiness and evaluated the quality of their sleep more negatively than men. In addition to sex, being a student and working were associated with the largest number of outcomes in both sexes. Conclusion: Sleep disorders are more prevalent in women, reinforcing the need for greater investment in sleep health in Brazil, without disregarding gender and socioeconomic determinants.

RESUMO Objetivo: Descrever a prevalência de duração do sono, latência, insônia terminal, qualidade subjetiva do sono e sonolência diurna excessiva entre participantes de coortes de nascimentos realizadas em três cidades brasileiras, bem como avaliar as diferenças nas taxas de prevalência das coortes de acordo com características sociodemográficas. Métodos: Análises transversais envolvendo participantes de quatro coortes de nascimento realizadas em Ribeirão Preto (RP78 e RP94), Pelotas (PEL93) e São Luís (SL97). A duração, a latência, a insônia terminal e a qualidade subjetiva do sono foram obtidas por meio do Índice de Qualidade do Sono de Pittsburgh; e a sonolência diurna excessiva foi avaliada pela Escala de Sonolência de Epworth. As diferenças na prevalência dos desfechos foram analisadas em cada coorte segundo características sociodemográficas estratificadas por sexo. Resultados: A duração insuficiente do sono foi o desfecho mais comum nas quatro coortes, com maior frequência entre os homens. Latência longa foi mais frequentemente relatada por mulheres adultas jovens nas coortes RP94 e PEL93, e insônia por mulheres das quatro coortes, quando comparadas a homens da mesma idade. As mulheres geralmente sofriam mais com sonolência diurna excessiva e avaliavam a qualidade do sono de forma mais negativa do que os homens. Além do sexo, ser estudante e trabalhar estiveram associados ao maior número de desfechos em ambos os sexos. Conclusão: Os distúrbios do sono são mais prevalentes em mulheres, reforçando a necessidade de maior investimento na saúde do sono no Brasil, sem desconsiderar gênero e determinantes socioeconômicos.

Prevalence of Overlap Syndrome in Patients with Obstructive Sleep Apnea in a Quaternary Care Center of Kerala

Background: The coexistence of obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) is termed “Overlap syndrome (OS).” Objectives: The present study aimed at estimating the prevalence of OS among patients diagnosed with OSA. Methods: It was a prospective observational study conducted on patients presenting to respiratory medicine outpatient department (sleep clinic) with symptoms of sleep-disordered breathing and was found to have OSA by overnight polysomnography. These patients were then subjected to spirometry to diagnose COPD. Results: The prevalence of OS in the study population was found to be 41.3%. Excessive daytime sleepiness was found to be higher in overlap group patients (P = 0.033), the difference was statistically significant. The mean age (59.9 ± 9.6 years) was found to be high in the OS group compared to those without the same. The mean forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and FEV1/FVC (pre? and postbronchodilator) spirometry parameters were found to be lower in patients with OS. Conclusion: The study showed that the prevalence of OS in the present study was 41.3%. Excessive daytime sleepiness and age >60 years were risk factors for OS in a patient with OSA. OS patients had lower pulmonary function values.

Association of excessive daytime sleepiness and freezing of gait in Parkinson′s disease / 中华神经科杂志

Objective:To investigate the relationship between excessive daytime sleepiness and freezing of gait in Parkinson′s disease (PD).Methods:A total of 136 participants with PD were consecutively recruited between August 2017 and January 2018 at the Department of Neurology, Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. The patients were divided into freezers with 50 patients and nonfreezers with 86 patients. The clinical characteristics of freezers and nonfreezers in PD patients were assessed. In the longitudinal study, a cohort of nonfreezers with 86 patients at baseline clinical visit for a maximum of 18 months were prospectively followed. The patients were divided into the excessive daytime sleepiness group ( n=14) and the non-excessive daytime sleepiness group ( n=72). Then a Cox regression analysis was performed to further investigate the relationship between excessive daytime sleepiness and freezing of gait in PD, and explore risk factors for freezing of gait. Results:The freezers had significantly worse sleep compared with the nonfreezers. The proportion of patients with excessive daytime sleepiness in freezers was higher than nonfreezers [40% (20/50) vs 16% (14/86), χ2=9.49, P=0.002]. The proportion of freezers in the patients with excessive daytime sleepiness was significantly higher than that in the patients without excessive daytime sleepiness [59% (20/34) vs 29% (30/102), χ2 =9.49, P=0.002]. During a maximum of 18-month follow-up, freezing of gait incidence (6/7) in the excessive daytime sleepiness group was significantly higher than that in the non-excessive daytime sleepiness group [21% (8/39) , χ2 =9.04, P=0.003]. Excessive daytime sleepiness ( HR=8.03, 95% CI 2.58-24.99, P<0.01) and high L-dopa equivalent daily dose ( HR=5.92, 95% CI 1.95-17.93, P=0.002) were significantly associated with an increased hazard of freezing of gait. Conclusion:Excessive daytime sleepiness and high L-dopa equivalent daily dose may be risk factors for the development of freezing of gait in PD in the future.

Common risk factors for daytime sleepiness and hypertension in patients with obstructive sleep apnea syndrome / 中华健康管理学杂志

Objectives:To investigate the common risk factors for excess daytime sleepiness (EDS) and hypertension in obstructive sleep apnea-hypopnea syndrome(OSAHS) patients.Methods:Between January 2020 and February 2021, a total of 103 OSAHS patients diagnosed in the Department of Sleep Medicine Center, the Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University were enrolled as the study population. During polysomnography (PSG) monitoring, noninvasive continuous blood pressure (BP) and heart rate variability (HRV) were monitored simultaneously. Low/high frequency components (LF/HF) were used to reflect sympathetic-vagal balance in frequency domain analysis. According to Epworth Sleepiness Scale (ESS) and BP levels, patients were divided into four groups: simple OSAHS group (ESS<10 scores and BP<140/90 mmHg, n=30)(1 mmHg=0.133 kPa), OSAHS+hypertension group (ESS<10 scores and BP≥140/90 mmHg, n=23), OSAHS+EDS group (ESS≥10 scores and BP<140/90 mmHg, n=26) and OSAHS+hypertension+EDS group (ESS≥10scores and BP≥140/90 mmHg, n=24). The clinical and PSG parameters were analyzed and compared among the four groups. Regression analyses were used to explore the common causative factors for EDS and hypertension. Results:The LF/HF in OSAHS+hypertension+EDS group was significantly higher than the other three groups [3.2% (2.6%, 4.2%) vs 1.4% (1.2%, 1.6%), 2.2% (1.8%, 2.9%), 2.5% (1.6%, 3.1%), all P<0.05]. No difference was observed between OSAHS+hypertension group and OSAHS+EDS group ( P=0.779), but both higher than simple OSAHS group. The linear regression equation showed that LF/HF was most correlated with the percentage of sleep time with oxygen saturation<90% (T90) as compared to the other parameters of sleep disordered breathing (β=0.201, P=0.006). In addition, Pearson correlation analysis showed that LF/HF was significantly correlated with ESS scores and asleep BP levels ( r=0.536, r=0.456, all P<0.05). The logical regression equation showed that LF/HF was a causative risk factor for both EDS and hypertension in OSAHS (β=0.164, 95% CI: 1.018-1.364, P=0.028). Conclusion:The sympathetic-vagal imbalance is a common risk factor for EDS and hypertension in OSAHS patients

Relación entre Apoyo Social percibido, Severidad de Insomnio y Somnolencia Diurna en Adultos Mayores / Relationship between perceived Social Support, Severity of Insomnia and Daytime Sleepiness in Elderly

El apoyo social es un importante factor protector de la salud de los adultos mayores (AM). Asimismo, un buen dormir es fundamental para su bienestar y funcionalidad, siendo las alteraciones del sueño un importante problema de salud pública en este grupo etario. El objetivo del estudio fue determinar la relación entre apoyo social percibido, insomnio y somnolencia diurna en AM residentes en Chillán, Chile. Se realizó un estudio cuantitativo, no experimental, correlacional, de corte transversal. Se aplicó la versión chilena de la Escala de Apoyo Social Percibido (MOS), el Índice de severidad del insomnio (ISI), y la Escala de somnolencia diurna de Epworth a AM pertenecientes a agrupaciones comunitarias. Se entrevistaron a 202 AM de ambos sexos, de edad 72,3±6,2 años. Se presentaron correlaciones positivas entre escolaridad y severidad del insomnio (p<0,05) y entre severidad del insomnio y somnolencia (p<0,001), además, se encontraron correlaciones negativas entre severidad del insomnio y apoyo social percibido, tanto en forma global como por dimensiones (p<0,05). La dimensión "Interacción social positiva" se correlacionó también de forma negativa con la somnolencia diurna. Los AM participantes del estudio que presentaron un alto nivel de apoyo social presentaron una menor prevalencia y severidad del insomnio

Social support is an important protective factor for the health of elderly (E).Likewise, good sleep is fundamental for their well-being and functionality, being sleep disorder an important public health problem in this age group. The objective of this study was to determine the relationship between perceived social support, insomnia and daytime sleepiness in elderly residents of Chillán, Chile. A quantitative, non-experimental, correlational, cross-sectional study was carried out. The Chilean version of the Perceived Social Support Scale (MOS), the Index of severity of insomnia (ISI) and the Daytime Sleepiness Scale of Epworth was applied to elderly belonging to community groups. Two hundred two elderly of both sexes were interviewed, age 72.3 ± 6.2 years. There were positive correlations between schooling and severity of insomnia (p <0.05) and between severity of insomnia and somnolence (p< 0.001). In addition, there were negative correlations between severity of insomnia and perceived social support, both globally and by dimensions (p <0.05). The dimension "Positive social interaction" also correlates negatively with daytime sleepiness. The elderly participants of the study who presented a high level of social support had a lower prevalence and severity of insomnia

Utility of the Epworth sleepiness scale: Hindi version in identifying obstructive sleep apnoea in adult patients with symptoms of sleep disordered breathing in a tertiary care centre

Background: Excessive daytime sleepiness is a key symptom in patients with sleep- breathing disorders (SBD) and represents a new major public health issue due to its repercussions. The ESS is a simple and validated method, which measures the probability of falling asleep in a variety of situations. Aims and objectives is to study the accuracy of the Epworth Sleepiness Scale (ESS) questionnaire in the identification of Obstructive Sleep Apnoea (OSA) in patients with symptoms of sleep disordered breathing in a tertiary care centre.Methods: This present study was conducted in the Department of Respiratory medicine, New Medical College, Kota on 70 adult patients who presented with symptoms of Sleep Disordered Breathing and underwent Type 2 Polysomnography after answering Epworth sleepiness score in Hindi Language.Results: Epworth sleepiness scale has predicted excessive day time sleepiness in 60% of study subjects with ESS score more than 10 taken as cut off. Mean value for ESS in the study was 10.78. 35.71% of the patients had severe OSA diagnosed by polysomnography and 30% patients had moderate OSA. Mild OSA was detected in 7.14% patients. Sensitivity of the ESS score >10 in diagnosing OSA was found to be 72.5%. Specificity of the scale was 73.6%.There was significant correlation between ESS score and diagnosis of OSA (p value <0.001).Conclusions: The study concludes that ESS has got good relevance in predicting OSA in patients with sleep disordered breathing.

Effect of prenap coffee on daytime sleepiness in university students

Background: Daytime sleepiness impairs academic performance in college students. Napping is a counter to daytime sleepiness, but often causes sleep inertia on waking up. Caffeine absorption from beverages peaks 30 minutes after their ingestion presenting a window of opportunity to have a short nap such that the time of waking up is in synchrony with onset of action of caffeine; thereby abolishing post-nap inertia and achieving synergistic mitigation of fatigue.Objective of this study to assess effect of nap, coffee, ‘coffee and nap’ and ‘wakeful break without coffee’ on daytime sleepiness using Psychomotor Vigilance Tests (PVTs) and Karolinska Sleepiness Scale (KSS) score.Methods: After Institutional Review Board clearance, 10 subjects (aged 19-21 years) were selected using their Epworth Sleepiness Scale score (ESS >5) and called to the study site 8 times on different days to be exposed to these four conditions twice - only coffee (standardized), only nap (30min), coffee immediately followed by 30min nap, wakeful break (30min) without coffee or nap. Pre and post scores were recorded for electronic PVT (Reaction Time and Motor Responsiveness) and KSS for each attempt.Results: Test outcome was associated with intervention used (p=0.00001). ‘Nap only’ group was associated with deterioration in outcomes (p=0.00001), accounting for highest percentage (41%) of all deteriorated test outcomes. ‘Coffee only’ group was associated with improvement in test scores (p=0.00001), responsible for highest share (38.8%) of all improved test outcomes. ‘Nap only’ and ‘Coffee-nap’ group showed improvement in 11.67% and 21.67% of outcomes respectively. Conclusions: Pre-nap coffee is a proactive counter-measure to post nap sleep inertia.

Fatores Associados aos Níveis de Fadiga e Sonolência Excessiva Diurna em Estudantes do Internato de um Curso de Medicina / Factors Associated with Levels of Fatigue and Excessive Daytime Sleepiness in Medical Internship Students

Resumo: Introdução: O objetivo deste estudo foi mensurar os níveis de fadiga e SED em estudantes internos de um curso de Medicina, bem como analisar os fatores sociodemográficos e pessoais associados. Métodos: Trata-se de um estudo transversal analítico com abordagem quantitativa. Os participantes da pesquisa foram alunos do internato da PUC Goiás, período que corresponde aos dois últimos anos de curso. Para o desenvolvimento da pesquisa, utilizaram-se três instrumentos: um questionário sociodemográfico com perguntas direcionadas ao fenômeno investigado, a Escala de Sonolência de Epworth (ESE) e a Escala de Fadiga de Chalder. Resultados: Foram incluídos na pesquisa 116 estudantes internos do curso de medicina da PUC Goiás. A média de idade foi de 24,3 (±8,4) anos. Quanto ao sexo, 31,9% da amostra foi composta pelo sexo masculino, e 68,1%, feminino. Quando se analisou o nível de fadiga, observou-se a presença considerável de fadiga em 99 (85,3%) dos internos. Na comparação entre fadiga e os aspectos sociodemográficos, constatou-se que a variável sexo obteve associação significativa, com maiores escores em alunos do sexo feminino (p = 0,035). Já na comparação da fadiga com os aspectos pessoais, observou-se associação significativa da fadiga com os que afirmaram: praticar atividades físicas raramente (p = 0,0038), praticar atividade artística às vezes (p = 0,034), fazer atividade turística às vezes (p = 0,022), ter doença psiquiátrica (p = 0,0006), ter dificuldades para dormir (p < 0,0001), não ser fumante (p = 0,011), fazer uso de substâncias que alteram o sono (p = 0,028) e não estar satisfeito com o próprio rendimento acadêmico (p < 0,0001). Quanto à análise da sonolência excessiva diurna, perceberam-se níveis consideráveis de sonolência em 62 (53,4%) dos estudantes, e o escore médio entre os internos participantes foi de 11,2. Na comparação dos aspectos sociodemográficos dos participantes do estudo com os níveis de SED, identificou-se maior escore no sexo feminino (p = 0,041). Quando se comparou a SED com os aspectos pessoais dos estudantes, observou-se associação significativa entre os alunos que referiram ter dificuldade para dormir (p = 0,039) e aqueles que não estavam satisfeitos com o próprio rendimento acadêmico (p = 0,027). Por fim, a análise de correlação de Pearson foi realizada entre os níveis de fadiga e os níveis de SED dos 116 estudantes internos de medicina pesquisados e identificou com significância estatística uma moderada correlação positiva (r = 0,3779) entre esses dois agravos (p < 0,0001). Conclusão: Os dados apontaram que aspectos sociodemográficos e pessoais dos discentes exercem influência direta sobre os seus níveis de fadiga e SED. Tal evidência é de suma relevância, já que fadiga e SED podem trazer consequências negativas para os acadêmicos. Um melhor conhecimento da associação positiva entre fadiga e SED, bem como os fatores associados a esses agravos, permite uma abordagem dessa problemática por parte das instituições de ensino superior, visando aos melhores desfechos na qualidade de vida dos discentes e futuros profissionais médicos.

Abstract: Introduction: To measure the fatigue and excessive daytime sleepiness (EDS) levels in medical internship students, as well as to analyze associated sociodemographic and personal factors. Methods: This is an analytical cross-sectional study with a quantitative approach. The study participants were medical internship students from PUC Goiás, a period that corresponds to the last two years of the medical course. Three instruments were used for the study development: a sociodemographic questionnaire with questions directed to the investigated phenomenon, the Epworth Sleepiness Scale (ESS) and the Chalder Fatigue Scale. Results: A total of 116 internship students from PUC Goiás medical school were included in the study. The mean age was 24.3 (± 8.4) years. Regarding gender, 31.9% of the sample consisted of males and 68.1% of females. When analyzing the level of fatigue, the considerable presence of fatigue was observed in 99 (85.3%) of the internship students. When comparing fatigue with the sociodemographic aspects of the analyzed students, it was observed that the gender variable showed a significant association, reaching higher scores in female students (p = 0.035). When comparing fatigue with the students' personal aspects a significant association with fatigue was observed among students who stated: rarely practicing physical activities (p = 0.0038); sometimes practicing artistic activities (p = 0.034); sometimes doing tourist activities (p = 0.022), having a psychiatric illness (p = 0.0006); having difficulty sleeping (p <0.0001); not smoking (p = 0.011); using sleep-altering substances (p = 0.028) and not being satisfied with their academic performance (p <0.0001). As for the analysis of EDS, considerable levels of sleepiness were observed in 62 (53.4%) students, and the mean score among the participants was 11.2. When evaluating the sociodemographic aspects of the study participants regarding EDS, it was observed that higher levels were again found in females (p = 0.041). Compared the EDS with the students' personal aspects , a significant association was observed in students who reported having difficulty sleeping (p = 0.039) and students who were not satisfied with their academic performance (p = 0.027). Finally, Pearson's correlation analysis was performed between fatigue levels and EDS levels of the 116 medical internship students analyzed and identified a positive moderate correlation with statistical significance (r = 0.3777) between these two disorders (p <0.0001). Conclusion: Data showed that the students' sociodemographic and personal aspects have a direct influence on their fatigue and EDS levels. Such evidence is of the utmost importance, as fatigue and EDS can have negative consequences for medical students. Having better knowledge about the correlation between these disorders, as well as the factors related to them, allows the approach of this problem by higher education institutions, aiming at better outcomes regarding the quality of life of students and future professionals.

Factores asociados con somnolencia diurna excesiva en estudiantes de Medicina de una institución de educación superior de Bucaramanga / Factors Associated with Excessive Daytime Sleepiness in Medical Students of a Higher Education Institution of Bucaramanga

RESUMEN Introducción: La somnolencia diurna excesiva (SDE) puede llegar a interferir en el desempeño académico y profesional, debido a que las personas afectadas tienden a quedarse dormidas en situaciones que exigen un alto nivel de atención. Los estudiantes de Medicina representan una población en riesgo de SDE, dada la exigencia académica de numerosas horas de estudio, debido al gran número de créditos por asignatura contenidos en el plan de estudios del programa académico, las prácticas docentes asistenciales y los turnos nocturnos, que pueden generar privación o déficit acumulado del sueño. Por esta razón, es importante estimar la prevalencia de SDE y los factores asociados en estudiantes de Medicina de una institución de educación superior (IES) de Bucaramanga, con el objetivo de implementar estrategias de prevención primaria que disminuyan la presentación de este problema y mejoren la calidad de vida y el desempeño académico de los estudiantes. Material y métodos: Estudio transversal analítico observacional, con una muestra poblacional de 458 estudiantes de Medicina matriculados en el segundo semestre de 2015 en la Universidad Autónoma de Bucaramanga (UNAB), quienes respondieron a 4 cuestionarios: variables sociodemográficas, escala de somnolencia de Epworth, índice de calidad del sueño de Pittsburg (ICSP) e índice de higiene del sueño (IHS). Se realizó el análisis bivariable y multivariable en busca de asociación con SDE. Resultados: Los estudiantes tenían una media de edad de 20,3 arios; de los 458 encuestados, el 62,88% eran mujeres. Se estableció que el 80,75% de los participantes tenían SDE y el 80,55%, una percepción negativa de la calidad del sueño (OR = 1,91;IC95%, 1,11-3,29; p = 0,019). En el análisis multivariable, se encontró que el hecho de estar cursando ciencias clínicas disminuye el riesgo de SDE respecto a quienes estaban cursando el ciclo básico. Además, se observó que una puntuación > 15 en el IHS aumenta de manera significativa el riesgo de padecer SDE. Conclusiones: Aunque es frecuente encontrar SDE en los estudiantes de Medicina, solo un pequeño porcentaje de ellos sufren la forma severa de este trastorno del sueño. Estar cursando asignaturas del ciclo básico se asocia con mayor riesgo de SDE, por lo cual es importante que los comités curriculares de las IES evalúen regularmente la cantidad de horas de trabajo supervisado e independiente que realizan los estudiantes de Medicina. Finalmente, es importante emprender campañas orientadas a mejorar la percepción de riesgo sobre el uso de bebidas energizantes de los estudiantes universitarios y realizar, desde el ingreso al programa académico, recomendaciones sobre los hábitos de higiene del sueño.

ABSTRACT Introduction: Excessive daytime sleepiness (EDS) can interfere with academic and professional performance, as affected individuals tend to fall asleep in situations that demand a high level of alertness. Medical students are often a population at risk of suffering from EDS due to the demanding number of study hours, the significant number of credits per subject in the academic curriculum, practical teaching sessions and hospital night shifts, which can lead to sleep deprivation or sleep debt. It is for these reasons that it is important to estimate the prevalence of EDS and its associated factors in medical students of a Higher Education Institution (HEI) in Bucaramanga, in order to implement early prevention strategies to reduce the occurrence of this problem and to improve the students' quality of life and academic performance. Material and methods: An observational, cross-sectional analytical study with a population sample of 458 medical students enrolled in the second semester of 2015 at the Universidad Autonomade Bucaramanga (UNAB), who completed four questionnaires: Sociodemographic Variables, Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index and Sleep Hygiene Index (SHI). A bivariate and multivariate analysis was performed to identify any correlations with EDS. Results: Mean student age was 20.3 years and 62.88% of the 458 respondents were women. We were able to establish that 80.75% of participants suffered from EDS and 80.55% had a negative perception of their sleep quality (OR=1.91; 95% CI, 1.11-3.29; p =0.019). In the multivariate analysis, it was found that the risk of EDS is lower in the clinical sciences than in the basic cycle. Furthermore, it was noted that a score higher than 15 in the Sleep Hygiene Index significantly increases the risk of suffering from EDS. Conclusions: Although EDS is very common in medical students, only a small percentage present the most severe form of this sleep disorder. Being enrolled in basic cycle subjects is associated with a higher risk of suffering EDS, so it is important for the curriculum committees of higher education institutions to regularly evaluate the number of hours of supervised and independent work performed by medical students. Finally, it is important to implement campaigns aimed at improving university students' perception of the risk of taking energy drinks and to establish sleep hygiene recommendations from the start of the academic programme.

A Study on Association between Sleep Habits and Academic Performance among Medical Undergraduates in Maharaja Agrasen Medical College Agroha.

Introduction: Good quality and adequate amount of sleepis necessary for being healthy. Medical students are proneto more stress due to their academic demands. The sleepamong students is characterized by inadequate sleeping hours,delayed sleep onset, and mid day nap. Current research aimedto study sleep habits among medical students and to findrelationship between sleep habits and stress with academicperformance of students.Material and Methods: This cross–sectional study wascarried out among 139 medical students of third semester,seventh semester and interns enrolled at Maharaja AgrasenMedical College, Agroha (Dist. Hisar), Haryana. Primarytool in this study was a predesigned and semi-structuredquestionnaire. Epworth Sleepiness Scale (ESS) was used toassess daytime sleepiness. Collected data was analysed usingfrequencies, percentages and chi square test.Results: Out of 139 students, 38.8% were considered tohave excessive daytime sleepiness (EDS score >10). Femalestudents (43.1%) were found to have more abnormal EDS scoreas compare to male students(35.1%). Out of total, 70 studentssecured marks between 60-70 percent in which maximumnumber of students (61.42%) were stress free during examsand 54% had sleep duration of 7-10 hours. Good health wasfound to be strongly significant with academic performanceof the students. Duration of study hours was found to besignificant with academic performance of students. Delayedsleep onset was found to be more in female students (55%).Mid day nap was found in 76.25% of students.Conclusion: The negative effects of sleep difficulties havebeen well documented. EDS was more in female students.Also, good health had significant association with academicperformance so the knowledge of importance of good qualityand adequate amount of sleep and its impact on health shouldbe emphasized and translated into practice.

Day time sleepiness in medical undergraduates: social media the culprit?

Background: Medical undergraduates have been seen to be suffering from sleep disturbances, especially daytime sleepiness. Social Media usage or social networking has also tremendously increased over the past few years in adolescents. It has also increased in the day-to-day lives of medical students. Authors therefore tried to find out the association, if any, between social Media usage and daytime sleepiness in medical undergraduates and whether daytime sleepiness can affect their academic performance. The objective of the present study was to ascertain the association between daytime sleepiness and usage of social media among medical students and to look for any association of daytime sleepiness with academic performance.Methods: A self-administered, questionnaire-based study was conducted on medical undergraduate students to assess social media usage. Epworth sleepiness score was determined. ‘Analysis of variance’ was done to look for any association between (a) social media usage and daytime sleepiness (b) daytime sleepiness and academic performance.Results: The majority of students (77.14%) used social media for 2-5hours per day and whatsapp was the most commonly used medium by them. Highly significant association was observed between the usage of social media and daytime sleepiness among the medical undergraduates. Daytime sleepiness was also significantly related to the academic performance of the participating students.Conclusions: Sleep disturbance particularly daytime sleepiness is significantly associated with the usage of social media among first year medical undergraduates and can significantly affect their academic performance.

Clinical Analysis of Daytime Sleepiness and Insomnia in Patients with Obstructive Sleep Apnea

BACKGROUND AND OBJECTIVES: Sleep disturbances and excessive daytime sleepiness (EDS) are the major symptoms of obstructive sleep apnea (OSA). This study aimed to investigate clinical implications of insomnia and EDS in patients with OSA using the Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). MATERIALS AND METHOD: We evaluated 131 subjects with suspected OSA who were undergoing polysomnography (PSG) and performing the PSQI and ESS surveys. OSA was diagnosed when the apnea-hypopnea index was five or more. EDS was defined when ESS score was 11 points or higher. Detailed history and questionnaire were used to categorize insomnia. We compared clinical variables and PSG results in subgroups with or without insomnia and EDS. RESULTS: There were no significant differences of PSQI and ESS score between controls and OSA. OSA with insomnia had significantly increased total score (p < 0.001) and decreased total sleep time (p=0.001) and sleep efficiency (p=0.001) on the PSQI compared to those without insomnia. OSA with EDS showed significantly increased PSQI score (p=0.022) and decreased total sleep time (p=0.018) on PSG compared to those without EDS. Neither PSQI nor ESS score had a correlation with respiratory variables such as AHI and oxygen saturation. Total sleep time had a significant effect on both insomnia and EDS in patients with OSA. CONCLUSION: Decreased total sleep time had important effects on subjective symptoms of OSA and comorbid insomnia. Therefore, restoration of decreased sleep time is important in the management of OSA.

Clinical Predictors of Excessive Daytime Sleepiness in Patients with Parkinson's Disease

BACKGROUND AND PURPOSE: Excessive daytime sleepiness (EDS) is a common complaint among patients with Parkinson's disease (PD). Several factors have been associated with EDS in PD, especially neuropsychiatric symptoms. This study aimed to determine the relationships between neuropsychiatric symptoms, sociodemographic and clinical parameters, and EDS in PD. METHODS: This cross-sectional study analyzed 85 patients with PD. All patients underwent socioeconomic and clinical data evaluations followed by a psychiatric interview and a neurological examination, including the assessment of sleep features. Patients were divided into two groups according to the presence or absence of EDS, which was defined as a score higher than 10 on the Epworth Sleepiness Scale. Binary logistic regression was performed in order to describe the predictors of EDS. RESULTS: We found that EDS affects 40% of PD patients and is associated with older age, restless legs syndrome, depressive and anxious symptoms, and worse sleep quality. In the multivariate analysis, older age, levodopa use, and worse sleep quality remained as significant predictors of EDS in PD. CONCLUSIONS: Nighttime sleep problems, older age, and levodopa use are significantly associated with EDS in PD. A careful assessment and the management of sleep problems in PD patients might help to improve their quality of life.
