Daytime sleepiness in children and adolescents has negative consequences on schoolchildren's daily life and functioning (1-3). Thus it is important to evaluate the prevalence of daytime sleepiness and to find out its predictors. The prevalence of excessive daytime sleepiness in children and adolescents has varied between 0 and 35% in epidemiological studies (4-10). An increase of daytime sleepi...

Daytime sleepiness, or difficulty in maintaining a desired level of wakefulness, is frequently viewed by the general population as a common experience and predictable consequence of insufficient sleep. However, daytime sleepiness can have a serious impact on an individual's health, safety, and quality of life. Despite the fact that population-based studies have found that 1 in 5 adults suffers ...

PURPOSE To identify the best screening measure of daytime sleepiness in adults with heart failure (HF). DATA SOURCES A total of 280 adults with HF completed the Epworth Sleepiness Scale, the Stanford Sleepiness Scale, and a single Likert item measuring daytime sleepiness. The sensitivity and specificity of these self-report measures were assessed in relation to a measure of daytime dysfunctio...

Objectives: The aims of this study were to evaluate patterns of circadian preferences and daytime sleepiness, and to examine the extent to which the consumption of stimulant beverages is associated with daytime sleepiness and evening chronotype among Peruvian college-age students. Methods: A total of 2,581 undergraduate students completed a self-administered comprehensive questionnaire that gat...

BACKGROUND Excessive daytime sleepiness may be determined by a number of factors including personal characteristics, co-morbidities and socio-economic conditions. In this study we identified factors associated with excessive daytime sleepiness in 2 First Nation communities in rural Saskatchewan. METHODS Data for this study were from a 2012-13 baseline assessment of the First Nations Lung Heal...

The present cross-sectional study aimed to assess daytime sleepiness in Chinese adolescents using the Paediatric Daytime Sleepiness Scale (PDSS) and to identify associations between PDSS answers and craniofacial characteristics. A group of 265 Chinese adolescents aged 11-17 years self-completed the PDSS, and their extra- and intra-oral craniofacial characteristics were recorded. Among the parti...

BACKGROUND Obstructive sleep apnoea (OSA) is a condition leading to excessive daytime sleepiness. The aim of the study was a) to study course of daytime sleepiness in patients with OSA and b) to find the most important nocturnal polysomnography parameters influencing daytime sleepiness in OSA. METHODS The cohort consisted of forty-five patients (6 women, 39 men) diagnosed with OSA. All patien...

BACKGROUND The simultaneous occurrence of metabolic syndrome and excessive daytime sleepiness are very common in obstructive sleep apnea (OSA) patients. Both conditions, if present in OSA, have been reported to be associated with inflammation and disruption of oxidative stress balance that impair the cardiovascular system. To verify the impact of daytime sleepiness on inflammatory and oxidative...

The objectives of this cross-sectional study were: (1) To determine if night-time sleep disturbance, daytime sleepiness, or urinary incontinence were associated with an increased risk of falling in older Australian women and (2) to explore the interrelationships between daytime sleepiness, night-time sleep problems, and urge incontinence. Participants were 782 ambulatory, community-dwelling wom...
