BACKGROUND: This study translated the Adolescent Sleep Hygiene Scale-revised (ASHSr) into Persian and aimed to validate its psychometric properties using classical test theory and Rasch analyses. METHODS: Adolescents aged 14-18 (n = 389; 199 males) and their parents in Iran participated in the study. Each adolescent wore a wrist actigraphy device during sleep time and completed the ASHSr, the Depression Anxiety Stress Scale (DASS), the General Health Questionnaire (GHQ), the Pediatric Daytime Sleepiness Scale (PDSS), and the Pittsburgh Sleep Quality Index (PSQI)...

A great pioneer in sleep research, Michel Jouvet applied rigorous scientific methods to the study of sleep-wake states and associated changes in consciousness which, with his vivid imagination and creative mind, he unveiled as the mysteries of sleep and waking such as to inspire a generation of researchers in the field. His initial discovery of a third state distinguished from waking (W) and slow wave sleep (SWS) by the paradoxical association of W-like cortical activity with sleep-like behavior and muscle atonia that he accordingly called "paradoxical sleep" (PS) began his investigation over some 50 years of the mechanisms of these three sleep-wake states...

OBJECTIVE: To characterize the insomnia suffered by Franz Kafka (1883-1924), one of the most important literary figures of the 20th century. METHODS: We read Kafka's diaries and private correspondence to his fiancée, friends, editors and relatives looking for references to his insomnia. RESULTS: We found 292 references to insomnia indicating that Kafka suffered from chronic insomnia disorder that originated from and was maintained by the following predisposing and precipitating factors: (1) a complex personality predisposing to an increased arousal level, (2) intrusive thoughts and ruminations at bedtime, (3) excessive worrying about sleep loss and its daytime consequences, and (4) an extraordinary intolerance to noise...

OBJECTIVE: Sleep dysfunction has been speculated to be involved in the pathological mechanism of nocturnal enuresis (NE). However, results obtained from previous studies were conflicting. This study evaluated and compared the sleep patterns and problems between children with and without nocturnal enuresis (NE) across different age and gender groups in a large epidemiological study. METHODS: A multi-center, cross-sectional, epidemiological study was carried out in which 21,439 primary school children (10,655 boys and 10,784 girls aged 5...

BACKGROUND/OBJECTIVE: Many studies have shown a U-shaped association of sleep duration with mortality; however, this association is difficult to interpret owing to possible reverse causation, residual confounding, and measurement issues. We used data from the Women's Health Initiative to examine the associations of sleep duration, insomnia, and use of sleep aids with death from cardiovascular disease (CVD), cancer, "other" causes, and all causes combined. METHODS: Cox proportional hazards models were used in the analysis of baseline data and in time-dependent analyses of repeated measures to estimate associations of sleep-related factors with mortality...

OBJECTIVE: The aim of this study was to assess cardiovascular autonomic modulation in children with upper airway obstruction (UAO), to compare this modulation to that of non-snoring children and to investigate the effect of adenotonsillectomy (AT). METHODS: ECG and finger photoplethysmographic signals obtained from overnight polysomnographic (PSG) recordings of 31 children with mild-to-moderate UAO and 34 non-snoring children were analysed. The extent of autonomic modulation was assessed by symbolic analysis of heart period (HP), pulse wave amplitude (PWA), and their joint dynamics during non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep...

OBJECTIVE: Recent genome-wide association studies (GWASs) have revealed new genetic variants behind self-reported individual circadian preference, a distinct biological trait that is fairly stable during adulthood. In this study we analyze whether these genetic variants associate with objectively measured sleep timing from childhood to adolescence, over a nine-year period, with self-reported circadian preference during late adolescence. METHODS: The participants (N = 100, 61% girls) came from a community cohort from Finland born in 1998...

OBJECTIVE: This study investigated the association between secondhand-smoke (SHS) exposure and sleep disturbance symptoms. METHODS: This study was a cross-sectional survey of junior and senior high school students throughout Japan. A total of 85,931 adolescents responded, and 84,988 questionnaires were included in the analysis. RESULTS: Adolescents who had never smoked accounted for 88.0% of respondents; among that group 39.1% reported having been exposed to SHS over the previous week...

OBJECTIVE: Although physical activity (PA) is associated with a reduction of a wide range of sleep problems, it remains uncertain whether complying with the international guidelines of 150 min of moderate to vigorous PA per week can reduce sleep problems in adults. This research investigated the relationship between compliance with the PA recommendations of the World Health Organization and sleep problems in 38 low- and middle-income countries (LMICs). METHODS: Cross-sectional, community-based data from the World Health Survey were analyzed...

OBJECTIVE: Parents are often the first to report children's sleep difficulties. The aim of the present study was to evaluate the accuracy of parent reports by examining the correspondence of maternal and paternal reports of children's sleep with in-home electroencephalography (EEG) sleep assessment and sleep diary reports. METHODS: A total of 143 children (57 formerly very preterm born children) aged 7-12 years underwent one night of in-home sleep-EEG; mothers and fathers reported children's sleep-related behavior by using the German version of the Children's Sleep Habits Questionnaire, and children and parents together completed a sleep diary of children's sleep...

BACKGROUND: Electrocardiography R-wave to radial artery pulse delay (RRD) represents pulse transit time inclusive of pre-ejection period (PEP) and arterial pulse propagation time. RRD is proposed to largely reflect arterial stiffness when PEP is accounted for (shorter RRD = higher arterial stiffness). Sleep disordered breathing (SDB) causes intermittent hypoxemia and sympathetic activation, which negatively influences vascular function. We aimed to examine the association of measures of SDB with RRD...

BACKGROUND: The prevalence of obese children with sleep disordered breathing (SDB) is increasing. Obesity and SDB are independent cardiovascular risk factors, of which arterial stiffness is an early sign. Pulse wave velocity (PWV), is a marker of arterial stiffness and central systolic blood pressure (cSBP) is a better predictor of cardiovascular outcome than peripheral blood pressure. Therefore, we aimed to determine PWV and cSBP in overweight/obese or normal weight children with sleep disordered breathing (SDB), and non-snoring normal weight controls...

INTRODUCTION: For several years, pineal cysts have been considered an incidental finding on brain MRI's even though research and case reports have shown a possible association of pineal cysts with headaches and sleep disturbances. This pilot study aims to evaluate sleep disorders in school-age children with an incidental pineal cyst in an otherwise normal brain MRI. METHOD: Children aged 6-12 years, who were referred for evaluation of headaches, tics, or syncope, and had an incidental pineal cyst on an otherwise normal brain MRI were included and compared to a control group of children with the same referral reasons but with a normal MRI and to a cohort of normal controls...

BACKGROUND: Severe chronic vascular disease (CVD) is a major cause of co-morbidity and mortality in patients with type 2 diabetes (DM2). Sleep-disordered breathing (SDB) has been linked to CVD in the general population due to enhanced sympathetic activation, oxidative stress, endothelial dysfunction, and hypertension; however data for DM2 patients is scarce. Therefore, the aim of the present analysis to assess whether SDB is associated with CVD in patients with DM2, independent of other known associated factors...
