TL;DR: Although the groups did not differ in self-reported sleep habits, multiple concerns were reported by parents of overweight participants, including daytime sleepiness, parasomnias, and inadequate sleep.
Abstract: Objective To document the sleep of overweight adolescents and to explore the degree to which weight-related sleep pathology might account for diminished psychosocial outcome. Methods Sixty children aged 10–16.9 from a weight-management clinic were compared to 22 healthy controls using comprehensive actigraphic, polysomnographic, and parentand self-report questionnaire assessments. Results Overweight participants averaged more symptoms of sleep-disordered breathing, later sleep onset, shorter sleep time, and more disrupted sleep than controls. Although the groups did not differ in self-reported sleep habits, multiple concerns were reported by parents of overweight participants, including daytime sleepiness, parasomnias, and inadequate sleep. Group differences in academic grades and depressive symptoms were at least partially accounted for by short sleep and daytime sleepiness. Conclusions Excessive weight is associated with an increased risk of sleep problems. There is a need for further research in this area and for clinicians who work with overweight children to evaluate their sleep.

TL;DR: Results from the sleep laboratory do not seem to support the subjective complaints of poor sleep in patients with obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD), and no significant differences were found in all sleep parameters between social phobia patients and controls.
Abstract: Many patients suffering from the majority of anxiety disorders complain about their sleep by reporting difficulties in initiating and maintaining it. Polysomnographic studies have shown that, in comparison to normal subjects, the sleep of patients with panic disorder is characterized by longer sleep latency, increased time awake and reduced sleep efficiency. Sleep architecture is normal and there are no significant changes in REM sleep measures. Nocturnal panic attacks are non-REM-related events and occur without an obvious trigger in 18-45% of panic disorder patients. Regarding generalized anxiety disorder, the patients complain of 'trouble sleeping' in 60-70%, while polysomnography has shown increased sleep latency and decreased sleep continuity measures. The findings in REM sleep and sleep architecture generally do not show any aberration to exist. In patients with obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD), results from the sleep laboratory do not seem to support the subjective complaints of poor sleep. The early reports of shortened REM latency in OCD could not be replicated by recent studies. A dysregulation of the REM sleep control system has been reported for patients with PTSD. Finally, no significant differences were found in all sleep parameters between social phobia patients and controls.

TL;DR: Service-related illnesses are prevalent in military personnel who undergo polysomnography with significant associations between PTSD, pain syndromes, and insomnia.
Abstract: STUDY OBJECTIVES Describe the prevalence of sleep disorders in military personnel referred for polysomnography and identify relationships between demographic characteristics, comorbid diagnoses, and specific sleep disorders. DESIGN Retrospective cross-sectional study. SETTING Military medical treatment facility. PARTICIPANTS Active duty military personnel with diagnostic polysomnogram in 2010. MEASUREMENTS Primary sleep disorder rendered by review of polysomnogram and medical record by a board certified sleep medicine physician. Demographic characteristics and conditions of posttraumatic stress disorder (PTSD), mild traumatic brain injury (mTBI), anxiety, depression, and pain syndromes determined by medical record review. RESULTS Primary sleep diagnoses (n = 725) included: mild obstructive sleep apnea (OSA), 207 (27.2%); insomnia, 188 (24.7%); moderate-to-severe OSA, 183 (24.0 %); and paradoxical insomnia,39 (5.1%); behaviorally induced insufficient sleep syndrome, 68 (8.9%) and snoring, 40 (5.3%) comprised our control group. Short sleep duration (< 5 h) was reported by 41.8%. Overall 85.2% had deployed, with 58.1% having one or more comorbid diagnoses. Characteristics associated with moderate-to-severe OSA were age (adjusted odds ratio [OR], 1.03 [95% confidence interval {CI}, 1.0-1.05], sex (male) (adjusted OR, 19.97 [95% CI, 2.66-150.05], anxiety (adjusted OR, 0.58 [95% CI, 0.34-0.99]), and body mass index, BMI (adjusted OR 1.19 [95% CI, 1.13-1.25]; for insomnia, characteristics included PTSD (adjusted OR, 2.12 [95% CI, 1.31-3.44]), pain syndromes (adjusted OR, 1.48 [95%CI, 1.01-2.12]), sex (female) (adjusted OR, 0.22 [95% CI, 0.12-0.41]) and lower BMI (adjusted OR, 0.91 [95% CI, 0.87, 0.95]). CONCLUSIONS Service-related illnesses are prevalent in military personnel who undergo polysomnography with significant associations between PTSD, pain syndromes, and insomnia. Despite having sleep disorders, almost half reported short sleep duration. Multidisciplinary assessment and treatment of military personnel with sleep disorders and service-related illnesses are required. CITATION Mysliwiec V; McGraw L; Pierce R; Smith P; Trapp B; Roth BJ.

TL;DR: The findings from the current study indicate that the WS may provide an easy to use and accurate complement to other established technologies for measuring sleep in healthy adults.
Abstract: The availability of a reliable system to record sleep stage measures easily and automatically in ambulatory settings could be of utility for research and clinical work. The aim of this study was to evaluate a novel wireless system (WS) that does not require skilled preparation for the automatic collection and scoring of human sleep. Twenty-nine healthy adults underwent concurrent sleep measurement via the WS, polysomnography (PSG) and an actigraph (ACT) in a sleep laboratory for one assessment night preceded by an acclimation night. The PSG recordings were scored by two experienced trained technicians from separate laboratories. Each recording was scored by both technicians to Rechtschaffen and Kales (R&K) criteria. The WS and ACT were compared with each of the PSG scores and a consensus PSG score, and the PSG scores were compared with each other. Inter-rater agreement was assessed for each pair over all pooled epochs by percentage agreement, Cohen's kappa and intraclass correlation coefficient. The WS agreement with each of the two PSG scores for sleep stages was 75.8 and 74.7%, respectively. WS agreement with each of the two PSG scores for sleep/wakefulness was 92.6 and 91.1%, ACT agreement with PSG was 86.3 and 85.7%. The PSG scorers' agreement with each other for sleep stages was 83.2%, and for sleep/wakefulness was 95.8%. The findings from the current study indicate that the WS may provide an easy to use and accurate complement to other established technologies for measuring sleep in healthy adults.

TL;DR: Both psychosocial and physiological stress are related to increased nightly variability in individuals' sleep duration and fragmentation, particularly among those reporting negative emotions, which may have implications for both sleep and health research.
