TL;DR: In this paper, a stepwise multiple regression analysis showed that BMI, male sex, nasal resistance, and cephalometric parameters were contributing factors to obstructive sleep apnoea syndrome (OSAS).
Abstract: Nasal obstruction has frequently been mentioned as a possible risk factor in obstructive sleep apnoea syndrome (OSAS). Over a 2-yr period, 541 unselected consecutive snorers referred for suspected breathing disorders during sleep were included to undergo posterior rhinomanometry. In addition cephalometric landmarks and body mass index (BMI) were obtained. Polysomnography was used to determine the number of abnormal respiratory events that occurred during sleep. OSAS was defined as 15 episodes, or more, of apnoea or hypopnoea per hour of sleep (AHI). Of the 541 consecutive snorers 528 underwent nasal resistance measurement by posterior rhinomanometry (failure rate: 2.4%). Patients with OSAS (259 patients) had higher nasal resistance than patients without OSAS (2.6+/-1.6 hPa x L x s(-1) versus 2.2+/-1.0 hPa x L x s(-1), respectively, p<0.005). A stepwise multiple regression analysis showed that BMI, male sex, nasal resistance, and cephalometric parameters were contributing factors to the AHI. The r2-value of the multiple regression analysis was 0.183. Nasal resistance contributed 2.3% of the variance (p<0.0001), whereas mandibular plane-hyoid distance, BMI, male sex and age contributed 6.2%, 4.6%, 3% and 1.3% of the variance, respectively. To conclude, daytime nasal obstruction is an independent risk factor for OSAS.

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: The epidemiological study of hypersomnia symptoms is still in its infancy; most epidemiological surveys on this topic were published in the last decade and inconsistencies in its definition and measurement limit the generalization of the results.

TL;DR: A large percentage of the women experienced sleep disturbances during pregnancy, These problems included frequent night wakings, difficulty falling asleep, and symptoms of sleep apnea.
Abstract: Objective To assess sleep patterns and prevalence of sleep disturbances during pregnancy. Design Cross-sectional design; prospective questionnaire. Setting Outpatient, private obstetric clinic. Participants 127 consecutive patients, with women evaluated at one of four points in pregnancy, 8–12 weeks (n=37), 18–22 weeks (n=28), 25–28 weeks (n=24), and 35–38 weeks (n=38). Main Outcome Measure Questionnaire of sleep habits and sleep disturbances. Results A large percentage of the women experienced sleep disturbances during pregnancy, These problems included frequent night wakings, difficulty falling asleep, and symptoms of sleep apnea. Few differences in sleep patterns were found across pregnancy, although women were found to sleep more and nap more by the end of pregnancy. Conclusion Sleep disturbances are common during pregnancy, especially late in pregnancy.
