The Complex Interaction Between the Major Sleep Symptoms, the Severity of Obstructive Sleep Apnea, and Sleep Quality
2021
Introduction: Little information exists in the general population whether clinical presentation phenotypes of obstructive sleep apnea (OSA) differ in terms of sleep quality and comorbidities.Aim: The purpose of our study was to assess possible differences between symptomatic and asymptomatic OSA patients concerning syndrome's severity, patients' sleep quality, and comorbidities.Subjects and methods: First, in a nationwide, stratified, epidemiological survey, 4,118 Cypriot adult participants were interviewed about sleep habits and complaints. In the second stage of the survey, 264 randomly selected adults underwent a type III sleep study for possible OSA. Additionally, they completed the Gre…
Sleep quality does not mediate the negative effects of chronodisruption on body composition and metabolic syndrome in healthcare workers in Ecuador
2020
Abstract Background and aims The objective of the present work was to determine to what extent sleep quality may mediate the association between chronodisruption (CD) and metabolic syndrome (MS), and between CD and body composition (BC). Methodology Cross-sectional study which included 300 adult health workers, 150 of whom were night shift workers and thereby exposed to CD. Diagnosis of MS was made based on Adult Treatment Panel III criteria. Sleep quality was measured using the Pittsburgh Sleep Quality Index. Body mass index (BMI), fat mass percentage, and visceral fat percentage were measured as indicators of body composition (BC). Data were analyzed using logistic, linear regression and …
Gender differences in variables associated with sleep quality in chronic tension type headache
2018
We aimed to evaluate gender differences in the relationships between headache features, sleep quality, anxiety, depressive symptoms, and burden of headache in 193 patients (73 percent women) with chronic tension type headache (CTTH). Sleep quality was assessed with the Pittsburgh Sleep Quality Index. Headache features were collected with a four-week diary. The Hospital Anxiety and Depression Scale was used to assess anxiety/depressive symptoms. Headache Disability Inventory was used to evaluate the burden of headache. In men with CTTH, sleep quality was positive correlated with headache frequency (r = 0.310; p = .018), emotional (r = 0.518; p < .001) and physical (r = 0.468; p < .001) burde…
Can a meditation app help my sleep? A cross-sectional survey of Calm users
2021
Use of mindfulness mobile apps has become popular, however, there is little information about subscribers’ perceptions of app content and its impact on sleep and mental health. The purpose of this study was to survey subscribers to Calm, a popular mindfulness meditation app, to explore perceived improvements in sleep and mental health, evaluate what components of the app were associated with improvements in sleep and mental health, and determine whether improvements differed based on sleep quality. Calm subscribers who had used a sleep-related component in the last 90 days completed a Web-based investigator-developed survey and the Pittsburgh Sleep Quality Index. The survey included questio…
Sleep quality in the general population: psychometric properties of the Pittsburgh Sleep Quality Index, derived from a German community sample of 928…
2017
Abstract Background The Pittsburgh Sleep Quality Index (PSQI) is frequently used to assess sleep problems in patients. The aim of this study was to provide reference values for this questionnaire, to test psychometric properties, and to analyze associations with psychological, sociodemographic, and behavioral factors. Methods A German community sample comprising 9284 adult residents (aged 18–80 years) was surveyed using the PSQI and several other questionnaires. Results According to the generally accepted cut-off (PSQI > 5), 36% of the general population slept badly. Females reported significantly more sleep problems than males (mean scores: M = 5.5 vs. M = 4.4, respectively; effect size d …
A longitudinal study of sleep disorders in early-stage chronic kidney disease
2010
Few studies have addressed the problem of sleep disturbances in patients with early-stage chronic kidney disease (CKD). A total of 220 patients newly diagnosed with CKD and 220 patients newly diagnosed with chronic hepatitis C were studied within 1 month from the diagnosis. They were evaluated by using the Charlson Comorbidity Index, the Pittsburgh Sleep Quality Index, and the Beck Depression Inventory. Patients with CKD were followed up for 4 years. Sleep disturbances affected 59.5% of patients with chronic hepatitis C and 84.6% of patients with CKD. Sleeping disorders that were severe and peculiar in early CKD improved significantly over time. Beck Depression Inventory disclosed significa…
Sleep-wake disturbances in patients with amyotrophic lateral sclerosis
2011
Objective To evaluate the frequency, severity and determinants of sleep disturbances in patients with amyotrophic lateral sclerosis (ALS). Methods Information about night-time complaints was collected using a standardised questionnaire, the Pittsburgh Sleep Quality Index (PSQI), and the Epworth Sleepiness Scale (ESS) in a group of 100 patients with ALS and in 100 control subjects matched for age and sex. Functional disability was assessed using the ALS Functional Rating Scale-Revised (ALSFRS-R). Sleep was studied by overnight polysomnography in 12 patients. Results Fifty-nine patients with ALS and 36 controls reported sleep disturbances. The mean global PSQI score of patients with ALS was s…
Orexin and sleep quality in anorexia nervosa: Clinical relevance and influence on treatment outcome
2015
Background and aims Orexins/hypocretins are orexigenic peptides implicated in the regulation of feeding behavior and the sleep/wake cycle. Little is known about the functioning of these peptides in anorexia nervosa (AN). The aims of the current study were to evaluate the extent to which orexin-A might be linked to sleep and treatment outcome in AN. Method Fasting plasma orexin-A concentrations were measured in 48 females with AN at the start of a day hospital treatment and in 98 normal-eater/healthy-weight controls. The Pittsburgh Sleep Quality Index was administered at the beginning of the treatment as a measure of sleep quality. Other psychopathological variables were evaluated with the S…
Effects of sleep apnea and kidney dysfunction on objective sleep quality in nondialyzed patients with chronic kidney disease: an ESADA study
2020
Study Objectives: Patients with chronic kidney disease (CKD) often report poor sleep quality, but they commonly exhibit OSA. The aim of this study was to evaluate the influence of OSA severity and of estimated glomerular filtration rate impairment on objective sleep quality in nondialyzed patients with CKD, defined as an estimated glomerular filtration rate <60 mL/min/1.73m2. Methods: Polysomnographic sleep characteristics were compared between patients with (n = 430) and without CKD (n = 6,639) in the European Sleep Apnea Database cohort. Comparisons were repeated in 375 patients with CKD and 375 control patients without CKD matched for sleep center, age, sex, and AHI, and in 310 matche…
Association between socioeconomic factors and sleep quality in an urban population-based sample in Germany.
2013
BACKGROUND: Good sleep quality is essential for recovery. The risk factors of sleep disorders have been extensively investigated, but there is sparse information on the association of socioeconomic factors with a person's sleep quality. The aim of the present analysis is to investigate this association, taking particularly the effect of health confounders into consideration.METHODS: The data were extracted from the cross-sectional QUEBEB Study. In total, the study sample consisted of 3281 participants (1817 women and 1464 men, aged 16-72 years). Here socioeconomic status (SES) was collected from the baseline survey taken in 2004. Sleep quality for the same participants was measured with in-…
