Abstract Purpose This study aimed to comprehensively review the literature and synthesize relevant data to examine the pooled prevalence of poor sleep quality (sleep impairment) and assess overall sleep quality in patients with tinnitus.Methods This meta-analysis systematically searched both English (PubMed, Embase, and Web of Science) and Chinese (Wanfang Data Chinese database, Veep Chinese Database, and Chinese National Knowledge Infrastructure) databases. Data extraction and quality assessment were independently performed by two authors. The pooled prevalence of sleep impairment and poor sleep quality was calculated via a random-effects model. Sub-group and sensitivity analyses were performed to explore the source of heterogeneity.Results A total of seven studies were included with a total sample of 3041 tinnitus participants. The pooled prevalence of sleep impairment was 53.5% (95% confidence interval: 40.2–66.8%) and the I2 was 97.8% (Q?=?7.90, p?=?0.000). There were significant differences in the prevalence of poor sleep quality between males and females (39.1% vs. 44.6%, P?=?0.034), between different PSQI cut-off values?≥?7 and?>?5 (53.1% vs. 53.8%, P?=?0.000), and between sample sizes?>?200 and?≤?200 (54.0% vs. 52.7%, P?=?0.000). In non-Asia area, the prevalence (56.6%, 95% CI: 42.6–70.5%) was lower than that in Asia areas (34.5%, 95% CI: 25.7–43.3%).Conclusion Sleep impairment is common among patients with tinnitus. Development of interventions for conditions associated with poor sleep quality should be recommended to offer a safe and efficacious solution for this population.

Women's sleep quality has been reported to change during pregnancy; prevalence estimates of poor sleep quality during pregnancy vary widely. To further understand the observed variation of findings, we conducted a meta-analysis to quantify the prevalence of poor sleep quality during pregnancy. Articles (N = 24) that reported prevalence of poor sleep quality as captured by the Pittsburgh sleep quality index (PSQI) >= 5 were included, with a total of 11,002 participants contributing data. PubMed, PsycINFO, and Web of Science databases were systematically searched. Results indicated that the average PSQI score during pregnancy was 6.07, 95% confidence interval (CI) [5.30, 6.85], and 45.7%, 95% CI [36.5%, 55.2%], of pregnant women experienced poor sleep quality. Longitudinal studies indicated that sleep quality decreased from second (M = 5.31, SE = 0.40) to third trimester (M = 7.03, SE = 0.85) by 1.68 points, 95% CI [0.42, 2.94]. Gestational age moderated the average PSQI scores and prevalence of PSQI scores >= 5; older samples reported higher mean PSQI scores and higher prevalence of poor sleep quality. Clinicians should be aware that some reduction in sleep quality is expected during pregnancy, but complaints of very poor sleep quality could require intervention. Future research should examine various factors underlying poor sleep quality during pregnancy. (C) 2017 Elsevier Ltd. All rights reserved.

The Sleep Quality Questionnaire was developed and its reliability and validity were estimated. Four samples involving approximately 1400 Japanese college students and employees were used to examine the factor structure, the test-retest reliability, convergent validity, and incremental validity. Sleep Quality Questionnaire scores were associated with well-being, such as general health states, depressive symptoms, chronic fatigue, and quality of life. Test-retest estimates indicated that Sleep Quality Questionnaire scores were stable over an 8-week period. The Sleep Quality Questionnaire incrementally contributes to well-being even beyond the Epworth Sleepiness Scale and to sleep duration. Overall, the data suggest that the Sleep Quality Questionnaire scale is both reliable and valid.

The purpose of this study was to investigate the safety and efficacy of Rest-ZZZ, a natural sleep supplement, in healthy adults without a diagnosed sleep disorder. This randomized, double-blind, placebo-controlled, cross-over study consisted of three 7-day supplementation periods with either Rest-ZZZ, Diphenhydramine (DPH), or Placebo, with a 7-day washout. Twenty-seven participants were randomized to one of three intervention sequences and the Healthy People Sleep Quality Index (HPSQI), Quality of Life (QoL), and Profile of Mood States (POMS) questionnaires were assessed at the beginning and end of each supplementation period. Rest-ZZZ and Placebo showed improvements in sleep-related QoL (p 收起

Objectives To investigate self-reported sleep duration, sleep timing, sleep status and influencing factors in the Chinese population. Methods This web-based cross-sectional survey was conducted in 2022, covering 31 provinces (91%) in China. 11,000 questionnaires were collected, of which 8970 were valid for analysis. Self-reported sleep habits, problems and quality were investigated. Good or fair sleep ratings, enough duration, regular, with no sleep disturbances and <30 min sleep latency was defined as a composite variable: ‘Good sleep’. Factors influencing sleep patterns and ‘Good sleep’ were analyzed by multivariate logistic regression. Results Most participants sleep less than 7 h per night (55.13%), usually go to bed at 10–12 pm (47.99%), wake up at 6–8 am (49.86%), and take less than 30 min to fall asleep (66.30%) with regular sleep schedule (76.01%). Only 12.36% have ‘Good sleep’. In the past 3 months, 46.80% of the participants reported symptoms of insomnia, and 21.54% had snoring problems. Among the adults, the young, males, college students, freelancers, and those who resided in urban areas and pandemic-free areas slept later, and the northerners woke up earlier. The adults with low-moderate and moderate income and the minors at elementary and middle school slept earlier and woke up earlier. Mid-aged adults who often napped at noon were more likely to have ‘Good sleep’ than any other age group, and urban dwellers with the same habit were more likely to have ‘Good sleep’ than people dwelled in other regions. While people who slept late, woke up too early or too late, slept too little or too much, resided at GMT 7–8 area or pandemic area, had high income, or took up some occupations (entrepreneurs/individuals, professionals, manual and non-manual workers, housewives) were less likely to get a ‘Good sleep’. Conclusions The national survey provided a sleep profile of the Chinese population. Both socio-economic status and personal sleep hygiene habits had an impact on ‘Good sleep’.

Objectives: In this preliminary, longitudinal study, our objective was to assess changes in sleep quality during an inpatient stay in a rehabilitation setting in the United States and to relate changes to patients’ demographic and clinical characteristics (i.e., age, gender, BMI, ethnicity, reason for hospitalization, pre-hospital living setting, prior diagnosis of sleep disorders, and mental health status). Methods: A total of 35 patients participated in this preliminary study (age = 61 ± 16 years old, 50% 5) at admission (86%) and discharge (80%). Using a repeated ANOVA, a significant interaction was obtained between sleep quality and the presence of a diagnosed sleep disorder [F (1, 33) = 12.861, p = 0.001, η2p = 0.280]. The sleep quality of patients with sleep disorders improved over their stay, while the sleep of patients without such disorders did not. The mean nighttime sound collection level averages and peaks were 62.3 ± 5.1 dB and 86.1 ± 4.9 dB, respectively, and the average number of sleep disturbances was 2.6 ± 1.1. Conclusion: The improved sleep observed in patients with vs. without sleep disorders might be related to the care received for treating such disorders over the stay. Our findings call for the better detection and management of poor sleep in acute inpatient rehabilitation settings. Furthermore, if our findings are replicated in the future, studies on the implementation of quiet times for medical staff, patients, and family should be performed to improve sleep quality in the inpatient rehabilitation setting.

OBJECTIVE: The aim of this study was to investigate the relationship between menopause and self-reported sleep quality in Chinese women without vasomotor symptoms. METHODS: Cross-sectional data were collected from a decoded database of the National Cheng Kung University Hospital. Menopause was defined as absence of menses for at least 12 months or a history of hysterectomy and oophorectomy. Self-reported sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). A higher global PSQI score indicates poorer self-reported sleep quality, and a global PSQI score greater than 5 differentiates poor sleepers from good sleepers. RESULTS: Of the 1,088 women recruited, 353 (32.4%) were in postmenopause status. Postmenopausal women had higher mean (SD) global PSQI scores (8.0 [3.3] vs 6.1 [2.2], P < 0.001) and a greater prevalence of poor sleepers (73.1% vs 60.8%, P < 0.001) compared with premenopausal women. Multivariate linear regression analysis showed that menopause (β = 1.532; 95% CI, 1.135 to 1.949; P < 0.001) and snoring (β = 0.764; 95% CI, 0.299 to 1.228; P = 0.001) were positively associated with global PSQI scores, whereas long sleep duration (β = -0.791; 95% CI, -1.113 to -0.468; P < 0.001) was negatively associated with global PSQI scores. Multivariate logistic regression analyses showed that menopause (odds ratio, 1.453; 95% CI, 1.030 to 2.051; P < 0.05), long sleep duration (odds ratio, 0.545; 95% CI, 0.418 to 0.710; P < 0.001), and snoring (odds ratio, 2.022; 95% CI, 1.312 to 3.116; P = 0.001) were independent predictors of poor sleepers. CONCLUSIONS: Postmenopausal women without vasomotor symptoms have significantly higher global PSQI scores and a higher risk of being poor sleepers than premenopausal women. In addition, menopause and snoring are associated with an increased risk of poor self-reported sleep quality independently of cardiometabolic factors and lifestyle, whereas long sleep duration is associated with a decreased risk of poor self-reported sleep quality.

Ichthyosis, as a debilitating disease, can cause significant physical and psychological damage to children and their families, which also includes sleep impairment. We call attention to the importance of evaluating sleep complaints in these patients, given the scarcity of studies on this subject. As the disease commonly results in severe skin injury, it can affect social relationships and the life and sleep quality of the individuals, leading to significant psychologic damage that can persist throughout their lives.
