This study aimed to analyse the current state of sleep quality among older adults in China and to examine the effects of living environment and depression on sleep quality, as well as their interrelationship(s). A survey was conducted using a self-designed questionnaire, the Pittsburgh Sleep Quality Index (PSQI), and Patient Health Questionnaire Depression Scale (PHQ-9), targeting a sample of adults ≥ 60 years of age in the central province of China, yielding 6211 valid responses. Correlation analysis indicated that the living environment was negatively correlated with both depression and PSQI score (<i>r</i> = - 0.140, <i>p</i> < 0.01; <i>r</i> = - 0.174, <i>p</i> < 0.01). The living environment (<i>β</i> = - 0.049, <i>p</i> < 0.001) was a negative predictor of PSQI, while depression (<i>β</i> = 0.477, <i>p</i> < 0.001) was a positive predictor. Mediation analysis revealed that depression acted as a mediator between the living environment and sleep quality, contributing 61.7% of the overall effect. Further analysis through hierarchical regression and simple slope plotting indicated that in a favourable living environment, the impact of depression on sleep quality was more pronounced. These findings suggest that a supportive living environment has a protective effect against poor sleep hygiene among older adults and that depression plays a significant mediating role. Intervention strategies should focus on improving living environments and implementing mental health measures to enhance sleep quality among older adults.</p>","PeriodicalId":21896,"journal":{"name":"Sleep and Biological Rhythms","volume":"23 2","pages":"153-162"},"PeriodicalIF":1.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11971074/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive search in CINAHL, Embase, Ovid MEDLINE, PubMed, Scopus, and Web of Science, following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, was conducted from inception to September 2023 to identify studies on the prevalence of PD patients with OSA. A Comprehensive Meta-Analysis software version 3.0 and R software with random-effects models were used for pooled prevalence and prediction interval analysis. We assessed heterogeneity using <i>I</i> ^<i>2</i> test and Cochran's Q-statistic and study quality with Hoy's risk of bias. Moreover, meta-regression and subgroup analysis identified factors contributing to prevalence. A total of 42 studies with 3342 participants were included. The pooled prevalence of OSA among Parkinson's disease patients was 45% (95% CI: 39-52%). Based on 95% prediction interval, the future prevalence of OSA in PD was expected to vary from 13 to 83%. Moderator analyses showed that male sex, higher BMI, and country geographical area were significantly associated with OSA prevalence, in which South and North America are the top two continents that have a high prevalence of OSA.

A cross-sectional community-based study among 251 pregnant women was conducted. Sleep disturbances using validated tools, including the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Insomnia Severity Index (ISI), STOP-Bang and single-question RLS screener tool were measured. Bivariate logistic regression was followed by multivariate logistic regression identified significant predictors. Sleep disturbances were highly prevalent, with poor sleep quality being most common (39.84%), followed by OSA (13.55%), EDS-moderate and severe category (11.56%), insomnia (9.6%), and RLS (6.80%). Proportion of pregnant women who screened positive for any sleep disturbance was 49.4%. Disturbances increased as pregnancy progressed, particularly in the third trimester. Significant predictors included increased neck circumference (aOR 1.08; <i>p</i> = 0.003), high-risk pregnancy (aOR 3.37; <i>p</i> < 0.001), and pregnancy trimester.

High-risk pregnancies were associated with increased odds of OSA, insomnia, and EDS. Our study highlights the significant burden of sleep disturbances among pregnant women, with poor sleep quality being the most prevalent. High-risk pregnancies, increased neck circumference, and multigravida status were key determinants.
