According to the apnea-hypopnea index, patients were divided into 3 groups: mild, moderate, and severe (n = 23, 59, and 94, respectively). PSG was performed, and HRV (frequency domain analysis), sleep stage (S1, S2, S3, REM, and waking), and sleep fragmentation index (SFI) were measured during the initial 3-h sleep periods. The total S1 time was significantly longer in the severe group than in the mild and moderate groups (p < 0.001). The severe group had significantly shorter total S2 and S3 times than the mild (p = 0.014, p < 0.001) and moderate (p = 0.034, p = 0.029) groups did. The SFI was significantly greater in the severe group than in the mild and moderate groups (p < 0.001, p = 0.008). The high-frequency component (HF) of the HRV showed no significant differences except that it was significantly smaller during S3 in the moderate group than in the mild group (p = 0.026). Compared with those with mild/moderate status, patients with severe OSA have shallower sleep and a higher SFI, suggesting poorer sleep quality. Although HF during S3 was significantly smaller in the moderate group, it did not significantly differ between the mild and severe groups, suggesting that the parasympathetic nervous system might compensate for humoral and hypoxemic abnormalities in patients with severe OSA.","PeriodicalId":21896,"journal":{"name":"Sleep and Biological Rhythms","volume":"23 2","pages":"181-188"},"PeriodicalIF":1.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11971072/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796481","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}

Obstructive sleep apnea (OSA) is characterized by a high apnea-hypopnea index (AHI) and persistent daytime sleepiness. Body roundness index (BRI), calculated using waist circumference and height, is a measure of obesity. BRI demonstrates a stronger correlation with body fat compared to BMI. However, no studies have thus far reported on the association between BRI and OSA. The data for this study were sourced from the National Health and Nutrition Examination Survey (NHANES) database (2005-2008 and 2015-2018). BRI was computed as 364.2-365.5 * (1 - [WC(m)/2π]2/[0.5 * height(m)]2)½. Statistical methods for data analysis included multivariable logistic regression, trend tests, restricted cubic spline (RCS) plots, subgroup analysis, and interaction tests, with a significance level of p < 0.05. This cross-sectional study investigated the relationship between BRI and OSA in 8106 American adults. After adjusting for all considered covariates, BRI was found to be positively associated with the risk of OSA, with each 1-unit increase in BRI raising the risk of OSA by 167% (95% CI [2.42, 2.95], p < 0.001). The positive association between BRI and OSA was consistent across all subgroups (p < 0.001). The restricted cubic spline (RCS) plot further confirmed the positive correlation between BRI and OSA prevalence (p value < 0.0001, p nonlinear < 0.0001). The results of this study demonstrate a positive correlation between BRI and OSA, suggesting that BRI could be utilized as a predictive factor for OSA. BRI could assist clinicians in the diagnosis of OSA in patients.Supplementary information: The online version contains supplementary material available at 10.1007/s41105-024-00566-5.","PeriodicalId":21896,"journal":{"name":"Sleep and Biological Rhythms","volume":"23 2","pages":"171-179"},"PeriodicalIF":1.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11971107/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796339","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 total of 91 college students (male, mean age 20.47 ± 2.02 years) completed one-hour mid-day nap with polysomnographic recording in a sleep laboratory. Upon awakening, self-ratings of sleep quality and sleepiness were assessed using questionnaires. The sleep structure of mid-day naps varied among participants: 47.3% participants experienced stage-1, -2, and -3 non-rapid eye movement (NREM) sleep in sequence in the one-hour nap, while rapid eye movement (REM) sleep occurred between 40 and 60 min after lights off in 27.5% participants, and less than 15 min in 16.5% participants. After nap, participants who achieved stage-3 sleep reported better sleep quality, but the subjective sleepiness was not influenced by the sleep stage contained in nap or the sleep stage at awakening. These findings highlight the diversity in the sleep structure of mid-day naps, suggesting that this variability may need to be considered when studying the effects of napping.","PeriodicalId":21896,"journal":{"name":"Sleep and Biological Rhythms","volume":"23 2","pages":"197-204"},"PeriodicalIF":1.0,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11971095/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796484","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}

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 (r = - 0.140, p < 0.01; r = - 0.174, p < 0.01). The living environment (β = - 0.049, p < 0.001) was a negative predictor of PSQI, while depression (β = 0.477, p < 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.","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}
