RESUMO

OBJECTIVES: Although common, sleep disorders often remain undiagnosed in psychiatric patients. A screening instrument, like the Holland Sleep Disorders Questionnaire (HSDQ) could improve this. Previous work indicated a 6-factor structure for the HSDQ, but this hasn't been investigated in psychiatric patients. METHODS: HSDQ data was collected in a psychiatric-outpatient sample (n = 1082) and general-population sample (n = 2089). Internal reliability of the HSDQ was investigated and Confirmatory Factor Analyses (CFA) were used to compare 1-, 6-, and second-order 6-factor models in both samples. Next, multigroup-CFA was used to investigate measurement invariance. RESULTS: Except for one subscale, internal reliability was acceptable in both samples. The 6-factor structure model fitted best in both samples and investigation of measurement invariance showed evidence for equality of the overall factor structure (configural invariance). Addition of equality constraints on factor loadings (metric invariance) and item thresholds (scalar invariance) showed good fit for all fit statistics, except for one. Exploratory analyses identified three items for metric and three different items for scalar invariance explaining this non-invariance. CONCLUSION: The HSDQ has a 6-factor structure in psychiatric patients, which is comparable to the general population. However, due to the observed non-invariance, users should be cautious with comparing HSDQ scores between psychiatric and general populations.

RESUMO

Primary care clinicians are well-equipped to screen for sleep concerns, help some patients, and refer patients whose sleep troubles are more complex to specialists. Poor sleep affects nearly every organ system and influences many morbidity and mortality causes, so screening for sleep sufficiency and quality should be prioritized in primary care settings. This commentary on a case suggests strategies for more fully supporting primary care clinicians' compensation and capacity for conducting effective conversations with patients experiencing sleep trouble.

RESUMO

Short sleep duration, poor sleep quality, and irregular timing of sleep are prevalent sleep troubles for children, but fully assessing children's sleep environments and effectively promoting children's overall sleep health is nearly impossible during brief clinical encounters. This commentary on a case suggests strategies for navigating this problem with a patient- and family-centered approach that prioritizes identifying family sleep-related beliefs, values, and goals and maintaining flexibility when offering evidence-based recommendations to improve children's sleep.

RESUMO

BACKGROUND: It has been suggested that up to 40% of dementia cases worldwide are associated with modifiable risk factors; however, these estimates are not known in Canada. Furthermore, sleep disturbances, an emerging factor, has not been incorporated into the life-course model of dementia prevention. OBJECTIVE: To estimate the population impact of 12 modifiable risk factors in Canadian adults including sleep disturbances, by sex and age groups, and to compare with other countries. DESIGN: Cross-sectional analysis of Canadian Longitudinal Study on Aging baseline data. SETTING: Community. PARTICIPANTS: 30,097 adults aged 45 years and older. MEASUREMMENTS: Prevalence and Population Attributable Fractions (PAFs) associated with less education, hearing loss, traumatic brain injury, hypertension, excessive alcohol, obesity, smoking, depression, social isolation, physical inactivity, diabetes, and sleep disturbances. RESULTS: The risk factors with the largest PAF were later life physical inactivity (10.2%; 95% CI, 6.8% to 13%), midlife hearing loss (6.5%; 3.7% to 9.3%), midlife obesity (6.4%; 4.1% to 7.7%), and midlife hypertension (6.2%; 2.7% to 9.3%). The PAF of later life sleep disturbances was 3.0% (95% CI, 1.8% to 3.8%). The 12 risk factors accounted for 51.9% (32.2% to 68.0%) of dementia among men and 52.4% (32.5% to 68.7%) among women. Overall, the combined PAF of all risk factors was 49.2% (31.1% to 64.9%), and it increased with age. CONCLUSION: Nearly up to 50% of dementia cases in Canada are attributable to 12 modifiable risk factors across the lifespan. Canadian risk reduction strategies should prioritize targeting physical inactivity, hearing loss, obesity, and hypertension.

RESUMO

BACKGROUND: Advanced cancer patients commonly suffer from a fatigue-sleep disturbance symptom cluster. Baduanjin is considered a promising mind-body exercise for relieving the fatigue-sleep disturbance symptom cluster. However, few studies have investigated a tailored Baduanjin for advanced cancer patients. The proposed study will create an optimized Baduanjin exercise program to adapt to advanced cancer patients and evaluate the effect of a Simple Sitting Baduanjin (SSBDJ) mind-body exercise on the fatigue-sleep disturbance symptom cluster among advanced cancer patients. METHODS: The study will be a prospective, assessor-blinded, two-arm, randomized controlled trial, involving a 12-week intervention and 4-week follow-up. A total of 108 advanced cancer patients experiencing the fatigue-sleep disturbance symptom cluster will be recruited from two tertiary general hospitals in China. Participants will be randomized to an experimental group (n = 54) or a control group (n = 54). The experimental group will receive a 12-week SSBDJ intervention plus the usual care, and the control group will receive only the usual care. Outcomes including fatigue-sleep disturbance symptom cluster, fatigue, sleep disturbance, and quality of life will be measured before the intervention, at the 4th, 8th, and 12th weeks of the intervention, and 4 weeks after the intervention. The intention-to-treat principle and a generalized estimating equation will be used to analyze data. DISCUSSION: This study may produce a new Baduanjin exercise prescription that is user-friendly, simple to execute, more targeted, and adaptable. If proven effective, this approach may be integrated into routine cancer care to manage the fatigue-sleep disturbance symptom cluster and improve QOL in advanced cancer patients. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCTR-2,300,072,331. Registered on 9 June 2023.

RESUMO

INTRODUCTION: Sleep is a crucial determinant of maternal and fetal health, significantly impacting the well-being of both the mother and her developing fetus. Poor sleep quality, characterized by difficulties in falling asleep or staying asleep, can cause poor pregnancy outcome. Conversely, studies came with inconsistent result in the prevalence of poor sleep quality in different trimester of pregnancy. Therefore, this systematic review and meta-analysis study aimed to compare the prevalence of poor sleep quality in different trimesters. METHOD: A systematic review and meta-analysis were done on published studies. Electronic data base search was done from PubMed, Hinari, Medline and Google Scholar. Data were extracted with Excel and the analysis were done using STATA version 17. Publication bias was assessed both graphically and statistically. I-square test was used to identify heterogeneity. RESULT: In this meta-analysis, 38 studies that measured poor sleep quality using the Pittsburg Sleep Quality Index (PSQI ≥ 5) were included. The pooled prevalence of poor sleep quality was identified as 37.46% (95% CI: 29.26, 45.67) in the first trimester, 47.62% (95% CI: 42.23, 53.02) in the second trimester, and 60.05% (95% CI: 51.32, 68.78) in the third trimester. CONCLUSION: This study identified a significant discrepancy in the prevalence of poor sleep quality, which increases as gestational age advances. Therefore, this discrepancy should be addressed, and additional support should be provided to pregnant women to help them achieve adequate sleep, especially as gestational age advances.

RESUMO

The global COVID-19 pandemic has disrupted daily routines and heightened stress levels worldwide, impacting various aspects of health, including sleep. This cross-sectional study conducted in Iran aimed to investigate the impact of Ramadan Intermittent Fasting (RIF) during the pandemic on sleep disturbances and associated risk factors in adults aged ≥ 18 years. Data was collected from Iranian participants observing RIF. A structured electronic questionnaire, translated into Persian, gathered information on sociodemographics, dietary habits, sleep parameters, physical activity, and more. The study assessed sleep quality, duration, and disturbances and conducted a thorough analysis to identify risk factors associated with sleep disruptions. The study revealed that 48% of the participants experienced sleep disturbances during RIF, with 21% reporting poor sleep quality and 46% having unusual sleep duration. Various factors were associated with an elevated risk of sleep disruptions, including body mass index, place of residence, income levels, cohabitation status, family history of obesity, hypertension, diabetes, heart disease, personal history of obesity, weight fluctuations, Shisha smoking, and unemployment. The results highlight the critical importance of health promotion strategies tailored to cultural contexts. This study advocates for enhanced health education initiatives focusing on sleep hygiene and stress management, especially during periods of significant lifestyle alterations like Ramadan amid a global pandemic. Such initiatives are vital in mitigating sleep disturbances and promoting overall well-being in populations facing unique health challenges.

RESUMO

This study investigates the association between insomnia and depression severity, exploring sleep disturbances in individuals with depression. The aim is to establish a new foundation for managing patients with co-occurring depression and insomnia, using 2015 to 2016 National Health and Nutrition Examination Survey (NHANES) data. We employed a cross-sectional design, using NHANES data from 2015 to 2018. The study included 11,261 participants after excluding incomplete data. Depression severity, assessed using Patient Health Questionnaire-9 (PHQ-9) scores, served as the exposure variable. We considered various demographic and lifestyle factors as covariates in the multivariate adjustment model. Statistical analyses adhered to CDC recommendations, with sample weights incorporated to account for NHANES' complex sample design. Our study, encompassing 19,225 participants, revealed that higher PHQ-9 scores correlated with an increased likelihood of sleep disorders. In the fully adjusted model, a positive association emerged between PHQ-9 scores and trouble sleeping (OR = 3.95, 95% CI: 3.35-4.66, P < .0001). This relationship displayed an inverted U-shaped curve, with an inflection point at 28. Subgroup analysis and interaction tests indicated no reliance on factors such as gender, age, marital status, or BMI for the connection between depression severity and trouble sleeping (all P for interaction > .05). We identified a significant inverted U-shaped correlation between sleep disturbances and depression severity. This underscores the crucial importance of assessing sleep disorder risks in individuals with varying degrees of depression severity, facilitating personalized therapeutic interventions.

RESUMO

INTRODUCTION: The new American Heart Association Life's Essential 8 construct of ideal cardiovascular health now includes sleep duration. Little is known, however, about sleep duration in individuals with prior stroke. Our objective was to compare sleep duration among individuals with and without prior stroke. METHODS: Using the National Health and Nutrition Examination Surveys (NHANES) database (2005-2018), individuals 18 years or older were identified (n = 37,987 without self-reported stroke; n = 1,572 with self-reported stroke). Prevalence of normal sleep duration (7-8 or 6-8 hours/night because of multiple definitions in the literature) was compared between persons with and without self-reported history of stroke using the Rao-Scott χ2 test. Multinomial logistic regression analysis was used to evaluate the relationship between prior stroke and abnormal sleep before and after adjusting for demographic and clinical variables. RESULTS: Compared with individuals without stroke, those with prior stroke were more likely to report >8 hours/night (unadjusted odds ratio (OR) 2.03, 95% confidence interval (CI) 1.64-2.51), <7 hours/night (1.29, 1.08-1.53), and <6 hours/night (1.87, 1.53-2.29). After adjustment, these associations were attenuated (adjusted OR 1.54, 95% CI 1.22-1.94 and 1.15, 0.96-1.38 and 1.50, 1.21-1.85). DISCUSSION: US stroke survivors are more likely to have abnormal sleep duration than those without prior stroke. Limitations of this study include the cross-sectional and self-reported nature of the data.

RESUMO

BACKGROUND: Sleep disorders are one of the major public health problems, which can potentially induce inflammation and exacerbate disease activity, resulting in compromised sleep quality. This study aimed to investigate the prevalence and risk factors associated with sleep disorders among patients with inflammatory bowel disease (IBD). METHODS: Between March 2023 and February 2024, the Pittsburgh Sleep Quality Index was employed to assess sleep quality in both IBD patients and healthy control subjects. Univariate and multivariate analysis were performed to identify the risk factors associated with SD in IBD patients. RESULTS: Overall, 208 IBD patients [150 Crohn's disease (CD) and 58 ulcerative colitis (UC)] and 199 healthy individuals were included. Sleep disorders were observed in 59.6% of patients with IBD, with a higher prevalence among females (63.5%) compared to males (56.9%) (P = 0.476). The prevalence of sleep disorders in IBD patients was significantly higher than that found in healthy controls (37.7%) (all P < 0.01). The prevalence of sleep disorders  among CD and UC patients was 58% and 63.8%, respectively (P = 0.291). The multivariate analysis revealed that older age (OR, 1.070; 95% CI: 1.035-1.105, P = 0.000), smoking (OR, 2.698; 95% CI: 1.089-6.685, P = 0.032), and depression (OR, 4.779; 95% CI: 1.915-11.928, P = 0.001) were risk factors for sleep disorders in IBD patients. However, higher body mass index (OR, 0.879; 95% CI: 0.790-0.977, P = 0.017) was identified as a protective factor. CONCLUSION: Sleep disorders are common among IBD patients regardless of activity levels. Smoking and depression are the major risk factors.

RESUMO

BACKGROUND: Accumulating evidence has suggested that sleep disturbances and disorders are common in patients who undergo knee arthroplasty. Revision surgery represents one of the most catastrophic outcomes of knee arthroplasty. However, it remains unclear whether sleep traits are the causes or consequences of knee arthroplasty revision. This study aimed to genetically examine the relationships between sleep traits and knee arthroplasty revision. METHODS: To determine the causal relationship between sleep traits and knee arthroplasty revision, we employed two-sample Mendelian randomization (MR) using summary statistics from the largest publicly available genome-wide association studies (GWASs). The MR design uses genetic variants as instrumental variables to help separate causal relationships from non-causal associations. The main analyses included an inverse variance weighted (IVW) meta-analysis to obtain primary effect estimates. Sensitivity analyses involving the weighted median approach and MR-Egger regression were also conducted to check for potential pleiotropic biases. Numerous complementary sensitivity analyses were also performed to identify statistically significant causal correlations when there were horizontal pleiotropy and heterogeneity across variants. Finally, a reverse MR analysis was performed to evaluate the possibility of reverse causation. RESULTS: In the absence of heterogeneity and horizontal pleiotropy, the IVW method revealed that genetically-predicted short sleep duration short sleep duration (average sleep duration of 24 h is 6 h or less) was positively correlated with the risk of knee arthroplasty revision (odds ratio = 1.03, 95% confidence interval = 1.01-1.05, and P = 0.003), while the association between genetically-predicted long sleep duration and knee arthroplasty was negative. The reverse MR analysis did not yield evidence supporting reverse causality relation between knee arthroplasty revision and sleep phenotypes. CONCLUSION: This research indicated that, of the 10 sleep phenotypes we analyzed, only sleep duration was causally associated with knee arthroplasty revision. These discoveries added to the understanding of the role of sleep traits in the etiology of knee arthroplasty revision, which might further expand our insights into the prevention of knee arthroplasty revision.

RESUMO

The effects of tinnitus on human health are receiving increasing attention, and it is currently believed that the central compensatory response caused by peripheral hearing loss is the main pathogenesis of chronic tinnitus. Tinnitus, psychological problems and sleep disorders affect and worsen each other, and should be taken seriously in treatment strategies. Chronic tinnitus treatment strategy advocates comprehensive treatment based on sound therapy, including reducing tinnitus sound perception and improving patients' negative mood and poor sleep. Whether treating tinnitus alone or treating relevant psychological problems and sleep disorders can break the vicious circle of tinnitus, psychological problems and sleep disorders. Therefore, balancing both psychological and sleep problems, is the direction of tinnitus treatment and research. The clinical study of the treatment of tinnitus should shift from the previous single tinnitus treatment mode and a single tinnitus evaluation index to the comprehensive treatment and comprehensive evaluation indicators that balance both psychotherapy and sleep improvement.

RESUMO

The existing data do not consistently support the link between elderly adults' waist circumferences and sleep disorders. This study aimed to evaluate whether waist circumference was connected with sleep disorder in the elderly. This cross-sectional study utilized data from the 2005-2018 National Health and Nutrition Examination Survey (NHANES) regarding waist circumference, sleep disorders, and confounding factors. Included in the study were participants older than 60 who completed sleep questionnaires and waist circumference measurements. Using a multivariate logistic regression model and subgroup analyses, the relationship between waist circumference and sleep disorder was evaluated. To explore the non-linear relationship, restricted cubic spline (RCS) with three knots coupled with a logistic regression model to assess the dose-response relationship between waist circumference (continuous variables) and sleep disorder. A total of 2,545 (Weighted 14,682,916.3) elderly participants with complete information were included in the analysis and 312 (Weighted 1,777,137.8) subjects met the definition of sleep disorder. Compared with participants without sleep disorder, those with sleep disorder had a higher waist circumference (100.80 cm vs. 108.96 cm, P< 0.001). The results of the multivariable adjusted logistic regression model suggested that those in quartiles 4 (≥ 75th percentile) for their waist circumference had higher odds of sleep disorder [adjusted odds ratio (AOR) = 2.75, 95% confidence interval (CI) = 1.66-4.54, P < 0.001] compared with those in quartile 1. The RCS result showed that the OR of sleep disorder and waist circumference displayed a linear relationship (P <0.001, Non-linear P = 0.642). Age and gender subgroup analysis revealed comparable relationships between waist circumference and sleep disorder among elderly individuals. Waist circumference was associated with sleep disorders in the elderly. There was a dose-response relationship between waist circumference and the likelihood of sleep disorder. Those with a larger waist circumference were more likely to have a sleep disorder than those with a smaller waist circumference.

RESUMO

AIM: To evaluate the impact of the COVID-19 lockdown on sleep patterns and quality among nursing students in our college. DESIGN: A cross-sectional study was carried out. METHODS: A total of 302 nursing students aged 18-25 years, representing both genders and various academic levels, participated in this study. A pre-validated, self-administered questionnaire was used to assess sleep quality during COVID-19 and it was distributed through various social media platforms for data collection. RESULTS: Female students comprised the majority (92.1%) of participants. Of 332 nursing students, 302 completed the questionnaire, yielding a 91% response rate. Statistically significant differences were observed before and during the COVID-19 lockdown regarding the need to sleep after waking, feeling refreshed upon waking, satisfaction with individual sleep patterns and experiencing restless and troubled sleep (p = 0.001). Additionally, approximately one-third of nursing students (32.9%) reported poor sleep quality during the COVID-19 pandemic, with minimal impact on the total sleep hours among the studied cohorts. PUBLIC CONTRIBUTION: The COVID-19 pandemic has statistically significant impacted nursing students' sleep quality and levels. Acknowledging these challenges and planning for providing supporting measurements is essential to ensuring that nursing students can maintain their physical and mental health, which is critical for their ability to provide quality healthcare.

RESUMO

BACKGROUND: Preeclampsia and eclampsia are severe pregnancy disorders marked by hypertension and potential organ damage. The etiological basis of preeclampsia and eclampsia is not fully understood. Previous studies have revealed a link between sleep abnormality and preeclampsia/eclampsia, but the causal relationship remains unclear. In this study, we explored the genetic links between sleep and preeclampsia/eclampsia using genome-wide association study (GWAS) summary data and Mendelian randomization (MR) analysis. METHODS: RNA sequence dataset GSE114691 was downloaded from the Gene Expression Omnibus database, comprising placental tissues from patients with preeclampsia and controls. Differential expression analysis was conducted with R (v4.2.3) and DESeq2 (v1.38.3). Gene set enrichment analysis (GSEA) was carried out using HTSanalyzeR2. GWAS summary data on preeclampsia/eclampsia and genetic markers for sleep abnormality were sourced from the FinnGen Consortium and IEU genetic databases. The Mendelian randomization analysis was conducted with TwoSampleMR (v0.6.2), and the inverse variance weighted (IVW) approach was employed as the principal method. RESULTS: GSEA analysis revealed that the orexin receptor pathway showed heightened expression in the preeclampsia group versus controls. The random-effects IVW results showed that sleeplessness/insomnia has a genetic causal relationship with preeclampsia (OR = 2.08, 95% CI: 1.07-4.06, p = 0.0318), while sleep duration has evidence of regulating eclampsia (OR = 0.09, 95% CI: 0.01-0.67, p = 0.0187). CONCLUSION: This study provides significant evidence for a genetic causal association between sleep abnormalities and preeclampsia/eclampsia. [Figure: see text].
