Prevalence of poor sleep quality during menopause: a meta-analysis.

Numerous researches have demonstrated that sleep quality deteriorates during menopause, but the prevalence rates vary between studies. The purpose of this meta-analysis was to determine the pooled prevalence of poor sleep quality during menopause and to explore potential moderators of discrepancies in prevalence between studies. Web of Science, PubMed, PsycINFO and Embase databases were comprehensively searched from database creation to June 19, 2024. Studies were included if they focused on menopausal women and provided an estimate of the prevalence of poor sleep quality, which could be derived from the Pittsburgh Sleep Quality Index (PSQI). Totally, 37 studies with 29,284 menopausal women were included in the analysis. A meta-analysis based on a random-effects model revealed that the prevalence of poor sleep quality during menopause was 50.8% (95% CI: 45.4-56.3%). The PSQI score was 6.24 (95% CI: 5.73-6.75). Subgroup analyses indicated that cut-off values of PSQI, menopausal status, age range, depressive symptoms and geographic region moderated the prevalence of poor sleep quality. Meta-regression analyses indicated that quality score was negatively correlated with the pooled prevalence. Poor sleep quality is a prevalent phenomenon among women during menopause. In light of the numerous adverse effects of poor sleep quality on menopausal women, it is of paramount importance to assess sleep quality on a regular basis and to implement effective interventions for menopausal women.

Demographic correlates, lifestyle habits, and health effects of poor sleep quality in Indian adolescent girls living in a second-tier city

Background: Insufficient sleep, poor sleep quality, and sleepiness are common problems related to learning, memory, and school performance. During puberty, sleep habits change earlier among girls in parallel to their earlier pubertal maturity. The changes occur during adolescence in response to maturational changes and increased autonomy and independence. Aims and Objectives: This study aims to estimate the prevalence of poor sleep quality among adolescent girls in a second-tier city. Materials and Methods: Cross-sectional observational study conducted in 150 school-going adolescent girls from three different schools in a second-tier city. The study was conducted using the Pittsburgh Sleep Quality Index scale for assessment of the quality of sleep and an investigator designed pro forma to analyze various lifestyle habits. Kutcher Adolescent Depression Scale 6 was used to address the depressive symptoms. Results: Prevalence of poor sleep quality was 9.2%. Pre-bed screen time of >30 min was found in 53% of girls with poor sleep quality. Overweight girls also have poor sleep quality. Good grades (>90% marks in examinations) were associated with poor sleep quality. About 8.3% of girls with poor sleep quality have one or more symptoms pertaining to depression. Conclusion: The pre-bed screen time of more than 30 min in the form of any electronic screens leads to poor sleep quality and poor sleep quality is significantly associated with being overweight. Poor sleep quality is also associated with some symptoms of depression. These all are observed in the girls living in a tier two city, awareness among adolescent girls must be spread to decrease the screen time and they should also be encouraged for better sleep hygiene.

Pregnancy Concerns as Predictors of Sleep Quality in Primigravid Women: A Cross-Sectional Study.

Introduction Poor sleep quality may be a risk factor for adverse pregnancy outcomes. Identifying the predictors of sleep disorders can help design effective interventions. The present study aimed to evaluate the impact of pregnancy concerns on the sleep quality of primigravid women. Methods This cross-sectional study was conducted on 220 primigravid women referred to health centers in Hamadan, Iran. In addition to completing the demographic characteristics questionnaire, the Parkinson's Disease Questionnaire (PDQ) questionnaire was completed to determine the level of pregnancy concerns, and the Pittsburgh Sleep Quality Index (PSQI) questionnaire was completed to determine the quality of sleep by pregnant women. Data were analyzed using descriptive statistics, the Pearson correlation coefficient, independent t-test, and univariate and multivariate logistic regression models with a backward method at a 95% confidence level. Results Pregnant women's total PSQI score was 13.8 ± 3.08, and with a PSQI ≥ 5 as a cut-off point, 76.3% of the study's participants had poor sleep quality. There was a significant direct correlation between the total score of PDQ and its subscales with the total PSQI score (P < 0.05). The adjusted regression logistic model showed a significant relationship between the PDQ scores, women'seducational level (adjusted odds ratio (AOR) 1.19; confidence interval (CI) 95%: 0.19-2.18), and their spouse's educational level (AOR 1.03; CI 95%: 0.02-2.03) with sleep quality scores. Conclusion Pregnancy concerns, including concerns about birth and the baby, concerns about physical symptoms and body image, and concerns about emotions and relationships, can reduce the sleep quality of primigravid women. Designing and implementing effective interventions to reduce or modify these common concerns can improve the sleep quality of pregnant women and prevent the adverse effects of poor sleep quality on pregnancy outcomes.

Psychosocial stress, adult suicidal ideation, and the mediating effect of poor sleep quality during the COVID-19 pandemic in South Africa.

South Africa instituted one of the world's strictest lockdowns during the COVID-19 pandemic, which generated heightened conditions of psychosocial stress and posed widespread mental health risks. Despite the elevated burdens of suicidal behaviors and risk of psychiatric disease in the country, few studies have examined the impacts of psychosocial stress from the pandemic on suicidal ideation in South Africa. This study examined the association between psychosocial stress experienced under the COVID-19 pandemic and adult suicidal ideation, as well as degree to which sleep quality and duration mediated this relationship. An online survey assessed experiences of COVID-19 psychosocial stress, sleep quality and duration, and suicidal ideation in a sample of 189 South African adults during the second and third waves of the COVID-19 pandemic. A causal inference framework for mediation analysis was used to assess the degree to which sleep quality and duration explained the association between COVID-19 psychosocial stress and suicidal ideation. Suicidal ideation was reported in 21% of adults. Adults described having moderate sleep quality and an average of 6.9 hours of sleep per night. COVID-19 psychosocial stress significantly predicted adult suicidal ideation in fully adjusted models. Sleep quality, but not sleep duration, significantly mediated the association between COVID-19 psychosocial stress and suicidal ideation, accounting for 25.9% of the total effect. Poor sleep quality may play an important role in exacerbating the alarming stress-induced mental health effects of the COVID-19 pandemic. Further research is necessary to understand the underlying sleep dynamics and associated psychological and neurobiological processes that perpetuate adult suicidal ideation.

Effect of poor sleep quality on academic performance among students at a public Saudi University

Objective: This study aimed to evaluate sleep quality and examine the relationship between poor sleep quality and low academic performance. Methods: A total of 548 students at Imam Mohammad Ibn Saud University in Riyadh, Saudi Arabia, participated in this cross-sectional study. A questionnaire included socio-demographic questions, sleep quality questions, questions about academic performance, and the Pittsburgh Sleep Quality Index. Various lifestyle factors, socio-demographic characteristics, and academic performance were examined among university students, and sleep quality was assessed. Results: Observable correlations were noted, where gender was a paramount factor, with a more significant proportion of females demonstrating substandard sleep quality than males (p &amp;lt; 0.001). Importantly, those suffering from concurrent chronic illnesses showed a distinct link to poor sleep quality (p &amp;lt; 0.003). In contrast, no significant connections were discerned about marital status, educational year, academic performance scores (GPA), intake of caffeinated beverages, employment situation, or daytime sleeping routines. These observations offer intricate perspectives on the multifaceted correlation of factors that impact sleep quality in university undergraduate students. Conclusion: The outcomes highlighted the necessity for specific initiatives, acknowledging the significance of gender and health conditions in fostering ideal sleep wellness within this population group

Quality of Sleep in the Saudi Population During the Holy Month of Ramadan.

Background The holy month of Ramadan carries a massive change in a Muslim's lifestyle. During these 30 days of all-day fasting, people in Saudi Arabia prefer staying up all night and sleeping in the daytime, thus highly impacting their regular sleeping schedule, with a sizable effect on the quality of sleep. This study aimed to measure the quality of sleep and sleep hygiene practices in the Saudi population. Methodology This cross-sectional study was conducted among the Saudi population during the holy month of Ramadan. A self-administered questionnaire was sent to the targeted population using social media platforms. Our questionnaire included demographic data, the Sleep Quality Scale (SQS) to measure sleep quality, and the Sleep Hygiene Index (SHI) to measure sleep hygiene practices. Results Of the 386 participants, 71.2% were females, and 64.5% were single. The total mean SQS score was 35.8 (SD = 10.9) out of 84 points, while the total mean SHI score was 19.8 (SD = 8.61) out of 52 points. Overall, 63.5% of the respondents had poor sleep hygiene practices. Significant factors for increased SHI included being unmarried, a student, not the main provider in the family, not a parent, and earning less than 5,000 SAR per month while having more than six individuals in the family was a significant factor for increased SQS. Conclusions During the month of Ramadan, poor sleep quality and inadequate sleep hygiene practices were common among the Saudi population. A significant risk factor for poor sleep quality was having more than six individuals at home while being unmarried, a student, not being the family's main provider, and earning less than 5,000 SAR per month were the significant risk factors for poor sleep hygiene practices. Further research is needed to establish the effect of poor sleep quality and inadequate sleep hygiene practices during Ramadan fasting in our region.

Physical activity attenuates the effect of poor sleep quality on cognitive function in adults with chronic stroke

AbstractBackgroundGood sleep quality is important for cognitive health. Individuals with chronic stroke are at an increased risk for dementia and about half have insomnia. Stroke survivors are a target population in need of intervention strategies to promote sleep quality to preserve cognitive function. Physical activity is a promising approach. Hence, in this cross‐sectional analysis, we examined whether physical activity moderates the effect of poor sleep quality on cognitive function in adults with chronic stroke.MethodThis is a cross‐sectional analysis of baseline data acquired from 121 community‐dwelling older adults with chronic stroke (age: 70.73 ± 8.56 years; 38.30% female) enrolled in a 6‐month randomized control trial. Sleep quality was assessed with the MotionWatch8 (MW8) and physical activity was measured with the Life Space Questionnaire (LSQ; 0‐120). Participants were split into higher or lower physical activity by the median LSQ score (median = 64.00). Cognitive performance was measured with the 13‐item Alzheimer’s Disease Assessment Scale (ADAS‐Cog; 0‐85), with higher scores indicating worse cognitive performance. A linear regression was performed to first assess the independent association of MW8‐measures of sleep quality (i.e., sleep duration, fragmentation, efficiency, latency, and awakenings) and ADAS‐Cog score, after accounting for age and Montreal Cognitive Assessment score (MoCA) score. Based on the results of this linear regression, we performed a second linear regression with ADAS‐Cog score as the dependent variable, and sleep latency (minutes), physical activity level, and the interaction of sleep latency * physical activity level as independent variables, controlling for age and MoCA score.ResultGreater sleep latency (β1 = 0.22, p = 0.017) was significantly associated with greater ADAS‐Cog score, after controlling for age and MoCA (R2 = .50, F(3, 105) = 34.74, p&lt;.01). Physical activity significantly moderated the association between sleep latency (β1 = 0.38, p = 0.033) and ADAS‐Cog score (R2 = .53, F(5, 103) = 22.93, p&lt;.01). Specifically, those in the higher physical activity group showed lower ADAS‐Cog scores with higher sleep latency (r = .67, p = .627) and those in the lower physical activity group showed higher ADAS‐Cog scores with higher sleep latency (r = .75, p = .007).ConclusionPhysical activity attenuates the effect of poor sleep quality on cognitive function in adults with chronic stroke.

Sleep mediates the relationship between precarious employment and mental health

BackgroundCurrent evidence suggests that precarious employment is a risk factor for poor mental health. Although the mechanisms underpinning this relationship are unclear, poor sleep has been proposed to have a role in this relationship. This study explored the mediating effects of poor sleep quality and duration on the relationship between precarious employment and mental health. MethodsData were obtained from wave 17 of the Household, Income and Labour Dynamics in Australia survey. A novel precarious employment score (PES) was developed using exploratory and confirmatory factor analyses (CFA) in 8127 workers (4195 female, aged 18–65). Structural equation modelling (SEM) was used to evaluate the mediating effect of sleep quality and duration on the relationship between precarious employment and mental health (SF-36 mental health subscale). ResultsThe PES identified 650 workers with a high level of precariousness, 2417 with a moderate level of precariousness, and 5060 workers with a low level of precariousness out of 8127 in total. There was a significant direct association between precarious employment and mental health; with higher precarity increasing the likelihood of poor mental health. The SEM results revealed that sleep quality partially mediated the association between precarious employment and mental health (Coefficient = 0.025, 95 % CI [0.015, 0.034], P ≤ 0.001). However, a mediation effect was not found for sleep duration. ConclusionEncouraging precarious employees to improve sleep quality may mitigate the adverse effects of precarious work on their mental health. Further objective measurement of sleep duration warrants a more accurate insight into this mediating effect in this group.

Exploring the mediating effects of academic performance and self-esteem on the influence of sleep quality on internalizing and externalizing problems among Chinese adolescents

ABSTRACT This study examines the associations between sleep quality and internalizing and externalizing problems among Chinese adolescents and investigates whether academic performance and self-esteem function as mediators. Data were obtained from the 2018 wave of the China Family Panel Studies (CFPS), comprising a sample of 1,016 Chinese adolescents aged between 10 and 15 years. We employed multiple mediation models, using Hayes’ PROCESS macro, for data analysis. The results showed that poor sleep quality was associated with an increase in both internalizing and externalizing problems. Furthermore, academic performance and self-esteem were identified as mediators in these relationships, operating in parallel and sequential manners. Besides maintaining adequate sleep hours, interventions aimed at improving academic performance and self-esteem could potentially alleviate the adverse effects of poor sleep quality on internalizing and externalizing problems among adolescents.

Sleep quality, fatigue, societal participation and health-related quality of life in kidney transplant recipients: a cross-sectional and longitudinal cohort study.

Fatigue and impaired health-related quality of life (HRQoL) are common among kidney transplant recipients (KTR). We hypothesized that both may partially be attributable to poor sleep. Cross-sectional and longitudinal data of KTR enrolled in the TransplantLines Biobank and Cohort Study were used. Sleep quality was assessed using the Pittsburgh Sleep Quality Index questionnaire. Individual strength (i.e. a composite of fatigue, concentration, motivation and physical activity), societal participation and HRQoL were assessed using validated questionnaires. We included 872 KTR (39% female, age 56±13 years) and 335 healthy controls. In total, 33% of male KTR and 49% of female KTR reported poor sleep quality, which was higher compared with male and female healthy controls (19% and 28%, respectively, P<.001 for both). In logistic regression analyses, female sex, anxiety, active smoking, low protein intake, physically inactive lifestyle, low plasma magnesium concentration, using calcineurin inhibitors, not using mTOR inhibitors and using benzodiazepine agonists were associated with poor sleep quality. In adjusted linear regression analyses, poor sleep was strongly and independently associated with lower individual strength [standardized β (st.β) = 0.59, 95% confidence interval (CI) 0.45 to 0.74, P<.001], poorer societal participation (frequency: st.β = -0.17, 95% CI -0.32 to -0.01, P=.04; restrictions: st.β = -0.36, 95% CI -0.51 to -0.21, P<.001; satisfaction: st.β = -0.44, 95% CI -0.59 to -0.28, P<.001) and lower HRQoL (physical: st.β = -0.53, 95% CI -0.68 to -0.38, P<.001; mental: st.β = -0.64, 95% CI -0.78 to -0.50, P<.001). The associations with poorer societal participation and lower HRQoL were strongly mediated by individual strength (P<.001 for all), yet the suggested direct effects of poor sleep quality on HRQoL remained significant (Pphysical=.03, Pmental=.002). Longitudinal data of 292 KTR showed that sleep quality improves after kidney transplantation in males (P<.001), but not in females (P=.9). Poor sleep quality is common among KTR, and may be a potential target to improve fatigue, societal participation and HRQoL among KTR.

The relationship between sleep quality and occupational well-being in employees: The mediating role of occupational self-efficacy.

This study aimed to examine the impact of sleep quality on occupational well-being in employees by primarily focusing on the mediating role of occupational self-efficacy. A total of 487 junior staff completed a set of questionnaires comprised Pittsburgh Sleep Quality Index scale, Occupational Self-efficacy Scale, and occupational well-being measurements. The results revealed that both sleep quality and occupational self-efficacy were significantly correlated with occupational well-being. The structural equation modeling analysis and the bootstrap test indicated that occupational self-efficacy partially mediated the effect of poor sleep quality on occupational well-being. These findings expand upon existing research on the relationship between sleep quality and well-being among occupational workers, shed light on the correlation of poor sleep quality with occupational well-being, and are valuable in promoting the occupational well-being of employees.

Be prepared: Does psychological reattachment buffer the effect of a bad night's sleep on day‐specific work engagement and proactivity?

AbstractPsychological reattachment means mentally tuning into one's work before starting work in the morning. In this daily diary study, we investigated whether psychological reattachment may be beneficial not only for work engagement but also for proactivity during the day. We moreover considered two competing theoretical propositions regarding the role of psychological reattachment in the effect of sleep quality on work engagement and proactivity. The first proposition assumes a cognitive, self‐regulatory perspective in which psychological reattachment serves as a moderator, buffering the detrimental effect of poor sleep quality on work engagement and proactivity. The second proposition assumes an energetic process in which psychological reattachment may benefit from a good night's sleep and thus serve as a mediator for the beneficial effect of sleep quality on work engagement and proactivity. We conducted a daily diary study over ten consecutive workdays. Altogether, we collected data from 171 employees on 1186 days. The results indicated that on days with good sleep quality and higher psychological reattachment, work engagement and proactivity were higher. Day‐specific psychological reattachment buffered the negative effects of a poor night's sleep on work engagement, supporting the first of our competing hypotheses. Finally, we present ideas on how to foster psychological reattachment in practice.

The Relationship between Sleep Quality and Blood Pressure in Students of the Faculty of Medicine, Universitas Prima Indonesia

Poor sleep quality is one of the risk factors for high blood pressure or hypertension in adults. Disorders of the cardiovascular system are believed to be one of the effects of poor sleep quality. This study aims to determine the relationship between sleep quality and cardiovascular performance of students at the Faculty of Medicine, Universitas Prima Indonesia, as assessed by systolic and diastolic blood pressure. This study is an observational study with a cross-sectional approach. A total of 75 subjects participated in this study. Sleep quality was assessed by PSQI, and blood pressure was assessed by an aneroid tensimeter. This study shows that sleep quality is related to blood pressure. Poor sleep quality is associated with increased blood pressure, p&lt;0.05. Sleep quality is related to blood pressure in students of the Faculty of Medicine, Universitas Prima Indonesia.

Analysing the role of sleep quality, functional limitation and depressive symptoms in determining life satisfaction among the older Population in India: a moderated mediation approach

Background:Life satisfaction (LS), a useful construct in the study of psycho-social well-being, is an important indicator of healthy aging. With a view to investigate whether the improved longevity in India is accompanied by commensurate levels of well-being and contentment among the older adults , this study aimed to examine (1) the association between LS and sleep quality among older Indian adults aged 60 years and above (2) the mediating role of depression that accounts for the association and (3) the moderating role of functional limitation in this mediation.Methods:Cross-sectional data from the Longitudinal Ageing Study in India (LASI), Wave-1 (2017-18) was used. Pearson’s correlation coefficients were calculated to investigate the pair-wise relationship between sleep quality, depressive symptoms, functional limitation, and LS. Structural Equation Model was employed to analyse the moderated-mediated association between sleep quality and the level of LS.Results:Sleep quality had a direct effect (β=-0.12) as well as an indirect effect (β=-0.024) via depressive symptoms on LS, accounting for 83.6 and 16.4 per cent of the total effects, respectively. Also, the interaction term between poor seep quality and functional limitation was positive (β = 0.03, p < 0.001) in determining depressive symptoms, suggesting that higher level of functional limitation aggravated the indirect effect of poor sleep quality on LS.Conclusion:The findings of the study suggested that ensuring both the physical as well as the mental well-being of the population during the life course may confer in later life the desired level of life satisfaction.

The moderating role of trait and state mindfulness between daily sleep and physical pain symptoms: an ecological momentary assessment and actigraphy study

Objective: Poorer sleep quality and insufficient sleep increase the risk of physical pain. The current study examined the daily associations between sleep and physical pain symptoms and tested the moderating role of trait and state mindfulness in this relationship. Methods: Sixty hospital nurses (M age=35.4 ± 11.8 years) completed 14-day ecological momentary assessment (EMA) and sleep actigraphy. EMA measured physical pain frequency and interference (1×/day) and state mindfulness (3×/day). Multilevel modelling was used to examine the associations at the between-person and within-person levels. Results: After nights with poorer sleep quality, lower sleep sufficiency, and more insomnia symptoms, the frequency of physical pain symptoms and pain interference were greater than usual. Overall, those with poorer sleep quality, lower sleep sufficiency, and more insomnia symptoms reported more physical pain symptoms and greater pain interference. Higher state mindfulness buffered the negative within-person association between sleep efficiency and physical pain frequency. There was evidence that the joint moderating effects of trait and state mindfulness yielded more protective benefits in the relationship between sleep quality and physical pain than trait or state mindfulness alone. Conclusion: Even without mindfulness training, one’s mindfulness may be protective against the adverse effects of poor sleep quality on physical pain.

Poor sleep quality and reduced immune function among college students: Perceived stress and depression as mediators

Objectives Sleep problems are highly prevalent among college students and are linked to a multitude of detrimental consequences, among which are heightened perceived stress and symptoms of depression. The present study investigated the effect of poor sleep quality on the immune function of college students. A serial mediation model was developed to test the prediction that perceived stress and depression sequentially mediate the relationship between poor sleep quality and reduced immune function among college students. Participants 137 undergraduates were recruited from a large Midwestern university (103Females, 34Males; M age = 19.47, S Dage = ± 1.54). Methods Cross-sectional based online survey administered in Spring 2021. Results Analyses revealed a significant total effect of sleep quality on immune function. Perceived stress and depression symptoms serially mediated the relationship between sleep quality and immune function. Conclusions Results underscore the importance of college students’ sleep in relation to their mental health and subsequent immune function.

Associations Between Total Sleep Duration and Cognitive Function Among Middle-Aged and Older Chinese Adults: Does Midday Napping Have an Effect on It?

AimThe effect of sleep duration on cognitive function has been reported. However, the studies about the combined effects of total sleep duration and midday napping on cognition in elders were limited and inconclusive. We aimed to investigate the associations between total sleep duration, midday napping and cognitive function among middle-aged and older Chinese adults.MethodsBased on the 3rd wave of the China Health and Retirement Longitudinal Study (CHARLS) in 2015, a total of 9218 participants aged ≥45 years with completed cognition measurements were included. Cognitive functions were assessed by a combined global cognition score of episodic memory and mental status. Information about sleep-related variables, demographic characteristics, and health status were collected by validated questionnaires. Multivariate linear regression models were performed to evaluate the associations between total sleep duration, midday napping, and cognitive function. Stratified analyses were used to explore the potential effect modifier.ResultsOverall, the global cognition score was 10.38 ± 4.30 among the participants (mean age: 61.5 ± 8.7 years). For sleep duration, both short sleep and long sleep duration were significantly associated with the increased risk of cognitive impairment after controlling for demographics and other confounders. Compared with sleeping for 7h per day, the adjusted β-coefficient and 95% CI of the risk of cognitive impairment was −0.967 (95% CIs: −1.191, −0.742) for ≤5h, −0.257 (−0.498, −0.016) for 6h, −0.424 (−0.650, −0.198) for 8h and −0.664 (−0.876, −0.452) for ≥9h. The combined effect analysis indicated that subjects with extended or without naps had a significantly higher risk of cognitive impairment in the ≤5h sleep time group (ref: 7h) and in extended nappers or without naps group (ref: short nappers). Subjects with extended naps or without naps might increase the risk of cognitive impairment, especially those having ≤5h total sleep time. Stratified analysis showed that participants aged ≥60 years without social activity increased the risk of cognitive decline.ConclusionAn inverted U-shaped association was observed between total sleep duration and cognitive function in Chinese elders, especially in those aged ≥60 years or without social activity. Short midday naps could mitigate the deleterious effects of poor sleep quality and shorter sleep duration on cognitive function. The findings could help us identify the vulnerable population and decrease the burden of cognitive impairment.

The association between sleep quality and psychological distress among older Chinese adults: a moderated mediation model

BackgroundPrevious research has found a link between sleep quality and psychological distress. However, the underlying mechanisms of this connection have still not been well explored. The aim of this study was to examine the roles of activities of daily living (ADL), physical activity, and perceived social support in the link between sleep quality and psychological distress among older adults.MethodsThree thousand two hundred fifty valid individuals (aged 60 years or above) participated in face-to-face questionnaire-based surveys. Older individuals were assessed using the Pittsburgh Sleep Quality Index, Barthel Index, International Physical Activity Questionnaire, Perceived Social Support Scale, and Depression Anxiety Stress Scale-21. The PROCESS macro developed by Hayes was used to conduct moderated mediation analysis.ResultsIn older adults, sleep quality had a substantial direct influence on psychological distress. ADL mediated the association between sleep quality and psychological distress. Physical activity significantly reduced ADL’s mediating influence on the relationship between sleep quality and psychological distress. Furthermore, perceived social support moderated the direct relationship between sleep quality and psychological distress, as well as the second half of the mediating effect of the ADL. Moreover, physical activity and perceived social support were preventive factors that might successfully mitigate the detrimental effects of poor sleep quality on ADL and psychological distress.ConclusionsThe findings contribute to existing understanding by clarifying the fundamental mechanisms that link sleep quality and psychological distress. These results may provide a valuable reference to the Chinese government for improving mental health in older individuals.

Procrastinate at work, sleep badly at night: How job autonomy matters

AbstractDespite the well‐documented deleterious effects of poor sleep quality on procrastination, limited efforts have been devoted to examining whether procrastination can hurt sleep quality. To address this theoretical gap, this study aims to reveal how and when individuals' procrastination at work influences their subsequent sleep quality. Building upon cognitive appraisal theory, the current research employs experience‐sampling methodology to investigate mediators of rumination (as a cognitive pathway) and negative affect (as an affective pathway), explaining within‐person fluctuations in sleep quality resulting from daily procrastination. Furthermore, job autonomy is proposed to be a cross‐level moderator in the relationship between daily procrastination and rumination/negative affect. The results of 2026 daily data records from 213 employees across 10 consecutive workdays supported the mediation effect of rumination and moderation effects of job autonomy but did not support the mediation effect of negative affect. Specifically, daily procrastination was negatively related to subsequent sleep quality through the cognitive pathway of rumination. Our results also reveal that the positive relationships between daily procrastination and rumination/negative affect were stronger for employees with higher levels of job autonomy. Finally, we discuss the implications and limitations of this paper as well as future directions.

The Effect of Sleep Quality on Pain in Chilean Individuals with Musculoskeletal Disorders.

Poor sleep quality (SQ) negatively affects pain associated with musculoskeletal disorders (MSD). As the level of economic development of a country determines its sanitary conditions, these can influence the sleep–pain relationship; therefore, it is relevant to generate evidence in the population with MSD in developing countries. This cross-sectional study sought to determine the effect of poor SQ on pain in Chilean individuals with MSD, controlling for sex and duration of pain (in months). Method: A total of 228 individuals were included. SQ was measured with the Pittsburg Sleep Quality Index (PSQI), pain (intensity, interference and distress relative to pain) was measured with visual analog scales. Structural equation modeling (SEM) was performed to analyze the effect of SQ on pain. Results: A high frequency of poor SQ was present in the studied group, and was more prevalent in women. The SEM model evidenced that poor SQ predicts greater pain. Sex influences sleep quality and pain, but not pain duration. Conclusions: These findings indicate that poor SQ predicts higher pain in MSD and that women exhibit worse SQ and more significant pain than men. Our findings support that SQ should be considered in the comprehensive approach to pain in individuals with MSD.
