Association between chronotype, social jetlag, sleep quality, and academic burnout among nursing students: A cross-sectional study

ABSTRACT Academic burnout in nursing students is a serious problem worldwide that results in emotional exhaustion, cynicism and low professional efficacy. The aim of the current study was to examine the association between sleep quality and circadian rhythm indicators and academic burnout among Iranian nursing students. This cross-sectional study was conducted on 325 undergraduate nursing students studying at Qazvin University of Medical Sciences between November and February 2023. Data collection was carried out using self-report questionnaires including demographic characteristics, The Pittsburgh Sleep Quality Index (PSQI), reduced-Morningness-Eveningness Questionnaire (r-MEQ), and the Maslach Burnout Inventory-Student Survey (MBI-SS). Social jetlag (SJL) was defined as the absolute value of the difference between the midpoint of sleep on free days (MSF) and the midpoint of sleep on workdays (MSW). Data were analyzed using univariate and multivariate linear regression models. About 31.4% of participants had evening chronotype and almost half of them suffered from poor sleep quality. About 47.7% of the participants had SJL ≥ 2 h. In the multivariate linear regression model, students with evening chronotype compared to morning chronotype experienced more academic burnout in emotional exhaustion, cynicism and professional efficacy. PSQI score was only correlated with emotional exhaustion and cynicism subscales. Increased SJL was a predictor on all three subscales of academic burnout. The findings suggested that evening chronotype, poor sleep quality, and high SJL were associated with increased likelihood of academic burnout in nursing students. Assessment of circadian preference and sleep quality is beneficial for timely identification and prevention of academic burnout in nursing students.

Late Bedtime and Altered Diurnal Axial Length Rhythms of the Eye.

Affecting one-third of the population worldwide and increasing, the sight-threatening condition myopia is causing a significant socio-economic burden. To better understand its etiology, recent studies investigated the role of ocular and systemic rhythms, yet results are conflicting. Here we profiled 24-h variations of axial length of the eye and salivary melatonin concentration in young adults with and without myopia and explored the potential impacts of bedtime on these rhythms. A total of 25 healthy young adults (age 25.0 ± 4.8 years, 13 females) completed this study, including 13 myopes (mean spherical equivalent refractive error -2.93 ± 1.46 diopters) and 12 non-myopes (0.14 ± 0.42 diopters). Saliva sample collection and axial length measurements were repeated for seven times over 24 h starting from 8 am. Information on sleep and chronotype was collected at first visit with the Pittsburgh Sleep Quality Index and the Morningness-Eveningness Questionnaire. Significant diurnal rhythms of axial length and salivary melatonin concentration were identified in both refractive groups (both p < 0.001), with no myopia-related rhythm difference (interaction of measurement time-point × myopia, p = 0.9). Late bedtime was associated with altered rhythms (p = 0.009) and smaller diurnal change (p = 0.01) in axial length. Elevated melatonin levels were observed in myopes (p = 0.006) and in late sleepers (p = 0.017). These findings suggest that sleep/wake cycles may be involved in the regulation of axial length rhythms. Further research is needed to determine if there exists a causal relationship between the two.

Gender-specific association between snoring and total sleep duration with type 2 diabetes mellitus in rural adults.

To investigate the separate and joint association between snoring and total sleep duration with the risk of type 2 diabetes mellitus (T2DM) in both genders within Chinese rural community. The Henan Rural Cohort Study included a total of 28093 participants. Data on snoring and total sleep duration were obtained through the Pittsburgh Sleep Quality Index (PSQI). Binary logistic regression was employed to assess the correlation between snoring and total sleep duration with T2DM. The prevalences of T2DM were 8.53% in males and 9.27% in females. Males exhibited a higher prevalence of snoring (34.90%) compared to females (22.42%), and the median of total sleep duration was also longer in males (8.83h) than in females (8.67h), respectively (P < 0.001). Females who snored had an adjusted odds ratio (OR) and 95% confidence interval (CI) for T2DM of 1.19 (1.06, 1.35) when contrasted with non-snorers. Compared with optimal total sleep duration (6-8h), longer total sleep duration (≥ 8h) increased the prevalence of T2DM by 17% (95%CI: 3%, 32%) in females. Additionally, the participants with shorter total sleep duration (< 6h) and snoring have the highest risk of T2DM, with an increase of 91% (95%CI: 20%, 204%) than those with optimal total sleep duration and non-snorers in females. These significant associations were not found in males. Snoring and longer total sleep duration independently elevated the prevalence of T2DM. Meantime, a synergistic relationship was observed between snoring and total sleep duration with a higher prevalence of T2DM. These associations exhibited gender-specific differences.

Sleep disturbances based on patient reported outcomes in patients with breast cancer.

Sleep disturbances are common in patients with breast cancer, but comprehensive evaluations with patient-reported outcomes (PRO) and sleep evaluation with polysomnography (PSG) are lacking. This study describes sleep disruption using PROs and PSG to identify underlying sleep disorders. A retrospective review of patients with breast cancer undergoing formal sleep evaluation from 4/1/2009 to 7/31/2014 was performed. Clinical characteristics, PROs using Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS), and PSG data were reviewed. 404 patients were identified with 43% early, 30% locally advanced and 17% metastatic disease. PSQI revealed poor sleep in 75%, and ESS demonstrated daytime sleepiness in 55%. Sleep aid use was reported by 39%, and pain medication use in 22%. Most patients (50.2%) had multiple sleep disorders. Insomnia (54.5%) was the most frequent sleep disorder, followed closely by obstructive sleep apnea (OSA) (53.7%). PSG was performed in 74%. Multivariate analysis linked poor sleep to use of sleep aids [OR 7.7, 95% CI 3.9 to 15.2], anxiety disorder [OR 4.8, 95% CI 1.7 to 14.0], and metastatic disease [OR 2.8, 95% CI 1.1 to 6.6]. Daytime sleepiness correlated with known diagnosis of OSA [OR 1.9, 95% CI 1.0 to 3.3] and sleep aid use [OR 0.6, 95% CI 0.4 to 0.9]. Poor sleep was associated with sleep aid use, anxiety disorder and metastatic disease. Insomnia was the most common sleep disorder, followed by OSA (mostly mild). Education about sleep health and proactive screening for sleep symptoms would be beneficial in patients with breast cancer.

Sex Differences in the Role of Sleep on Cognition in Older Adults

Abstract Study Objectives The study aimed to investigate sex differences in the relationship between sleep quality (self-report and objective) and cognitive function across three domains (executive function, verbal memory, and attention) in older adults. Methods We analyzed cross-sectional data from 207 participants with normal cognition or mild cognitive impairment (89 males and 118 females) aged over 60. The relationship between sleep quality and cognitive performance was estimated using generalized additive models. Objective sleep was measured with the GT9X Link Actigraph, and self-reported sleep was measured with the Pittsburgh Sleep Quality Index. Results We found that females exhibited lower executive function with increased objective total sleep time, with a steeper decline in performance after 400 minutes (p = 0.015). Additionally, longer objective sleep correlated with lower verbal memory linearly (p = 0.046). In males, a positive linear relationship emerged between objective sleep efficiency and executive function (p = 0.036). Self-reported sleep was not associated with cognitive performance in females and males with normal cognition. However, in males with cognitive impairment, there was a non-linear positive relationship between self-reported sleep and executive function (p &amp;lt; 0.001). Conclusions Our findings suggest that the association between sleep parameters on cognition varies between older males and females, with executive function being most strongly associated with objective sleep for both sexesTop of Form. Interventions targeting sleep quality to mitigate cognitive decline in older adults may need to be tailored according to sex, with distinct approaches for males and females.

Understanding the impact of the pandemic on university students: Changes in sleep, eating patterns, and psychological well-being

BACKGROUND: Covid-19 is one of the world’s major pandemics. It has affected millions of people in various ways. OBJECTIVE: This study investigates the influence of pandemic-induced shifts in eating and sleeping behaviors on the psychological well-being of university students. METHODS: The study adopted a cross-sectional research design. A total of 604 students participated in the study. The Personal Form, the Psychological Well-Being Index, and the Pittsburgh Sleep Quality Index were used to collect data. The research was conducted between October 2021 and December 2022. RESULTS: The participants reported a mean psychological well-being score of 40.76±9.38, alongside a Pittsburgh Sleep Quality Index score of 7.46±3.30. Analysis revealed a significant negative correlation between the mean psychological well-being scores and the Pittsburgh Sleep Quality Index scores (p &lt; 0.01). Throughout the pandemic, the participants experienced a decline in physical activity, an increase in their body weight, and a change in their eating habits. While psychological well-being remained relatively high, sleep quality was notably poor. Notably, improvements in psychological well-being corresponded with enhancements in sleep quality, suggesting a reciprocal relationship between the two variables. CONCLUSIONS: The pandemic negatively impacted the physical activity and body weight of young adults. This study highlights the importance of promoting physical activity among university students during pandemics and similar crises to reduce adverse effects on body weight. It also highlights the importance of educating students about the importance of healthy sleep and how to maintain good sleep hygiene.

Cross-Cultural Adaptation and Psychometric Evaluation of the Brazilian Portuguese Version of the Nocturia Quality-of-Life Questionnaire.

The objective was to cross-culturally adapt and check for the reliability, internal consistency, and validity of the Nocturia Quality of Life Questionnaire (N-QoL) in Brazilian Portuguese (N-QoL-Br). The questionnaire was translated according to international guidelines, included forward-translation, back-translation, and consensus among an expert committee. Participants with nocturia completed the Pittsburgh Sleep Quality Index, International Consultation on Incontinence Questionnaire Overactive Bladder, and the General Quality of Life Assessment Questionnaire SF-36 (Medical Outcomes Study 36-Item Short-Form Health Survey), in addition to the N-QoL-Br. The Brazilian version was applied in men and women with nocturia twice within a range of 4weeks. Psychometric properties such as content validity, construct validity, internal consistency, and test-retest reliability were tested. Content validity was considered adequate. Eighty-four men and women participated in the study. Good internal consistency in the domains and final score of the N-QoL-Br was observed, with Cronbach α greater than 0.9. The test-retest reliability was also high, with an intraclass correlation coefficient greater than 0.9 for the domain sleep/energy, bother/concern, and total score (0.98, 0.98, and 0.97 respectively). The Portuguese version of the N-QoL-Br presents good internal consistency and reproducibility and it can be considered adequate and valid for evaluating the impact of nocturia on the quality of life of men and women in the Brazilian population.

Pittsburgh Sleep Quality Index (PSQI) Changes in Virologically Suppressed People Living with HIVSwitching to Long-Acting Cabotegravir and Rilpivirine

Background: Limited evidence is available about sleep quality changes associated with the use of Cabotegravir (CAB), a new, long-acting (LA) antiretroviral (ARV) drug belonging to the class of Integrase Strand Transfer Inhibitors (INSTIs). Methods: Pittsburgh Sleep Quality Index (PSQI) was calculated in 53 people living with HIV (PLWH) under the care of the outpatient services of two Italian Infectious Diseases Centers in Apuliabefore (M0) and seven months after (M7) the switch to LA CAB. Global scores and relative subitems were compared using paired sample tests. The same analysis was repeated in subgroups of PLWH switching from INSTIs-, Dolutegravir-(DTG), and Bictegravir (BIC)-based regimens. Results: A significant reduction was reported in global mean (±StandardDeviation, SD) PSQI at M7 compared to M0 (4 (±3) vs. 3 (±2), p = 0.01), particularly in the areas of sleep latency and sleep disturbances. The improvement was also significant in PLWH already on INSTIs- (from median 3 to 2 points, p = 0.02) and DTG-based (from median 4 to 2, p = 0.01) ARV regimens, but not among those who switched from BIC-based regimens. Conclusions: PLWH reported improved sleep quality after switching from ARV treatment to LA CAB. Further studies are needed to give deeper insights into this phenomenon.

Variations in objectively measured sleep parameters in patients with different premature ejaculation syndromes.

Poor sleep quality is now a cause of sexual dysfunction. To investigate variations in sleep quality among patients with different types of premature ejaculation (PE) and a control group. Patients with PE were categorized into groups according to 4 types: lifelong (LPE), acquired (APE), variable (VPE), and subjective (SPE). Basic demographic information about the participants was first collected, and then clinical data were obtained. Outcomes included the 5-item International Index of Erectile Function, Premature Ejaculation Diagnostic Tool, 7-item Generalized Anxiety Disorder, 9-item Patient Health Questionnaire, Pittsburgh Sleep Quality Index, self-estimated intravaginal ejaculation latency time (minutes), and sleep monitoring parameters obtained from a wearable device (Fitbit Charge 2). A total of 215 participants were enrolled in the study, of which 136 patients with PE were distributed as follows: LPE (31.62%), APE (42.65%), VPE (10.29%), and SPE (15.44%). Subjective scales showed that patients with APE were accompanied by a higher prevalence of erectile dysfunction, anxiety, and depression, as well as poorer sleep quality (assessed by the Pittsburgh Sleep Quality Index). The results of objective sleep parameters revealed that average durations of sleep onset latency (minutes) and wake after sleep onset (minutes) in patients with APE (mean ± SD; 20.03 ± 9.14, 55 ± 23.15) were significantly higher than those with LPE (15.07 ± 5.19, 45.09 ± 20.14), VPE (13.64 ± 3.73, 38.14 ± 11.53), and SPE (14.81 ± 4.33, 42.86 ± 13.14) and the control group (12.48 ± 3.45, 37.14 ± 15.01; P < .05). The average duration of rapid eye movement (REM; minutes) in patients with APE (71.34 ± 23.18) was significantly lower than that in patients with LPE (79.67 ± 21.53), VPE (85.93 ± 6.93), and SPE (80.86 ± 13.04) and the control group (86.56 ± 11.93; P < .05). Similarly, when compared with the control group, patients with LPE had significantly longer durations of sleep onset latency and wake after sleep onset and a significantly shorter duration of REM sleep. Our study suggests that clinicians should pay attention not only to male physical assessment but also to mental health and sleep quality. This study suggests that changes in sleep structure occur in patients with PE, which may provide some direction for future research. However, the cross-sectional study design does not allow us to conclude that sleep is a risk factor for PE. After controlling for traditional parameters such as age, erectile dysfunction, anxiety, and depression, sleep parameters are independently associated with PE. Patients with APE and LPE show significant alterations in sleep parameters, with patients with APE having notably poorer sleep quality, whereas patients with VPE and SPE have sleep parameters similar to controls.

Hubungan Kualitas Tidur dengan Derajat Keparahan Acne Vulgaris pada Siswa-Siswi Kelas X di Sma Muhammadiyah 2 Bandar Lampung Provinsi Lampung Tahun 2024

Acne vulgaris is a multifactorial chronic skin condition, characterized by inflammation in the pilosebaceous units, such as the formation of comedones, papules, pustules, nodules, and cysts, which typically present on the face, upper body, and upper arms. Sleep quality is defined by an individual's capacity to sleep adequately and achieve the necessary amount of rest. This study aims to identify the correlation between sleep quality and the severity of acne vulgaris among tenth grade students at Muhammadiyah 2 Senior High School of Bandar Lampung, Lampung Province in 2024.The research adopts a quantitative approach and analytical survey method with a cross-sectional design. The study population includes all 285 tenth-grade students at Muhammadiyah 2 Senior High School of Bandar Lampung, Lampung Province in 2024. A total of 74 respondents were selected using the Slovin formula based on inclusion and exclusion criteria, with a purposive sampling technique. The data were collected using the Pittsburgh Sleep Quality Index (PSQI) questionnaire and observations of the severity of acne vulgaris. Data analysis was conducted using univariate and bivariate analyses with the non-parametric chi- square test, utilizing SPSS version 26.The study revealed that 50 respondents (67.6%) had poor sleep quality, while 24 respondents (32.4%) experienced a moderate severity of acne vulgaris. The analysis indicates a significant correlation between sleep quality and the severity of acne vulgaris among tenth-grade students at Muhammadiyah 2 Senior High School in Bandar Lampung, Lampung Province in 2024, with a p-value of 0.000 ≤ 0.05. The results of this research provide useful information and may serve as a supplementary resource for future research.

A closer look at depression and sleep quality relation: A cross-sectional study of taxi drivers in Tabriz metropolis.

Taxi drivers play a significant role in urban mobility and safety as professional drivers. They typically have poor incomes, long work hours, lack of sleep, and high levels of stress, which increase the risk of physical and mental illnesses. The goal of this study was to explore the relationship between sleep disorders and depression among Tabriz metropolis taxi drivers. Using the street intercept technique, a cross-sectional study was conducted with the participation of 402 taxi drivers in Tabriz during January and March 2020. Data collection tools included the Pittsburgh Sleep Quality Index (PSQI) and Patient Health Questionnaire as well as demographic information. Twenty taxi stops were used as sampling sites, and the method used was random sampling based on the number of drivers at each stop. Statistical analysis was performed using Stata 13. The majority of drivers worked an average of 6 days each week, with a mean tenure of 13.3 years. The sleep quality mean score for drivers was 5 (SD = 2.3). Approximately, 21% of them had sleep disorder (PSQI >6). Moderate depression was recognized in 13% of drivers and moderately severe depression has been found in 5% of them. Drivers were more likely to experience sleep disorders if they had mild (odds ratio [OR] = 3.9), moderate (OR = 16.4), or fairly severe depression symptoms (OR = 35.3). A seven times higher risk of depression was identified among drivers with sleep disorders. It might be contended that a mutual relationship has been found between sleep disorders and depression, and disregarding this will deteriorate sleep turbulences. Considering the pivotal role of taxi drivers in urban mobility, accommodating initiatives that give a break time for drivers and improve their mental health is recommended.

Sleep quality and perceived stress levels in Chinese patients with minor recurrent aphthous stomatitis: a cross-sectional questionnaire-based survey

ABSTRACT Objectives This cross-sectional study aimed to evaluate sleep quality and perceived stress levels in Chinese patients with active minor recurrent aphthous stomatitis (MiRAS) lesions, as well as to investigate the potential relationship between sleep quality and perceived stress levels and the risk of MiRAS episodes. Methods The study population consisted of individuals recruited from a Chinese cohort who underwent medical and oral examinations from March 2022 to August 2023. All participants completed a set of uniform anonymous questionnaires, which included sociodemographic characteristics, clinical information, the Pittsburgh Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI) and the Perceived Stress Scale (PSS-14). Statistical analysis was conducted using the independent sample t test, Mann-Whitney U test, Pearson’s chi-square test and Pearson’s correlation analysis. After adjusting for potential confounders (age, gender, marital status, and education level), multivariate logistic regression analyses were performed to assess the associations of sleep quality and perceived stress levels with the risk of MiRAS episodes. Additionally, restricted cubic spline curves were constructed to visualize these correlations. Results A total of 329 eligible volunteers participated in the study, comprising 122 Chinese MiRAS patients and 207 healthy controls without MiRAS. Compared to healthy participants, MiRAS patients exhibited significantly higher PSQI and ISI scores (p = 0.000). However, no statistically significant difference was observed between the two groups regarding PSS-14 scores or its two subscales (p > 0.05). Multiple regression analysis indicated that lower sleep quality was significantly associated with an increased risk of MiRAS episodes (p = 0.000), whereas no statistically significant relationship was found between perceived stress levels and the risk of MiRAS episodes (p > 0.05). Conclusion Maintaining a regular bedtime and improving sleep quality may contribute to reducing the incidence and recurrence of MiRAS, while psychological intervention may be ineffective for MiRAS patients.

Comparison of sleep quality, diet quality, and weight change between COVID-19-recovered patients and healthy controls: A matched case-control study.

Literature suggests that individuals who have recovered from COVID-19 may experience post-COVID conditions, including sleep problems and alterations in smell or taste. Thus, this study aims to compare the sleep quality, diet quality, and weight change between COVID-19-recovered patients and healthy controls. A matched case-control study involving young adults aged 18-30 years was conducted in the Klang Valley of Malaysia. The young adults were matched in a 1:1 ratio based on their sociodemographic characteristics, including gender, age, marital status, ethnicity, educational attainment, employment status, and monthly earned income. The Pittsburgh Sleep Quality Index was utilized to evaluate sleep quality, and the Diet Quality for Malaysia was used to determine the diet quality of all young adults. The young adults retrospectively recalled their prepandemic body weight in February 2020, while their current body weight in February 2023 was measured using a TANITA HD-314 digital weighing scale. Emerging findings suggest that sleep quality and weight change were comparable between COVID-19-recovered patients and healthy controls. However, healthy controls were reported to have a more diversified diet than COVID-19-recovered patients. Nevertheless, no significant main effects or interaction effects of sleep and diet quality on weight change were observed in COVID-19-recovered patients or healthy controls. In this study, young adults also reported suffering from sleep deprivation and deficiency due to the pandemic. Intervention programs that emphasize avoiding stimulants before bedtime for healthy controls, promoting the importance of having a diversified and balanced diet among the COVID-19-recovered patients, and achieving an ideal body weight for all young adults should be conducted after the COVID-19 pandemic.

Factors associated with sleep quality among Afghan healthcare workers.

Sleep is a complex physiological process during which the body and mind enter a period of rest. For a healthy lifestyle, different cohort groups can be affected in different ways. One such cohort is healthcare workers (HCWs)-an unexplored group in Afghanistan. Therefore, the present study examined the association between a range of sociodemographic factors including having night shift work and sleep quality among Afghan HCWs. A cross-sectional survey was administered in January 2023 among HCWs (N = 342) in the Herat province of Afghanistan. The survey examined sleep quality and its association with a range of sociodemographic factors among HCWs. Logistic regression models were used to examine the association of sleep quality with sociodemographic characteristics among HCWs. The Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality among HCWs. A total of 342 HCWs participated in the present study with an age range of 18 to 60 years. The mean age of the participants was 28.90 years (SD ± 8.10). Just over half of the participants were male (50.3%). Of the 342 participants, 58.5% reported poor sleep quality. Being married status, having higher number of children, not being a doctor, having low economic status, working night shifts, and having a traumatic event occur during past month were among the main variables associated with sleep quality among Afghan HCWs. Multiple regression analysis indicated that having high income [negatively] (AOR = 4.132, p = 0.002), working night shifts [positively] (AOR = 0.288, p < 0.001), and having a traumatic event occur during past month [positively] (AOR = 0.504, p = 0.007) were significantly associated with sleep quality. The study suggests the need for Afghan health employers to create a healthy work environment that prioritizes the well-being of their employees by limiting overtime hours, providing rest breaks during long shifts, and ensuring that HCWs have access to necessary resources for coping with work-related stressors. These policies would promote the overall health and well-being of the workforce and would likely lead to better patient care outcomes.

Exploration of sleep quality and rest-activity rhythms characteristics in Bilateral Vestibulopathy patients.

Sleep and circadian timing systems are constantly regulated by both photic and non-photic signals. Connections between the vestibular nuclei and the biological clock raise the question of the effect of peripheral vestibular loss on daily rhythms, such as the sleep-wake cycle and circadian rhythm. To answer this question, we compared the sleep and rest-activity rhythm parameters of 15 patients with bilateral vestibulopathy (BVP) to those of 15 healthy controls. Sleep and rest-activity cycle were recorded by a device coupling actimetry with the heart rate and actigraphy at home over 7 days. Subjective sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Sleep efficiency and subjective sleep quality were significantly reduced, and sleep fragmentation was increased in BVP patients compared to controls. BVP patients displayed a damped amplitude of the rest-activity rhythm and higher sleep fragmentation, reflected by a higher nocturnal activity compared to controls. These results suggest that both rest-activity and sleep cycles are impaired in BVP patients compared to healthy controls. BVP patients seem to have greater difficulty maintaining good sleep at night compared to controls. BVP pathology appears to affect the sleep-wake cycle and disturb the circadian rhythm synchronization. Nevertheless, these results need further investigation to be confirmed, particularly with larger sample sizes.

Social Media Addiction and its Association with Sleep Quality Among Medical Students in A Medical College In Tamil Nadu, India

Background: Medical students' social media addiction disrupts and lowers sleep quality, hurting their everyday life and academic performance, stressing the need for effective ways to promote their well-being and achievement. The study aims to estimate the prevalence of social media addiction and to find out the association with sleep quality among medical students in private medical college. Methodology: A cross-sectional study involving 792 MBBS students from a private medical college in Chengalpattu district, Tamil Nadu, utilized the Bergen Social Media Addiction Scale (BSMAS) to assess social media addiction and the Pittsburgh Sleep Quality Index (PSQI) to evaluate sleep quality. Data were collected through a pre-tested semi-structured questionnaire and analysed using SPSS version 25. Results: The study revealed a 17.7% prevalence of social media addiction among medical students, significantly associated with poor sleep quality, female gender, and morning social media use. Other factors included dependence on social media for updates, more than three hours of daily use, eye discomfort, Snapchat use, compulsion to post at least six photos and subjective sleep quality, sleep latency, duration, disturbances, use of sleeping medication, and Daytime dysfunction. Conclusions: Research demonstrates a significant correlation between social media addiction and poor sleep quality among medical students, highlighting the need for focused interventions and awareness activities to counteract its harmful influence.

Sleep Deprivation and Sleep Quality of Healthcare Shift Workers in Bangladesh

Shift work is an essential feature of industrialized society. Our present study was aimed at investigating the sleep deprivation and sleep quality of the healthcare shift workers in Bangladesh. In investigating so, we took 462 healthcare shift workers from five districts of Bangladesh. Among them 152 were male and 310 were female. The participants ranged from 19 to 65 years of age. We took the participants on the basis of convenience sampling technique from 30 hospitals and medical centers. To collect data we administered Bangla version of Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). Findings of our study revealed that sleep deprivation and shifts were marginally dependent (χ2 = 11.56, p = 0.07). However, sleep quality had been found independent of shifts (χ2 = 4.31, p = 0.12). Shift-wise analyses yielded that sleep deprivation was high (μ = 7.56) and sleep quality was worse (μ = 3.78) in rotating shift workers in comparison to fixed and regular shift workers. Sleep quality was found better outside of metropolitan city (t = -3.258, p&lt;0.01). Findings have been discussed in terms of previous findings and contemporary theories. Recommendations are proposed in the light of our findings in conclusion. Dhaka Univ. J. Biol. Sci. 33(2): 67-75, 2024 (July)

Poor Sleep Quality is associated with Decreased Regional Brain Glucose Metabolism in Healthy Middle-aged Adults

Sleep disturbance is associated with the development of neurodegenerative disease. We aimed to address the effects of sleep quality on brain glucose metabolism measured by 18F-Fl uorodeoxyglucose (18F-FDG) positron emission tomography (PET) in healthy middle-aged adults. A total of 378 healthy men (mean age: 42.8±3.6 years) were included in this study. Participants underwent brain 18F-FDG PET and completed the Korean version of the Pittsburgh Sleep Quality Index (PSQI-K). Additionally, anthropometric measurements were obtained. PETs were spatially normalized to MNI space using PET templates from SPM5 with PMOD. The Automated Anatomical Labeling 2 atlas was used to define regions of interest (ROIs). The mean uptake of each ROI was scaled to the mean of the global cortical uptake of each individual and defined as the standardized uptake value ratio (SUVR). After the logarithmic transformation of the regional SUVR, the effects of the PSQI-K on the regional SUVR were investigated using Bayesian hierarchical modeling. Brain glucose metabolism of the posterior cingulate, precuneus, and thalamus showed a negative association with total PSQI-K scores in the Bayesian model ROI-based analysis. Voxel-based analysis using statistical parametric mapping revealed a negative association between the total PSQI-K scores and brain glucose metabolism of the precuneus, postcentral gyrus, posterior cingulate, and thalamus. Poor sleep quality is negatively associated with brain glucose metabolism in the precuneus, posterior cingulate, and thalamus. Therefore, the importance of sleep should not be overlooked, even in healthy middle-aged adults.

An examination of sleep problems and parental well-being, comparing families with and without autistic children

BackgroundSleep problems are a common comorbidity in autistic children and adolescents. Little is known about the role of sleep problems in parental well-being in the context of autism. MethodThe current study utilised actigraphy and questionnaire-based measures in mothers of autistic children and adolescents (n = 11), and mothers of typically developing (TD) children and adolescents (n = 11). Actigraphy is an objective, non-intrusive method for examining sleep. It involves wearing a wristwatch-like microcomputer that records motion. Measures included the Pittsburgh Sleep Quality Index, Autoimmune Disease in Family Members Questionnaire, Parenting Stress Index-Short Form, World Health Organization Quality of Life Abbreviated Version (WHOQOL-BREF), Hospital Anxiety and Depression Scale, and the Multidimensional Scale of Perceived Social Support. ResultsMothers of autistic children had significantly greater difficulties with subjective sleep quality, sleep duration, sleep efficiency, and daytime dysfunction, than mothers of TD children. In mothers of autistic children, parental use of sleep medication on the PSQI was positively associated with objective sleep onset latency using actigraphy, with a large effect size. Families with an autistic child had significantly more family members with osteoarthritis and rheumatoid arthritis than did families of TD children. Families of autistic children had significantly more autistic family members than did families of TD children. ConclusionsMothers of autistic children had significantly higher levels of stress, anxiety, depression, and lower levels of quality of life and perceived social support, than parents of TD children. Sleep problems identified via actigraphy were associated with parental stress, anxiety and depression, and quality of life.

The Influence of Mindfulness-Based Counseling on Sleep Quality Women with a History of COVID-19 in Pregnancy

Background: During the COVID-19 outbreak, certain populations, including pregnant women, were particularly vulnerable. This increased susceptibility could lead to postnatal complications, including sleep disorders, which are common in the postpartum period. Objectives: To determine the effect of mindfulness-based counseling on sleep quality in women with a history of COVID-19 during pregnancy. Methods: This quasi-experimental study utilized a pre- and post-consultation design and included 100 women with a history of COVID-19 during pregnancy. Using convenience sampling, participants were randomly assigned to either an intervention group or a control group. Data were collected through a demographic questionnaire and the Pittsburgh Sleep Quality Index. The intervention group received eight weekly mindfulness-based counseling sessions, each lasting 45 minutes, conducted via social messenger by the researcher. Outcomes were assessed eight weeks after the final counseling session. Results: The two study groups were comparable in terms of demographic characteristics. In the intervention group, mean sleep quality scores improved from 7.28 ± 0.99 at the beginning to 4.28 ± 0.79 at the end of the study (95%CI: 2.18 to 3.81, MD = 3, P = 0.002). In the control group, scores changed from 6.94 ± 0.84 to 6.76 ± 0.71 (95%CI: - 0.20 to 0.33, MD = 0.18, P = 0.820). Comparing the groups after counseling, the intervention group had a mean sleep quality score of 4.28 ± 0.79, while the control group had 6.76 ± 0.71 (95%CI: 1.68 to 3.31, MD = 2.50, P &lt; 0.001). Conclusions: Mindfulness-based counseling positively affected sleep quality in the intervention group. Utilizing existing social networking platforms for such interventions can effectively improve sleep quality in women.
