ABSTRACT Introduction: Within the prison environment, where strict surveillance and prompt decision-taking are essential to maintain security, poor sleep may be hazardous to correctional officers. This study aims to estimate the prevalence of and identify factors associated with severe sleep disorders in correctional officers. Material and Methods: An exploratory cross-sectional study comprised all correctional officers in a prison complex in Salvador city, Brazil. Information about sleep quality, sociodemographic and occupational aspects, lifestyle habits, and common mental disorders (self-reporting questionnaire-20 score ≥7 points) were collected via a self-administered questionnaire. Severe sleep disorder was defined as a score ≥31 points according to the mini sleep questionnaire. The measure of association used was the prevalence ratio (PR). Prevalence ratios were estimated by using a Cox multivariate regression model. The final adjusted model only included the variables that presented a prevalence ratio ≥1.20. Results: The prevalence of severe sleep disorders in the 374 correctional officers was 55.3%, and was strongly (prevalence ratio ≥1.20) associated with number of stressful activities at work (RPs=1.24, 1.19, and 1.17), number of attack and threat events against the correctional officers over the last 12 months (RPs showing gradient, 1.11, 1.24, and 1.41), common mental disorders (RP=2,24), and non-White skin color (RP=1,37). Conclusion: This study found high prevalence of severe sleep disorders in correctional officers, associated with impairment of their mental health, skin color, and, particularly, with situations of stress and violence at work. These factors must be taken into account when planning and providing health care to these workers.

ABSTRACT Objective: This study aimed firstly to describe sleep-related and mental health symptoms before and during the COVID-19 pandemic in a national-wide sample and, secondly, to verify attitudes towards help-seeking to treat these symptoms. Material and Methods: Data were collected through an online questionnaire sent through the Brazilian Sleep Association’s social media. The questionnaire included sociodemographic and sleep aspects questions currently and before the pandemic period. In addition, the survey addressed current and previous anxiety, depression, and burnout symptoms. The outcome help-seeking was addressed in the questionnaire as well by a single question asked when the participant reported mental or sleep problems. Results: The study covered 6,360 participants, mean age 43.5 years (SD=14.3), 76.7% female and 63.7% with undergraduate or higher degree filled out the survey. Seventy percent of participants reported sleep disturbances and 80% reported symptoms of anxiety during the pandemic. Help-seeking behavior was found only in one third of them. Hours of sleep reduced from 7.12 to 6.2h, which can be related with the increase in 28.2% of dissatisfaction with sleep duration during the pandemic. The highest frequency of complaints related to sleep was difficulty to fall asleep three or more times a week (going from 27.6% before the pandemic to 58.9% during the pandemic; p<0.001). Moreover, it was observed that help-seeking was more prevalent in men than women, and more in younger participants than in older ones. Conclusion: There was an increase of sleep and mental self-reported problems during the pandemic, which was not followed by help-seeking.

Study objectives This study investigated, through wrist actigraphy, the activity-rest pattern, estimate nocturnal sleep parameters, and quantify the exposure of light (daylight and blue light) during social isolation due to COVID-19. Methods The participants (n = 19, aged 19 - 33 years-old) wore the actigraph in nondominant wrist for 7 days. Derivation of 25 nocturnal sleep parameters was inferred from PIM mode raw data including sleep, wake, activity, and fragmentation statistics. A hierarchical cluster analysis determined the participants profiles. Mann-Whitney and independent Student t tests, linear stepwise regression and Kendalls test were applied. The significant level was a = 0.05. Results Two clusters were formed, normal sleepers (n = 13) and short sleepers (n = 6). The participants of both clusters went to sleep after midnight, spent approximately 1 h of being awake during time in bed, their latency to persistent sleep was normal, though true sleep minutes was less than 7 h, showed a normal sleep efficiency. Daytime activity was moderate, and a circadian rhythm was irregular. The regressions showed that bedtime and nocturnal activity contributed to the variance of daytime activity and the beginning of it (p< 0.001). The midpoint during the time in bed was the most significant predictor for the start of less period activity at night (p< 0.001). Conclusions Actigraphy inferred that during social isolation the individuals presented, despite normal sleep latency and efficiency, inconsistent sleep parameters and irregular circadian rhythm. Moreover, decreased exposure to daylight during the morning was observed.

BACKGROUND Menopausal period is one of the most critical stages of a womans life. Complications of the menopausal period including sleep disorders can affect the physical and mental state of women. As sleep disorder has a determinant role in the quality of life, this study was conducted to evaluate postmenopausal womens quality of sleep and its related factors. Material and Methods This cross-sectional-analytical study was conducted on 323 postmenopausal women based on convenience and consecutive sampling. The data-gathering tool consisted of two parts; sociodemographic characteristics and the Pittsburgh Sleep Quality Index (PSQI). Data analysis was performed using descriptive and inferential statistical tests at a significance level of p<0.05. Results Sleep disorder was determined in 49.9% of participants. The mean PSQI score was 5.32 ± 3.881. There was a significant correlation between PSQI and age (ß = 0.29, p < 0.001) indicating that sleep disorder increased with an increase in age. There was a significant correlation between body mass index (ß = 0.599, p < 0.001) and undesired sleep quality. Conclusions Regarding the presence of sleep disorder in almost half of the study participants, and the relationship between sleep quality and body mass index and age, it is recommended that decision and policymakers design educational consultation interventions to improve the quality and quantity of sleep in menopause women.
绝经期是女性一生中最关键的阶段之一。包括睡眠障碍在内的更年期并发症会影响女性的身心状态。由于睡眠障碍对生活质量具有决定性作用，本研究旨在评估绝经后妇女的睡眠质量及其相关因素。材料与方法采用方便、连续抽样的方法，对323名绝经后妇女进行横断面分析研究。数据收集工具由两部分组成;社会人口学特征和匹兹堡睡眠质量指数(PSQI)。数据分析采用描述性和推断性统计检验，p<0.05。结果49.9%的参与者存在睡眠障碍。PSQI平均评分为5.32±3.881。PSQI与年龄有显著的相关性(ß = 0.29, p < 0.001)，表明睡眠障碍随着年龄的增加而增加。体重指数与不良睡眠质量之间存在显著相关性(ß = 0.599, p < 0.001)。结论针对近一半的研究参与者存在睡眠障碍，以及睡眠质量与体重指数和年龄之间的关系，建议决策者设计教育咨询干预措施，以改善更年期妇女的睡眠质量和数量。

Athlete chronotype has been documented to underpin diurnal variations in skill execution across various team sports. However, no research has explored the effects of athlete chronotype on basketball-specific skills at different times of the day. Therefore, the aim of this study was to explore diurnal variations in basketball shooting accuracy according to chronotype. Professional, male basketball players (n = 13) completed a Morningness- Eveningness Questionnaire and were categorised into chronotypes using a tertile split technique (morning-types: n = 4; neither-types: n = 4; evening-types: n = 5). Players completed separate trials of a shooting accuracy test in the morning (08:00-09:30h) and afternoon (15:00-16:30h) with each trial consisting of 20 shots attempted from four court locations at either two- or three-point distances and one-shot location from the free-throw line (100 shots in total). Each shot attempt was scored using a 0-3-point scale with higher scores awarded to more accurate shots. Non-significant ( p >0.05) differences in shooting scores were evident between morning and afternoon trials for each chronotype group, with small-large effects in shooting scores favouring the morning across groups. Moreover, non-significant ( p >0.05) differences in shooting scores were apparent between chronotype groups in the morning ( small-large effects) and afternoon ( moderate-large effects). Shooting accuracy appears to remain consistent across morning and afternoon performances irrespective of player chronotype in a professional basketball team, suggesting coaches may not need to schedule training sessions involving shooting tasks at specific times of the day to optimise shooting accuracy in players.

Objective In the general population, co-morbid insomnia and sleep apnoea (COMISA) is associated with higher risk of cardiovascular diseases (CVD). However, despite a high prevalence of COMISA in type 2 diabetics, no study has investigated its potential implication in the negative cardiovascular outcome of this particular subpopulation. The aim of this study was therefore to examine the risk of CVD associated with COMISA in type 2 diabetics. Methods Data from 471 type 2 diabetics recruited from the clinical database of the Erasme Hospital sleep laboratory were analysed. Only type 2 diabetics with SCORE index ≥5% were included in the group at high risk of CVD. Logistic regression analyses were conducted to examine the risk of CVD associated with COMISA in type 2 diabetics. Results A high risk of CVD was present in 32.9% of type 2 diabetics. After adjustment for the main confounding factors associated with cardiovascular risk, multivariate logistic regression analysis revealed that unlike obstructive sleep apnoea syndrome or insomnia alone, only COMISA was associated with higher risk of CVD in type 2 diabetics. Discussion In our study, we have demonstrated that unlike its components alone, only COMISA was associated with higher risk of CVD in type 2 diabetics, which highlights the importance of the central role played by the negative synergistic effect of COMISA on the cardiovascular outcome in this particular subpopulation. Thus, given these elements, more systematic research and adequate therapeutic management of COMISA seem to be necessary to allow better cardiovascular prevention in type 2 diabetics.

Objective Physiological networks have recently been employed as an alternative to analyze the interaction of the human body. Within this option, different systems are analyzed as nodes inside a communication network as well how information fows. Several studies have been proposed to study sleep subjects with the help of the Granger causality computation over electroencephalographic and heart rate variability signals. However, following this methodology, novel approximations for children subjects are presented here, where comparison between adult and children sleep is followed through the obtained connectivities. Methods Data from ten adults and children were retrospectively extracted from polysomnography records. Database was extracted from people suspected of having sleep disorders who participated in a previous study. Connectivity was computed based on Granger causality, according to preprocessing of similar studies in this feld. A comparison for adults and children groups with a chi-square test was followed, employing the results of the Granger causality measures. Results Results show that differences were mainly established for nodes inside the brain network connectivity. Additionally, for interactions between brain and heart networks, it was brought to light that children physiology sends more information from heart to brain nodes compared to the adults group. Discussion This study represents a frst sight to children sleep analysis, employing the Granger causality computation. It contributes to understand sleep in children employing measurements from physiological signals. Preliminary fndings suggest more interactions inside the brain network for children group compared to adults group.

A comparison for adults and children groups with a chi-square test was followed, employing the results of the Granger causality measures. Results Results show that differences were mainly established for nodes inside the brain network connectivity. Additionally, for interactions between brain and heart networks, it was brought to light that children physiology sends more information from heart to brain nodes compared to the adults group. Discussion This study represents a frst sight to children sleep analysis, employing the Granger causality computation. It contributes to understand sleep in children employing measurements from physiological signals. Preliminary fndings suggest more interactions inside the brain network for children group compared to adults group.","PeriodicalId":21848,"journal":{"name":"Sleep Science","volume":"374 1","pages":"215 - 223"},"PeriodicalIF":1.6,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75123613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obstructive sleep apnoea (OSA) is the major underlying co-morbidity in many of the non-communicable diseases (NCD) due to obesity as a common risk factor. Incidence and prevalence of OSA is on the constant rise ever since this entity came to forefront three decades ago. Precise treatment of underlying OSA is extremely important in major NCDs like diabetes mellitus, hypertension, endocrine disorders and vascular diseases. OSA is subcategorized in to mild, moderate and severe based of apnoea-hypopnea index (AHI). Based on the severity grading, treatment of OSA ranges from life style modifications to oral appliances, continuous positive airway pressure (CPAP) and surgeries. AHI system of severity grading in OSA has several inherent shortcomings and using AHI system for severity grading as the holy grail is likely to be counter-productive. AHI system equates apnoea and hypopnea as equal events, whereas physiological effects vary significantly. AHI system does not account duration of apnoea or body position during apnoeic events. We discuss at length the pitfalls of AHI system of severity grading in OSA.

ABSTRACT Introduction: Bedtime procrastination is the deliberate delay of the time an individual goes to bed in the absence of external reasons. The COVID-19 pandemic has pushed families to establish new routines and ways of managing newfound roles and responsibilities. This scenario is likely to exacerbate bedtime procrastination due to, for example, a challenge in balancing professional and personal life. Objective: The aim is to present preliminary findings regarding bedtime procrastination and its relation to sociodemographic characteristics, sleep routines, perceived daily fatigue, dinnertime, and activities performed near bedtime, during the second lockdown in Portugal. Material and Methods: A cross-sectional online survey was conducted with a sample of 560 adults. Results: During home confinement, most people (79.46%) delayed their bedtime. However, this delay does not seem to be affecting the number of hours of sleep, as 88.60% were sleeping the recommended or appropriate number of hours. Nevertheless, most of the participants reported feeling tired throughout the day (53.04%), and individuals who reported to have procrastinated their sleep are those who reported more tiredness ( r pb =.33, p <.01). Additionally, bedtime procrastination is positively associated with findings related to dinnertime (e.g., dinner between 9 p.m. and 10 p.m., r pb =.19, p<.01) and with engagement in activities near bedtime (e.g., studying/working, r pb =.39, p <.01). Conclusion: Current data shows relationships between bedtime procrastination and most of the studied variables. Specifically, findings indicate that lack of routines, especially scheduled nighttime routines (e.g., studying/working near bedtime), may have contributed to bedtime procrastination during the second lockdown in Portugal.
