Abstract Sleep disruption is common in patients in the intensive care unit (ICU). The aim of the study was to measure sound levels during sleep-protected time in the ICU, determine sources of sound, assess the impact of sound levels and patient-related factors on duration and quality of patients' sleep. The study was performed between 2018 and 2019. A commercially available smartphone application was used to measure ambient sound levels. Sleep duration was measured using the Patient's Sleep Behaviour Observational Tool. Sleep quality was assessed using the Richards-Campbell Sleep Questionnaire (RCSQ). The study population comprised 18 (58%) men and 13 (42%) women. There were numerous sources of sound. The median duration of sleep was 5 (IQR 3.5–5.7) hours. The median score on the RCSQ was 49 (IQR 28–71) out of 100 points. Sound levels were negatively correlated with sleep duration. The cut-off peak sound level, above which sleep duration was shorter than mean sleep duration in the cohort, was 57.9 dB. Simple smartphone applications can be useful to estimate sound levels in the ICU. There are numerous sources of sound in the ICU. Individual units should identify and eliminate their own sources of sound. Sources of sound producing peak sound levels above 57.9 dB may lead to shorter sleep and should be eliminated from the ICU environment. The sound levels had no effect on sleep quality.

The main purpose of the present study was to explore the associations of sleep duration and sleep quality with self-rated health. In this cross-sectional study, participants were 894 elderly individuals. Self-rated health, sleep duration, and sleep quality were self-reported. The associations were examined using multiple logistic regression analyses.After adjusting for sex, physical activity, smoking consumption, alcohol consumption, psychological distress, socioeconomic status, and chronic disease/s, sleeping <6 h (OR (Odds ratio) = 3.21; 95% CI (95 percent confident interval) 1.61 to 6.39), 6–7 h (OR = 2.47; 95% CI 1.40 to 4.36), 8–9 h (OR = 3.26; 95% CI 1.82 to 5.83), and >9 h (OR = 3.62; 95% CI 1.57 to 8.34) and having ‘poor’ sleep quality (≥5 points; OR = 2.33; 95% CI 1.46 to 3.73) were associated with ‘poor’ self-rated health. When sleep duration and sleep quality were entered simultaneously into the model, the same associations remained. Our findings provide evidence that both ‘short’ and ‘long’ sleep and ‘poor’ sleep quality are associated with ‘poor’ self-rated health. Thus, interventions that promote healthy sleep hygiene in the elderly are warranted.

The main purpose of the study was to explore the associations of sleep duration and sleep quality with physical activity (PA). In this cross-sectional study, participants were 894 elderly individuals (mean age 80 ± 3 years; 56.0% women) living in nursing homes. PA, sleep duration, and sleep quality (based on the Pittsburgh Sleep Quality Index (PSQI)) were self-reported. The associations of sleep duration and sleep quality with PA at the nursing home level were analyzed using generalized estimating equations with clustering. Participants reporting short sleep duration (<6 h; OR = 0.45; 95% CI 0.25–0.80) were less likely to report sufficient PA, yet those reporting long sleep duration (>9 h; OR = 2.61; 95% CI 1.35–5.02) and good sleep quality (<5 points; OR = 1.59; 95% CI 1.19–2.12) were more likely to report sufficient PA. When sleep duration and sleep quality were entered into the same model, the same associations remained. This study shows that elderly individuals who report short sleep duration are less likely to meet PA guidelines, while those who report long sleep duration and good sleep quality are more likely to meet PA guidelines. Strategies aiming to improve sleep duration and sleep quality are warranted.

The aim of this study was to systematically examine the literature on physical activity and sleep in non-clinical and population-based settings. The inclusion criteria were original studies testing the association between physical activity (as exposure) and sleep (as outcome) in representative samples of the general population, workers, or undergraduate students. Sleep health included sleep duration, sleep quality and insomnia. Studies evaluating samples including only individuals with some disease or a health condition were excluded. A search was performed in the PubMed, Scopus, Lilacs, CINAHL, and SPORTdiscus databases in March 2018. Data extraction was performed using the following items: year, author, country, population, age group, sample size, study design, sleep measurement/definition, physical activity measurement/definition, adjustment and main results. A total of 57 studies were selected, which markedly used heterogeneous instruments to measure physical activity and sleep. The majority were conducted in high-income countries and with cross-sectional design. Physical activity was associated with lower odds of insomnia (observed in 10 of 17 studies), poor sleep quality (observed in 12 of 19 studies) and long sleep duration (observed in 7 of 11 studies). The results about short sleep or continuous sleep duration remain unclear. Physical activity seems to be associated with sleep quality and insomnia, especially among adult and elderly populations in which these outcomes are more usually measured. The short- and long-term effects of physical activity intensities and dose-response on sleep should be better evaluated.

Background: The afoot COVID-19 pandemic has covered approximately every edge of the world. Schools and colleges are temporarily shut leading to children being indoors. Thus, gadgets have become an inseparable part of life and govern the daily routine of an individual. The aim of the study was to assess the pattern of gadget usage and sleep quality among medical undergraduates during COVID-19 lockdown.Methods: Present cross-sectional study was conducted amongst 149 medical undergraduates of Shri Vasantrao Naik Govt. Medical College, Yavatmal. Their gadget usage pattern and sleep quality before and during lockdown were measured using a predesigned and pretested questionnaire based on Smartphone addiction scale-short version (SAS-SV) and Pittsburgh sleep quality index (PSQI), administered via the Google forms platform.Results: 139 (93.28%) responses were completely and correctly filled. Smartphone addiction was seen in 71 (51.08%) study subjects. The mean sleep duration before and during lockdown had no significant changes. There was linear positive correlation between SAS-SV score and PSQI score, but the correlation was not statistically significant.Conclusions: The proportion of smartphone addiction amongst medical undergraduates is significantly high and the mean sleep duration is reduced during lockdown.

IntroductionCardiovascular disease is the leading cause of on-duty fatalities among U.S. firefighters. Research has demonstrated that many modifiable risk factors are contributors to the high prevalence of cardiometabolic risk factors. The current study aimed to assess whether sleep is associated with cardiometabolic risk factors among Indianapolis firefighters. The findings could support improving sleep hygiene in this population.Material and MethodsThis cross-sectional study was conducted from the baseline data of eligible firefighters enrolled in “Feeding America’s Bravest”, a Mediterranean diet lifestyle intervention within the Indiana Fire Departments. Participants’ sleep quality was categorized as “good” (≤ 8 points) or “bad” (&gt;8 points) by a sleep quality questionnaire based on some questions from Pittsburgh Sleep Quality Index. In addition, firefighters’ sleep duration was stratified based on the number of hours slept per night (≤6 as “short sleep” or &gt;6 hours as normal). Linear and logistic regression models were used to examine the association of sleep with cardiometabolic risk factors.ResultsA total of 258 firefighters were included. Bad sleepers had higher weight, greater waist circumference, higher body mass index (BMI), and increased body fat (all p&lt;0.01) compared to good sleepers. Similarly, participants with short sleep duration were heavier (p&lt;0.02), had greater BMI (p&lt;0.02) and increased body fat (p&lt;0.04) compared with participants with normal sleep duration. Both bad and short sleepers had a higher prevalence of hypertension and obesity (p &lt;0.05).ConclusionsOur study supports that both sleep quality and quantity are associated with cardiometabolic risk among firefighters.

Abstract Background In order to study the high blood pressure of children and adolescents and its influencing factors, it provides evidence-based evidence for the high blood pressure prevention of primary and secondary school students. Methods This study is a cross-sectional survey, which uses stratified cluster sampling method to select students from 7 schools to participate in questionnaire survey and physical examination. The correlation between single factor and high blood pressure was analyzed by chi-square test, and multivariate logistic regression analysis was used for multivariate analysis. Results A total of 1,814 subjects, including 512 primary school students (28.22%), 499 junior high school students (27.51%), 563 senior high school (31.04%), and 240 vocational high school (13.23%). There were 1000 males (55.13%) and 814 females (44.70%). The average age was 13.64±2.65 years. The detection rate of high blood pressure was 9.76%. Multivariate logistic regression analysis showed that the age groups were 10~ and 14~ (OR=20.870, 95%CI=2.372-183.666; OR=10.049, 95%CI=1.306-77.353) , sleep duration < 7h (OR=4.136, 95%CI=4.136), and physical education class times ≤2 times per week (OR=5.073, 95%CI=2.497-10.306), which were risk factors for high blood pressure in children and adolescents. Normal weight and overweight group were protective factors compared to the obesity group (OR=0.094, 95%CI=0.061-0.146; OR=0.225, 95%CI=0.134-0.378). Conclusion The age groups of 14~ and 16~ years old, physical education classes ≤ 2 times per week, and sleep duration <7h were risk factors for primary and secondary school students, and BMI of Normal weight and overweight group were protective factors compared to the obesity group students.

Objective: To determine the prevalence of sleep quality in the elderly within our outpatient department.Material and Method: A cross-sectional study was conducted by; calculating the sample size for a survey with ‘proportion to size’ at the outpatient department of Songklanagarind Hospital from; October to November, 2015. A total of 408 participants aged between 65 and 99 were interviewed. Demographic and sleep-related data were collected. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) – Thai version. The results were analyzed in terms of descriptive statistics and conducted using R-Epicalc and R-Survey software.Results: Our subjects were predominantly married females. The proportion of those in the 65-74 age range was 63.0%.Most of the participants (70.8%) were poor sleepers, with mean and median PSQI scores of 7.7 and 7.0, respectively.Regarding poor sleepers, their problems were; short sleep duration (99.7%), poor sleep efficiency (61.6%) and daytime dysfunction (51.6%).Conclusion: Similarly to previous studies, our findings showed a high prevalence of poor sleep quality in the elderlypopulation. A sleep duration of less than 6 hours was the major problem in the poor sleeper group. Gaining a betterinsight into sleep quality correlating with comorbidities is recommended.
