Daily associations between sleep and stressors in nurses with and without children
This study examined whether the sleep-stress relationship is stronger for nurses with children than those without. During 14 days of ecological momentary assessment, 60 hospital nurses (24 parents) reported their previous night's sleep characteristics upon waking. Three times daily, they also reported whether they encountered any stressors and how severe those stressors were. Associations were assessed at the within- and between-person levels with parenting status as a between-person moderator. After controlling for covariates, previous night's poorer sleep quality, lower sleep sufficiency, and shorter time in bed were ass...

Multidimensional sleep health is associated with mental well-being in Australian adults

Association of job strain with accelerometer-based sleep duration and timing of sleep among older employees
This study examined the association of job strain with sleep duration, bedtimes and awakening times among public sector employees close to their retirement age. Differences in these sleep parameters between workdays and free days across job strain groups were examined. Duration and timing of sleep were measured repeatedly with accelerometers among 466 public sector employees in Finland (mean age 63 years, 86% women), who contributed to 759 measurements in total. Job demands (low/high) and control (low/high) measured by self-reports and job exposure matrix were used to identify low strain (low demand, high control), passive...

Sleep apnea severity based on estimated tidal volume and snoring features from tracheal signals
This study investigates the feasibility of estimating the severity of sleep apnea, as quantified by the apnea/hypopnea index (AHI), using the estimated tidal volume and snoring sounds extracted from tracheal signals. Tracheal signals were recorded simultaneously with polysomnography (PSG). The tidal volume was estimated from tracheal signals. The reductions in the tidal volume were detected as potential respiratory events. Additionally, features related to snoring sounds, which quantified variability, temporal clusters, and dominant frequency of snores, were extracted.

J Sleep Res. 2021 Sep 22:e13485. doi: 10.1111/jsr.13485. Online ahead of print.ABSTRACTSleep has been hypothesised to facilitate waste clearance from the brain. We aimed to determine whether sleep is associated with perivascular spaces on brain magnetic resonance imaging (MRI), a potential marker of impaired brain waste clearance, in a population-based cohort of middle-aged and elderly people. In 559 participants (mean [SD] age 62 [6] years, 52% women) from the population-based Rotterdam Study, we measured total sleep time, sleep onset latency, wake after sleep onset and sleep efficiency with actigraphy and polysomnography...

Effectiveness of an internet-based intervention to improve sleep difficulties in a culturally diverse sample of international students: A randomised controlled pilot study
J Sleep Res. 2021 Sep 22:e13493. doi: 10.1111/jsr.13493. Online ahead of print.ABSTRACTSleep difficulties are widespread among international students. Internet-based interventions are suggested as a low-threshold treatment option but may require cultural adaptation among culturally diverse populations. The present pilot study investigated the effectiveness and acceptance of an internet-based intervention to improve sleep difficulties in international students. A total of 81 international students of 36 nationalities were randomly assigned to the intervention (n = 41) or waitlist control group (n = 40). The intervention gro...

Test-retest reliability of the Epworth Sleepiness Scale in clinical trial settings
In conclusion, across three large clinical trials of participants with narcolepsy or obstructive sleep apnea, Epworth Sleepiness Scale scores demonstrated a robust acceptable level of test-retest reliability in evaluating treatment response over time.PMID:34545626 | DOI:10.1111/jsr.13476 (Source: Journal of Sleep Research)

Sleepy drivers on a slippery road: A pilot study using a driving simulator
J Sleep Res. 2021 Sep 19:e13488. doi: 10.1111/jsr.13488. Online ahead of print.ABSTRACTSleepy drivers have problems with keeping the vehicle within the lines, and might often need to apply a sudden or hard corrective steering wheel movement. Such movements, if they occur while driving on a slippery road, might increase the risk of ending off road due to the unforgiving nature of slippery roads. We tested this hypothesis. Twelve young men participated in a driving simulator experiment with two counterbalanced conditions; dry versus slippery road × day (alert) versus night (sleepy) driving. The participants drove 52.5 ...

Smartphone-based virtual agents and insomnia management: A proof-of-concept study for new methods of autonomous screening and management of insomnia symptoms in the general population
J Sleep Res. 2021 Sep 18:e13489. doi: 10.1111/jsr.13489. Online ahead of print.ABSTRACTInsomnia is the most frequent sleep disorder, and the COVID-19 crisis has massively increased its prevalence in the population, due to psychosocial stress or direct viral contamination. KANOPEE_2 is a smartphone-based application that provides interactions with a virtual agent to autonomously screen and alleviate insomnia symptoms through an intervention programme giving personalized advices regarding sleep hygiene, relaxation techniques and stimulus-control. In this proof-of-concept study, we tested the effects of KANOPEE_2 among users ...

Brain mitochondrial dysfunction and driving simulator performance in untreated obstructive sleep apnea
This study compared markers of brain energy metabolism in OSA patients identified as vulnerable vs resistant to driving impairment following extended wakefulness. 44 patients with moderate-severe OSA underwent 28hr extended wakefulness with three 90min driving simulation assessments. Using a two-step cluster analysis, objective driving data (steering deviation and crashes) from the 2nd driving assessment (22.5 h awake) was used to categorise patients into vulnerable (poor driving, n = 21) or resistant groups (good driving, n = 23). 1 H magnetic resonance spectra were acquired at baseline using two scan sequences (short ech...

Correlates of inadequate sleep health among primary school children
J Sleep Res. 2021 Sep 15:e13483. doi: 10.1111/jsr.13483. Online ahead of print.ABSTRACTThe aim of the present study was to explore potential factors of inadequate sleep health (i.e. sleep duration, quality, and timing) of school-aged children. Data were collected among 382 primary school children (aged 4-13 years) and their parents. Personal characteristics (i.e. age, sex), individual lifestyle behaviours (i.e. screen use, sleep hygiene behaviour), social and community factors (i.e. parental sleep-related practices, parental barriers, perceived ethnicity), and living conditions (i.e. parental educational level, sleep envir...
