Standardised criteria for classifying the International Classification of Activities for Time-use Statistics (ICATUS) activity groups into sleep, sedentary behaviour, and physical activity

Globally, the International Classification of Activities for Time-Use Statistics (ICATUS) is one of the most widely used time-use classifications to identify time spent in various activities. Comprehensive 24-...

This study examines the contribution of HRB and their effects on multisystem biological risk associated with morbidity and early mortality. We systematically reviewed the literature to assess the links between HRB and AL. Twenty-six eligible human studies were included in our assessment of the current literature investigating the association of different HRB that included overeating/obesity, alcohol, smoking, drug use, physical inactivity and sleep impairments in relation to AL. We found that 50% of obesity and substance abuse, 75% of sleep and 62.5% of combined HRB studies showed a significant association with AL. Lifesty...

Publication date: Available online 14 December 2019Source: NeuroscienceAuthor(s): M. Panagiotou, T. DeboerAbstractDim-light-at-night (DLAN) exposure is associated with health problems, such as metabolic disruptions, immunological modulations, oxidative stress, sleep problems, and altered circadian timing. Neurophysiological parameters, including sleep patterns, are altered in the course of aging in a similar way. Here, we investigated the effect of chronic (three months) DLAN exposure (12L:12Dim-light, 75:5lux) on sleep and the sleep electroencephalogram (EEG), and rest-activity behavior in young (6-month-old, n=9) and age...

Publication date: Available online 14 December 2019Source: NeuroscienceAuthor(s): Andrey Kostin, Md. Aftab Alam, Jerome M. Siegel, Dennis McGinty, Md. Noor AlamAbstractAging is a well-recognized risk factor for sleep disruption. The adverse effects of aging on sleep include sleep disruption by frequent awakenings, a decline in both non-rapid eye movement (nonREM) and REM sleep amounts, and a weaker homeostatic response to sleep loss. Evidence also suggests that sleep in females is more sensitive to changes in the ovarian steroidal milieu. The Fischer-344 rats are commonly used experimental subjects in various behavioral an...

Publication date: Available online 14 December 2019Source: Neurobiology of StressAuthor(s): Annalisa M. Baratta, Nickole R. Kanyuch, Casey A. Cole, Homayoun Valafar, Jessica Deslauriers, Ana PocivavsekAbstractThe kynurenine pathway (KP) is the dominant pathway for tryptophan degradation in the mammalian body and emerging evidence suggests that acute episodes of sleep deprivation (SD) disrupt tryptophan metabolism via the KP. Increases in the neuroactive KP metabolite kynurenic acid (KYNA) during pregnancy may lead to a higher risk for disrupted neurodevelopment in the offspring. As pregnancy is a critical period during whi...

Publication date: June 2020Source: Current Opinion in Behavioral Sciences, Volume 33Author(s): Lauren N Whitehurst, Pin-Chun Chen, Mohsen Naji, Sara C MednickOver the last 100 years there has been a proliferation of research into the mechanisms of sleep that support cognition. Majority of these studies point to electroencephalographic features during sleep that are linked to plasticity and support valuable cognitive skills, like long-term memory. Importantly, sleep is both a central and an autonomic phenomenon with dynamic shifts occurring in both the brain and the body at sleep onset and throughout a sleep period. Prior w...

Publication date: June 2020Source: Current Opinion in Behavioral Sciences, Volume 33Author(s): Marion Baillet, Christina SchmidtIncreasing evidence suggests an association between typical age-related changes in sleep and brain structure. Here we review studies exploring the association between human histo-pathological and in vivo neuroimaging markers of brain structure and sleep-wake parameters in healthy older adults. Evidence from both large-scale epidemiological studies and in-lab quantification of specific sleep signatures are reviewed and advantages and pitfalls highlighted. Overall, the results point to an associatio...
