Purpose: Increasing physical activity (PA) may be an important non-pharmacological approach to improve sleep quality but it is not clear how level and timing and co-current light exposure influence sleep quality. PA time outdoors may be more beneficial for sleep, but only recently has it been possible to measure sleep, ...
Background: Physical function is an important factor for health and well-being of older adults. Performance-based measures of physical function have been related to an elevated risk of frailty, disability, and mortality. Poor sleep quality has been associated with reduced physical function in older adults. However, little is known about the ...
Background: Sleep and physical activity are both important for executive function; however, few cognitive function studies include comprehensive measurement of both of these behaviors. Understanding how physical activity impacts the associations between sleep and executive function in older women is especially pertinent given the high prevalence of sleep disturbances and ...
Purpose: Moderate-to-vigorous physical activity (MVPA) and sleep behaviors have been independently associated with increased risk for hypertension (HTN), the leading risk factor for stroke and heart disease. However, these behaviors may be synergistic in contributing to HTN. The purpose of this study was to examine the odds of hypertension diagnosis (...
Abstract: Sleep and sedentary and active behaviors are linked to cardiovascular disease risk biomarkers, and across a 24-hour day, increasing time in 1 behavior requires decreasing time in another. We explored associations of reallocating time to sleep, sedentary behavior, or active behaviors with biomarkers. Data (n = 2,185 full sample; n = 923 fasting subanalyses) ...
Background & Aims More than 50% of patients with chronic hepatitis C with only mild liver disease complain about chronic fatigue, daytime sleepiness and poor sleep quality. The aim of the present study was to characterize and objectify the sleep disturbances in hepatitis C virus-infected patients. Methods Twenty-five women who had ...
Background Physical activity (PA), sedentary behaviour (SB), sleep and diet have all been associated with increased risk for chronic disease. Seasonality is often overlooked as a determinant of these behaviours in adults. Currently, no study has simultaneously monitored these behaviours in UK adults to assess seasonal variation. Aim The present ...
Background Adequate sleep is a critical factor for adolescent’s health and health-related behaviors Objective (a) to describe sleep duration in European adolescents from nine countries, (b) to assess the association of short sleep duration with excess adiposity and (c) to elucidate if physical activity (PA), sedentary behaviors and/or ...
Background Understanding fluctuations in lifestyle indicators is important to identify relevant time periods to intervene in order to promote a healthy lifestyle; however, objective assessment of multiple lifestyle indicators has never been done using a repeated-measures design. The primary aim was, therefore, to examine between-season and within-week variation in physical ...
Study Objectives The majority of adolescent sleep research has utilized self-reported sleep duration and some have based information on a solitary question. Whilst some have claimed to have validated sleep survey data with objective actigraphy measures in adolescents, the statistical approach applied only demonstrates the strength of the association between ...
