Introduction: Night-to-night variability of sleep variables derived from actigraphy or sleep diary data appears to be a novel risk factor associated with physical and mental health. However, little is known about factors associated with night-to-night sleep variability. The aim of this study was to assess the association of sociodemographic and ...
Introduction: Lower levels of regular physical activity are an independent risk factor for insomnia incidence and prevalence. The impact of public health initiatives to increase physical activity on sleep outcomes of people with chronic sleep disorders remains mainly unexplored. The present trial was designed to investigate the effects on sleep ...
Purpose: Seasonal variations in weight gain among children are well documented. Urban minority and overweight youth are at higher risk for weight gain during the summer months, which may result from decreases in physical activity (PA) and sleep. While research has established links between PA, sleep, and BMI, the current ...
Purpose: To identify cross-sectional and seasonal sleeping and physical activity (PA) patterns in a community-dwelling Icelandic healthy aging population using accelerometers. Methods: Participants (n=244, male/female 110/134, age 79.7±4.9 years, BMI 26.9±4.8 kg/m2) wore an Actiwatch Spectrum on the non-dominant wrist to assess sleep and an Actigraph GT3X on the right ...
Purpose: The purpose of this study was to examine the correlation between parent and adolescent levels of physical activity, sedentary behaviors, and sleep among a group of overweight and obese adolescents. Methods: Baseline data of parent-adolescent pairs who enrolled in an E-health lifestyle modification intervention were analyzed for this paper (...
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) ...
