Abstract: Recent interest in sedentary behavior and technological advances expanded use of watch-size accelerometers for continuous monitoring of physical activity (PA) over extended periods (e.g., 24 h/day for 1 week) in studies conducted in natural living environment. This approach necessitates the development of new methods separating bedtime rest and activity ...
Abstract: Wrist actigraphy is commonly used to measure sleep, and hip actigraphy is commonly used to measure activity. It is unclear whether hip-based actigraphy can be used to measure sleep. This study assessed the validity of wrist actigraphy and hip actigraphy compared to polysomnography (PSG) for the measurement of sleep. 108 ...

Background: Little is known about physical activity and sedentary behavior of adults with bipolar disorder (BP). Physical activity and sedentary behaviors may be modifiable factors associated with elevated rates of obesity, diabetes, cardiovascular disease, metabolic syndrome, and mortality in adults with BP. Methods: Sixty adult outpatients treated for BP (> 18 yr) ...
Background: Childhood obesity is an epidemic. Strategies are needed to promote children’s healthy habits related to diet and physical activity. School gardens have the potential to bolster children’s physical activity and reduce time spent in sedentary activity; however little research has examined the effect of gardens on children’...
