Objective:
Examine the association between sedentary behavior and psychiatric symptoms among overweight and obese adults with schizophrenia or schizoaffective disorders (SZO/SA).
Design:
Randomized clinical trial; Weight Assessment and Intervention in Schizophrenia Treatment (WAIST) Study: baseline data collected 2005-2008.
Setting:
University of Pittsburgh Medical Center, Pittsburgh, PA, USA.
Participants:
Community-dwelling ...
Study design:
Cross-sectional validation study.
Objectives:
The goals of this study were to validate the use of accelerometers by means of multiple linear models (MLMs) to estimate the O2 consumption (VO2) in paraplegic persons and to determine the best placement for accelerometers on the human body.
Setting:
Non-hospitalized paraplegics’ community.
...
Introduction:
Laboratory-based polysomnograpy (PSG) is the gold standard technique for assessment and quantification of sleep. Wrist and hip actigraphy have been widely used to quantify sleep and physical activity, respectively. It remains unclear whether hip actigraphy is also a valid measure of sleep.
Purpose: To compare sleep varialbes simultaneously derived ...
Introduction:
Elevated C-reactive protein (CRP) is associated with adverse pregnancy outcomes. In non-pregnant populations, physical activity has been inversely associated with CRP, but this association has not been evaluated during pregnancy. The purpose of this study was to evaluate the association between objectively measured physical activity, sedentary behavior, and CRP ...
Accelerometers could potentially be used to assess physical activity and sleep using the same monitor; however, two different positions are typically used for the assessment of physical activity and sleep (waist and wrist, respectively). The aim of this study is to evaluate the concordance between wrist- and waist-worn Actigraphs for ...
Objectives:
To measure sleep duration in 7-year-old children; identify the determinants of sleep duration; and assess the association between short sleep duration and obesity, cognitive functioning, and behaviour. Design: Longitudinal study with disproportionate sampling of the participants.
Setting:
Community.
Participants:
591 seven-year-old children, of whom 519 had complete sleep data.
Interventions:
Not ...
Purpose:
To assess correlates of physical activity, and to examine the relationship between physical activity and physical functioning, in 160 older (66 ± 6 years old), overweight/obese (mean body mass index = 33.5 ± 3.8 kg/m2), sedentary (less than 30 mins of activity, 3 days a week) individuals with knee osteoarthritis.
Methods:
Physical activity was measured with accelerometers ...
Background:
Military veterans provide a large and diverse population to examine the extent to which compulsory physical activity (PA) in early adulthood is associated with PA later in life.
Methods:
We assessed self-reported and objectively measured PA and sedentary time in the 900 veterans and 2036 nonveterans with valid data from the 2003–2006 ...
Background:
To provide more accurate assessment of commuting behavior and potential health effect, it is important to have accurate methods. Therefore, the current study aimed to a) compare questionnaire reported mode of commuting with objectively measured data from accelerometer and cycle computer, b) compare moderate vigorous physical activity (MVPA) among ...
Background:
Physical activity (PA) and related energy
expenditure (EE) is often assessed by means of a single
technique. Because of inherent limitations, single techniques
may not allow for an accurate assessment both PA and related
EE. The aim of this study was to develop a model to accurately
assess common ...
