Objectives To compare the extent to which different combinations of objectively measured sedentary behavior (SB) and physical activity contribute to cardiometabolic health. Design and Methods A population representative sample of 5,268 individuals, aged 20-85 years, was included from the combined 2003-2006 NHANES datasets. Activity categories were created on the combined basis ...
Background Sedentary behavior is related to obesity, but measures of sedentary behaviors are lacking for adults. The purpose of this study was to examine the reliability and validity of the Sedentary Behavior Questionnaire (SBQ) among overweight adults. Methods Participants were 49 adults for the 2 week test-retest reliability study (67% female, 53% white, mean ...
Background Chronic musculoskeletal pain (CMP) may be associated with cardiovascular disease (CVD). This study aimed to investigate the association between CMP and CVD, and the contribution of physical activity and sedentary behaviour to any association. Methods We performed a secondary analysis of 3332 middle-aged (45-64 years) and 2022 older (65+ years) adults included ...
This study describes moderate to vigorous physical activity (MVPA) and sedentary behavior among New York City (NYC) residents 60 years and older and compare to national United States' estimates. Adults aged 60 or older living in NYC (n=760) were compared to similar aged adults from the National Health and Nutrition Examination Survey (...
In order to make robust conclusions regarding the association between accelerometer-measured sedentary time and overweight and obesity among children, several gaps in the literature must be addressed. The purpose of this study was to examine associations between sedentary time, weekday sedentary time, weekend sedentary time, sedentary bouts, sedentary breaks, and ...
Objectives This study aimed to evaluate the feasibility of using a compact elliptical device to increase energy expenditure during sedentary activities. A secondary aim was to evaluate if two accelerometers attached to the elliptical device could provide reliable and valid assessments of participants' frequency and duration of elliptical device use ...
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 To examine the association between objectively measured light-intensity and moderate-to-vigorous-intensity physical activity (MVPA), sedentary behaviors, and biological markers in a national sample of U.S. pregnant women, as few studies have examined these relationships among this population. Methods The sample of noninstitutionalized U.S. civilians was selected by a ...
Objectives To determine the ActiGraph GT3X+ cut-points with the highest accuracy for estimating time spent in sedentary behaviour in older adults in free-living environments. ActivPAL3™ was used as the reference standard. Design Cross-sectional study. Methods 37 participants (13 males and 24 females, 73.5±7.3 years old) wore an ActiGraph GT3X+ and an ActivPAL3™ ...
Background There is currently no validated questionnaire available to assess total sedentary time in older adults. Most studies only used TV viewing time as an indicator of sedentary time. The first aim of our study was to investigate the self-reported time spent by older persons on a set of sedentary ...
