Purpose To contrast the associations of objectively measured moderate-to-vigorous physical activity (MVPA) and total accelerometer counts with biomarkers in a representative sample of U.S. adults.
Methods Data from the 2003 - 2006 NHANES were used for this analysis. The sample included adults ≥ 20 y, not pregnant or lactating, who had self-reported PA ...
Purpose The purpose of this study was to test if moderate to vigorous physical activity (MVPA) in less than the recommended ≥10-minute bouts related to weight outcomes.
Design Secondary data analysis.
Setting Random sample from the U.S. civilian noninstitutionalized population included in the National Health and Nutrition Examination Survey (...
Introduction Given its associations with morbidity and mortality, sedentary behaviour (SB) has emerged as a potentially significant public health issue. Although most studies of relationships between SB and health outcomes acknowledge that some sort of adjustment should be made for physical activity, there is no consensus on the approach for ...
Optimal sleep duration (7-8h), moderate-to-vigorous intensity physical activity
(MVPA) and light-intensity activity are beneficially associated with cardiometabolic
outcomes and related biomarkers, while sedentary time and long (≥9h) or short (<7h)
sleep duration are detrimentally associated.
Purpose This study examined whether sleep duration modified the relationship
between both sedentary/...
The pattern of physical activity in Hungarian adults might provide information on potential obesity prevention strategies. In preparation for a region assessment of physical activity (PA), placement of an activity monitor were studied in leu of the changes that the NHANES protocol has in the location of the ActiGraph monitors ...
Accelerometers offer valid and objective measures to assess free-living physical activity (PA) (Kodama et al, 2002; Lyden et al, 2012). While these devices provide rich information with frequent readings over a period of time, the large amount of data is difficult to analyze and special techniques to extract features are needed. Summarizing ...
OBJECTIVE: With the rise of type 2 diabetes in youth, it is critical to investigate factors such as physical activity (PA) and time spent sedentary that may be contributing to this public health problem. This article describes PA and sedentary time in a large cohort of youth with type 2 diabetes and ...
Purpose Examine whether nonbout physical activity (i.e., <10 minutes' duration of physical activity [PA]) demonstrates a stronger association with health outcomes than bout physical activity (i.e., ≥10 minutes' duration).
Design Cross-sectional study.
Setting NHANES 2003–2006.
Subjects A total of 6321 participants ranging in age from 18 to 85 years.
Measures Objectively measured PA ...
The purpose of this study was to examine the influence of child and adult cut-points on physical activity (PA) intensity, the prevalence of meeting PA guidelines, and association with selected health outcomes. Participants (6,578 adults ≥ 18 years, and 3,174 children and adolescents ≤ 17 years) from the National Health and Nutrition Examination Survey 2003-06 (Centers ...
Background Current research practice employs wide-ranging accelerometer wear time criteria to identify a valid day of physical activity (PA) measurement.
Objective To evaluate the effects of varying amounts of daily accelerometer wear time on PA data.
Methods A total of 1000 days of accelerometer data from 1000 participants (age=38.7±14.3 years; body mass ...
