Background:
Research suggests that accumulating moderate to vigorous physical activity (MVPA) in longer continuous bouts may have beneficial effects on metabolic syndrome risk factors. The objective of this study was to examine the independent associations of MVPA bout patterns on metabolic syndrome risk factors among a nationally representative sample of ...
Abstract: The new 2018 Physical Activity Guidelines for Americans provides updated recommendations for physical activity behavior. These guidelines remove the requirement for physical activity to be obtained in bouts of at least 10min. The purpose of the present study was to provide an updated estimate of the proportion of adults meeting ...
Introduction: The objective of this study was to compare the associations of accelerometer-derived total activity counts per day and minutes of bouted moderate to vigorous physical activity (MVPA) with insulin resistance.
Methods: The sample included 2,394 adults (aged ≥20 y) from the 2003–2006 National Health and Nutrition Examination Survey. Time spent in MVPA, ...
Objective:
To investigate associations between self-reported and objectively measured physical activity, sedentary behavior and overweight/obesity based on percent body fat measured with Dual Energy X-Ray Absorptiometry (DXA), waist circumference (WC), waist-to-height ratio and body mass index, focusing on different intensities and domains of physical activity.
Methods:
Data from NHANES 2003–2006 ...
Purpose: This study aimed to catalog the relationships between step-based accelerometer metrics indicative of physical activity volume (steps per day, adjusted to a pedometer scale), intensity (mean steps per minute from the highest, not necessarily consecutive, minutes in a day; peak 30-min cadence), and sedentary behavior (percent time at zero ...
Background: Accelerometers provide an objective assessment of physical activity and are frequently deployed for at least multiple days. However, it is unclear how to summarize multiple days into one overall physical activity estimate, particularly in the presence of missing data. This study compared summarization method prediction and precision, and the ...
We will present the results of analysis of physical activity data collected with accelerometers on 10000+ subjects in National Health and Nutrition Examination Survey (NHANES), a nationally representative sample of the US population. The data have been analyzed with recently developed multilevel functional data analysis approaches that focus on modeling variability ...
Objective: No study has comprehensively examined the independent and combined effects of sensory impairment, physical activity and balance on mortality risk, which was this study’s purpose.
Methods: Data from the population-based 2003–2004 National Health and Nutrition Examination Survey (NHANES) was used, with follow-up through 2011. Physical activity was assessed via accelerometry. ...
Background Psoriasis confers risk for cardiometabolic disorders. Cardiorespiratory fitness is inversely associated with risk of cardiometabolic disorders in other populations, but limited data have been published assessing cardiorespiratory fitness among individuals with psoriasis. This investigation aimed to: 1) assess cardiorespiratory fitness among individuals with psoriasis in the general population; and 2) compare ...
Background: Applying latent class analysis (LCA) to accelerometry can help elucidated underlying patterns. This study described the patterns of accelerometer-determined sedentary behavior and physical activity among youth by applying LCA to a nationally representative United States (US) sample.
Methods: Using 2003–2006 National Health and Nutrition Examination Survey data, 3998 youths 6–17 years wore ...
