Sedentary and Physical Activity Patterns in Adults with Intellectual Disability.

  • Published on Sep 7, 2017

Little is known about the patterns of sedentary time (ST) and physical activity (PA) levels throughout the week among adults and older adults with Intellectual Disability (ID). We analyzed ST and PA patterns of adults and older adults with ID. Forty-two adults and 42 older adults with mild to severe ID ...



Validity of treadmill- and track-based individual calibration methods for estimating free-living walking speed and VO2 using the Actigraph accelerometer

  • Published on Nov 25, 2015

Background: For many patients clinical prescription of walking will be beneficial to health and accelerometers can be used to monitor their walking intensity, frequency and duration over many days. Walking intensity should include establishment of individual specific accelerometer count, walking speed and energy expenditure (VO2) relationships and this can be ...


Regional sociocultural differences as important correlate of physical activity and sedentary behaviour in Swiss preschool children

  • Published on Dec 11, 2016

Question: Regional differences in physical activity in school-aged children and adults even within one country with the same political and health care system have been observed and could not be explained by sociodemographic or individual variables. We analysed whether such differences were already present in preschool children. Methods: Swiss children ...


Physical Activity, Sedentary Behavior, and Inflammatory and Hemostatic Markers in Men

  • Published on Mar 2017

Purpose: This study aimed to determine whether higher levels of physical activity (PA) and less sedentary behavior (SB) are associated with less inflammation, indicated by inflammatory and hemostatic biomarkers, in older men. Methods: A cross-sectional study of 1139 men, from the British Regional Heart Study (mean ± SD age = 78 ± 5 yr), and longitudinal ...



Objectively Measured Physical Activity and Mortality Risk Among American Adults

  • Published on Nov 2, 2016

Introduction: One major limitation of prior studies examining the influence of physical activity on mortality is use of self-reported measures. This study examined the association between objectively measured light physical activity (LPA) and moderate to vigorous physical activity (MVPA) and all-cause mortality. Methods: This study included 5,562 adults from the 2003–2006 National ...


Sedentary Time, Cardiorespiratory Fitness, and Cardiovascular Risk Factor Clustering in Older Adults–the Generation 100 Study

  • Published on Oct 2016

Objective: To determine whether meeting physical activity (PA) recommendations and/or having high age-specific cardiorespiratory fitness (CRF) attenuate the adverse effect of prolonged sedentary time on cardiovascular risk factor (CV-RF) clustering in older adults. Patients and Methods: We conducted a cross-sectional study of Norwegian women (495) and men (379) aged 70 to 77 years ...


Accelerometer-measured dose-response for physical activity, sedentary time, and mortality in US adults

  • Published on Oct 5, 2016

Background: Moderate-to-vigorous–intensity physical activity is recommended to maintain and improve health, but the mortality benefits of light activity and risk for sedentary time remain uncertain. Objectives: Using accelerometer-based measures, we 1) described the mortality dose-response for sedentary time and light- and moderate-to-vigorous–intensity activity using restricted cubic splines, and 2) estimated ...


Step-Based Physical Activity Metrics and Cardiometabolic Risk: NHANES 2005–2006

  • Published on Feb 2017

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 ...
