Accelerometer-based physical activity and sedentary behavior assessment in Brazilian military firefighters: the Brasilia Firefighters Study – BFS

  • Presented on Oct. 2017

Introduction: Firefighting is known to be a high cardiovascular risky activity, involving elevated physical and psychological demands. We hypothesized that during a routine 24-hour on-duty period firefighters combine physical activities of different intensities/durations with long periods of sedentary behavior. Purpose: To evaluate the physical activity level (PAL) and sedentary ...

Associations of Accelerometer-Measured and Self-Reported Sedentary Time With Leukocyte Telomere Length in Older Women

  • Published on Feb 1, 2017

Few studies have assessed the association of sedentary time with leukocyte telomere length (LTL). In a cross-sectional study conducted in 2012–2013, we examined associations of accelerometer-measured and self-reported sedentary time with LTL in a sample of 1,481 older white and African-American women from the Women's Health Initiative and determined whether associations ...

Sedentary Behavior, Cadence, and Physical Activity Outcomes after Knee Arthroplasty

  • Published on Jan 2017

Purpose: This study comprehensively examined sedentary behavior and physical activity patterns in people with severe knee osteoarthritis awaiting total knee arthroplasty (TKA) and in individuals after TKA. Methods: Preoperative (n = 32, mean ± SD = 69.9 ± 5.3 yr) and 1-yr postoperative participants with TKA (n = 38, 67.9 ± 7.3 yr) wore ActiGraph GT3X+ activity monitors ...

Comparison of Sedentary Estimates between activPAL and Hip- and Wrist-Worn ActiGraph.

  • Published on Aug 2016

Purpose: Sedentary behavior is an emerging independent health risk factor. The accuracy of measuring sedentary time using accelerometers may depend on the wear location. This study in older adults evaluated the accuracy of various hip- and wrist-worn ActiGraph accelerometer cutoff points to define sedentary time using the activPAL as the ...

Changes in Physical Activity and Function with Transition to Retirement Living: A Pilot Study

  • Published on Dec 2016

This pilot study examined changes in physical activity and function among older adults moving from community dwellings to retirement living. Twelve community-dwelling older adults, recruited from the wait-lists of two retirement living facilities, were assessed prior to and following the transition to retirement living. Physical activity was assessed using an ...

Proportion of children meeting recommendations for 24-hour movement guidelines and associations with adiposity in a 12-country study

  • Published on Nov 25, 2016

Backgrounds: The Canadian 24-h movement guidelines were developed with the hope of improving health and future health outcomes in children and youth. The purpose of this study was to evaluate adherence to the 3 recommendations most strongly associated with health outcomes in new 24-h movement guidelines and their relationship with adiposity (...

Intra-individual variability in day-to-day and month-to-month measurements of physical activity and sedentary behaviour at work and in leisure-time among Danish adults

  • Published on Dec 3, 2016

Background: Accelerometers can obtain precise measurements of movements during the day. However, the individual activity pattern varies from day-to-day and there is limited evidence on measurement days needed to obtain sufficient reliability. The aim of this study was to examine variability in accelerometer derived data on sedentary behaviour and physical ...

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 and Changes in Adiposity in the Transition from Elementary to Middle School

  • Published on Feb 1, 2017

Objectives: This study examined the longitudinal associations of objectively measured physical activity, sedentary behavior, and diet quality with two measures of adiposity and a measure of weight status. Methods: A total of 658 children from 21 elementary schools (45.1% boys; 40% white, 33% black, 9% Hispanic, and 18% other race/ethnicity) were assessed at least twice in ...

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), ...
