How Are Physical Activity, Fitness, and Sedentary Behavior Associated With Insulin Sensitivity in Children?

  • Published on May 11, 2012

Objective To describe the associations among moderate-to-vigorous physical activity (MVPA), fitness, sedentary behavior (SB), and insulin sensitivity (IS). Research Designs & Methods Data were drawn from the baseline assessment of the QUALITY cohort, which included 630 white youth (aged 8–10 years at recruitment), with at least one obese biological parent. IS was ...


Factors Associated with Sedentary Lifestyle of Hospitalized Patients Not Restricted to Bed

  • Added on October 30, 2013

Introduction The prolonged length of stay on the bed is related to the development of musculoskeletal and respiratory disorders. Therefore, the investigation of the level of physical activity and to verifying which factors are associated with the physical activity level in hospitalized patients might be important for future strategies to ...


Actigraph Accelerometer-Defined Boundaries for Sedentary Behaviour and Physical Activity Intensities in 7 Year Old Children

  • Published on Aug. 11, 2011

Background Accurate objective assessment of sedentary and physical activity behaviours during childhood is integral to the understanding of their relation to later health outcomes, as well as to documenting the frequency and distribution of physical activity within a population. Purpose To calibrate the ActiGraph GT1M accelerometer, using energy expenditure (...



Validation of the use of Actigraph GT3X accelerometers to estimate energy expenditure in full time manual wheelchair users with spinal cord injury

  • Added on September 16, 2013

Objectives: The goals of this study were to validate the use of accelerometers by means of multiple linear models (MLMs) to estimate the O2 consumption (VO2) in paraplegic persons and to determine the best placement for accelerometers on the human body. Methods: Twenty participants (age=40.03 years, weight=75.8 kg and height=1.76 ...


Sedentary behavior and psychiatric symptoms in overweight and obese adults with schizophrenia and schizoaffective disorders (WAIST Study)

Physical Activity, Sedentary Behavior and C-Reactive Protein in Pregnancy

  • Published on July 15, 2013

Introduction: Elevated C-reactive protein (CRP) is associated with adverse pregnancy outcomes. In non-pregnant populations, physical activity has been inversely associated with CRP, but this association has not been evaluated during pregnancy. The purpose of this study was to evaluate the association between objectively measured physical activity, sedentary behavior, and CRP ...



Seasonal Variation In Objectively Measured Physical Activity, Sedentary Time, And Sleep Duration Among Children

  • Presented on June 17, 2013

Purpose Understanding fluctuations in lifestyle indicators is important to identify relevant time periods to intervene in order to promote a healthy lifestyle; however, objective assessment of multiple lifestyle indicators has never been done using a repeated-measures design. The primary aim was, therefore, to examine between-season and within-week variation in physical ...


Accounting For Physical Activity In Sedentary Behaviour Research: A Theoretical Framework

  • Presented on June 17, 2013

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 ...
