Calibration of the global physical activity questionnaire to Accelerometry measured physical activity and sedentary behavior

  • Published on March 27, 2018

Background Self-report questionnaires are a valuable method of physical activity measurement in public health research; however, accuracy is often lacking. The purpose of this study is to improve the validity of the Global Physical Activity Questionnaire by calibrating it to 7 days of accelerometer measured physical activity and sedentary behavior. Methods ...


Change in Physical Activity During Active Treatment of Cardiac Patients

  • Published on April 2017

Abstract: Sedentary secular, domestic, and recreational behaviour is a major risk factor (RF) for cardiovascular disease (CVD). This study examines the quality of at-home physical activity (PA) and how it relates to physical fitness (PF) before and during 12 weeks of supervised cardiac rehabilitation (CR) in a group of medically referred ...




Using open source accelerometer analysis to assess physical activity and sedentary behaviour in overweight and obese adults

  • Published on Apr 2018

Background: Physical activity and sedentary behaviour are difficult to assess in overweight and obese adults. However, the use of open-source, raw accelerometer data analysis could overcome this. This study compared raw accelerometer and questionnaire-assessed moderate-to-vigorous physical activity (MVPA), walking and sedentary behaviour in normal, overweight and obese adults, and determined ...


Associations of objectively assessed physical activity and sedentary time with health-related quality of life among lung cancer survivors: A quantile regression approach

  • Published on Apr 2018

Objectives: No studies have examined objectively assessed physical activity, sedentary time, and patient-reported outcomes among lung cancer survivors. The objective of this study was to determine associations of objectively assessed moderate-to-vigorous intensity physical activity (MVPA) and sedentary time with health-related quality of life (HRQoL) and fatigue among lung cancer survivors. ...


Measurement of Active and Sedentary Behavior in Context of Large Epidemiologic Studies

  • Published on Feb 2018

Introduction/Purpose: To assess the utility of measurement methods that may be more accurate and precise than traditional questionnaire-based estimates of habitual physical activity and sedentary behavior we compared the measurement properties of a past year questionnaire (AARP) and more comprehensive measures: an internet-based 24-h recall (ACT24), and a variety ...


Comparability of children’s sedentary time estimates derived from wrist worn GENEActiv and hip worn ActiGraph accelerometer thresholds

  • Published on Apr 2018

Objectives: To examine the comparability of children’s free-living sedentary time (ST) derived from raw acceleration thresholds for wrist mounted GENEActiv accelerometer data, with ST estimated using the waist mounted ActiGraph 100 count · min−1 threshold. Design: Secondary data analysis. Methods: 108 10–11-year-old children (n = 43 boys) from Liverpool, UK wore one ActiGraph GT3...


Domain-Specific Adult Sedentary Behaviour Questionnaire (ASBQ) and the GPAQ Single-Item Question: A Reliability and Validity Study in an Asian Population

  • Published on Apr 2018

Abstract: This study examined the validity and reliability of a domain-specific Adult Sedentary Behaviour Questionnaire (ASBQ) and the Global Physical Activity Questionnaire (GPAQ) single-item sitting question using self- and interviewer-administered modes of administration against the triaxial ActiGraph wGT3X-BT accelerometer. The ASBQ and the GPAQ were administered twice, seven days ...


Association between physical activity in daily life and pulmonary function in adult smokers

  • Published on Apr 2016

Objective: To determine whether the level of physical activity in daily life (PADL) is associated with pulmonary function in adult smokers. Methods: We selected 62 adult smokers from among the participants of an epidemiological study conducted in the city of Santos, Brazil. The subjects underwent forced spirometry for pulmonary function assessment. ...
