Physical activity and risk of breast cancer, colon cancer, diabetes, ischemic heart disease, and ischemic stroke events: systematic review and dose-response meta-analysis for the Global Burden of Disease Study 2013

  • Published on Aug 9, 2016

Objective: To quantify the dose-response associations between total physical activity and risk of breast cancer, colon cancer, diabetes, ischemic heart disease, and ischemic stroke events. Design: Systematic review and Bayesian dose-response meta-analysis. Data Sources: PubMed and Embase from 1980 to 27 February 2016, and references from relevant systematic reviews. Data from the Study ...


A non-equivalent group pilot trial of a school-based physical activity and fitness intervention for 10–11 year old english children: born to move

  • Published on Aug 24, 2016

Background: PE lessons are the formal opportunity in schools for promotion of physical activity and fitness. This study aimed to evaluate the effectiveness of a pilot PE intervention on physical activity, fitness, and psychosocial outcomes. Methods: Participants were 139 children aged 10–11 years from four schools. For six weeks children in ...


Comparison of wrist-worn Fitbit Flex and waist-worn ActiGraph for measuring steps in free-living adults

  • Published on Feb 24, 2017

Introduction: Accelerometers are commonly used to assess physical activity. Consumer activity trackers have become increasingly popular today, such as the Fitbit. This study aimed to compare the average number of steps per day using the wrist-worn Fitbit Flex and waist-worn ActiGraph (wGT3X-BT) in free-living conditions. Methods: 104 adult participants (n = 35 ...


Reliability and validity of the French version of the global physical activity questionnaire

  • Published on Aug 15, 2016

Background: The Global Physical Activity Questionnaire (GPAQ) has been used to measure physical activity (PA) and sedentary time in France, but no study has assessed its psychometric properties. This study aimed to compare the reliability as well as criterion and concurrent validity of the French version of the GPAQ with ...


Does home equipment contribute to socioeconomic gradients in Australian children’s physical activity, sedentary time and screen time?

  • Published on Aug 5, 2016

Background: Activity behaviours (physical activity, sedentary time and screen time) have been linked to health outcomes in childhood. Furthermore, socioeconomic disparities have been observed in both children’s activity behaviours and health outcomes. Children’s physical home environments may play a role in these relationships. This study aimed to examine ...


Permanent play facility provision is associated with children’s time spent sedentary and in light physical activity during school hours: A cross-sectional study

  • Published on Dec 2016

Objective: To study the associations between: 1) number of permanent outdoor play facilities per pupil and 2) the size of the outdoor play area per pupil with sedentary time and physical activity (PA) during school hours in six-, nine-, and 15-year olds. We conducted a cross-sectional study of nationally representative samples of ...


Measuring moderate-intensity walkingin older adults using the ActiGraph accelerometer

  • Published on 2016

Background: Accelerometry is the method of choice for objectively assessing physical activity in older adults. Many studies have used an accelerometer count cut point corresponding to 3 metabolic equivalents (METs ) derived in young adults during treadmill walking and running with a resting metabolic rate (RMR) assumed at 3.5 mL · kg−1·...


Methodology to Promote Physical Activity Monitoring Adherence in Youth with Autism Spectrum Disorder

  • Published on Sep 27, 2016

Background: Objective physical activity (PA) monitoring via accelerometry is both costly and time consuming. Furthermore, overall adherence to a monitoring protocol is often complicated by disability. Therefore, it is essential that strategies for supporting accelerometer wear for youth with disabilities are maximized. The purpose of this perspective was to provide ...


Calibrating physical activity intensity for hip-worn accelerometry in women age 60 to 91 years: The Women’s Health Initiative OPACH Calibration Study

  • Published on 2015

Objective: We conducted a laboratory-based calibration study to determine relevant cutpoints for a hip-worn accelerometer among women ≥60 years, considering both type and filtering of counts. Methods: Two hundred women wore an ActiGraph GT3X+ accelerometer on their hip while performing eight laboratory-based activities. Oxygen uptake was measured using an ...


Comparison of physical activity assessed using hip- and wrist-worn accelerometers

  • Published on Feb 2016

Objectives: It is unclear how physical activity estimates differ when assessed using hip- vs wrist-worn accelerometers. The objective of this study was to compare physical activity assessed by hip- and wrist-worn accelerometers in free-living older women. Design: A cross-sectional study collecting data in free-living environment. Methods: Participants were from the ...
