Impact of a classroom standing desk intervention on daily objectively measured sedentary behavior and physical activity in youth

  • Published on Mar 2, 2018

Objectives: We investigated the impact of a standing desk intervention on daily objectively monitored sedentary behavior and physical activity in 6th grade school students. Design: Cluster non-randomised controlled trial. Method: Two classes (intervention students: n=22 [aged 11.8±0.4years]; control students: n=27 [11.6±0.5years]) from a public school in Lisbon were selected. The ...


Comparison of Two Generations of ActiGraph Accelerometers: The CARDIA Study

  • Published on Jun 2018

Purpose: This study aimed to examine the comparability of the ActiGraph 7164 and wGT3X-BT wear time, count-based estimates, and average time per day in physical activity of different intensities. Methods: We studied 87 Coronary Artery Risk Development in Young Adults (CARDIA) participants 48-60 yr of age who simultaneously wore the 7164 and ...


Objectively measured physical activity of hospital shift workers

  • Published on Jan 22, 2018

Objectives: Shift work may alter workers' leisure-time and occupational physical activity (PA) levels, which might be one of the potential underlying mechanisms of the negative health effects of shift work. Therefore, we compared objectively measured PA levels between hospital shift and non-shift workers. Methods: Data were used from Klokwerk+, a ...


Defining Accelerometer Nonwear Time to Maximize Detection of Sedentary Time in Youth

  • Published on Dec 23, 2017

Purpose: The present study examined various accelerometer nonwear definitions and their impact on detection of sedentary time using different ActiGraph models, filters, and axes. Methods: In total, 61 youth (34 children and 27 adolescents; aged 5-17 y) wore a 7164 and GT3X+ ActiGraph on a hip-worn belt during a 90-minute structured sedentary activity. ...


Are habitual runners physically inactive?

  • Published on Dec 25, 2017

Abstract: The World Health Organisation's (WHO) physical activity guidelines recommend 150min/week of moderate- to vigorous-intensity physical activity (MVPA) accumulated in 10 min bouts. To see whether people performing habitual exercise for recreation meet these guidelines, 25 long-distance runners [mean 67 km/wk], 25 joggers [mean 28 km/wk], and 20 sedentary adults wore an ActiGraph ...


Changes in Physical Activities and Body Composition after Roux-Y Gastric Bypass Surgery

  • Published on Jun 2018

Purpose: Given the importance of physical activities for health outcomes, it is still unclear whether bariatric surgery per se and the standard care after surgery would result in an increase of physical activity level. This study aimed to determine physical activities preoperatively and at 6 and 12 months postoperatively among female patients ...


Four years’ follow-up changes of physical activity and sedentary time in women undergoing roux-en-Y gastric bypass surgery and appurtenant children

  • Published on Dec 11, 2017

Background: Objectively measured levels of physical activity (PA) in patients undergoing Roux-en-Y Gastric Bypass (RYGB) surgery remain essentially unchanged from before to one year after surgery. Effects from RYGB on objectively measured levels of PA among women undergoing RYGB and appurtenant children beyond one year post-surgery are unknown. The aim ...


Demographic and clinical correlates of accelerometer assessed physical activity and sedentary time in lung cancer survivors

  • Published on Mar 2018

Objective: To determine demographic and clinical correlates of accelerometer assessed physical activity and sedentary time among a population-based sample of lung cancer survivors. Methods: Lung cancer survivors in Southern Alberta, Canada (N = 527) were invited to complete a mailed survey assessing socio-demographics and wear an Actigraph® GT3X+ accelerometer for 7 days. ...


Temporal and bi-directional associations between sleep duration and physical activity/sedentary time in children: An international comparison

  • Published on Jun 2018

Abstract: The purpose of this multinational and cross-sectional study was to investigate whether nighttime sleep duration was associated with physical activity (PA) and sedentary time (SED) the following day, whether daytime PA/SED were associated with sleep duration the subsequent night, and whether the associations were modified by sex and ...


Meeting new Canadian 24-Hour Movement Guidelines for the Early Years and associations with adiposity among toddlers living in Edmonton, Canada

  • Added on July 30, 2018

Background: Canada has recently released guidelines that include toddler-specific recommendations for physical activity, screen-based sedentary behaviour, and sleep. This study examined the proportions of toddlers meeting the new Canadian 24-Hour Movement Guidelines for the Early Years (0-4 years) and associations with body mass index (BMI) z-scores in a sample from ...
