Objectively measured physical activity and cardiac biomarkers: A cross sectional population based study in older men

  • Published on Jan 28, 2018

Background: N-terminal pro-brain natriuretic peptide (NT-proBNP) and high sensitivity Troponin T (hsTnT) are markers of cardiac injury used in diagnosis of heart failure and myocardial infarction respectively, and associated with increased risk of cardiovascular disease. Since physical activity is protective against cardiovascular disease and heart failure, we investigated whether higher ...


A Pilot Characterization of the Human Chronobiome

  • Published on Dec 07, 2017

Abstract Physiological function, disease expression and drug effects vary by time-of-day. Clock disruption in mice results in cardio-metabolic, immunological and neurological dysfunction; circadian misalignment using forced desynchrony increases cardiovascular risk factors in humans. Here we integrated data from remote sensors, physiological and multi-omics analyses to assess the feasibility of detecting ...


Objectively measured physical activity patterns, sedentary time and parent-reported screen-time across the day in four-year-old Swedish children

  • Published on Aug 1, 2017

Background: Physical activity (PA) improves health outcomes accumulating evidence suggests that sedentary time (ST), especially parent-reported screen-time, is associated with negative health outcomes in children. The aim of the present study is to describe levels and patterns of PA and ST across the day and week and activity pattern differences ...


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 ...


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 (...


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 ...


The moderating effect of psychosocial factors in the relation between neighborhood walkability and children’s physical activity

  • Published on Dec 9, 2016

Background: The study aimed to investigate if psychosocial factors moderate the association between objective walkability and different domains of children’s physical activity (PA). A second aim of the study was to investigate the direct associations between psychosocial factors and children’s PA. Based on previous literature, it was hypothesized ...


The Physical Activity and Redesigned Community Spaces (PARCS) Study: Protocol of a natural experiment to investigate the impact of citywide park redesign and renovation

  • Published on Nov 14, 2016

Background: The built environment plays a critical role in promoting physical activity and health. The association between parks, as a key attribute of the built environment, and physical activity, however, remains inconclusive. This project leverages a natural experiment opportunity to assess the impact of the Community Parks Initiative (CPI), a ...


Preschool and childcare center characteristics associated with children’s physical activity during care hours: an observational study

  • Published on Nov 11, 2016

Background: Preschools and childcare settings offer opportunities to promote adequate levels of physical activity. Research is needed to identify the key features of these settings to optimize young children’s activity. The aims of this study were to determine if differences existed in preschool children’s physical activity during care ...
