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 ...


Age- and sex-related differences in heart rate variability are present despite the suitable level of accelerometer-based physical activity

  • Published on May 2015

Background: Previous studies have described the age- and sex-related differences in heart rate variability (HRV) regardless of the level of physical activity in daily life (PADL). However, such studies were based in the assessment of PADL by means of questionnaires, which present important recall limitations. The influence of age and ...


Abstract MP026: Effects of Substituting Sedentary Behavior With Light and Moderate-to-vigorous Physical Activity on Obesity Indices in Adults

  • Published on Mar 7, 2017

Abstract: Sedentary behavior (SB) has emerged as an independent risk factor for the occurrence of cardiovascular problems and all-cause mortality. However, the deleterious effect of SB may be a consequence of replacing time spent in light and moderate-to-vigorous (MVPA) physical activities. Few studies have explored this topic, especially in prospective ...


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 (...


Dietary patterns in obese pregnant women; influence of a behavioral intervention of diet and physical activity in the UPBEAT randomized controlled trial

  • Published on Nov 29, 2016

Background: Understanding dietary patterns in obese pregnant women will inform future intervention strategies to improve pregnancy outcomes and the health of the child. The aim of this study was to investigate the effect of a behavioral intervention of diet and physical activity advice on dietary patterns in obese pregnant woman ...


Physical Activity and Pediatric Obesity: A Quantile Regression Analysis

  • Published on Mar 2017

Purpose: We aimed to determine whether moderate to vigorous physical activity (MVPA) and sedentary behavior (SB) were independently associated with body mass index (BMI) and waist circumference (WC) in children and adolescents. Methods: Data from the International Children's Accelerometry Database were used to address our objectives (N = 11,115; 6–18 yr; 51% female). We ...


Associations between self-reported and objectively measured physical activity, sedentary behavior and overweight/obesity in NHANES 2003–2006

  • Published on Oct 25, 2016

Objective: To investigate associations between self-reported and objectively measured physical activity, sedentary behavior and overweight/obesity based on percent body fat measured with Dual Energy X-Ray Absorptiometry (DXA), waist circumference (WC), waist-to-height ratio and body mass index, focusing on different intensities and domains of physical activity. Methods: Data from NHANES 2003–2006 ...


Association of the magnitude of weight loss and changes in physical fitness with long-term cardiovascular disease outcomes in overweight or obese people with type 2 diabetes: a post-hoc analysis of the Look AHEAD randomised clinical trial

  • Added on August 30, 2017

Background: Findings from the Look AHEAD trial showed no significant reductions in the primary outcome of cardiovascular disease incidence in adults with type 2 diabetes randomly assigned to an intensive lifestyle intervention for weight loss compared with those randomly assigned to diabetes support and education (control). We examined whether the incidence ...
