Effects of a peer-led Walking In ScHools intervention (the WISH study) on physical activity levels of adolescent girls: a cluster randomised pilot study

  • Published on Jan 11, 2018

Background: School-based interventions may be effective at increasing levels of physical activity (PA) among adolescents; however, there is a paucity of evidence on whether walking can be successfully promoted to increase PA in this age group. This pilot study aimed to assess the effects of a 12-week school-based peer-led brisk ...


Association between Physical Activity and Adiposity in Adolescents with Down Syndrome

  • Published on Apr 2018

Purpose: Obesity is highly prevalent among adolescents with Down syndrome (DS); however, reported associations between body composition and moderate-to-vigorous physical activity (MVPA) have been small and nonsignificant. The purpose of this study was to compare group differences between adolescents with and without DS, including dual-energy x-ray absorptiometry (DXA) measured body ...


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 ...


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 ...
