A randomised controlled trial of a physical activity and nutrition program targeting middle-aged adults at risk of metabolic syndrome in a disadvantaged rural community

  • Published on 2015

Background: Approximately 70% of Australian adults aged over 50 are overweight or obese, with the prevalence significantly higher in regional/remote areas compared to cities. This study aims to determine if a low-cost, accessible lifestyle program targeting insufficiently active adults aged 50-69 y can be successfully implemented in a rural location, and ...


Classification of physical activity intensities using a wrist-worn accelerometer in 8–12-year-old children

  • Published on April 20, 2015

Background: Population-specific accelerometer cut-points are required to accurately determine the accumulation of physical activity of various intensities. Objectives: A calibration study was conducted (i) to determine the cut-points for the ActiGraph GT3X+, non-dominant, wrist-mounted accelerometer in children aged 8–12 years and (ii) to compare classification accuracies among the accelerometer's three ...


Regional differences of physical activity and sedentary behaviour in Swiss children are not explained by socio-demographics or the built environment

  • Published on Jan. 8, 2015

Objective: We evaluated whether regional differences in physical activity (PA) and sedentary behaviour (SB) exis- ted along language boundaries within Switzerland and whether potential differences would be explained by socio- demographics or environmental characteristics. Methods: We combined data of 611 children aged 4 to 7 years from four regional studies. PA and SB ...


Light Intensity Physical Activity and Sedentary Behavior in Relation to Body Mass Index and Grip Strength in Older Adults: Cross-Sectional Findings from the Lifestyle Interventions and Independence for Elders (LIFE) Study

  • Published on Feb. 3, 2015

Background: Identifying modifiable determinants of fat mass and muscle strength in older adults is important given their impact on physical functioning and health. Light intensity physical activity and sedentary behavior are potential determinants, but their relations to these outcomes are poorly understood. We evaluated associations of light intensity physical activity ...


Interventions for physical activity promotion applied to the primary healthcare settings for people living in regions of low socioeconomic level: study protocol for a non-randomized controlled trial

  • Published on March 13, 2014

Background: Regular physical activity practice has been widely recommended for promoting health, but the physical activity levels remain low in the population. Therefore, the study of interventions to promote physical activity is essential. Objective: To present the methodology of two physical activity interventions from the “Ambiente Ativo” (“Active Environment”) project. ...


Does participation in a physical activity program impact upon the feet of overweight and obese children?

  • Published on Nov. 13, 2014

Objectives: To investigate the effect of a weight-bearing physical activity program on foot structure and plantar pressures generated by overweight/obese children. Design: Descriptive study. Methods: Measurements were collected for a sample of children participating in an obesity treatment trial (mean ± SD 8.5 ± 1.1 y, 29.4% boys, 2.63 ± 0.61 body mass index z-score). Children were ...


Workplace Sitting Breaks Questionnaire (SITBRQ): an assessment of concurrent validity and test-retest reliability

  • Published on Dec. 5, 2014

Background: Breaks in prolonged sitting may have beneficial cardiometabolic and musculoskeletal health outcomes. Desk-based work settings are an important environment to promote and support breaks in sitting time. However, few studies have reported the psychometric properties of self-report measures to assess the frequency and duration of breaks from sitting. This ...


Different conceptual constructs for modelling sedentary behaviour and physical activity: the impact on the correlates of behaviour

  • Published on Dec. 16, 2014

Background: Research on the correlates of physical activity (PA) and sedentary behaviour (SB) to date has used independent prediction equations for each behaviour, without considering that they are both part of the same continuum of movement. This assumption of independence might lead to inaccurate estimates because common underlying latent variables ...


Association Between Television Viewing and Physical Activity in 10-year Old Brazilian Children

  • Published on March 31, 2015

Background: Studies have found an association between television (TV) viewing and physical activity levels. The purpose of this study was to examine the association between TV viewing and physical activity in 10-year old Brazilian children. Methods: The sample consisted of 485 children. Self-reported TV viewing on weekdays and weekends was assessed ...


Moderate-to-Vigorous Physical Activity and Sedentary Behavior: Independent Associations With Body Composition Variables in Brazilian Children

  • Published on April 22, 2015

Abstract: This study aimed to analyze the independent associations of accelerometer-determined sedentary behavior (SB), physical activity, and steps/day with body composition variables in Brazilian children. 485 children wore accelerometers for 7 days. Variables included time in SB and different physical activity intensities (light or LPA, moderate or MPA, vigorous or VPA, ...
