Background: The study objectives were to examine whether: 1) sedentary time is associated with sleep duration, 2) sedentary time predicts the metabolic syndrome (MetS) independent of sleep duration and vice versa, and 3) sedentary time and sleep duration have an interactive effect on the MetS. Methods: This cross-sectional study is based on the 2003–2006 ...
Purpose: To examine the associations between objectively measured physical activity (PA), sedentary time, and health-related fitness; and to investigate the combined association of PA and sedentary time on health-related fitness in youth. Methods: PA and sedentary time were assessed with accelerometers in 2506 youth aged 10-18 years (M age=13.2+/-2.3). Participants ...
Introduction: Mindfulness skills, psychological flexibility and psychological symptoms were compared among 58 physically less active and 50 physically active adults who were recruited and classified based on their self-reported physical activity. Additionally, this study evaluated the association of objectively measured physical activity with psychological variables. Methods: Participants completed questionnaires evaluating their mindfulness ...
Background: A number of studies have suggested that there is a need to increase the physical activity levels of children. Parents are important influences on children’s behaviour. There is a lack of information about whether there are associations between the physical activity levels of young children and their parents. ...
Introduction: Very little is known about physical activity (PA) and PA patterns measured with objective methods among children with intellectual disability (ID). Purpose: To investigate PA and PA patterns among Icelandic school children with mild-to-severe ID. Methods: A sample of 91 children with ID and a randomly selected age- and sex-matched ...
Objectives: To validate the GT1M actigraph accelerometer step count function, and the Omron Walking Style Pro pedometer against accelerometer-based activity counts, and to compare pedometer-based and accelerometer-based steps in preschoolers. Design: A sample of 41 preschoolers (21 boys, mean age 5.43 ± 0.63 years) from one preschool in Flanders, Belgium, was included in data ...
Background: There is some evidence that physical activity (PA), sedentary time and screen time (ST) are associated with childhood obesity, but research is inconclusive and studies are mainly based on self-reported data. The literature is dominated by data from North American countries and there is a shortage of objective data ...
Purpose: Environmental changes are potentially effective population-level physical activity (PA) promotion strategies. However, robust multi-site evidence to guide international action for developing activity-supportive environments is lacking. We estimated pooled associations of perceived environmental attributes with objectively-measured PA outcomes; between-site differences in such associations; and, the extent to which perceived environmental ...
Aims: Recent literature has posed sedentary behaviour as an independent entity to physical inactivity. This study investigated whether associations between sedentary behaviour and cardio-metabolic biomarkers remain when analyses are adjusted for total physical activity. Methods: Cross-sectional analyses were undertaken on 4,618 adults from the 2003/04 and 2005/06 U.S. National Health and Nutrition ...
Introduction: The association between habitual sleep patterns and cardiac autonomic modulation (CAM) in adolescents is not fully understood. We investigated such association in the population-based Penn State Child Cohort (PSCC) follow-up examination. Methods: An actigraph (GT3X) and a sleep diary were used in 421 adolescents for 7 consecutive nights to calculate ...
