Volume, Patterns, and Types of Sedentary Behavior and Cardio-Metabolic Health in Children and Adolescents

  • Presented on 2011

Introduction Cardio-metabolic risk factors are becoming more prevalent in children and adolescents. A lack of moderate-to-vigorous intensity physical activity (MVPA) is an established determinant of cardio-metabolic risk factors in children and adolescents [1]. Less is known about the relationship between sedentary behavior and cardio-metabolic health. Therefore, the objective was to examine ...

Sedentary Time and Cardio-Metabolic Biomarkers in US Adults: NHANES 2003–06

  • Published on January 11, 2011

Aims Prolonged sedentary time is ubiquitous in developed economies and is associated with an adverse cardio-metabolic risk profile and premature mortality. This study examined the associations of objectively assessed sedentary time and breaks (interruptions) in sedentary time with continuous cardio-metabolic and inflammatory risk biomarkers, and whether these associations varied by ...

Seasonality in Physical Activity and Sedentary Behavior in Young Children

  • Published on 2005

This study examined whether there was a significant seasonal variation in objectively measured habitual physical activity and sedentary behavior in young children. Participants were 209 children who attend nursery in Glasgow, Scotland, and measurements were taken using uniaxial accelerometry over 3 to 6 days. There were small but significant seasonal associations with physical ...

Influence of Changes in Sedentary Behavior on Energy and Macronutrient Intake in Youth

  • Published on 02/2005

Background Changes in sedentary behavior may be related to changes in energy intake. Objective The purpose of this study was to investigate how experimental changes in the amount of sedentary behaviors influence energy intake. Design Sixteen non-overweight 12—16-yr-old youth were studied in a within-subject crossover design with three 3-wk phases: ...

Habitual Physical Activity and Sedentary Behaviour in a Clinical Sample of Obese Children

  • Published on 10/30/2006

Objective To objectively measure habitual physical activity and sedentary behaviour in a clinical sample of obese children and to compare with age- and sex-matched non-obese controls. DESIGN: Pairwise comparison of obese children matched for age and gender with non-obese controls. Subjects A total of 116 obese children (body mass index (BMI)> ...

Comparison of Pedometer and Accelerometer Accuracy Under Controlled Conditions

  • Published on May 2003

Purpose The purpose of this investigation was to compare the concurrent accuracy of the CSA accelerometer and the Yamax pedometer under two conditions: 1) on a treadmill at five different speeds and 2) riding in a motorized vehicle on paved roads. Methods In study 1, motion sensor performance was evaluated against actual steps ...
