Childhood obesity has been attributed to a decline in total energy expenditure (TEE). We measured TEE, physical activity, and sedentary behaviour in a representative sample of young children from Glasgow, UK, at age 3 years (n=78), and we did a follow-up study at age 5 years (n=72). Mean physical activity level (TEE/...
The purpose of the present study was to systematically review published evidence on the reproducibility, validity, and feasibility of motion sensors used to assess physical activity in healthy children and adolescents (2-18 yr). Method A systematic literature search was performed in October 2004 in PubMed, Embase, and SpycINFO. The clinimetric quality ...
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 ...
A study in the Dec.1 issue of the journal Sleep suggests that changes in children’s sleep patterns that typically occur between the ages of 11 and 12 years are evident before the physical changes associated with the onset of puberty. Results show that over the two-year course of the study, sleep ...
Introduction Since low levels of PA may predispose children to obesity in later life, it is important to monitor and promote PA beginning as early as in preschool age. However, PA data in preschoolers are still limited. The present study aimed at investigating the effects of a structured PA session, ...
Objective To examine the cross-sectional relationships between physical activity and dietary behaviors among 8- to 10-year-old African-American girls. Research Methods and Procedures Two hundred ten 8- to 10-year-old African-American girls from four field centers participated. Computer Science and Applications (CSA) activity monitors were worn for 3 days. CSA data were expressed ...
Background/Objectives To test the association between physical activity measured using accelerometer counts (Actigraph) and energy expenditure (EE) measured using the doubly labelled water (DLW) method in free-living children in India. The aim of this study was to explore the usefulness of Actigraphs in estimating EE. Subjects/Methods Total EE (...
Background Strategies for the prevention and treatment of childhood obesity require a better understanding of the relation between the pattern of free-living physical activity and total energy expenditure (TEE). Objective We assessed the relations between TEE and physical activity level (PAL) during engagement in different intensities of physical activity. Design ...
Researchers support the relationship of task orientation with exerted effort persistence and self-reported physical activity but there is little evidence on the relation of goal perspectives with objective measures of physical activity The purpose of this study was to examine behavioral correlates of goal orientations using an objective measure of ...
Objectives Obesity rates are increasing among children of all ages, and reduced physical activity is a likely contributor to this trend. Little is known about the physical activity behavior of preschool-aged children or about the influence of preschool attendance on physical activity. The purpose of Ibis study was to describe ...
