Accelerometers could potentially be used to assess physical activity and sleep using the same monitor; however, two different positions are typically used for the assessment of physical activity and sleep (waist and wrist, respectively). The aim of this study is to evaluate the concordance between wrist- and waist-worn Actigraphs for ...
Objectives: To measure sleep duration in 7-year-old children; identify the determinants of sleep duration; and assess the association between short sleep duration and obesity, cognitive functioning, and behaviour. Design: Longitudinal study with disproportionate sampling of the participants. Setting: Community. Participants: 591 seven-year-old children, of whom 519 had complete sleep data. Interventions: Not ...
Background: To provide more accurate assessment of commuting behavior and potential health effect, it is important to have accurate methods. Therefore, the current study aimed to a) compare questionnaire reported mode of commuting with objectively measured data from accelerometer and cycle computer, b) compare moderate vigorous physical activity (MVPA) among ...
Understanding the determinants of physical activity behavior in children and youths is essential to the design and implementation of intervention studies to increase physical activity. Objective methods to assess physical activity behavior using various types of motion detectors have been recommended as an alternative to self-report for this population because ...
Background: This pragmatic evaluation investigated the effectiveness of the Children’s Health, Activity and Nutrition: Get Educated! (CHANGE!) Project, a cluster randomised intervention to promote healthy weight using an educational focus on physical activity and healthy eating. Methods: Participants (n = 318, aged 10–11 years) from 6 Intervention and 6 Comparison schools took part in ...
Background: We conducted a comparative effectiveness analysis to evaluate the difference in the amount of physical activity children engaged in when enrolled in a physical activity-enhanced after-school program (ASP) based in a community recreation center versus a standard school-based ASP. Methods: The study was a natural experiment with 54 elementary school ...
Background: Eating breakfast is believed to promote a healthy body weight. Yet, few studies have examined the contribution of energy balance–related behavioral factors to this relation in minority youth. Objective: We assessed the associations between breakfast consumption and dietary intake, physical activity (PA), and adiposity before and after accounting ...
Commentary: Britt Johnson, National Heart Foundation Encouraging children to actively commute to school is a public health strategy that helps to incorporate physical activity into daily life. This paper presents the results of a longitudinal investigation into the individual, socio-cultural and environmental predictors of active commuting to school amongst 9-10 ...
Aim: The benefits of promoting physical activity (PA) in counteracting the high prevalence of childhood obesity have become increasingly important in the past decade. The aim of this study was to examine the association between compliance of daily PA recommendations and the risk of being overweight or obese in preschool-aged ...
Background: Increasing school-day physical activity through policy and programs is commonly suggested to prevent obesity and improve overall child health. However, strategies that focus on school-day physical activity may not increase total physical activity if youth compensate by reducing physical activity outside of school. Purpose: Objectively measured, nationally representative physical ...
