Background: Physical activity and sedentary behaviour in youth have been reported to vary by sex, age, weight status and country. However, supporting data are often self-reported and/or do not encompass a wide range of ages or geographical locations. This study aimed to describe objectively-measured physical activity and sedentary time ...
Background: Misreporting of energy intake is well known from traditional dietary assessment methods, and assessment among the youngest is especially challenging. Web-based tools are increasingly popular. However, little is known whether these web-tools improve the recording accuracy. Objective: To assess the accuracy of children and adolescent's energy intake estimated from ...
Introduction: This study examined agreement between activPAL3 (AP) and ActiGraph (AG) wrist and hip cut-points for assessing sedentary behaviour (SB) among 5-12 year-old children using direct observation (DO) as the criterion. Methods: 30 children (9.2±2.1y, 53.3% boys) wore AG on both wrists and the right hip and a thigh-mounted AP while completing 15 5...
Background: Research into participants' perceptions of the physical activity measurement process is sparse. The primary aim was to explore adolescents' perceptions of pedometers and investigate their physical activity behaviours. Methods: The sample included 123 adolescents (14.7 ± 0.5 years) from three secondary schools in NSW, Australia. Schools were randomized to one of three pedometer ...
Abstract: The movement of preschool children happens on several planes more often compared school-aged children or adults. The accelerometers, such as Actigraphs, are used for measuring children's moderate-to-vigorous activity (MVPA), and the current models of accelerometers allow measuring movement on three different axis. To our knowledge, there is currently only ...
Abstract: The accelerometers, such as the Actigraphs, are used in measuring preschool children's sedentary time. There are several cut-points age-specifically designed for preschool children, and most of these cut-points have different count per minute (cpm) estimate for sedentariness. The aim of this study was to assess preschool children's sedentary minutes ...
Background: Measuring physical activity and sedentary time in the early years (0-4 years) with accelerometers presents unique challenges due to daytime naps. Currently, an established procedure to determine daytime naps from accelerometer data in this age group does not exist. The purpose of this study was to examine differences in ...
Objective: Healthy lifestyles such as being physically active and eating a healthy diet help reduce the childhood obesity risk. However, population-level studies on the relationship between lifestyles and childhood obesity typically focus on either physical activity or diet but seldom both. This study examined physical activity and diet quality in ...
Background: Gardens are a promising intervention to promote physical activity (PA) and foster health. However, because of the unique characteristics of gardening, no extant tool can capture PA, postures, and motions that take place in a garden. Methods: The Physical Activity Research and Assessment tool for Garden Observation (PARAGON) was ...
Background: There is little current understanding of the influences on sedentary behavior and screen time in preschool children. This study investigated socioeconomic position (SEP) and parental rules as potential correlates of preschool children’s sedentary behavior and screen time. Methods: Data from the Healthy Active Preschool Years (HAPPY) Study were ...
