Background: Use of mass transit has been proposed as a way to incorporate regular physical activity into daily life because transit use typically requires additional travel to access and depart the stop or station. If this additional travel is active, a small but potentially important amount of physical activity can ...
INTRODUCTION: Wearable accelerometers have become ubiquitous in the fields of exercise physiology and ambulatory hospital settings. However, these devices have yet to be validated in extreme operational environments. The objective of this study was to correlate the gravitational forces (G forces) detected by wearable accelerometers with the G forces detected ...
Purpose: Previously, studies examining correlates of sedentary behavior have been limited by small sample size, restricted geographic area, and little socio-cultural variability. Further, few studies have examined correlates of total sedentary time (SED) and screen time (ST) in the same population. This study aimed to investigate correlates of SED and ...
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 ...
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 ...
Background: Studies have found an association between television (TV) viewing and physical activity levels. The purpose of this study was to examine the association between TV viewing and physical activity in 10-year old Brazilian children. Methods: The sample consisted of 485 children. Self-reported TV viewing on weekdays and weekends was assessed ...
Background: Childhood obesity is an increasing health problem globally. Overweight and obesity may be established as early as 2–5 years of age, highlighting the need for evidence-based effective prevention and treatment programs early in life. In adults, mobile phone based interventions for weight management (mHealth) have demonstrated positive effects on body ...
Abstract: This article describes the multi-method cross-sectional design used to evaluate New York City Department of Health and Mental Hygiene’s regulations of nutrition, physical activity, and screen time for children aged 3 years or older in licensed group child care centers. The Center Evaluation Component collected data from a stratified ...
Background: Screen time (including TV viewing/computer use) may be adversely associated with metabolic and mental health in children. Purpose: To describe the prevalence and sociodemographic correlates of screen time in an international sample of children aged 4–17 years. Methods: Data from the International Children’s Accelerometry Database were collected between 1997–2009 ...
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 ...
