Background The aim of this study was to examine the differences in diet, physical activity, and weight status among children living in rural and urban America and to study the roles of obesity-related behaviors in residence-based differences in childhood obesity. Methods We performed cross-sectional analysis of the 1999-2006 National Health ...
Background Leptin may influence moderate to vigorous physical activity (MVPA) at the start of puberty. The direction and magnitude of this association are unclear. Objectives To determine the effect of baseline leptin on MVPA over 1 year in minority girls at high risk for obesity. Methods Data came from TRANSITIONS, a ...
Summary Physical activity declines as children enter puberty. Leptin is cross-sectionally associated with physical activity, but there are conflicting findings on the magnitude and direction of this association. Leptin concentrations fluctuate during puberty, and may impact energy balance. Leptin predicts the decline in physical activity during the start of puberty ...
Summary There is an association between adiposity levels and physical activity guidelines for adolescents. Achieving physical activity recommendations helps adolescents to prevent obesity status. This paper presents an association between physical activity levels and obesity status. This paper supports physical activity recommendations to avoid children's obesity levels. This paper emphasizes ...
My coeditors and I are delighted to share this special issue of the Journal of Obesity focused on understanding the comorbidity between obesity and depression. Depression is highly comorbid with obesity [1–3] and may impede weight loss treatment [4–9]. Just as a successful reduction in the obesity epidemic must entail a multilevel ...
Introduction Relapse in the first 3-5 years following weight loss is a common problem in obesity management (Ross, 2009). The extent to which physiological (Jackman et al., 2008) vs behavioural adaptations contribute to weight loss relapse is not clearly understood. Moreover, there is some indication that an ‘energy gap’ or leading to ...
Introduction physical activity (PA) is perceived to be a key determinant of childhood adiposity. This study objectively characterizes the daily PA of 7-year-olds and relates it to waking time, intensity, UK recommendations and body fat. Methods and Participants MTI-Actigraph accelerometers were worn by 129 (88) healthy boys (girls) for seven days. Calibration ...
Introduction There is much interest in children’s physical activity (PA), but little understanding of its control. The evidence that total activity levels could be increased by the provision of greater opportunity for physical activity is lacking. Methods and Participants MTI-Actigraph accelerometers recorded weekly PA in two groups of healthy ...
Purpose To examine the effects of short bouts of structured physical activity (PA) on during-school total PA in lower socioeconomic status preschoolers. Methods Ten preschool centers serving low-income families will be recruited and randomly assigned to one of two groups. Treatment preschools will implement the Tutti Fruitti Instant Recess intervention ...
Background Determining the relation of built environment characteristics to physical activity and obesity remains an ongoing public health concern. Recent literature suggests that environment characteristics of smart growth planning (e.g., walkability, preservation of open space) may promote physical activity. However, the majority of studies examining associations between these environmental ...
