Objective Little research has investigated children’s physical activity levels during school recess and the contribution of recess to school day physical activity levels by weight status. The aims of this study were to examine non-overweight and overweight children’s physical activity levels during school recess, and examine the contribution ...
Background The magnitude of the association between physical activity (PA) and obesity has been difficult to establish using questionnaires. The aim of the study was to evaluate patterns of PA across BMI-defined weight categories and to examine the independent contribution of PA on weight status, using accelerometers. Methods The study ...
Background Ineffective family interventions for the prevention of childhood obesity have, in part, been attributed to the challenges of reaching and engaging parents. With a particular focus on parent engagement, this study utilized community-based participatory research to develop and pilot test a family-centered intervention for low-income families with preschool-aged children ...
Aim We aimed to study the sedentary behaviour and obesity levels in 123 students of the 7th grade and their implications in blood pressure levels. Methods Sedentary behavior and physical activity were assessed with accelerometry. Blood pressure was measured and for both systolic blood pressure and diastolic blood pressures Z-scores adjusted ...
Aim The purpose of the present study was to analyse differences in blood pressure between different levels of cardiorespiratory fitness (CRF) controlling for the influences of age, sex, waist circumference (WC) and objectively measured physical activity levels (PA). Methods Participants were 405 students aged 10-19 years (239 girls and 166 boys) from North ...
Aim The aim of this cross-sectional study was to explore relationships between motor coordination coefficient (MC), cardiorespiratory fitness (VO2max) moderate to vigorous physical activity (MVPA) and percentage of body fat (%BF) in children and adolescents from 6 to 19 years. Methods 108 children and adolescents (65 girls, 60.2%) from 6 schools in Porto district took ...
Aim To investigate eight-year changes in fatness, fitness and physical activity in a cohort of Icelandic children by comparing measurements conducted at two different time points. Methods In 2003 a total of 489, 9-year-olds participated in a study called Lifestyle of 9 and 15 year-old Icelanders. A total of 258 from this cohort were recruited ...
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 ...
