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 ...
Purpose Children’s independent mobility may correlate with physical activity; however it may also expose them to more sweet and fast food shops, potentially explaining the caloric intake in young people. This cross-sectional study investigated whether independent mobility is preadolescents was related to caloric intake. Methods Six hundred and thirty ...
Purpose Low levels of physical activity (PA) have been associated with increased risk of child overweight. Multiple studies show that young children are not getting the recommended 60 minutes of PA during their 8-hour day in childcare. (Reilly, 2010) This study will explored whether time spent in childcare is related to children’...
Purpose To evaluate the multi-group and longitudinal invariance of ANNs to predict physical activity (PA) type and PA energy expenditure (METs) in youth. Methods The study was conducted at two sites. Site 1 (S1) served as the training and testing sample and comprised 100 youth mean age 11.0 ± 2.7 y. Site 2 (S2) served as ...
Purpose A number of recent studies have found associations between the characteristics of schoolyards and the level of PA of schoolchildren using the schoolyards. Based on these findings, it seems likely that making schoolyards more attractive will help to increase the total amount of PA among schoolchildren. Before starting our ...
Purpose Published experiences of using accelerometers in very young children are scarce. This study tested the usability of one accelerometer type, ActiGraph GT3X, in assessing free-living physical activity of 1.5 year-old Malawian children. Methods Fifty-two Malawian children [23 boys, mean age 17.0 months (range 16.0 – 18.5), mean HAZ -0.83, mean WHZ 0.08] from rural Lungwena ...
Purpose To inform intervention development by investigating predictors of one-year change in objectively-measured intensity of physical activity (PA) in a cohort of 9-10 year old British school children. Methods In a cohort of 753 children in Norfolk (UK) (41.7% male, baseline age (mean±SD): 9.7±0.4 years) PA was measured over 3 or more days ...
Background Hispanic-American preschool children have higher rates of obesity and Hispanic-American youth may be at higher risk for sedentary lifestyles and metabolic syndrome. Both physical and social environmental factors influence young children’s physical activity. The ability to simultaneously capture objective measurement of physical activity and location of young Hispanic-American ...
Background Evidence suggests that parents play an important role in shaping children’s physical activity levels through behavioral modeling and support. Physically active parents are more likely to have physically active children. However, research indicates that on average, parents and children spend less than 5 minutes per day engaging in physical ...
A calibration study was conducted to determine the threshold counts for two commonly used accelerometers, the ActiGraph and the Actical, to classify activities by intensity in children 5 to 8 years of age. Thirty-three children wore both accelerometers and a COSMED portable metabolic system during 15 min of rest and then performed up ...
