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 The aim of this study was to develop objective measures of park use and to describe patterns of park use and its association with moderate-to-vigorous physical activity (MVPA) among adults. Methods From five US states, 238 adults were enrolled in or near 31 study parks. Participants wore a global positioning system (...
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 Evaluate the reliability and validity of a self-reported moderate-to-vigorous physical activity (MVPA) instrument administered by telephone and Internet. Methods The Active Australia Survey (AAS), administered nationally in Australia by telephone (T), was adapted into two forms for Internet self-administration: survey questions only (I-Text) and with videos demonstrating intensity (I-Video). ...
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 ...
Purpose This study aimed to test the validity of the Global Physical Activity Questionnaire (GPAQ) against accelerometer data, as feasible, cost-effective instruments are required for the surveillance of physical activity (PA). The questionnaire has been previously assessed in terms of reproducibility and validity however, validation produced poor results and further ...
Purpose To compare associations between objective and subjective measures of moderate to vigorous physical activity (MVPA) & cardiometabolic biomarkers. Methods 2174 (1110 boys) youth (12-19 years) from the 2003-6 NHANES combined surveys with self-reported MVPA (SRMVPA) in the previous 30 days & four 10-hour days of accelerometry MVPA (AMVPA) (Actigraph 7164) were included. The ...
