Background: The need to understand where and how much physical activity (PA) children accumulate has become important in assisting the development, implementation, and evaluation of PA interventions. The purpose of this study was to describe the daily PA patterns of children during the segmented school-week.
Methods: 829 children participated by wearing pedometers (Yamax-Digiwalker SW-200) for 5 consecutive days.
Background: The purposes of this study were to describe and analyze the steps/d of nonwhite minority children and youth by gender, grade level, race/ethnicity, and mode of school transportation. A secondary purpose was to compare the steps/d of minority children and youth to their Caucasian grade-level counterparts.
Methods: Participants were 547 minority youth grades 5 to 8 from 4 urban schools.
Background: The purpose of this study was to conduct a secondary analysis by combining 2 pedometer data sets to describe and analyze pedometer-determined steps/day of children by ethnicity and metropolitan status.
Methods: Participants were 582 children (309 girls, 273 boys; 53% Hispanic, 26% Caucasian, 21% African American) age 10 to 11 years (M = 10.37 +/- 0.
Background: The purpose of this study was to cross-validate international BMI-referenced steps/d cut points for US girls (12,000 steps/d) and boys (15,000 steps/d) 6 to 12 years of age.
Methods: Secondary pedometer-determined physical activity data from US children (N=1067; 633 girls and 434 boys, 6 to 12 years) were analyzed. Using international BMI classifications, cross-validation of the 12,000 and 15,000 steps/d cut points was examined by the classification precision, sensitivity, and specificity for each age-sex stratum.
