Pedometer-determined physical activity levels of adolescents: differences by age, sex, time of week, and transportation mode to school.

چکیده
BACKGROUND Few studies have examined high school students' physical activity habits using objective measures. The purpose of this study was to describe pedometer-determined habitual physical activity levels of youth. METHODS 236 high school students (age 12-18 years) wore sealed pedometers for 5 consecutive days. Data were analyzed using generalizing estimating equations. RESULTS Mean steps/d (+/- SE) differed significantly by sex (males, 10,849 (+/- 381; females, 9652 (+/- 289), age (junior students [years 9-11], 11,079 (+/- 330; senior students [years 12 and 13], 9422 (+/- 334), time of week (weekday, 12,259 (+/- 287; weekend day, 8241 (+/- 329), and mode of transportation to and from school (walkers, 13,308 (+/- 483; car transit users, 10,986 (+/- 435). Only 14.5% of students achieved at least 10,000 steps on every day during the monitoring period. CONCLUSION Daily step counts differed substantially by age, sex, time of week, and transportation mode to school.

Tracking refers to the tendency for individuals to maintain their rank in a group over time. The authors explored tracking of pedometer-determined physical activity. In October of 2000, 2003, and 2005, data of physical activity as steps per day were collected with sealed Yamax SW-200 pedometers (Tokyo, Japan) for 4 consecutive schooldays in 97 (46 boys and 51 girls) Swedish adolescents (mean ag...
متن کاملPhysical Activity Levels and Domains Assessed by Accelerometry in German Adolescents from GINIplus and LISAplus
BACKGROUND Physical activity (PA) is a well-known and underused protective factor for numerous health outcomes, and interventions are hampered by lack of objective data. We combined accelerometers with diaries to estimate the contributions to total activity from different domains throughout the day and week in adolescents. METHODS Accelerometric and diary data from 1403 adolescents (45% male,...
متن کاملDriving down daily step counts: the impact of being driven to school on physical activity and sedentary behavior.
This study investigated whether being driven to school was associated with lower weekday and weekend step counts, less active out-of-school leisure pursuits, and more sedentary behavior. Boys aged 10-13 years (n = 384) and girls aged 9-13 years (n = 500) attending 25 Australian primary schools wore a pedometer and completed a travel diary for one week. Parents and children completed surveys cap...
متن کاملIs wearing a pedometer associated with higher physical activity among adolescents?
OBJECTIVE To examine whether wearing a pedometer was associated with higher objectively-measured physical activity (PA) among adolescents independent of other behavior change strategies, and whether this association differed by sex or day of wear. METHOD In a parallel-group population-based cohort study, 892 adolescents (43.4% male, mean±SD age, 14.5±0.5years) from Eastern England were recrui...
