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.


236 high school students (age 12–18 years) wore sealed pedometers for 5 consecutive days. Data were analyzed using generalizing estimating equations.


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.


Daily step counts differed substantially by age, sex, time of week, and transportation mode to school.
