NW: normal weight; OW: overweight; F: female, M: male; data are presented as mean ± SD followed by median (interquartile range); weekly bout-related MVPA: minutes/week spent engaging in moderate-to-vigorous intensity physical activity ≥10 minutes in duration; SWA: SenseWear armband; PPAQ: Paffenbarger Physical Activity Questionnaire. % Within a column, means sharing the same superscript are not significantly different from each other, after adjusting for clinic, age, race, marital status, children in household, full time student/working status, and daily wear time (p < 0.05).
