BACKGROUND: Most youth fail to achieve 60 minutes of moderate-to-vigorous physical activity (MVPA) daily while engaging in excessive amounts of sedentary behaviors. The objective of this investigation was to identify modifiable factors associated with meeting MVPA recommendations or engaging in greater than 55% of observed time sedentary. METHODS: Youth (N = 1005, 10.5 yrs, 52% girls) wore accelerometers with daily minutes of MVPA (≥ 2296 counts · min(-1)) classified as ≥ 60 min s/d vs. < 60 min/d of MVPA. Sedentary behavior (< 100 counts · min(-1)) was classified as < 55% or ≥ 55% of total wear-time. Two-level random effects logit survival models for repeated events (days of monitoring) examined the association of psychosocial self-report measures and demographic characteristics to meeting the MVPA recommendation and spending ≥ 55% of time sedentary. RESULTS: Wednesdays, Thursdays, and Sundays were associated with a decreased likelihood of meeting MVPA recommendations relative to Mondays. Wednesday thru Sunday were associated with a decreased likelihood of spending ≥ 55% of time sedentary. Being a boy, receiving transportation, and fewer reported barriers to physical activity were associated with meeting MVPA recommendations. CONCLUSIONS: Relatively few youth are engaging in recommended levels of physical activity. Provision of transportation and reduction of barriers to physical activity are relevant targets for physical activity promotion.
