  1. a Values shown in the table are the means (95% confidence intervals) of the average daily pattern metric adjusted for wear time and demographic factors (age, gender, race/ethnicity, and education) and weighted to account for selection due to factors related to device-wear consent. P-values correspond to tests for differences in means across levels of the factors. The selection model used to generate weights was based on all covariates shown in Table 1. ActiGraph-wear participants missing covariates that were used in the selection model (N = 44 participants) were excluded from the above weighted summary table
  2. bPA classified based on OPACH cut-points [25]: Sedentary Time (VM < = 18 counts/15 s); LPA (VM is 19 through 518 counts/15 s); and MVPA (VM is > 518 counts/15 s)
