  1. aAll models were adjusted for participant age, sex, race/ethnicity, parent education, study design factors, number of days of accelerometer wear, number of school days, and accelerometer wear time in each location;
  2. bValues are standardized regression coefficients (β) and standard errors (SE), with both the independent and dependent variables standardized to have a mean of zero and standard deviation of 1. These values represent the standardized increases (positive coefficients) or decreases (negative coefficients) in the outcome variables per standard deviation increase on the index variable. Benchmarks for interpreting the magnitude of the coefficients were small (β = .10), small-to-moderate (β = .20), and moderate (β = .30);
  3. cSociodemographic variables were analyzed first as a separate group of predictors without the index scales in the models to obtain these values and show general associations between sociodemographic correlates of physical activity and the outcome variables;
  4. *P < 0.05;
  5. **P < 0.01;
  6. dVariable was reverse coded when calculating index score
