  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. Each index was tested in a separate model;
  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. Bolded cells with × symbol depict significant associations that were categorized as ‘mismatches’ between the location reflected in the index and activity variable, there were 2 mismatches in total;
  4. We did not label associations involving overall activity variables because there were no hypotheses around overall activity- these results are presented for context;
