  1. exp(b) = antilogarithm of regression coefficient; exp.(95% CI) = antilogarithms of 95% confidence intervals; p = p value. Values of exp.(b) are to be interpreted as the proportional increase (or decrease) in objectively-assessed moderate-to-vigorous physical activity associated with a 1 unit increase of the environmental attribute. Values >1.00 indicate a positive associations (increase), while values <1.00 indicate a negative association (decrease). All regression coefficients were adjusted for adolescents’ age, sex, parental/custodian marital status, highest educational attainment in the household, length of residence in the neighborhood, administrative-unit socio-economic status, accelerometer wear time, and study site. Models accounted for administrative-unit and school clustering. Statistically significant (p < .05) environmental correlates are in bold
