  3. cadjusted for Street Smart Walk Score, gender, and age
  4. dadjusted for all variables listed in this table with the exception of vehicle availability, since vehicle availability was not associated with time spent in light physical activity (min/day) at p ≤ 0.2 in bivariate analyses
  5. eadjusted for all variables listed in this table with the exception of traffic, since traffic was not associated with time spent in MVPA (min/day) at p ≤ 0.2 in bivariate analyses
