Note: MVPA= moderate-vigorous physical activity. Continuous measures reported as mean ± SD and median [interquartile range] and analyzed by walkability group with two-sample t-tests and Wilcoxon rank-sum tests. Categorical variables were reported as n (%) and analyzed by walkability group with the chi-square test of independence.
