Individual- and neighborhood-level characteristics of participants and unadjusted associations with NDVI (N = 636). Notes: Chi-Sq and ANOVA associations by low (0.06–0.19), medium (0.19–0.23), and high (0.23–0.36) tertiles of NDVI within a 100 m radius. Area population density defined at the block group level.
