^aBased on final analytic sample (n = 151)
^bDenisty variables based on participant centric buffers of varying size and types (Euclidean [EB] and network [NB]). Buffer sizes and types per built environment characteristic were defined based on a sensitivity analysis (refer to Additional file 1 online appendix). Street connectivity (500 EB); park, Metrolink, grocery store, and convenience store (1000 EB); Metrobus and all-transit (1500 EB); fast food (1500NB). Density variables dichotomized at the median count of each variable within the determined buffer size and type into high/low. Park, Metrolink, grocery store, convenience store (1); fast food (4); street connectivity, Metrobus, all-transit (21)
^cDistance variables dichotomized at the median distance in meters and split into high/low distance. Parks (1325.30); transit stops (972.42); grocery stores (1232.12); convenience stores (1344.60); and fast food (865.38)
Note: All distances and buffer radii are measured in meters
