*P values for omnibus tests of significance (ANOVA for continuous outcomes, Chi-square for dichotomous outcomes) set at ≤ .01. Superscripts indicate significantly different groups for those variables in which the omnibus test reached statistical significance
†Social modeling = observing others walking or cycling in one’s neighborhood
§SPPB = Short Physical Performance Battery
# n = 1306, due to delayed start in accelerometry data collection and elimination of data with technical errors
