Unstandardized beta (b) coefficients (slope) adjusted for baseline sex, age, children, education, income, and employment status. A positive b reflects a decreasing difference in negative exposure and increasing difference in positive exposure is associated with more physical activity. A negative b reflects a decreasing difference in negative exposure and increasing difference in positive exposure is associated with less physical activity.
Relative difference exposure = [Street integration (follow-up) – street integration (baseline)] / street integration (baseline).
Absolute difference exposure = [Street integration (follow-up) – street integration (baseline)].
MPA: moderate-intensity physical activity. VPA: vigorous-intensity physical activity. MVPA: moderate-to-vigorous intensity physical LW: leisure walking. TW: transportation walking.
*Statistically significant (p < .05) association between street integration exposure and follow-up physical activity.
^aThe follow-up physical activity variables are unstandardized residuals estimated from a linear regression adjusting for baseline physical activity and elapsed time between completed baseline and follow-up surveys.
