cAdjusted for Street Smart Walk Score, gender, age
dAdjusted for all predictor variables listed in this table
eAdjusted for all predictor variables listed in this table with the exception of crime, since crime was not associated with steps (n/day) at p ≤ 0.2 in bivariate analyses
f Neighbourhood Environment Walkability Scale—abbreviated (NEWS-A) Subscale F: Aesthetics (four-point scale); reverse coded so that higher score indicates better walkability
gNEWS-A Subscale H: Crime (four-point scale); reverse coded so that higher score indicates better walkability
hTotal number; measured with the Functional Comorbidity Index
iAssessed as part of the 4-m walk (usual pace) component of the Short Physical Performance Battery
jVery much like to walk (5 on a 5-point scale) vs. less than very much liking to walk (1–4 on a 5-point scale)
kAssessed by the Ambulatory Self-Confidence Questionnaire
