*Quartile 1 (least walkable) served as the reference; GIS-derived walkability index quartiles: <−1.5, ≥1.5, <−0.3, ≥−0.3, <1.1, ≥1.1; Walk Score quartiles: <22, ≥22, <48, ≥48, <68, ≥68.
†Model 1: unadjusted; model 2: adjusted for age, sex and body mass index; model 3: adjusted for age, sex, body mass index, married/common law, income, children, immigrant and mood disorder; model 4: adjusted for age, sex, body mass index, married/common law, income, children, immigrant, mood disorder, perceived health, ever smoker and season.
‡Rural location was not included in the final multivariate models as it was correlated with both GIS-derived walkability and the Walk Score.
