  1. MVPA moderate-to-vigorous physical activity, OR odds ratio, IRR incidence rate ratio, B beta, CI confidence interval. Proximity was defined as the negative of the natural logarithm of the road network distance in metres from the weighted population centroid of the unit postcode of residence to the nearest motorway junction. Analyses were adjusted for age, gender, home ownership, car ownership, work status and time lived in neighbourhood
