MVPA was calculated from participant reports on the frequency and duration of three types of PA (vigorous or moderate intensity without walking, and walking) per week. Each network buffer was analysed separately. Bold shows significance p<0.05.
*Model 1: crude model.
†Model 2: gender, age and body mass index were adjusted.
‡Model 3: Model 2, sedentary time, disease treatment, educational years and residental area were adjusted.
§Land slope in the 400 m network buffer was categorised into ‘low’ (<7.38°), ‘middle’ (7.38°–<11.53°) and ‘high’ (≥11.53°).
¶Land slope in the 800 m network buffer was categorised into ‘low’ (<8.22°), ‘middle’ (8.22–<13.06°) and ‘high’ (≥13.06°).
MVPA, moderate-to-vigorous physical activity; PR, prevalence ratio.
