METHODS: Objective environment, body size (body mass index (BMI), waist circumference (WC)), and sedentary time and physical activity data were collected from a random selection of 2033 adults aged 20-65 years living in 48 neighbourhoods across four New Zealand cities.

RESULTS AND DISCUSSION: Street connectivity and neighborhood destination accessibili..
