Physical environmental factors related to physical activity in adults: identifying the contribution of 'activity-friendly' environments next to psycho-social factors and demographics

The objectives of this project are to investigate whether adults who live in 'high walkable' neighbourhoods are more physically active, than those living in less 'walkable' neighbourhoods, including SES as a mediator, and comparing these results with analogue studies in the US (Sallis, NQLS-study) and Australia (Owen, PLACE-study).
