Activity spaces in studies of the environment and physical activity
A review and synthesis of implications for causality
Activity spaces are increasingly used to understand how people interact with their environment and engage in activity but their use may raise challenges regarding causal inference. The authors conducted a…
Can changing the physical environment promote walking and cycling?
A systematic review of what works and how
Environmental changes aimed at encouraging walking or cycling may promote activity and improve health, but evidence suggests small or inconsistent effects in practice. Understanding how an intervention works might help…
Causal pathways linking environmental change with health behaviour change
Natural experimental study of new transport infrastructure and cycling to work
Mechanisms linking changes to the environment with changes in physical activity are poorly understood. Insights into mechanisms of interventions can help strengthen causal attribution and improve understanding of divergent response…
Correlates of reported and recorded time spent in physical activity in working adults
Results from the commuting and health in Cambridge study
Background: The correlates of physical activity in adults are relatively well studied. However, many studies use self-reported ('reported') measures of activity and we know little about the possible differences between…
