Active travel may have positive effects on health outcomes , but there is little robust evidence to date of the effectiveness of active transport interventions for reducing obesity .
BACKGROUND Increasing active travel ( primarily walking and cycling ) has been widely advocated for reducing obesity levels and achieving other population health benefits .
However , the strength of evidence underpinning this strategy is unclear .
This study aim ed to assess the evidence that active travel has significant health benefits .
Physical activity and cause-specific mortality in men: Further evidence from the Whitehall study
Reports of studies relating physical activity to stroke and cancer sub-types indicate inconsistent findings . Some are hampered by low statistical power , owing to a low number of events , and a failure to adjust for potential confounding variables . The purpose of this study was to relate physical activity to 12 mortality endpoints in a prospect i ve cohort study of 11,663 men aged 40–64 years who responded to an enquiry about travel activity during a baseline medical examination conducted between 1967 and 1969 . During 25 years of follow-up there were 4672  deaths .  Travel activity  was inversely related to mortality attributable to all-causes , coronary heart disease , respiratory disease and lung cancer , whereas the association with stroke was positive . There was evidence for attenuation of some of these associations on adjustment for potentially confounding variables . Our simplistic measure of physical activity may , in part , explain the weak associations seen
