Journal ArticleDOI
Perceived neighborhood environmental attributes associated with walking and cycling for transport among adult residents of 17 cities in 12 countries: the IPEN study
Jacqueline Kerr,Jennifer A. Emond,Hannah Badland,Rodrigo Siqueira Reis,Olga L. Sarmiento,Jordan A. Carlson,James F. Sallis,Ester Cerin,Ester Cerin,Kelli L. Cain,Terry L. Conway,Grant Schofield,Duncan J. Macfarlane,Lars Christiansen,Delfien Van Dyck,Rachel Davey,Ines Aguinaga-Ontoso,Deborah Salvo,Deborah Salvo,Takemi Sugiyama,Neville Owen,Josef Mitáš,Loki Natarajan +22 more
TL;DR: Many perceived environmental attributes supported both cycling and walking; however, highly walkable environments may not support cycling for transport, and these findings can guide the implementation of global health strategies.
Journal ArticleDOI
International variation in neighborhood walkability, transit, and recreation environments using geographic information systems: the IPEN adult study.

Macfarlane,Neville Owen,James F. Sallis +21 more
TL;DR: Results show that comparable measures can be created across a range of cultural settings revealing profound global differences in urban form relevant to physical activity, and allow cities to be ranked more precisely than previously possible.

TL;DR: This study was designed to inform evidence-based international and country-specific physical activity policies and interventions to help prevent obesity and other chronic diseases that are high in developed countries and growing rapidly in developing countries.
Journal ArticleDOI
International comparisons of the associations between objective measures of the built environment and transport-related walking and cycling: IPEN adult study

TL;DR: Across 14 diverse cities and countries, living in more densely populated areas, having a well-connected street network, more diverse land uses, and having more parks were positively associated with transport-related walking and/or cycling.
Journal ArticleDOI

TL;DR: The findings should encourage policymakers, governments, and local and national stakeholders to take action to facilitate an increase in the physical activity levels of young people across Europe.
