Background
An increasing number of studies have examined
associations of neighbourhood environmental attributes
with physical activity.
To date, most studies on this topic have examined data
collected in a single country.
Non-significant or weak associations reported in singlecountry studies may be due partly to limited variation in
environmental attributes.
Multi-country studies can fill this methodological gap by
provide larger variance in environmental attributes.
Aims
Q1. To examine the strength and shape of associations
of perceived neighbourhood environmental
attributes with adults’ recreational walking using
data obtained from 12 countries
Q2. To examine whether these associations differ
across countries
IPEN Adult Study
The International Physical Activity and Environment
Network (IPEN) Adult Study was an observational, crosssectional, multi-country study, involving 13,745 adults aged
18–66 years from 12 countries (17 study sites).
Countries included: Australia (AUS; Adelaide), Belgium
(BEL; Ghent), Brazil (BRA; Curitiba), Colombia (COL;
Bogota), the Czech Republic (CZ; Olomouc, Hradec
Kralove), Denmark (DEN; Aarhus), Hong Kong (HK),
Mexico (MEX; Cuernavaca), New Zealand (NZ; North
Shore, Waitakere, Wellington, Christchurch), Spain (ESP;
Pamplona), the United Kingdom (UK; Stoke-on-Trent), and
the United States of America (USA; Baltimore, Seattle).
Outcome: Recreational Walking
Self-reported frequency (days/week) and duration
(minutes/week) of walking for recreation in the last week,
obtained from the International Physical Activity
Questionnaire (IPAQ; long version), were used.
Exposure: Neighbourhood Environment
Perceived neighbourhood environmental attributes were
determined using the Neighborhood Environment
Walkability Scale (NEWS).
The following 10 items were used:
• residential density score
• land use mix–access
• street connectivity
• infrastructure and safety
• aesthetics
• safety from traffic
• safety from crime
• few cul-de-sacs
• no major barriers
• proximity to parks
Analysis
Generalized Additive Mixed Models (GAMMs) were used
to estimate the strength and shape of associations of
perceived environmental attributes with recreational
walking. All analyses were conducted in R.
Main effects of environmental attributes on the outcome
(linear and curvilinear components) were examined for
the whole sample, adjusting for study site, sociodemographic covariates, and area-level SES.
Interaction effects were probed by computing the sitespecific association of a perceived environmental
attributed with the outcome via linear functions. Analyses
stratified by sites were conducted when significant.
Models
The following three models were examined:
Model 1: likelihood of any walking for recreation versus
no walking for recreation;
Model 2: frequency (days/week) of walking for recreation
among those reporting walking during the past week;
Model 3: duration (minutes/week) of walking for
recreation among those reporting walking during the past
week

Summary
Q1. To examine the strength and shape of associations
of perceived neighbourhood environmental
attributes with adults’ recreational walking
Of the 10 perceived environmental attributes examined,
seven were (either linearly or curvilinearly) positively
associated with at least one walking outcome.
Stronger evidence was obtained for Aesthetics, which was
associated with all three walking measures, with a larger
effect size (26% higher odds of walking for a unit increase).
Summary
Q1. To examine the strength and shape of associations
of perceived neighbourhood environmental
attributes with adults’ recreational walking
Results show some support for the importance of:
• Safety from crime (linear association)
• Proximity to parks (linear association)
• Residential density (curvilinear association)
• Land use mix (curvilinear association)
Summary
Q1. To examine the strength and shape of associations
of perceived neighbourhood environmental
attributes with adults’ recreational walking
Mixed findings were obtained for:
• Connectivity and Few cul-de-sacs (higher street
connectivity and many cul-de-sacs were both positively
associated with walking)
No linear/curvilinear associations were found for:
• Infrastructure and safety
• Safety from traffic
• No major barriers
Summary
Q2. To examine whether associations of environmental
attributes with recreational walking differ across
countries
Effect modification by study sites was found for aesthetics,
which was associated linearly with walking in 4 sites.
The associations observed were mostly consistent across
countries, suggesting the generalisability of the findings.
Conclusions
Associations of perceived neighbourhood environmental
attributes with adults’ walking for recreation may be
similar in environmentally, culturally diverse countries.
Aesthetics appears to be an important factor in whether
and how often adults walk for recreation.
Higher population density (but not excessively high) and
higher land use diversity seem to contribute to longer
duration of recreational walking.
Safe neighbourhoods (from crime) with parks may
facilitate recreational walking.
