Comparing local availability and
accessibility to healthy foods
across countries: A case study in
Madrid (Spain) and Baltimore (US)

Background
o Diet is a cardiovascular risk factor influenced
by the local food environment
o Local food environments are a good example
of a mass influence on population diets
o Inconsistencies around social gradients in
contextual healthy food availability exist
between US and Europe-based studies

Aim
To understand cross-national differences in the
local food environment between Madrid and
Baltimore by comparing an average neighborhood
in each city in terms of food store types,
availability, and accessibility to healthy foods.

Methods
Study context
We selected one neighborhood (~15000 pop.) in
each city selecting median areas in terms of:
• Educational level
• Aging
• Segregation
• Urban form
http://hhhproject.eu
Methods
Variables
• Availability
• Field observations using NEMS-s audit tool
• “Healthy Food Availability Index” (0-28.5)
• “Fruit&Vegetables Availability index” (0-10)
• Accessibility
• Pedestrian network analysis
• Walking distance of 200m, 400m, 800m

Conclusions
Our results may help promoting intervention
from local city agencies to allocate resources
to improve existing small-sized food stores
and public markets, and to improve walkable
urban environments.
