Target audience
City council public health and transport officers
The problem
Urban health studies usually focus on the differences between neighbourhoods in the same city; however, that approach lacks any assessment of the overarching forces affecting the city as a whole.
What we did and why
We compared differences in the walking environment between Madrid and Philadelphia. We used an audit tool called M-SPACES that measures, for each street segment;
Our study’s contribution
We found that Philadelphia’s streets had higher scores for function (physical attributes that supported walking) and safety, while Madrid streets had greater a greater proportion of streets having at least one walking destinations. These results are key to understand which elements of the built environment could be key to uncover mass influences that operate at the city level.
Impacts for city policy and practice
In order to understand which urban characteristics impact on physical activity and health, we need to understand what characterize our cities as a whole. In our study, Madrid is characterized by a higher proportion of daily walking destinations, while the streets of Philadelphia have better physical infrastructure for walking in the street.
Future studies should include attention to the potential impact of built environment characteristics at the city level.

Enhance cognitive health in older adult communities using the CAP approach: fostering Connectedness, feeling At home, and engaging in joyful Play. This community-centric model seeks to improve well-being and complements existing health resources systems, emphasizing the importance of building strong, supportive networks among older adults.

We examine how caregiving-related needs remain overlooked in walkability and Transit-Oriented Development strategies. Despite high levels of urban complexity, many transit-accessible areas lack essential caregiving-support places, particularly in vulnerable neighbourhoods. This spatial mismatch limits care-engaged individuals’ ability to chain trips, and access services, reinforcing mobility and social inequities. Our research highlights the need to integrate caregiving accessibility into planning frameworks to ensure that walkable cities are also inclusive and care-supportive.
