Adherence
Walkable urban form (density, connectivity) has weaker or non-significant associations with physical activity and BMI for disadvantaged groups compared to advantaged groups.
Urban planners should not assume walkability alone will solve obesity in low-income areas. Interventions must address additional barriers like car ownership, safety, and access to destinations.
ModerateQualifiesMEDIUM confidence
A large study in New York City found that walkability indicators were not associated with body mass index among individuals with lower SES, black race, or Hispanic ethnicity.
Why this rating
Based on mixed findings in the review, with some studies showing no association.

- Increasing access to supermarkets and places to exercise, along with improving neighborhood safety, are promising strategies to reduce obesity-related health disparities in disadvantaged populations.Good
- Disadvantaged populations (low SES, Black, Hispanic) are disproportionately exposed to obesogenic built environment characteristics, including fewer supermarkets, more convenience stores, and less safety.Good
