Sociocultural perceptions of walkability in Mexican American neighborhoods: Implications for policy and practice

Health Disparities, Transportation Equity and Complete Streets: a Case Study of a Policy Development Process through the Lens of Critical Race Theory

Historic disinvestment in transportation infrastructure is directly related to adverse social conditions underlying health disparities in low-income communities of color. Complete Streets policies offer a strategy to address inequities and subsequent public health outcomes. This case study examines the potential for an equity-focused policy process to address systemic barriers and identify potential measures to track progress toward equity outcomes. Critical race theory provided the analytical framework to examine grant reports, task force notes, community workshop/outreach activities, digital stories, and stakeholder interviews. Analysis showed that transportation inequities are entrenched in historically rooted disparities that are perpetuated in ongoing decision-making processes. Intentional efforts to incorporate equity into discussions with community members and representatives contributed to explicit equity language being included in the final policy. The potential to achieve equity outcomes will depend upon policy implementation. Concrete strategies to engage community members and focus city decision-making practices on marginalized and disenfranchised communities are identified.

Differences in social and physical dimensions of perceived walkability in Mexican American and non-hispanic white walking environments in Tucson, Arizona

INTRODUCTION

Physical activity patterns within the U.S. vary greatly across ethnicity, with data generally indicating lower rates among Hispanic/Latino adults. At the same time, Hispanic/Latino pedestrians face higher rates of injury and fatalities. Despite the importance of supportive physical activity environments on both health and safety outcomes, limited attention has been paid to ethnic or cultural differences in perceptions of supportive environments for walking. To fill this gap, we explore differences in physical and social environment contributors to perceived walkability between pedestrians in predominantly (> 70%) Mexican American and predominantly non-Hispanic white areas in Tucson, Arizona.

METHODS

In early 2017 the research team conducted brief on-street intercept interviews with pedestrians (N = 190) to learn about the environmental attributes associated with pedestrian perceptions of walkability. Study locations were matched for similar physical walkability metrics, income, and poverty rates. Consensus-based thematic coding identified 14 attributes of the built and social environment that contributed, positively and negatively, to perceptions of walkability.

RESULTS

Attributes of the social environment, both positive (i.e., social interaction, social cohesion, and community identity) and negative (i.e., crime/security), were more frequently expressed as components of walkability in Mexican American study areas while physical environment attributes (i.e., infrastructure, street crossings, and aesthetics) were more frequently mentioned in non-Hispanic white areas.

CONCLUSIONS

Contributors to perceived walkability in non-Hispanic white study areas were largely consistent with existing built environment-focused walkability metrics. Differences seen in Mexican American areas suggest a need to better understand differences across populations, expand the construct of walkability to consider social environment attributes, and account for interactions between social and physical environments. Results highlight the need for collaboration between public health and planning professionals, to evaluate walkability using culturally relevant measures that account for the social environment, particularly in Mexican American and other communities of color.
