Walking to Work: The Roles of Neighborhood Walkability and Socioeconomic Deprivation.

BACKGROUND: There are few studies that aimed to find a relationship between transportation-related physical activity and neighborhood socioeconomic condition using a composite deprivation index. The purpose of this study is to assess the relationship of neighborhood walkability and socioeconomic deprivation with percentage of adults walking to work. METHODS: A walkability index and a socioeconomic deprivation index were created at block group-level. The outcome variable, percentage of adults who walk to work was dichotomized as < 5% of the block group walking to work low and ≥ 5% of the block group walking to work as high and applied logistic regression to examine the association of walkability and socioeconomic deprivation with walking to work. RESULTS: Individuals in the most walkable neighborhoods are almost 5 times more likely to walk to work than individuals in the least walkable neighborhoods (OR = 4.90, 95% CI = 2.80-8.59). After adjusting for neighborhood socioeconomic deprivation, individuals in the most walkable neighborhoods are almost 3 times more likely to walk to work than individuals in the least walkable neighborhoods (OR = 2.98, 95% CI = 1.62-5.49). CONCLUSIONS: Walkability (as measured by the walkability index) is a very strong indicator of walking to work even after controlling for neighborhood socioeconomic disadvantage.

Developing a research agenda for promoting physical activity in Brazil through environmental and policy change.

OBJECTIVE: To identify the highest priorities for research on environmental and policy changes for promoting physical activity (PA) in Brazil; to uncover any gaps between researchers' and practitioners' priorities; and to consider which tools, methods, collaborative strategies, and actions could be useful to moving a research agenda forward. METHODS: This was a mixed-methods study (qualitative and quantitative) conducted by Project GUIA (Guide for Useful Interventions for Activity in Brazil and Latin America) in February 2010-January 2011. A total of 240 individuals in the PA field (186 practitioners and 54 researchers) were asked to generate research ideas; 82 participants provided 266 original statements from which 52 topics emerged. Participants rated topics by "importance" and "feasibility;" a separate convenience sample of 21 individuals categorized them. Cluster analysis and multidimensional scaling were used to create concept maps and pattern matches. RESULTS: Five distinct clusters emerged from the concept mapping, of which "effectiveness and innovation in PA interventions" was rated most important by both practitioners and researchers. Pattern matching showed a divergence between the groups, especially regarding feasibility, where there was no consensus. CONCLUSIONS: The study results provided the basis for a research agenda to advance the understanding of environmental and policy influences on PA promotion in Brazil and Latin America. These results should stimulate future research and, ultimately, contribute to the evidence-base of successful PA strategies in Latin America.

Objective.

Objetivo. Identificar las máximas prioridades en la investigación sobre cambios ambientales y de políticas para promover la actividad física en el Brasil; descubrir las posibles disparidades en las prioridades de los investigadores y las de los profesionales; y evaluar qué herramientas, métodos, estrategias colaborativas y acciones podrían ser útiles para el avance de un programa de investigación. Métodos. Fue un estudio de metodología mixta (cualitativa y cuantitativa) llevado a cabo por el Proyecto GUIA (Guía para intervenciones útiles de actividades físicas en Brasil y Latinoamérica) entre febrero de 2010 y enero de 2011. Se pidió a 240 personas del campo de la actividad física (186 profesionales y 54 investigadores) que generaran ideas para la investigación; 82 de los participantes aportaron 266 afirmaciones originales de las que surgieron 52 temas. Los participantes puntuaron los temas en función de su "importancia" y "viabilidad" y otra muestra de conveniencia formada por 21 personas los clasificó. Se usó el análisis por conglomerados y el escalonamiento pluridimensional para crear mapas conceptuales y concordancias de patrones. Resultados. Con la elaboración de mapas conceptuales surgieron cinco conglomerados diferenciados y, de ellos, el que tanto los profesionales como los investigadores consideraron más importante fue "eficacia e innovación en las intervenciones de actividad física". La concordancia de patrones indicó una divergencia entre los grupos, especialmente con respecto a la viabilidad, sobre la que no hubo consenso. Conclusiones. Los resultados del estudio sirvieron de base para un programa de investigación con el que avanzar en la comprensión de la influencia que el ambiente y las políticas ejercen sobre la promoción de la actividad física en el Brasil y en América Latina. Estos resultados deben fomentar la futura investigación y, en último término, aumentar la base de evidencia sobre estrategias fructíferas de actividad física en América Latina
