Abstract Studies investigating the built environment (BE) correlates of physical activity (PA) suggest that their relation may be context-specific. The US Walkability Index is considered a good predictor of PA in high income countries; however, their adequacy to middle income countries such as Mexico must be studied in consideration to more specific BE elements; elements such as aesthetics, proximity of parks, road and public safety are relevant BE features of PA. The purpose of this study is to identify the contextually-relevant BE measures that best define walking-friendly environments in Mexico and assess their correlates to PA among Mexicans.The study has three phases. a) the identification of contextually-relevant perceived BE constructs for measuring PA in the Mexican context as reported in peer-reviewed literature in urban planning, urban design and architecture. b) the face validation of the constructs of relevance with public health, PA, urban planning and architecture leaders in Mexico. Third, the adaptation of current instruments such as the Abbreviated Neighborhood Environment Walkability Scale (A-NEWS). Relevant BE constructs for PA among Mexicans were identified: public spaces realms, including parks, streets and plazas, as well as other pedestrian spaces, are relevant measures of BE in relation to PA. Safety from transit and public safety were contextually-appropriate variables. Obstacles for pedestrians (e. g. street vendors, public telephones) emerged as other important BE elements. This study drew on scientific evidence and the expertise of local leaders to identify key BE constructs for defining the characteristics of walking friendly environments in Mexican cities.
