Parks and greenspaces can enhance personal health in various ways, including among others, through psychological restoration and improved well-being. However, under certain circumstances, parks may also have adverse effects by providing isolated and hidden spaces for non-normative and crime-related activities. This study uses a survey conducted by the Development Bank of Latin America in a cross-sectional representative sample of 7,110 respondents in eleven Latin-American cities. We examine associations between self-reported park proximity with perceived social disorder (drug use/sales, gangs, prostitution and assault and/or crime), and whether these associations are modified by neighborhood characteristics (informal neighborhoods, poor street-lighting, abandoned buildings, illegal dumping). High self-reported park proximity was associated with lower perceptions of social disorder, but these associations were no longer significant following adjustment for neighborhood characteristics. Significant interactions were observed between park proximity and neighborhood characteristics suggesting that the likelihood of perceiving social disorder increases with high park proximity in informal neighborhoods and in the presence of certain neighborhood characteristics, such as poor street-lighting, abandoned buildings, and illegal dumping in residential streets. The differential associations between reported park proximity and perceived social disorder in different living environments highlight the importance of supportive social and physical infrastructure to maximize the restorative benefits of parks in all urban areas.

Walking for transportation is a common and accessible means of achieving recommended physical activity levels, while providing important social and environmental co-benefits. Even though walking in rapidly growing urban areas has become especially challenging given the increasing dependence on motorised transportation, walking remains a major mode of transportation in Latin American cities. In this paper we aimed to quantify self-reported walking for transportation in Mexico City, Bogota, Santiago de Chile, Sao Paulo, and Buenos Aires, by identifying both walking trips that are conducted entirely on foot and walking events involved in trips mainly conducted on other means of transportation (e.g. private vehicle, public transit) among individuals ≥5-years old. We show how walking-only trips account for approximately 30% trips in the analysed cities, and we evidence how the pedestrian dimension of mobility is largely underestimated if walking that is incidental to other transportation modes is not accounted for: when considering all walking events, we observed an increase between 73% and 217% in daily walking time. As a result, we estimated that between 19% and 25% of residents in these cities meet the WHO physical activity guidelines solely from walking for transportation. The results of the study also suggest that the promotion of public transportation in large Latin American cities can especially help certain population groups achieve the daily recommended levels of physical activity, while among low-income groups accessibility and safety seem to be the key challenges to be addressed.
