SALURBAL assessed the association between obesity and education levels and explored potential effect modification of this association by city-level socio-economic development. This cross-sectional study used survey data collected between 2002 and 2017. The data included 53,186 adults over 18 years of age in one hundred seventy-six Latin American cities within eight countries (Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Mexico and Peru). Among women, education was protective of obesity regardless, whereas among men, it was only protective in cities with higher levels of development. These divergent results suggest the need for sex- and city-specific interventions to reduce obesity prevalence and inequalities.

To better understand the health impacts of transportation initiatives, we conducted a systematic review of longitudinal health evaluations involving: a) bus rapid transit (BRT); b) bicycle lanes; c) Open Streets programs; and d) aerial trams/cable cars. We also synthesized systems-based simulation studies of the health-related consequences of walking, bicycling, aerial tram, bus and BRT use.

Commute patterns and depression: Evidence from eleven Latin American cities

Although travel behavior is expected to influence personal health, few studies have examined associations with mental health. This study examines associations between commute patterns and mental health using survey data in 11 Latin American cities. The findings provide preliminary evidence that better access to mass transit systems and less congestion may be linked to better mental health among urban residents.

The food environment in Latin America: a systematic review with a focus on environments relevant to obesity and related chronic diseases

Rising obesity and increasing recognition of the food environment's role in creating and addressing this challenge has led to increased attention on this topic within scientific literature in recent years. This study reviews literature describing the food environment in Latin America and policies targeting the food environment (FEP), as well as analytic studies that investigate associations between the FEP and dietary behaviors, overweight/obesity and obesity related chronic diseases. Findings suggest that health claims on food packaging are prevalent and mostly misleading; there is widespread use of marketing strategies for unhealthy foods aimed at children; and food prices are lower for processed relative to fresh foods. More work is needed to better understand policy impacts over time and the impacts of food prices and digital marketing on diet and health.

Using community-based system dynamics modeling to understand the complex systems that influence health in cities: The SALURBAL study

This article describes the design, implementation, and results of a collaborative process designed to elucidate the complex systems that drive food behaviors, transport, and health in Latin American cities and to build capacity for systems thinking and community-based system dynamics (CBSD) methods among diverse research team members and stakeholders. During three CBSD workshops, 62 stakeholders from 10 Latin American countries identified 98 variables and a series of feedback loops that shape food behaviors, transportation and health, along with 52 policy levers. Our findings suggest that CBSD can engage local stakeholders, help them view problems through the lens of complex systems and use their insights to prioritize research efforts and identify novel solutions that consider mechanisms of complexity.

A Novel International Partnership for Actionable Evidence on Urban Health in Latin America: LAC-Urban Health and SALURBAL

This article describes the origins and characteristics of an interdisciplinary multinational collaboration aimed at promoting and disseminating actionable evidence on the drivers of health in cities in Latin America and the Caribbean: The Network for Urban Health in Latin America and the Caribbean and the Wellcome Trust funded SALURBAL (Salud Urbana en América Latina, or Urban Health in Latin America) Project. Both initiatives have the goals of supporting urban policies that promote health and health equity in cities of the region while at the same time generating generalizable knowledge for urban areas across the globe. The processes, challenges, as well as the lessons learned to date in launching and implementing these collaborations, are described. By leveraging the unique features of the Latin American region (one of the most urbanized areas of the world with some of the most innovative urban policies), the aim is to produce generalizable knowledge about the links between urbanization, health, and environments and to identify effective ways to organize, design, and govern cities to improve health, reduce health inequalities, and maximize environmental sustainability in cities all over the world.

Building a Data Platform for Cross-Country Urban Health Studies: the SALURBAL Study

Studies examining urban health and the environment must ensure comparability of measures across cities and countries. We describe a data platform and process that integrates health outcomes together with physical and social environment data to examine multilevel aspects of health across cities in 11 Latin American countries. We used two complementary sources to identify cities with ≥ 100,000 inhabitants as of 2010 in Argentina, Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Mexico, Nicaragua, Panama, and Peru. We defined cities in three ways: administratively, quantitatively from satellite imagery, and based on country-defined metropolitan areas. In addition to "cities," we identified sub-city units and smaller neighborhoods within them using census hierarchies. Selected physical environment (e.g., urban form, air pollution and transport) and social environment (e.g., income, education, safety) data were compiled for cities, sub-city units, and neighborhoods whenever possible using a range of sources. Harmonized mortality and health survey data were linked to city and sub-city units. Finer georeferencing is underway. We identified 371 cities and 1436 sub-city units in the 11 countries. The median city population was 234,553 inhabitants (IQR 141,942; 500,398). The systematic organization of cities, the initial task of this platform, was accomplished and further ongoing developments include the harmonization of mortality and survey measures using available sources for between country comparisons. A range of physical and social environment indicators can be created using available data. The flexible multilevel data structure accommodates heterogeneity in the data available and allows for varied multilevel research questions related to the associations of physical and social environment variables with variability in health outcomes within and across cities. The creation of such data platforms holds great promise to support researching with greater granularity the field of urban health in Latin America as well as serving as a resource for the evaluation of policies oriented to improve the health and environmental sustainability of cities.

Mortality and Life Expectancy in Latin American Cities

Life expectancy and causes of death vary greatly across urban areas in Latin America, and global and regional summaries of life expectancy and causes of death can hide significant variability across cities. Urban environments that differ across neighborhoods, cities, and countries can have a major impact on life expectancy and causes of death. Mortality and Life Expectancy in Latin American Cities presents the experiences of the SALURBAL project in harmonizing and describing mortality data across 366 cities in 10 countries.
