Resumo
There is growing evidence that longer travel time by private car poses physical and mental risks. Individual-level
obesity and diabetes, two of the main public health challenges in low- and middle-income contexts, could be
associated to city-level travel times by car. We used individual obesity and diabetes data from national health
surveys from individuals in 178 Latin American cities, compiled and harmonized by the SALURBAL project. We
calculated city-level travel times by car using the Google Maps Distance Matrix API. We estimated associations
between peak hour city-level travel time by car and obesity and diabetes using multilevel logistic regression
models, while adjusting for individual characteristics and other city-level covariates. In our study we did not
observe a relationship between city-level peak-hour travel time by car and individual obesity and diabetes, as
reported in previous research for individual time spent in vehicles in high-income settings. Our results suggest
that this relationship may be more complex in Latin America compared to other settings, especially considering
that cities in the region are characterized by high degrees of population density and compactness and by a higher
prevalence of walking and public transportation use.
