“…We developed and calibrated an ABM which enabled a policy-oriented exploration of commuting patterns in an LMIC urban setting, characterized by high levels of necessity-based walking and inequality. Grounded in the unique context of Bogota, Colombia, our systems approach to understanding and promoting physical activity in LMICs directly addresses recent calls within the eld [14,54]. Moreover, while our model integrated factors normatively represented in transport-related decision-making models, such as spatial accessibility and the nancial means to use varying forms of transit, our model uniquely attended to other system-level in uences that feature within commuters' decision-making process, such as personal safety from crime and peer in uences.…”

Background: Transportation policies can impact health outcomes while simultaneously promoting social equity and environmental sustainability. We developed an agent-based model (ABM) to simulate the impacts of fare subsidies and congestion taxes on commuter decision-making and travel patterns. We report effects on mode share, travel time and transport-related physical activity (PA), including the variability of effects by socioeconomic strata (SES), and the tradeoffs that may need to be considered in the implementation of these policies in a context with high levels of necessity-based physical activity. Methods: The ABM design was informed by local stakeholder engagement. The demographic and spatial characteristics of the in-silico city, and its residents, were informed by local surveys and empirical studies. We used ridership and travel time data from the 2019 Bogota Household Travel Survey to calibrate and validate the model by SES. We then explored the impacts of fare subsidy and congestion tax policy scenarios. Results: Our baseline model reproduced commuting patterns observed in Bogotá. Its outputs were also robust to sensitivity analyses. At the city-level, congestion taxes fractionally reduced car use, including among mid-to-high SES groups but not among low SES commuters. Neither travel times, or physical activity levels were impacted at the city-level or by SES. Comparatively, fare subsidies promoted city-level public transit (PT) ridership, particularly under a ‘free-fare’ scenario, largely through reductions in walking trips. ‘Free fare’ policies also led to a large reduction in very long walking times, and an overall reduction in the commuting-based attainment of physical activity guidelines. Differential effects were observed by SES, with free fares promoting PT ridership primarily among low-and-middle SES groups. These shifts to PT reduced median walking times among all SES groups, particularly low-SES groups. Moreover, the proportion of low-to-mid SES commuters meeting weekly physical activity recommendations decreased under the free fare policy, with no change observed among high-SES groups. Conclusions: Transport policies can differentially impact SES-level disparities in necessity-based walking and travel times. Understanding these impacts is critical in shaping transportation policies that balance the dual aims of reducing SES-level disparities in travel time (and time poverty) and the promotion of choice-based physical activity.

“…In particular, walking for transport is part of everyday life in communities where there are low levels of income and high levels of informal work (9,10) (walking may be a light-intensity activity or a moderate-intensity activity, depending on age and fitness [11]). In the city of Bogotá in Colombia, for example, many people participate in more than 300 min of light-intensity physical activity per day (12) and spend more than 180 min traveling to and from work each day (13). To the best of our knowledge, there are no cohort studies about the longitudinal associations between physical activity and obesity in adults in Colombia or elsewhere in Latin America.…”

Purpose To investigate longitudinal associations between physical activity levels and obesity in adults in Colombia, where participation in large amounts of light-intensity physical activity is a necessity for many people. Methods Participation in moderate- and vigorous-intensity physical activity was assessed from 2005 to 2009 and obesity was assessed from 2011 to 2019 in men and women from the Prospective Urban Rural Epidemiology (PURE) study. Total physical activity level was categorized as low (<600 MET-min/week), medium (600-3,000 MET-min/week), or high (>3,000 MET-min/week) (600 MET-min/week is equivalent to 150 minutes of moderate activity or 75 minutes of vigorous activity per week). Obesity was defined as body mass index ≥30 kg/m2. Analyses were adjusted for age, sex, smoking, socioeconomic status, diet, alcohol, sedentary time, and sleep. Results The main analysis included 3,086 men and women aged 51 ± 9 years at baseline (mean ± SD). Compared to the low physical activity group, the odds ratio (95% confidence interval) for obesity was 0.67 (0.53, 0.85) in the medium physical activity group, and 0.78 (0.62, 0.98) in the high physical activity group after adjustment for potential confounders. Smoking is probably a major confounder and it is noteworthy that similar associations were observed in participants who reported never smoking. Conclusions The PURE study is the only prospective cohort study in Colombia. The present analysis is important because it suggests that even the busy people of Colombia could substantially reduce their risk of obesity by participating in moderate- and vigorous-intensity physical activity.
