This study reveals the connection between urban form, mode-specific physical activity, and healthcare costs, as well as the indirect associations between residential choices, attitudes, and health outcomes. The results suggest that altering behaviors and retrofitting neighborhoods can lead to lower healthcare costs.
Evidence connecting health care expenditures with physical activity and built environment is rare. We examined how detailed urban form relates to mode specific moderate-to-vigorous physical activity (MVPA) and health care costs-controlling for transit access, residential choices/preferences, sociodemographic factors. We harness high resolution data for 476 participants in the Rails and Health study on health care costs, mode specific MVPA, parcel-level built environment, and neighborhood perception surveys. To account for dependencies among outcomes, structural equation modeling framework is used. A 1% increase in bike, walk, and transit-related MVPA was associated with lower health care costs by -0.28%, -0.09%, and -0.27% respectively. A one-unit increase in neighborhood walkability index correlates with a 6.48% reduction in health care costs. Indirect associations between residential choices, attitudes, and health outcomes through MVPA were also observed. The results suggest the potential to alter behaviors and lower health care costs through retrofitting neighborhoods.
