  1. The built environment and pedestrian injuries Principal investigator: Andrés Villaveces, Research Asst. Prof. Dept Epidemiology UNC, IPRC • Collaboration: • IPRC • - Department of Urban Planning (DR, Co-I) • - Department of environmental sciences • and engineering (MS Co-I) • - Instituto Cisalva , University of El Valle, Cali, Colombia (MIG CO-I) • - Transmilenio S.A. and Office of the Mayor Bogotá, Colombia (DR CO-I) UNC

  2. Aims • The purpose of this study is to evaluate the association of • changes in the characteristics of the built environment and pedestrian • Injuries in two cities in Colombia • Cross-sectional measurement of the association of pedestrian injuries • in relation to neighborhood diversity, density and design using the • Irvine-Minnesota inventory • Longitudinal measurement of the association of changes in the • built environment in two cities • 3. Use of TGIS to evaluate spatial and temporal risk of events

  3. Built environment: • Definition • Previous studies (mostly related to physical activity) • Measurement (Density, diversity, design) • Existing tools: 7 , use of Irvine-Minnesota Inventory • Focused on walking environments • Component for pedestrians and interaction with traffic • Component for perceptions of safety/crime other injuries) • Preliminary studies: • Injury data • Evaluation of interventions • Institutional experience • Pilot project funded

  4. Cali (Colombia) Bogotá (Colombia) Considerable urban modifications Few modifications Injury outcomes Injury outcomes Study design Data available Time 12 years Mortality data Data collection ??? • Analysis: Multi-level modeling, use of TGIS, Longitudinal follow-up?
