Event Description
Join the
Department of Epidemiology and Biostatistics for the dissertation defense "Streetscape Virtual Audits Across the Americas: Measurement, Validity, and Bias" of
Dustin Fry, MPH.
This dissertation describes the development of a novel measure of neighborhood physical disorder applicable for use in health studies in Latin American cities. First, patterns of Google Street View image availability within Latin American cities is described. Second, virtual audits were conducted on street segments in five urban areas in the United States (New York, NY; Philadelphia, PA; Jackson, MS; San Antonio, TX; and the Rio Grande Valley, TX) and four in Latin America (Mexico City, MX; Bogota, CO; Belo Horizonte, BR; and Santiago, CL). Next, a measure of neighborhood physical disorder was adapted from this audit data, and predictors of individual perceptions of disorder by trained auditors are explored. Finally, predictive validity of the measure was assessed by examining associations between neighborhood physical disorder at the subcity level and life expectancy at birth and at age 45, comparing relationships between regions.
