Home versus nonhome neighborhood: quantifying differences in exposure to the built environment.

ABSTRACT:

Background

Built environment and health research have focused on characteristics of home neighborhoods, whereas overall environmental exposures occur over larger spatial ranges.

Purpose

Differences in built environment characteristics were analyzed for home and nonhome locations using GPS data.

Methods

GPS data collected in 2007-2008 were analyzed for 41 subjects in the Seattle area in 2010. Environmental characteristics for 3.8 million locations were measured using novel GIS data sets called SmartMaps, representing spatially continuous values of local built environment variables in the domains of neighborhood composition, utilitarian destinations, transportation infrastructure, and traffic conditions. Using bootstrap sampling, CIs were estimated for differences in bu
