[BDSP. Notice produite par INIST-CNRS rsGR0x88. Diffusion soumise à autorisation]. Measurements of neighborhood exposures likely vary depending on the definition of "neighborhood" selected. This study examined the extent to which neighborhood definition influences findings regarding spatial accessibility to tobacco retailers among youth. We defined spatial accessibility to tobacco retailers (i.e., tobacco retail density, closest tobacco retailer, and average distance to the closest 5 tobacco retailers) on the basis of circular and network buffers of 400 m and 800 m, census block groups, and census tracts by using residential addresses from the 2008 Boston Youth Survey Geospatial Dataset (n=1,292). Friedman tests (to compare overall differences in neighborhood definitions) were applied. There were differences in measurements of youths'access to tobacco retailers according to the selected neighborhood definitions, and these were marked for the 2 spatial proximity measures (both P
