Archsurg.jamanetwork.com: Jan 2013

Objective  To examine the relationship between race and lung cancer mortality and the effect of residential segregation in the United States.

Design  A retrospective, population-based study using data obtained from the 2009 Area Resource File and Surveillance, Epidemiology and End Results program.

Setting  Each county in the United States.

Patients  Black and white populations per US county.

Main Outcome Measures  A generalized linear model with a Poisson distribution and log link was used to examine the association between residential segregation and lung cancer mortality from 2003 to 2007 for black and white populations. Our primary independent variable was the racial index of dissimilarity. The index is a demographic measure that assesses the evenness with which whites and blacks are distributed across census tracts within each county. The score ranges from 0 to 100 in increasing degrees of residential segregation. Read more
