Abstract
Disparities in cancer risk exist between ethnic groups in the United States. These disparities often result from differential access to healthcare, differences in socioeconomic status and differential exposure to carcinogens. This study uses cancer incidence data from the population based Texas Cancer Registry to investigate the disparities in digestive and respiratory cancers from 2000 to 2008. A Bayesian hierarchical regression approach is used. All models are fit using the INLA method of Bayesian model estimation. Specifically, a spatially varying coefficient model of the disparity between Hispanic and Non-Hispanic incidence is used. Results suggest that a spatio-temporal heterogeneity model best accounts for the observed Hispanic disparity in cancer risk. Overall, there is a significant disadvantage for the Hispanic population of Texas with respect to both of these cancers, and this disparity varies significantly over space. The greatest disparities between Hispanics and Non-Hispanics in digestive and respiratory cancers occur in eastern Texas, with patterns emerging as early as 2000 and continuing until 2008.
Highlights
Disparities in cancer incidence and mortality exist between racial and ethnic groups in the United States and worldwide (Du et al, 2007; Elmore et al, 2005; Harper et al, 2009; Hun et al, 2009; McKenzie, Ellison-Loschmann & Jeffreys, 2010; Siegel, Naishadham & Jemal, 2012; Vainshtein, 2008)
The goal of this paper is to investigate the spatial variation in cancer incidence disparities between Hispanic and non-Hispanic populations of the state of Texas between 2000 and 2008 and attempt to identify geographic clusters of
The proportion of the work force in construction is positively associated with respiratory cancer risk in the three of the models, potentially suggesting an occupation-specific risk pattern
Summary
Disparities in cancer incidence and mortality exist between racial and ethnic groups in the United States and worldwide (Du et al, 2007; Elmore et al, 2005; Harper et al, 2009; Hun et al, 2009; McKenzie, Ellison-Loschmann & Jeffreys, 2010; Siegel, Naishadham & Jemal, 2012; Vainshtein, 2008) The causes of these disparities have been suggested to be rooted in different levels of socioeconomic status (SES), access to medical care, differential exposure to carcinogenic materials and differential treatment by medical staff of racial and ethnic minorities (Krieger, 2005; Sarfati et al, 2006; Schootman et al, 2010).
