County-level socioeconomic status and cancer rates in Texas, 2001-2005.
Previous studies have shown that a person's socioeconomic status (SES) (a proxy measure that can incorporate income, wealth, education, and occupation) is associated with cancer incidence and mortality. Examining variation in cancer rates by SES can help identify health disparities and target areas for cancer control activities. The Texas Cancer Registry (TCR) collects data on every newly diagnosed case of cancer in Texas, including personal and demographic data, but does not collect data related directly to SES. Using a county-level measure of SES determined by the 2000 US Census, we compared cancer incidence and mortality rates for selected cancer sites by counties categorized into Low, Intermediate, and High SES. The cancers examined in this analysis included lung, colorectal, female breast, prostate, cervical, and all cancers collected by TCR combined. Consistent with other studies, most incidence and mortality rates were lowest in the High SES counties. However, in general, the highest incidence and mortality rates were found in counties categorized as Intermediate SES, but patterns differed by cancer site and by race and ethnicity. This study provides additional evidence that geographically related SES is associated with cancer incidence and mortality.
