INTRODUCTION: Hispanics in New Mexico are diagnosed with more later-stage colorectal cancer (CRC) than non-Hispanic Whites (NHW). Our study evaluated the interaction of race/ethnicity and risk factors for later-stage III and IV CRC among patients in New Mexico.
METHOD: CRC patients ages 30 to 75 years ( n = 163, 46% Hispanic) completed a survey on key explanatory clinical, lifestyle, preventive health, and demographic variables for CRC risk. Adjusted logistic regression models examined whether these variables differentially contributed to later-stage CRC among NHW versus Hispanics.
RESULTS: Compared with NHW, Hispanics had a higher prevalence of later-stage CRC ( p = .007), diabetes ( p = .006), high alcohol consumption ( p = .002), low education ( p = .003), and CRC diagnosis due to symptoms ( p = .06). Compared with NHW, Hispanics reporting high alcohol consumption (odds ratio [OR] = 7.59; 95% confidence interval [CI] = 1.31-43.92), lower education (OR = 3.5; 95% CI = 1.28-9.65), being nondiabetic (OR = 3.23; 95% CI = 1.46-7.15), or ever smokers (OR = 2.4; 95% CI = 1.03-5.89) were at higher risk for late-stage CRC. Adjusting for CRC screening did not change the direction or intensity of the odds ratios.
CONCLUSION: The ethnicity-risk factor interactions, identified for late-stage CRC, highlight significant factors for targeted intervention strategies aimed at reducing the burden of later-stage CRC among Hispanics in New Mexico with broad applicability to other Hispanic populations.
