Association of knowledge, attitudes, and behaviors for colon cancer screening in Hispanic patients.

Purpose: The purpose of our cross-sectional study was to examine the association between sociodemographic, knowledge, attitude and behavior factors with colon cancer screening among low-income Hispanic patients from an urban family medicine clinic in San Antonio, Texas.

Methods: Using random stratified sampling, 804 patients were surveyed with 274 Hispanic patients meet the eligibility criteria for colon cancer screening (aged > or = 50 years). A 10-page self-administered questionnaire in Spanish or English completed in the clinic waiting room included self-reported colonoscopy, sociodemographic characteristics, health status, knowledge, attitudes, and behaviors toward colon cancer screening. Associations between colonoscopy and patient characteristics were assessed using logistic regression.

Results: 62% of patients reported having been tested for colonoscopy. Older Hispanics (age mean=59 + 6.1 SD) were more likely to have a colonoscopy than younger Hispanics (age mean = 56 +/- 4.8 SD) (P < .001). Bivariate analysis showed that patients who discussed colon cancer risk with their doctor (P = .001), did not smoke (P = .004), or encouraged family members or friends to be tested for colon cancer (P < .001) were more likely to be screened. Multiple variable logistic regression analysis showed that older age, having cancer, discussing the risk factors with their doctor, and encouraging family members or friends to get tested were significant predictors for colonoscopy testing in Hispanics.

Conclusions: Colonoscopy screening in a sample of low-income Hispanic patients differed by age and health experience. Intervention programs that increase colon cancer screening in Hispanics patients should concentrate on those aged < 60. Patient education for knowledge, positive attitude, and behaviors may improve colon cancer screening.
