Abstract B65: Colorectal cancer screening in nonadherent black Americans

2014 
Background: Compared with other racial groups, Black Americans have higher incidence and mortality from colorectal cancer (CRC) and lower screening rates. Theory-based tailored interventions to increase screening are more likely to be successful, especially those tailoring on stage of adoption. The purpose of our study was to examine predictors of stage of adoption for fecal occult blood testing (FOBT) and colonoscopy screening among non-adherent Black Americans. Methods: We analyzed baseline data from 817 Black primary care patients enrolled in a randomized clinical trial. Participants were categorized into precontemplation, contemplation, or preparation groups. Predictor variables examined included: demographics (age, gender, education, employment, income, health insurance, and clinical site), clinical variables (body mass index, family history of CRC, and personal history of cancer), CRC health beliefs and knowledge (perceived risk, perceived benefits, perceived barriers, self-efficacy, cancer fatalism, and knowledge), and social support (marital status, family/friend encouragement, and doctor recommendation). Hierarchical modeling was used to identify significant predictors with p value equal to or less than 0.01. Results: Participants who: were older (OR = 1.04, p = .003); male (OR = 1.70, p = .007); seen at a VA site (OR = 2.80, p Conclusion: Enhancing self-efficacy and encouragements from family and friends may be important components of interventions to promote CRC screening among Black Americans. Healthcare providers can utilize knowledge of the characteristics associated with stage of adoption to educate and motivate their primary care Black American patients to complete CRC screening tests.
