Background: Liver cancer poses a significant health burden globally, with racial and ethnic disparities in its incidence. Among these disparities, the Black population in the United States faces a heightened risk of liver cancer due to the higher prevalence of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. This study aimed to evaluate the effectiveness of a culturally tailored educational intervention designed to enhance awareness of liver cancer prevention and screening among at-risk populations. Methods: Descriptive statistics were used to characterize participant demographics and clinical factors. Paired t-tests assessed the difference in knowledge scores before and after the intervention. Poisson regression with robust variance estimation determined the association between physicians' recommendations for testing and patients receiving blood tests. Results: The study included 137 African American participants. Prior to the intervention, the majority were aware that casual contact does not transmit HBV or HCV (79.6%) and that sharing needles for tattoos or drug injection can transmit the viruses (77.4%). The mean knowledge score increased significantly from 6.61 pre-intervention to 8.44 post-intervention (p-value&lt;0.001). Poisson regression analysis showed that African American adults were less likely to receive physician recommendations for blood tests for HBV (RR=0.95, 95%CI:0.87,1.04) and HCV (RR=0.91, 95%CI:0.83,1.00) compared to other racial/ethnic groups. Conclusions: The culturally tailored educational intervention effectively improved knowledge of HBV and HCV among African American participants, indicating the importance of culturally sensitive programs in reducing liver cancer disparities. Efforts to increase awareness of liver disease and promote testing within the healthcare system are crucial for reducing the morbidity and mortality associated with HBV and HCV infections among African Americans.
