Ethnic Differences Among Black Men in Prostate Cancer Knowledge and Screening: a Mixed-Methods Study.

Black men are disproportionately affected by prostate cancer (PCa) incidence and mortality. Limited research has been reported on the ethnic differences among Black men in regard to family history, knowledge, and screening habits. Thus, this study was conducted to understand and compare knowledge levels and family history of the three main Black subgroups (African Americans, Caribbean immigrants, and African immigrants) in the USA and to assess the influence of knowledge on past screening behavior and intentionality for screening in the future for PCa. A concurrent mixed-methods design was used with participants (N = 396) recruited from different parts of the country. The grounded theory method of analysis was used for qualitative data and a logistic regression was used to explain the relationship between screening intentionality and PCa knowledge and family history. Qualitative results indicated that subjective PCa knowledge between the three subgroups was relatively similar but differed based on whether a person knew a family member or friend who had been affected by the disease. Themes focused on risk, PCa education, screening, and impact on sexuality. Quantitatively, result revealed that there are ethnic differences in knowledge across the three subgroups. Additionally, regression results revealed that family history is a stronger predictor of screening behavior and intentionality than knowledge. This study was able to unveil a deeper understanding on the role of family history and knowledge on PCa among Black subgroups.
