Sophia George, PhD, of the University of Miami Miller School of Medicine, and colleagues investigated the mortality rate of prostate cancer in men of African ancestry living in Florida and explored the sociocultural factors that contribute to prostate cancer in the United States. The study used a quantitative, nonexperimental, descriptive study design to identify differences in the resident prostate cancer mortality rate in men of African ancestry, stratified based on single race of Black and birth origin of Haiti, Jamaica, or the United States. The investigators presented their findings at the American Association for Cancer Research (AACR) Annual Meeting 2023 (Abstract 725/12).

The researchers found there was a significant difference in prostate cancer mortality rates between men of African ancestry and men of European ancestry in the state of Florida when viewed in aggregate by ancestry (P ≤ .01). Additionally, there was a significant relationship found between African ancestry and death from prostate cancer, with a correlation coefficient of r = .866 and P value of ≤ .01. When the researchers examined the prostate cancer mortality rate in men of African ancestry in the tricounty region of South Florida in aggregate by ancestry versus disaggregate by birth origin, a significant difference was found between men of African ancestry and Haitian-born men (P =.05). However, no significant difference was found between men of African ancestry and U.S.- or Jamaican-born men. By county, the highest death rate was found in Jamaican-born men in Miami-Dade and Haitian-born men in Broward and Palm Beach. Overall, the lowest death rates in each county were found in U.S.-born men.

The study findings suggest there are clear place-based and birth-origin disparities in the South Florida region related to prostate cancer mortality rates. The study highlights the importance of considering sociocultural factors in understanding health disparities and designing interventions to address them.
