Misunderstanding of prostate cancer (CaP) among African American (AA) men of lower socioeconomic status (Lo-SES)

Abstract

6114 Background: CaP disproportionately affects AA men. The objective of this investigation was to assess understanding of the prostate and CaP among Lo-SES, predominantly AA men. Methods: We performed cross sectional, semistructured interviews of 105 men, age 40 and older, in two low-income medical clinics. CaP knowledge was assessed using a subset of questions by Mercer et al. Can J of Public Health 88(5):327, 1997. Patients were shown two male anatomic figures and asked to identify the prostate, bladder, bowels, and penis: 1) Please point to the _____ on the picture of the man. 2) What does the ____ do? Patients’ understanding of sexual, urinary, and bowel function was evaluated using semi-qualitative methods coded by two independent investigators. Demographic data were collected and literacy measured using REALM. Results: Patients’ median age was 58 and 87% self-identified their race as AA. Median annual household income was $16,000. Median reading level was 4th-6th grade. Although 87% of patients had heard of the prostate, only 24% could locate the prostate, and 3% could explain prostate function. Because many men learn about the prostate in the context of CaP screening during physical exam, 23% of patients thought the prostate was synonymous with prostate cancer, 15% of patients believed the prostate is located in the rectum and 4% confused prostate cancer with colorectal cancer. Prostate cancer knowledge was poor and the concept of a risk factor was not understood well. Only 7% could name a single risk factor for CaP including 3% who named race. Just 22% of men cited surgery or radiation therapy as treatments for CaP and 11% could name a side effect of early CaP treatment. Domain confusion was common: 43% of patients confused bowel function with urinary function, 21% confused urinary with sexual function, and 20% confused bowel with sexual function. Conclusions: Baseline understanding of CaP, anatomy, bowel, urinary, and sexual function is poor among older, lo-SES AA men. Substantial patient education is required for CaP screening and treatment efforts in this population with consideration for low literacy. [Table: see text]
