W. Demarkwahnefried et al., KNOWLEDGE, BELIEFS, AND PRIOR SCREENING BEHAVIOR AMONG BLACKS AND WHITES REPORTING FOR PROSTATE-CANCER SCREENING, Urology, 46(3), 1995, pp. 346-351
Objectives. A survey to determine prostate cancer-related knowledge, b
eliefs, acid prior screening behavior was administered to men particip
ating in prostate cancer screening events at nine major sites in the s
outheast. Since prostate cancer disproportionately affects blacks, a p
rimary focus of the analysis was to determine if differences in respon
ses exist between racial groups. Methods. A 20-question, multiple-choi
ce survey to ascertain prostate cancer knowledge and beliefs, demograp
hics, and health care access information was administered at nine majo
r southeastern sites participating in Prostate Cancer Awareness screen
ing events. Potential differences between the responses of blacks and
whites were tested using the Cochran-Mantel-Haenszel test (P < 0.05),
adjusting for differences among sites. Results. Major findings of this
study on 286 black and 1218 white men are as follows: (1) only 28% of
black or white men report that their doctor ever discussed a test for
prostate cancer with them; (2) blacks were less likely to have a regu
lar doctor (P = 0.03) or ever to have had a digital rectal examination
(P < 0.001) or prostate-specific antigen testing (P = 0.005); (3) bla
cks were less likely to report knowing someone with prostate cancer (P
< 0.001) and were more ape to report their acquaintances experiencing
post-treatment impotence than whites (P = 0.03); they were less likel
y to report that ''a man with prostate cancer can lead a normal life''
(P < 0.001) or that ''men can have prostate cancer without symptoms''
(P < 0.001); (4) a substantial number of all men did not know that ra
ce and/or heredity are risk factors; and (5) ''peace of mind'' was the
leading reason why men (65% of whites and 50% of blacks) attended pro
state cancer screening events. Conclusions. There are a number of simi
larities among black and white men regarding knowledge and beliefs rel
ated to prostate cancer. Important differences, however, in access to
screening, perception of the disease and its treatment, and knowledge
of risk factors exist between racial groups and represent significant
barriers to early detection among African Americans,
