Hypothesis
Are black men as likely as white men to report having had repeated PSA testing?
Conclusion
Self-reported repeated PSA testing differed by age and race, being higher among blacks aged 40 to 49 and lower among blacks aged 60 to 69 compared to whites.
Supporting Evidence
- 65% of men reported ever having had a PSA test.
- 41% had repeated PSA testing in the past 3 years.
- Blacks aged 40 to 49 were more likely to report repeated PSA testing than whites in the same age group.
- Blacks aged 60 to 69 were less likely to report repeated PSA testing than whites.
Takeaway
The study found that younger black men are more likely to get repeated prostate cancer tests than younger white men, but older black men are less likely to get these tests than older white men.
Methodology
The study analyzed self-reported data from a statewide survey using logistic regression to estimate the effect of race and age on repeated PSA testing.
Potential Biases
Self-reported data may lead to underestimation or overestimation of screening prevalence.
Limitations
The sample excluded people without landline telephones, which may overestimate the prevalence of prostate cancer testing.
Participant Demographics
The study included 1,721 black and white men aged 40 years or older.
