(HealthDay News) – Prostate-specific antigen testing is more likely among affluent men, according to a study published in the October issue of The Journal of Urology.

Rhian M. Morgan, from the University of Dundee in the United Kingdom, and colleagues retrospectively analyzed anonymized data from 96,484 men (between 40 and 99 years of age) without preexisting prostate cancer who were registered with a general practitioner in Scotland. Registries were used to identify health data, including prostate-specific antigen testing, cancer incidence, and death.

The researchers found that when adjusting for age, men in the most affluent Scottish Index of Multiple Deprivation quintile had a greater chance of undergoing a prostate-specific antigen test (odds ratio, 1.48) and having prostate cancer (odds ratio, 1.48) than men in the most deprived quintile. Deprivation index quintile and prostate cancer death were not associated.

“Increased affluence was associated with a higher likelihood of a prostate-specific antigen test and a higher incidence of prostate cancer,” the authors write. “However, there were no observed differences by social class of the likelihood of a positive prostate-specific antigen test or prostate cancer-related death.”
