Peyronie’s disease (PD) is a
connective tissue disorder which can result in penile deformity. The prevalence
of diagnosed PD in the United States (US) has been estimated to be 0.5% in
adult males, but there is limited additional information comparing definitive
and probable PD cases.
We conducted a population-based survey to assess PD
prevalence using a convenience-sample of adult men participating in the
ResearchNow general population panel. Respondents were categorized according to
PD status (definitive, probable, no PD) and segmented by US geographic region,
education, and income levels.
Of the 7,711 respondents, 57 (0.7%) had
definitive PD while 850 (11.0%) had probable PD. Using univariate logistic regression
modeling, older age (18–24 vs 24+), Midwest/Northeast/West geographic region (South vs Midwest/Northeast/West), and higher income level (<25K vs 25K+) were each significantly associated with reduced
odds of having a definitive/probable PD diagnosis compared with no PD
diagnosis. When all three variables were entered in a stepwise multivariable
logistic regression, only age and region remained significant.
This study is the
first to report PD prevalence by geographic region and income, and it advocates
that the prevalence of PD in the US may be higher than previously cited. Further,
given the large discrepancy between definitive PD cases diagnosed by a
physician and probable cases not diagnosed by a physician, much more needs to
be done to raise awareness of this disease.
