Though overall research is limited, various studies indicate that CU is relatively common across populations with prevalence rates reportedly ranging from 5% to 20% (depending on locale, race, and age). The condition is more common in young adults, and prevalence appears to peak in adults aged 26–28 (up to 20%). The vast majority of cases are reported to be mild, and proportionally few individuals seek medical attention regarding the condition.
