African Americans have the highest prevalence of hidradenitis suppurativa (HS), according to the findings of a recent study published in Journal of Cutaneous Medicine and Surgery.
“While age- and sex-specific prevalence of HS is well documented in literature, few studies have explored trends in racial predilections for HS,” the researchers said. They searched Medline and EMBASE for studies on the prevalence of race in HS. Out of 184 articles that met inclusion criteria, 39 articles were included in the final analysis. The researchers scaled the population distribution based on country-specific demographic reports, which were extracted from each country’s national statistics report.
According to their findings, the average prevalence rates of HS were highest among African American populations (1.3%), intermediate among white populations (0.75%), and lowest among Hispanic/Latino populations (0.07%) and other ethnic groups (0.17%).
“Since the highest rates of HS were found among African American population, literature has highlighted the possibility of a genetic etiology in HS development,” the researchers said.
Future research is needed to examine race-specific prevalence of HS internationally in order to accurately assess the frequency and underlying etiology of HS among varying racial populations, they concluded.
