28 Aug 2025 • A global analysis of 22,743 participants found the prevalence of hidradenitis suppurativa (HS) to be 0.99%, higher than previous estimates.

Key Findings:

• Among 247 HS cases, median age was 34.5 years, and 55.6% were female, with female sex the only factor significantly linked to prevalence (β=1.02).
• Prevalence varied widely across regions (I² >75%), but no consistent associations were observed with age, BMI, smoking, GDP, or Human Development Index.

These findings position HS as a more common global health burden than previously recognized, underscoring the need for improved recognition and resource allocation.
