Although several epidemiological studies have been conducted in Western countries, such data regarding Asian populations are scarce. In this study, we sought to investigate the demographic and clinical features of <jats:styled-content style=\"fixed-case\">HS<\/jats:styled-content> in Korea. A total of 438 patients, diagnosed with <jats:styled-content style=\"fixed-case\">HS<\/jats:styled-content> from May 2007 to April 2017, were enrolled and the electronic medical record of each patient was reviewed. Male patients were predominant with a male\u00a0:\u00a0female ratio of 2.5:1. Mean age of disease onset was 23.9\u00a0years and most patients had no family history. The most frequently affected area was the buttocks, followed by axillae and groin. Acne and diabetes mellitus were the most prevalent associated diseases and no patients with inflammatory bowel diseases were observed. In the univariable analysis, male patients had severe diseases compared with females with an odds ratio (<jats:styled-content style=\"fixed-case\">OR<\/jats:styled-content>) of 1.790. Two or more affected body regions were associated with <jats:styled-content style=\"fixed-case\">HS<\/jats:styled-content> severity with an <jats:styled-content style=\"fixed-case\">OR<\/jats:styled-content> of 1.693. While involvement of the perineum (<jats:styled-content style=\"fixed-case\">OR<\/jats:styled-content>, 4.067) and buttocks (<jats:styled-content style=\"fixed-case\">OR<\/jats:styled-content>, 1.471) tended to be associated with increased severity of the disease, the inguinal area (<jats:styled-content style=\"fixed-case\">OR<\/jats:styled-content>, 0.620) showed a tendency to be inversely associated with the severity. In multivariable analysis, identified risk factors were the involvement of the perineum (<jats:styled-content style=\"fixed-case\">OR<\/jats:styled-content>, 3.819) and buttocks (<jats:styled-content style=\"fixed-case\">OR<\/jats:styled-content>, 2.288). Smoking status and high body mass index seemed to be associated with more severe diseases. Our results will provide clinical characteristics of <jats:styled-content style=\"fixed-case\">HS<\/jats:styled-content> patients in Asia and help to broaden understanding of <jats:styled-content
