Vitiligo is a worldwide spread disease that affects around 1% of the total world population. Both sexes are affected equally and a half of patients are diagnosed under the age of 20.
Autoimmune diseases and a family history of vitiligo are considered risk factors for developing this condition. A patient that has a relative with vitiligo has an 18 fold increased risk of developing the disease and having an earlier onset of the disease.

Overview

Autoimmune diseases and a family history of vitiligo are considered risk factors for developing this condition. A patient that has a relative with vitiligo has an 18 fold increased risk of developing the disease and having an earlier onset of the disease.

Epidemiology

Prevalence

  • The prevalence of vitiligo is 1,000/100,000 (1%) of the population.
  • The prevalence varies from 100/100,000 (0.1%) up to more than 2,000/100,000 (2%) depending upon the country and age group.[1]
  • A higher prevalence has been observed in India, Romania, Uzbekistan and China.[2]

Age

  • 50% of patients with vitiligo are diagnosed before the age of 20. [3]

Gender

  • While the majority of studies state that both sexes are equally affected,[4] some studies report a higher incidence of vitiligo in young women.[5][6]
  • Females are diagnosed at a younger age than men.

Race

  • There is no difference in the prevalence among races.
  • The disease is more often noticed in dark skin patients, and may have a greater psychological impact in dark skin patients.
