Vitiligo diagnosis is more common in older adults and in Hispanic/ Latino and Asian American patients, according to a study published in JAMA Dermatology. Nicole Mastacouris, MD-candidate, and colleagues estimated the incidence and prevalence of diagnosed vitiligo across age, sex, and racial and ethnic subgroups in a cohort study and cross-sectional study including EHRs for children, adolescents, and adults across four US census regions. The incidence analysis included approximately 2.9 million patients with vitiligo, and the prevalence analysis included more than 1 million patients. The overall incidence rate of diagnosed vitiligo was 22.6 per 100,000 person-years (PY) after adjustment for age and sex, and prevalence was 0.16%. Patients aged 60-69 had the highest sex-adjusted overall incidence rate (22.6 per 100,000 PY), and prevalence was highest among those aged 70 and older (0.21%). The age-adjusted incidence rates among Asian American, Hispanic/ Latino, those reporting other or multiple races, Black, and White patients were 41.2, 37.3, 31.1, 29.6, and 18.7 per 100,000 PY, respectively.
