LB1485 Prevalence of alopecia areata in the United States from a large cross-sectional survey
The prevalence of alopecia areata (AA) in the United States (US) is not well known. A commonly cited self-reported period prevalence of 0.16% is sourced from the National Health and Nutrition Examination Survey (NHANES) over 40 years ago (1971-74). Other studies focused on alopecia totalis (AT; 100% scalp hair loss) and alopecia universalis (AU; complete body hair loss). We administered an online cross-sectional survey to a representative sample (n=45,016 aged ≥11years) of the US population with respect to age (11-17 years represented by parent proxy), gender, race, income, and region.
