Lee H, et al. - Considering that epidemiological studies on the relationship between race and alopecia areata (AA) are minimal, researchers sought to describe racial differences of AA in the United States. Using logistic regression, they assessed odds of AA and its subtypes for five ethnic/racial groups. In addition, a sex-stratified analysis and a sensitivity analysis among dermatologist-confirmed cases were conducted. Nine thousand three hundred forty AA patients and 2,064 noncases were identified. The findings suggest higher AA odds among African Americans, and lower Asian odds relative to whites. For a better understanding of the pathogenesis of the disease future studies investigating racial disparity in AA from both clinical and genetic viewpoints are needed.
