Abstract Data on pregnancy outcomes in patients with alopecia areata (AA) are limited. The aim of this study is to determine the association between maternal AA and risk of adverse birth outcomes in children, we conducted a retrospective cohort study on 45,328 children born to mothers with AA and 4,703,253 controls born to mothers without AA using the Korean National Health Insurance Claims database from 2002 to 2016. Multivariate logistic regression analyses were performed to evaluate the association between maternal AA and the birth outcomes of their children. Infants born to mothers with AA exhibited a significantly higher risk for preterm birth (odds ratio OR, 1.39; adjusted OR aOR, 1.14), low birth weight (OR, 1.36; aOR, 1.15), and cesarean section birth (OR, 1.24; aOR, 1.10)than controls. In addition, the risk of congenital malformations was also significantly higher in infants born to mothers with AA (OR, 1.19; aOR, 1.12), especially for malformations of the urinary (OR, 1.33; aOR, 1.18), circulatory (OR, 1.28; aOR, 1.11), nervous (OR, 1.26; aOR, 1.15), and musculoskeletal (OR, 1.19; aOR, 1.13) systems, than controls. Maternal AA is associated with an increased risk of adverse birth outcomes in infants.
