Childhood obesity can contribute to the development of common immune-mediated skin diseases (IMSDs), such as alopecia areata, atopic dermatitis, and psoriasis, new research finds. Maintaining a healthy weight could potentially help lower the chances of developing these skin conditions. A novel study details the findings of an analysis of 2,161,900 Korean children from 2009 to 2020 to investigate the relationship between obesity or dynamic changes in body weight and the development of IMSDs.
