In the multiple regression analysis, the following independent variables were selected: 1) four inflammatory cytokine signals (IL-4, IL-6, IL-8, and IL-17); 2) birth season, which was significantly associated with the IFSAT scores; and 3) family history of atopic dermatitis, which was not significantly associated with the IFSAT scores but was speculated to influence skin problems in infants. This evidence concerns the gene IL17A and atopic eczema.
