Abstract

Atopic dermatitis is one of the most common chronic skin diseases. Infantile atopic dermatitis may be caused, in particular, by exposure to indoor environmental factors during gestation and infancy; however, the underlying mechanism is unknown. A total of 2,609 healthy newborns who were enrolled in the COCOA study (COCOA) from 2008 to 2015 were surveyed for indoor environmental exposure to fungi during gestation and then diagnosed postnatally for atopic dermatitis. Fungal microorganisms were analyzed in house dust samples collected during gestation and their relationship was investigated. A total of 2,609 respondents were surveyed (52.8% male and 47.2% female) Children, 1, 2, and 3 years old diagnosed with atopic dermatitis comprised 15.2%, 15.7%, and 14.1% of the respondents, respectively. The prevalence of exposure to mold during gestation was 1.46 (95% CI, 1.05-2.04) and 1.52 (95% CI, 0.95-2.43), in the first and third years after birth, respectively. One-year-old children with atopic dermatitis and no fungal markers detected in the bathroom environment during gestation accounted for less than 5% (aOR, 1.51; 95% CI, 0.96-2.38). Exposure to indoor fungi during gestation and infancy is associated with the development of atopic dermatitis in children. Future research will be necessary to establish the underlying mechanisms.
