| PSS007661 | For the CHILD Cohort Study, atopic dermatitis (AD) was from physician diagnosis at the one year follow-up. AD severity was defined as mild if there is a single site or no more than 2 sites, minor symptoms (little itching/rubbing), minor crusting and papules, not excoriated or oozing, not needing frequent medical attention; was defined as moderate if symptoms are neither mild nor severe or; was defined as severe if there are multiple sites, with extensive crusting or papules or excoriations or oozing or lichenification, sleep loss, needing frequent medical attention, and is a major concern to parents. In the SLSJ Cohort, atopic dermatitis was self-reported and considered as positive if past or present occurrence was reported. For children, cross validation was done using questionnaires filled by their parents. Moreover, validation in medical records of these self-reported phenotypes were done for a subset of the SLSJ Cohort (n = 217), giving 89% concordance. | — | [ ,
