Background: The 2023 AAAAI/ACAAI/JTFPP guidelines advise against elimination diets for treating atopic dermatitis (AD); however, many parents continue to use them, exposing their children to risks such as malnutrition and potential anaphylaxis upon reintroduction. This study surveyed parents of children with AD to explore their perceptions of the relationship between diet and their child’s condition, while also examining how these views may vary across race, ethnicity, income, and education levels—factors critical to informing future educational strategies for this vulnerable population. Methods: This IRB-approved cross-sectional survey was conducted at a single academic center from April to September 2024. Parents of children with AD diagnosis (n=295) completed the survey in the ED, allergy, dermatology, and general pediatrics clinics. Results: 47% (114/241) of participants reported that specific foods worsened their child’s AD, with the most common triggers being milk (34%); tree-nuts/seeds/peanuts (16%); and egg (14%). Among those who identified food triggers, 25% removed the suspected allergens from their child’s diet, though 42% of those parents observed no improvement in AD. Additionally, 52% of parents reintroduced the suspected allergens without significant change in AD severity (p <0.001). Black respondents were more likely than White respondents to fully eliminate the identified allergens (p = 0.006). Conclusion: In this survey, parental perception of AD and its dietary links significantly influenced their children’s diets. Despite elimination diets, only one-third of respondents saw mild improvement in AD presentation. Larger studies are needed to confirm diet’s role in AD.
