The first stage was a retrospective case-control study, enrolling 535 pediatric AD patients diagnosed between 2022 and 2024 and age- and sex-matched healthy children (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009535). Conditional logistic regression models were used to analyze the associations between variables\u2014including dietary allergen sensitization (milk\/egg), air pollution index (PM2.5), indoor humidity, and skin microbiota characteristics (Staphylococcus aureus colonization rate)\u2014and AD onset. The second stage was a prospective interventional study, enrolling 66 AD children who met the full inclusion criteria between January and December 2025. Participants were divided into an intervention group (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200933, home-based care\u2009+\u2009allergen-specific dietary guidance) and a control group (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200933, conventional intervention) according to the intervention modality. Propensity score matching (PSM) was applied to balance baseline characteristics. Differences in clinical efficacy, quality of life (CD-LQI score), sleep quality (PSQI score), and disease control (ADCT score) were compared between the two groups after three months of intervention, with additional analysis of changes from baseline to follow-up.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Conditional logistic regression analysis revealed that early milk\/egg sensitization (AOR\u2009=\u20093.18, 95%CI: 2.08\u20134.78), winter indoor humidity &amp;lt;40% (AOR\u2009=\u20091.92, 95%CI: 1.30\u20132.71), PM2.5 &amp;gt;35\u2005\u03bcg\/m\n                      <jats:sup>3<\/jats:sup>\n                      (AOR\u2009=\u20092.48, 95%CI: 1.80\u20133.50), and Staphylococcus aureus colonization rate &amp;gt;50% (AOR\u2009=\u20094.08, 95%CI: 2.98\u20135.58) significantly increased the risk of AD onset (all\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05).
