We applied an unsupervised latent class analysis (LCA) to the following 5 factors at these ages: AD, food sensitization, inhalant sensitization, poly\u2010sensitization to foods and poly\u2010sensitization to inhalants. The risks for developing asthma, allergic rhinitis and food allergy at 3 years were evaluated for each identified group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Five distinct classes were revealed by LCA: healthy (81.8%), atopic dermatitis (7.6%), inhalant sensitization (3.5%), transient sensitization (4.1%) and persistent sensitization (3.2%). Using healthy children as the baseline, children in the \u201catopic dermatitis\u201d group had the next lowest risk for all allergic outcomes at 3 years; those in the \u201cinhalant sensitization\u201d group had the highest risk for allergic rhinitis; children in the \u201ctransient sensitization\u201d group were at an increased risk for food allergy; while children in the \u201cpersistent sensitization\u201d group had the highest risk for all allergic diseases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion and Clinical Relevance<\/jats:title><jats:p>There is substantial heterogeneity among allergen\u2010sensitized children.

Children with AD who were poly\u2010sensitized to foods at an early age appear to be at greatest risk of developing other allergic diseases.<\/jats:p><\/jats:sec>","DOI":"10.1111\/cea.13063","type":"journal-article","created":{"date-parts":[[2017,11,16]],"date-time":"2017-11-16T07:16:41Z","timestamp":1510816601000},"page":"48-59","source":"Crossref","is-referenced-by-count":66,"title":["Patterns of allergic sensitization and atopic dermatitis from 1 to 3 years: Effects on allergic diseases"],"prefix":"10.1111","volume":"48","author":[{"given":"C.","family":"Dharma","sequence":"first","affiliation":[{"name":"Department of Medicine McMaster University Hamilton Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.
