Dr. Robert Cohn, medical director of Pulmonary Medicine at Dayton Children’s Hospital and his team studied 1,517 children who went to a pulmonary clinic at Mercy Children’s Hospital in Toledo, Ohio, for respiratory problems and left with a confirmed diagnosis of asthma. Interestingly, among these children, about 11% knew they had a peanut allergy. Many of the children in the study came back to the clinic and had a blood test to screen them for peanut allergies, and of that group, 22% tested positive. The researchers then found that more than half of the 22% of kids who came back positive did not suspect that they had any allergy or sensitivity to peanuts, suggesting it may be something that those who work with children with asthma may want to be more cognizant of. “I don’t think children with peanut allergies would be misdiagnosed with asthma. It is most likely the other way around. Children with asthma might not be recognized as having a peanut sensitivity,” says Cohn in an email to TIME. “Parents of children with asthma should understand that there may be asthma medicines that are not advised in children with peanut allergies.” Cohn says that since allergies can act as a trigger for an allergy attack, it may be useful for a child to be screened for peanut sensitivity if they have been diagnosed with asthma, especially if they have an uncontrolled cough or wheezing. The study will be presented Sunday at the ATS 2015 International Conference. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3860542/the-connection-between-peanut-allergies-and-asthma/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3860542/the-connection-between-peanut-allergies-and-asthma/"},"headline":"The Connection Between Peanut Allergies and Asthma","datePublished":"2015-05-17T15:30:52.000Z","dateModified":"2026-02-22T07:14:43.462Z","description":"New study suggests benefit from testing kids with asthma for peanut allergies","url":"https://time.com/3860542/the-connection-between-peanut-allergies-and-asthma/","keywords":["Research","Peanuts","allergies","allergy"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt2f20d230250af2ba/6987efeff887dc6828e8e7da/181634140-1-copy.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alexandra Sifferlin","jobTitle":null,"url":"https://time.com/author/alexandra-sifferlin/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt2f20d230250af2ba/6987efeff887dc6828e8e7da/181634140-1-copy.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"181634140","caption":"181634140","creditText":"Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https://time.com/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/tag/research/","name":"Research"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3860542/the-connection-between-peanut-allergies-and-asthma/","name":"The Connection Between Peanut Allergies and Asthma"}}]}] ```
