Number of siblings, birth order influence risk for allergic rhinitis in children

Children with siblings had a reduced risk for developing allergic rhinitis, particularly if they were younger and had multiple older siblings, according to study results.
“Since David Strachan, MD, PhD, in the late 1990s reported an inverse relationship between birth order and allergic rhinitis, this association has been extensively studied,” Daniil Lisik, a PhD student at the Krefting Research Centre at University of Gothenburg in Sweden, said during the presentation at the European Academy of Allergy and Clinical Immunology Hybrid Congress.
