There are conflicting reports in the literature about the possible association between left-handedness and immune disorders, including autoimmune diseases as well as allergies. In this study we compared the distribution of right- and left-handers, assessed with the Edinburgh Handedness Inventory, in a group of patients consulting an allergy clinic and a control population with a similar sex and age distribution. There was no overall association between left-handedness and allergies, although we found a tendency towards left-handedness in patients whose allergic symptoms started before puberty, suggesting that left-handers may have an increased predisposition to allergic disease that manifests itself during early life.
关于左撇子与免疫紊乱（包括自身免疫性疾病和过敏）之间可能存在的关联，文献中有相互矛盾的报道。在本研究中，我们使用爱丁堡利手量表评估了一组前往过敏诊所就诊的患者和一组性别与年龄分布相似的对照人群中右利手和左利手的分布情况。左撇子与过敏之间总体上没有关联，不过我们发现，过敏症状在青春期前开始的患者中有左撇子倾向，这表明左撇子可能在早年更易患过敏性疾病。
