960 schoolgirls of ages 8, 11 and 15 years were investigated regarding the frequency of ear piercing and the prevalence of nickel and cobalt allergy. 72% had had their ears pierced. The prevalence of nickel allergy in the whole material was 9%, among girls with pierced ears 13% and among those without pierced ears 1%. The results show that the prevalence of nickel allergy is just as high among schoolgirls as among adult women. There is a clear relationship between ear piercing and induction of nickel allergy. Prophylactic measures to reduce the prevalence of nickel allergy should be directed against this risk factor.
对960名8岁、11岁和15岁的女学生进行了关于穿耳洞频率以及镍和钴过敏患病率的调查。72%的人已经穿了耳洞。在整个样本中镍过敏的患病率为9%，在穿了耳洞的女孩中为13%，在未穿耳洞的女孩中为1%。结果表明，女学生中镍过敏的患病率与成年女性一样高。穿耳洞与镍过敏的诱发之间存在明显的关系。降低镍过敏患病率的预防措施应针对这一风险因素。
