The latest evidence to support this hypothesis comes from a large international epidemiological study of childhood asthma that was recently published in the medical journal The Lancet . This analysis, from the International Study of Asthma and Allergies in Childhood (ISAAC), involved more than 200,000 six- and seven-year-old children from 73 centers in 31 countries.
最近在医学杂志柳叶刀发表一项针对儿童哮喘病的大型国际流行病研究所得到的最新证据也支持这一推测。这项由国际儿童过敏气喘病研究组织所进行的研究分析了31个国家里的73个中心超过20万名六七岁的儿童。这些儿童的父母或监护人都完成了一份书面问卷调查。该问卷询问了有关哮喘、鼻炎（花粉病）和湿疹的当前症状以及几个危险因素，包括在孩子一周岁以前使用扑热息痛治疗发热的情况以及在过去12个月中使用扑热息痛的频率。
