Asthma and rhinitis epidemiology has wide variations around the world. The aim of this review was verify the prevalence of asthma and rhinitis in South America and report differences from other regions of the world. We reviewed studies with International Study of Asthma and Allergies in Childhood (ISAAC) methodology in South America, Phases I and III. In South America the ISAAC Phase I ranked four countries among top ten in prevalence of asthma and three countries among top ten in prevalence of rhinoconjunctivitis. ISAAC Phase III showed little changes in asthma and rhinitis prevalence in South American countries. The prevalence increases of asthma and rhinitis in South American centers indicate that the burden of both is continuing to rise, but the differences in prevalence are lessening.
哮喘和鼻炎的流行病学在世界各地存在广泛差异。本综述的目的是验证南美洲哮喘和鼻炎的流行情况,并报告与世界其他地区的差异。我们回顾了在南美洲进行的、采用国际儿童哮喘和过敏研究(ISAAC)方法的研究,包括第 I 期和第 III 期。在南美洲,ISAAC 第 I 期研究结果显示,有四个国家的哮喘患病率排名前十,有三个国家的鼻结膜炎患病率排名前十。ISAAC 第 III 期研究结果显示,南美洲国家的哮喘和鼻炎患病率变化不大。南美洲各中心哮喘和鼻炎患病率的增加表明,这两种疾病的负担仍在继续上升,但患病率的差异正在缩小。
