背景
儿童哮喘和过敏症国际研究（ISAAC）的目的是评估生活在拉丁美洲不同地区的儿童中湿疹症状的患病率。数据来自参与ISAAC III期的研究中心。
方法
这是一项横断面问卷调查，涉及来自14个拉丁美洲国家35个中心的93，851名学龄儿童（6至7岁）和来自17个拉丁美洲国家56个中心的165，917名青少年（13至14岁）。
结果
目前弯曲湿疹在学龄儿童中的平均患病率为11.3%，范围从维多利亚城（墨西哥）的3.2%到巴兰基利亚（哥伦比亚）的25.0%。青少年的患病率从圣安德烈亚（巴西）的3.4%到巴兰基利亚的30.2%不等（平均患病率为10.6%）。学童中严重湿疹的当前症状的平均患病率为1.5%，范围从维多利亚城、托卢卡和库埃尔纳瓦卡（墨西哥）的0.3%到哈瓦那（古巴）的4.9%。青少年的平均患病率为1.4%，范围从墨西卡利谷（墨西哥）的0.1%到圣克鲁斯（玻利维亚）的4.2%。这些流行率值是ISAAC第3阶段期间观察到的最高值。总的来说，目前湿疹症状的患病率在讲西班牙语的学龄儿童和青少年中心较高。
结论
必须对环境风险因素进行评估，以确定观察到的差异的潜在原因，即使是在同一国家的中心。
BACKGROUND
The aim of the International Study of Asthma and Allergies in Childhood (ISAAC) was to evaluate the prevalence of symptoms of eczema among children living in different parts of Latin America. Data were from centers that participated in ISAAC Phase 3.
METHODS
This was a cross-sectional questionnaire survey of 93,851 schoolchildren (6 to 7 years old) from 35 centers in 14 Latin American countries and 165,917 adolescents (13 to 14 years old) from 56 centers in 17 Latin American countries.
RESULTS
The mean prevalence of current flexural eczema in schoolchildren was 11.3%, ranging from 3.2% in Ciudad Victoria (Mexico) to 25.0% in Barranquilla (Colombia). For adolescents, the prevalence varied from 3.4% in Santo André (Brazil) to 30.2% in Barranquilla (mean prevalence, 10.6%). The mean prevalence of current symptoms of severe eczema among schoolchildren was 1.5%, ranging from 0.3% in Ciudad Victoria, Toluca, and Cuernavaca (Mexico) to 4.9% in La Habana (Cuba). For adolescents, the mean prevalence was 1.4%, ranging from 0.1% in Mexicali Valley (Mexico) to 4.2% in Santa Cruz (Bolivia). These prevalence values are among the highest observed during ISAAC Phase 3. In general, the prevalence of current symptoms of eczema was higher among the Spanish-speaking centers for both schoolchildren and adolescents.
CONCLUSION
Environmental risk factors must be evaluated in order to identify potential causes for the differences observed, even in centers from the same country.
