The International Study of Asthma and Allergies in Childhood (ISAAC) is a standardized method that allows international and regional comparisons of asthma and allergic diseases prevalence. The objective of this study was to evaluate the prevalence of rhinitis and related symptoms among 6-7 year-old children (SC) and 13-14 year-old adolescents (AD) from 20 Brazilian cities applying the ISAAC's standardized written questionnaire (WQ).
ISAAC's WQ was applied to 23,422 SC and 58,144 AD living in different regions of Brazil: North (N), Northeast (NE), Middle West (MW), Southeast (SE), and South (S).
The prevalence of rhinoconjunctivitis in the last year ranged from 10.3% to 17.4% and from 8.9% to 28.5% among SC and AD, respectively. Considering SC the highest values were observed in SE region. In NE, the prevalence in countryside centres was higher than those along the coast. Among AD, the highest values were observed in N and S regions, mainly in Pará (Belém). The evaluation of populations probably with the same genetic background has shown higher prevalence among those living in urban centres (capital) in comparison to those in the countryside.
The prevalence of rhinitis and related symptoms were variable and predominate in Brazilian N and NE centres.
儿童哮喘与过敏国际研究（ISAAC）是一种标准化方法，可用于对哮喘和过敏性疾病患病率进行国际和区域比较。本研究的目的是应用ISAAC标准化书面问卷（WQ），评估来自巴西20个城市的6至7岁儿童（SC）和13至14岁青少年（AD）中鼻炎及相关症状的患病率。
将ISAAC的WQ应用于居住在巴西不同地区的23422名SC和58144名AD：北部（N）、东北部（NE）、中西部（MW）、东南部（SE）和南部（S）。
去年，SC和AD中鼻结膜炎的患病率分别为10.3%至17.4%和8.9%至28.5%。就SC而言，东南部地区的患病率最高。在东北部，农村中心的患病率高于沿海地区。在AD中，北部和南部地区的患病率最高，主要是在帕拉州（贝伦）。对可能具有相同遗传背景的人群进行评估发现，与农村人群相比，城市中心（首府）人群的患病率更高。
鼻炎及相关症状的患病率在巴西北部和东北部中心地区存在差异且较为普遍。
