国际儿童哮喘和过敏研究（ISAAC）第一阶段报告了儿童哮喘、鼻炎和湿疹症状的患病率。在来自40个国家的99个中心，共有不到317，000名13-14岁的儿童完成了一份视频问卷，显示了哮喘的症状和体征。将第一个视频序列与ISAAC询问当前喘息的书面问题进行比较，以探索各中心、地区和语言组之间的一致性差异以及每份问卷对喘息患病率的贡献。总体一致性比例较高，平均为0.89，但不平衡，阴性一致性较好，阳性一致性较差。使用Cohen的kappa系数进行的机会校正一致性通常较低，只有20个中心的kappa >0.4。每个调查问卷对喘息患病率的贡献也因中心而异，并表明13-14岁的青少年对喘息的书面问题理解和解释能力较差，喘息及其视听演示的国际比较表明，青少年对喘息的书面问题的解释与视听演示不同，这种解释显示了中心之间的差异。为了更好地预测哮喘，需要进一步研究这种关系以及对症状的书面和视听表现的解释。
Phase One of the International Study of Asthma and Allergies in Childhood (ISAAC) has reported the prevalence of asthma, rhinitis and eczema symptoms in children. In 99 centres from 40 countries, a total of just under 317,000 13-14-yr-old children also completed a video questionnaire, showing the symptoms and signs of asthma. This first video sequence has been compared to the ISAAC written question asking about current wheezing to explore variations in agreement and the contribution of each questionnaire to wheezing prevalence between centres, by region and language groups.In general, responses to the video questionnaire gave a lower prevalence than the written questionnaire and responses were closely correlated. The overall proportion of agreement was high, mean 0.89, but unbalanced, with good negative agreement but poor positive agreement. Chance corrected agreement using Cohen's kappa coefficient, was generally low, with only 20 centres with kappa >0.4. The contribution of each questionnaire to wheezing prevalence also varied between centres and suggests that written questions about wheezing are variably understood and interpreted by 13-14 yr olds.International comparisons of wheezing and its audiovisual presentation suggest that adolescents interpret a written question about wheezing differently from its audiovisual presentation and that this interpretation shows variation between centres. This relationship and the interpretation of both written and audiovisual presentation of symptoms requires further study in order to better predict asthma.
