1990年代进行的几项研究表明，儿童过敏性疾病在世界范围内不断增加，但最近在一些西方国家进行的调查表明，这一趋势正在稳定，甚至可能正在逆转。然而，关于中国儿童过敏性疾病患病率现状的数据很少。本研究的目的是调查中国三个主要城市儿童哮喘、过敏性鼻炎和湿疹的患病率，了解中国儿童过敏性疾病的总体状况，并评估不同年龄儿童过敏性疾病的患病率。2008年10月至2009年5月，我们在中国三个主要城市（北京、重庆和广州）进行了一项横断面调查，以评估儿童过敏性疾病（包括哮喘、过敏性鼻炎和湿疹）的患病率，使用国际儿童哮喘和过敏研究（ISAAC）组的问卷。采用多阶段抽样方法，共对24 290名0-14岁儿童进行了访谈。为了获得3-14岁儿童的数据，我们访问了学校和幼儿园。为了了解年龄太小而不能上学或上幼儿园的儿童，我们将调查范围扩大到社区卫生服务中心。在签署知情同意书后，由儿童的父母或监护人填写每份问卷。在我们研究的24，290名儿童中，12，908名（53.14%）为男性，11，382名（46.86%）为女性; 10，372名（42.70%）来自北京，9，846名（40.53%）来自重庆，4，072名（16.77%）来自广州。调查结果显示，北京、重庆、广州三地哮喘患病率分别为3.15%、7.45%、2.09%，变应性鼻炎患病率分别为14.46%、20.42%、7.83%，湿疹患病率分别为20.64%、10.02%、7.22%。过敏性疾病的患病率随年龄而变化。在这三个城市中，哮喘在2岁以下儿童和9岁或以上儿童中相对较不常见。2岁以下儿童过敏性鼻炎的患病率也较低。湿疹的患病率随着年龄的增长而下降。中国过敏性疾病的患病率明显增加（与以前的数据相比）。进一步研究探索这种增加的确切原因是必要的。
Several studies conducted during the 1990s indicated that childhood allergic diseases were increasing worldwide, but more recent investigations in some Western countries have suggested that the trend is stabilizing or may even be reversing. However, few data are available on the current status of allergic disease prevalence in Chinese children. The aim of the present study was to investigate the prevalence rates of asthma, allergic rhinitis, and eczema in children of three major cities of China, to determine the status of allergic diseases among Chinese children generally, and to evaluate the prevalence of allergic diseases in children of different ages. We conducted a cross-sectional survey between October 2008 and May 2009 in three major cities of China (Beijing, Chongqing, and Guangzhou) to evaluate the prevalence rates of childhood allergic diseases including asthma, allergic rhinitis, and eczema, using a questionnaire of the International Study of Asthma and Allergies in Childhood (ISAAC) group. A total of 24,290 children aged 0-14 years were interviewed, using a multi-stage sampling method. To acquire data on children aged 3-14 years, we visited schools and kindergartens. To access children too young to attend school or kindergarten, we extended our survey to community health service centers. Each questionnaire was completed by a parent or guardian of a child after an informed consent form was signed. Of the 24,290 children in our study, 12,908 (53.14%) were males and 11,382 (46.86%) females; 10,372 (42.70%) were from Beijing, 9,846 (40.53%) from Chongqing, and 4,072 (16.77%) from Guangzhou. Our survey indicated that in Beijing, Chongqing, and Guangzhou, the prevalence rates of asthma were 3.15%, 7.45%, and 2.09%, respectively; the rates of allergic rhinitis were 14.46%, 20.42%, and 7.83%; and the rates of eczema were 20.64%, 10.02%, and 7.22%. The prevalence of allergic diseases varied with age. Asthma was relatively less common both in children aged under 2 years, and in those aged 9 years or more, in each of the three cities. The prevalence of allergic rhinitis was also lower in children younger than 2 years. The prevalence of eczema fell with age. A marked increase in the prevalence rates of allergic diseases in China (compared with earlier data) was evident. Further studies exploring the precise causes of this increase are warranted.
