采用欧洲社区呼吸健康调查问卷和FENO调查大学生哮喘症状流行率——症状及FENO性别差异研究
2011/11/23
摘要
背景:呼出气一氧化氮分数(FENO)被认为是嗜酸性气道炎症的一个生物标志物。哮喘患者存在FENO的增加。主观哮喘症状与气道炎症之间的关系是一个重要的课题。我们认为,女性哮喘主观症状与男性存在差异。因此,本试验通过哮喘流行率调查,研究了大学生中哮喘症状和FENO的性别差异。
方法:有关哮喘症状的信息来自于欧洲社区呼吸健康调查(ECRHS)问卷,FENO采用离线法检测。本试验共有640例参与者。
结果:基于584例(266例男性,318例女性,年龄为18~24岁)学生的数据,分析哮喘的流行率。过去1年中,584例学生中有13.2%的学生出现喘息、胸闷、气短发作或咳嗽。若将38.0 ppb作为FENO截止值用于哮喘诊断,其敏感性为86.8%,特异性为74.0%。32.7%的学生其FENO≥38.0 ppb。男性FENO水平高于女性。通过FENO水平估计的哮喘症状流行率为7.2%,男性(9.4%)流行率高于女性(5.3%)。主诉喘息的学生常发现FENO≥38.0 ppb,而主诉咳嗽的学生——特别是女性——无此现象。
结论:基于FENO和主观症状,日本18~24岁大学生哮喘症状的流行率估计在7.2%。而且与嗜酸性气道炎症相关的哮喘症状和FENO水平都存在性别差异。

Abstract
BACKGROUND:The fractional concentration of nitric oxide in exhaled air (FENO) is used as a biomarker of eosinophilic airway inflammation. FENO is increased in patients with asthma. The relationship between subjective asthma symptoms and airway inflammation is an important issue. We expected that the subjective asthma symptoms in women might be different from those in men. Therefore, we investigated the gender differences of asthma symptoms and FENO in a survey of asthma prevalence in university students.
METHODS:The information about asthma symptoms was obtained from answers to the European Community Respiratory Health Survey (ECRHS) questionnaire, and FENO was measured by an offline method in 640 students who were informed of this study and consented to participate.
RESULTS:The prevalence of asthma symptoms on the basis of data obtained from 584 students (266 men and 318 women), ranging in age from 18 to 24 years, was analyzed. Wheeze, chest tightness, an attack of shortness of breath, or an attack of cough within the last year was observed in 13.2% of 584 students. When 38.0 ppb was used as the cut-off value of FENO to make the diagnosis of asthma, the sensitivity was 86.8% and the specificity was 74.0%. FENO was [greater than or equal to]38.0 ppb in 32.7% of students. FENO was higher in men than in women. The prevalence of asthma symptoms estimated by considering FENO was 7.2%; the prevalence was greater in men (9.4%) than women (5.3%). A FENO [greater than or equal to] 38.0 ppb was common in students who reported wheeze, but not in students, especially women, who reported cough attacks.
CONCLUSIONS: The prevalence of asthma symptoms in university students age 18 to 24 years in Japan was estimated to be 7.2% on the basis of FENO levels as well as subjective symptoms. Gender differences were observed in both FENO levels and asthma symptoms reflecting the presence of eosinophilic airway inflammation. Trial registration number: UMIN000003244.
