关于呼吸系统疾病流行病学研究中无反应者的数据很少。本研究的目的是探讨呼吸系统健康调查中无反应者的特征以及无反应的原因。所有9132名受试者，出生于1925-1926年、1940-1941年、1955-1956年和1970-1971年，居住在瑞典北博滕省的八个代表性地区，他们被邀请参加一项关于哮喘、慢性支气管炎和呼吸道症状的患病率研究。回应率为85%。通过电话联系横断面邮政问卷研究中未答复者的样本，并使用与邮政调查中使用的相同的问卷进行访谈。在 1397 名无反应者中，选择了 182 名受试者的分层样本进行这项研究，其中 144 名同意参加。响应率随着年龄的增加而增加。不答复的主要原因是受试者忘记邮寄问卷、缺乏兴趣或时间不够。在无反应者中，目前吸烟者和体力劳动者的比例明显更高。考虑年龄、性别、吸烟习惯、社会经济群体和居住地区的影响，单因素和多因素Logistic回归分析显示，无反应者的喘息、长期咳嗽、咳痰、呼吸困难发作、哮喘和使用哮喘药物的患病率显着高于有反应者。邮政调查中呼吸道症状和疾病的患病率略有低估。
Only few data have been published about non-responders in epidemiological studies on respiratory diseases. The aim of this study was to examine the characteristics of the non-responders and the reasons for non-response in a survey of respiratory health. All 9132 subjects, born 1925-1926, 1940-1941, 1955-1956 and 1970-1971 and living in eight representative areas in Norrbotten, Sweden, were invited to a prevalence study on asthma, chronic bronchitis and respiratory symptoms. The response rate was 85%. A sample of the non-responders from the cross-sectional postal questionnaire study was contacted by telephone and interviewed using the same questionnaire as had been used in the postal survey. Of the 1397 non-responders a stratified sample of 182 subjects were selected for this study and 144 agreed to participate. The response rate was increasing by increasing age. The main reason for non-response was that the subjects had forgotten to mail the questionnaire, lack of interest or lack of time. There were significantly higher proportions of current smokers and manual workers among the non-responders. The prevalence rates of wheezing, longstanding cough, sputum production, attacks of breathlessness, asthma and use of asthma medicines were significantly higher among the non-responders compared with the responders according both univariate and multivariate logistic regression analyses, in which the influences of age, sex, smoking habits, socioeconomic group and area of domicile were taken into account. The prevalence of respiratory symptoms and diseases was slightly underestimated in the postal survey.
