An epidemiological study was performed with a self administered questionnaire in a representative sample of 1685 Danish farmers. The purpose of the study was to assess the prevalence of self reported asthma, wheezing during work, and symptoms of chronic bronchitis and to evaluate possible risk factors for the development of these symptoms. A response rate of 73.3% was obtained. The prevalence of asthma was 7.7% and of chronic bronchitis 23.6% in responders. The prevalence of asthma and chronic bronchitis increased from 3.6% and 17.9% in 31-50 year old farmers to 11.8% and 33.0% in 51-70 year old farmers, and from 5.5% and 17.5% in dairy farmers to 10.9% and 32.0% in pig farmers. A logistic regression analysis with correction for age and smoking habits confirmed that pig farming was a risk factor for asthma (odds ratio 2.03), chronic bronchitis (odds ratio 1.53), and wheezing during work (odds ratio 3.33).
采用自填式问卷对1685名丹麦农民的代表性样本进行了一项流行病学研究。该研究的目的是评估自我报告的哮喘、工作期间喘息以及慢性支气管炎症状的患病率，并评估这些症状发生的可能风险因素。获得了73.3%的应答率。应答者中哮喘患病率为7.7%，慢性支气管炎患病率为23.6%。哮喘和慢性支气管炎的患病率从31至50岁农民中的3.6%和17.9%增至51至70岁农民中的11.8%和33.0%，从奶农中的5.5%和17.5%增至养猪农民中的10.9%和32.0%。一项对年龄和吸烟习惯进行校正的逻辑回归分析证实，养猪是哮喘（比值比2.03）、慢性支气管炎（比值比1.53）和工作期间喘息（比值比3.33）的一个风险因素。
