To study possible chronic respiratory problems of people working in swine confinement buildings, a cross-sectional epidemiological study was initiated. A cohort of swine confinement workers was matched for age, sex, and smoking history with nonconfinement swine producers. Pulmonary function studies and a survey questionnaire for chronic respiratory disease symptoms (the American Thoracic Society, Epidemiologic Standardization Project Questionnaire) were performed on both groups. Compared to controls, the confinement workers experienced significantly higher prevalence of chronic bronchitis and wheezing, (odds ratio 7 and 4, respectively). There were, however, no significant differences in baseline pulmonary functions. Based on the high prevalence of chronic respiratory disease symptoms, this study emphasizes an emerging occupational concern in agriculture to the estimated 500,000 persons working in swine confinement operations and the estimated 500,000 additional persons who work in poultry, veal, beef, or dairy confinement operations. It is important to study a representative population of these workers prospectively to determine if a progressive loss in lung function is evident.
为研究在猪舍工作的人员可能存在的慢性呼吸问题，开展了一项横断面流行病学研究。选取一组猪舍工作人员，按照年龄、性别和吸烟史与非猪舍养猪生产者进行匹配。对两组人员均进行了肺功能研究以及慢性呼吸道疾病症状调查问卷（美国胸科学会流行病学标准化项目问卷）。与对照组相比，猪舍工作人员患慢性支气管炎和喘息的患病率显著更高（优势比分别为7和4）。然而，两组人员的基线肺功能并无显著差异。基于慢性呼吸道疾病症状的高患病率，本研究强调了农业领域一个新出现的职业问题，涉及估计50万在猪舍作业的人员以及估计另外50万在禽类、小牛肉、牛肉或奶牛养殖舍作业的人员。前瞻性地研究这些工人的代表性人群，以确定肺功能是否明显出现进行性下降，这一点很重要。
