一组59名工人（41名男性和18名女性）受雇于猪禁闭区进行了研究，以评估急性和慢性呼吸道症状的存在和发病率异常的排泄功能。对照组46名（31名男性和15名女性）未接触工人的慢性呼吸道症状的患病率进行了研究。对于男性和女性的猪圈养工人慢性咳嗽，呼吸困难，胸闷的投诉显着更频繁的比对照组工人。男性工人也抱怨更多的慢性痰。吸烟的男性猪圈工作者比不吸烟的男性猪圈工作者有更高的慢性咳嗽、慢性痰和慢性支气管炎的患病率。与轮班相关的急性症状在猪圈养工人中的频率很高，超过一半的工人抱怨与工作相关的咳嗽和呼吸困难。在猪圈养工人中发生了肺功能的显著急性跨班降低，FEF 25最大。所有的周一移前排泄能力测量男性坐月子的工人显着低于预测值，FVC和FEV1被发现低于女性的预测值。数据表明，在猪的圈养建筑物中的接触与急性和慢性呼吸道症状的发展以及肺功能受损有关。吸烟似乎加剧了这些变化。
A group of 59 workers (41 men and 18 women) employed in swine confinement areas was studied to assess the presence of acute and chronic respiratory symptoms and the prevalence of abnormalities in ventilatory function. A control group of 46 (31 men and 15 women) unexposed workers was studied for the prevalence of chronic respiratory symptoms. For both male and female swine confinement workers complaints of chronic cough, dyspnoea, and chest tightness were significantly more frequent than among control workers. Male workers also complained more of chronic phlegm. Male swine confinement workers who were smokers had significantly higher prevalences of chronic cough, chronic phlegm, and chronic bronchitis than male non-smoking swine confinement workers. The frequency of acute symptoms associated with the workshift was high among the swine confinement workers with more than half of the workers complaining of cough and dyspnoea associated with work. Significant acute across shift reductions in lung function occurred in swine confinement workers, being largest for FEF25. All Monday preshift ventilatory capacity measurements in male confinement workers were significantly lower than predicted values; FVC and FEV1 were found to be lower than predicted values for women. The data indicate that exposure in swine confinement buildings is associated with the development of acute and chronic respiratory symptoms and impairment of lung function. Smoking appears to aggravate these changes.
