BACKGROUND
Asphalt workers are exposed to bitumen fume and vapour, and to exhaust from engines and passing traffic.
AIMS
To assess the occurrence of respiratory symptoms and signs of airflow limitations in a group of asphalt workers.
METHODS
All 64 asphalt workers and a reference group of 195 outdoor construction workers from the same company participated in a cross-sectional study. Spirometric tests and a questionnaire on respiratory symptoms and smoking habits were administered. Respiratory symptoms and lung function were adjusted for age and smoking.
RESULTS
The FEV1/FVC% ratio was significantly lower in the asphalt workers than in the referents. Symptoms of eye irritation, chest tightness, shortness of breath on exertion, chest wheezing, physician diagnosed asthma, and chronic obstructive pulmonary disease (COPD) were all significantly more prevalent among the asphalt workers.
CONCLUSION
In asphalt workers there is an increased risk of respiratory symptoms, lung function decline, and COPD compared to other construction workers.
背景
沥青工人会接触沥青烟雾和蒸汽，以及发动机尾气和过往车辆的废气。
目的
评估一组沥青工人中呼吸道症状和气流受限体征的发生情况。
方法
来自同一家公司的64名沥青工人和195名户外建筑工人组成的参照组参与了一项横断面研究。进行了肺活量测定测试，并发放了一份关于呼吸道症状和吸烟习惯的问卷。对呼吸道症状和肺功能进行了年龄和吸烟因素的校正。
结果
沥青工人的第一秒用力呼气容积/用力肺活量（FEV1/FVC）百分比显著低于参照组工人。眼部刺激症状、胸闷、劳力性气短、胸部哮鸣音、医生诊断的哮喘和慢性阻塞性肺疾病（COPD）在沥青工人中都明显更为普遍。
结论
与其他建筑工人相比，沥青工人出现呼吸道症状、肺功能下降和COPD的风险增加。
