OBJECTIVE:This study examined the associations between respiratory symptoms and patterns of pulmonary dysfunction of 115 male roofing cement workers compared with 134 unexposed subjects.
METHODS:A cross-sectional study was conducted. Environmental samplings and spirometry measurements were also collected.
RESULTS:The exposed workers had higher respiratory dust exposure levels (0.65 mg/m3) compared with the unexposed groups (0.32 mg/m3). The exposed group had significantly higher prevalence than the unexposed group for shortness of breath (OR=2.19). The exposed group also had higher but insignificant prevalence of chronic cough (OR=1.34), chest tightness (OR=1.64), and wheezing (OR=1.89). The ventilatory respiratory function values (FEV1 and FVC) were slightly lower for the exposed group.
CONCLUSION:An association between higher cement dust levels and a decline in ventilatory function among roofing fiber cement workers suggests that the respiratory health of roofing cement workers should be protected through policies or work standards.

目的：本研究调查了115名男性屋面水泥工人与134名未暴露受试者的呼吸系统症状与肺功能障碍类型之间的关系。
方法：进行横断面研究。还收集了环境采样和肺活量测定法。
结果：暴露工人的呼吸粉尘暴露水平（0.65 mg / m3）高于未暴露组（0.32 mg / m3）。暴露组的呼吸困难患病率明显高于未暴露组（OR = 2.19）。暴露组的慢性咳嗽（OR = 1.34），胸闷（OR = 1.64）和喘息（OR = 1.89）的患病率也较高，但微不足道。暴露组的通气呼吸功能值（FEV1和FVC）略低。
结论：屋面纤维水泥工人中较高的水泥粉尘含量与通风功能下降之间存在关联，这表明应通过政策或工作标准保护屋面水泥工人的呼吸健康。
