OBJECTIVE
To compare chronic respiratory symptoms, fractional exhaled nitric oxide (FENO), and lung function between Robusta and Arabica coffee workers and a control group.
METHODS
Chronic respiratory symptoms were assessed by a questionnaire (n = 138 coffee workers and n = 120 controls). The FENO was measured by NIOX MINO device (Aerocrine AB, Solna, Sweden). Lung function was examined by a portable spirometer.
RESULTS
Coffee workers had higher prevalence of chronic respiratory and asthma symptoms than controls. Robusta coffee workers were exposed to higher levels of endotoxin and had more asthma symptoms than Arabica coffee workers (38% vs. 18%). Coffee workers had reduced lung function associated with cumulative exposure to total dust and endotoxin.
CONCLUSION
Work in coffee factories is associated with small but significant lung function impairment. These changes were not associated with the level of FENO.
目的
比较罗布斯塔咖啡和阿拉比卡咖啡工人与对照组之间的慢性呼吸道症状、呼出气一氧化氮分数（FENO）和肺功能。
方法
通过问卷评估慢性呼吸道症状（n = 138 名咖啡工人和 n = 120 名对照组）。使用 NIOX MINO 设备（Aerocrine AB，瑞典索尔纳）测量 FENO。使用便携式肺活量计检查肺功能。
结果
与对照组相比，咖啡工人有更高的慢性呼吸道和哮喘症状发生率。与阿拉比卡咖啡工人相比，罗布斯塔咖啡工人接触到更高水平的内毒素，并有更多的哮喘症状（38%比 18%）。咖啡工人的肺功能与总粉尘和内毒素的累积暴露有关。
结论
在咖啡工厂工作与肺功能的微小但显著的损害有关。这些变化与 FENO 水平无关。
