The aim of this study was to assess chronic respiratory symptoms and lung function among female hand pickers.
A total of 374 hand pickers exposed to coffee dust and 175 female controls from water bottling factories were included. The symptoms were assessed using a standardized questionnaire. Personal total dust exposure and lung function tests were performed.
Hand pickers experienced a higher dust exposure, displayed a higher prevalence ratio for cough [prevalence ratio (PR) = 3.0, 95% confidence interval (95% CI): 1.4 to 6.2] and work-related shortness of breath (PR = 2.5, 95% CI: 1.1 to 5.6), and had a lower FEF25-75 than controls. Hand pickers without tables had a significantly higher prevalence ratio of cough with sputum (PR = 3.9, 95% CI: 1.6 to 9.5) and lower forced vital capacity, forced expiratory volume in 1 second, and mean forced expiratory flow between 25% and 75% of the FVC than hand pickers with tables.
Hand pickers show a range of adverse symptoms and lung function impairments that warrant efforts to improve working conditions.
本研究旨在评估女性拣选工的慢性呼吸道症状和肺功能。
共纳入 374 名接触咖啡尘的拣选工和 175 名来自装瓶厂的女性对照。采用标准化问卷评估症状。进行个人总粉尘暴露和肺功能测试。
拣选工的粉尘暴露更高，出现咳嗽（患病率比 [PR] = 3.0，95%置信区间 [95%CI]：1.4 至 6.2）和与工作相关的呼吸困难（PR = 2.5，95%CI：1.1 至 5.6）的患病率比值更高，且用力呼气量 25%至 75%（FEF25-75）低于对照组。没有工作台的拣选工出现有痰咳嗽的患病率比值显著更高（PR = 3.9，95%CI：1.6 至 9.5），用力肺活量、1 秒用力呼气量和用力呼气量 25%至 75%的平均用力呼气流量均低于有工作台的拣选工。
拣选工出现一系列不良症状和肺功能损伤，需要努力改善工作条件。
