BACKGROUND
Limited information is available on exposure to high molecular weight (HMW) asthmagens derived from plants and on the main occupations and tasks that result in such exposure among workers.
METHODS
Data were collected as part of the Australian Work Exposures Study-Asthma. We estimated adjusted prevalence ratios (aPR) using modified Poisson regression models to determine which factors were associated with exposure.
RESULTS
A 12.8% of 4878 workers were exposed to HMW asthmagens derived from plants. The highest prevalence of exposure was found among farmers/animal workers, education workers, and food processing workers. The main circumstances of exposure were through handling flour, freesias, or through raising livestock. Exposure was more common among female workers (aPR = 1.26, 1.10-1.43) than males, while it was lower among workers born overseas (aPR = 0.70, 0.57-0.86) than those born in Australia.
CONCLUSION
Prevention of exposure to HMW asthmagens derived from plants requires a broad strategy targeting different tasks and occupations.
背景
关于源自植物的高分子量（HMW）变应原暴露的信息有限，也缺乏导致工人暴露的主要职业和任务方面的信息。
方法
该数据是澳大利亚工作暴露研究-哮喘的一部分。我们使用修正后的泊松回归模型估计调整后的患病率比（aPR），以确定哪些因素与暴露有关。
结果
在 4878 名工人中，有 12.8%的人接触过源自植物的 HMW 变应原。在农民/动物工作者、教育工作者和食品加工工人中，暴露的比例最高。主要的暴露情况是通过处理面粉、小苍兰或饲养牲畜。与男性相比，女性工人（aPR=1.26，1.10-1.43）更容易接触，而与在澳大利亚出生的工人相比，在海外出生的工人（aPR=0.70，0.57-0.86）接触的可能性较低。
结论
预防源自植物的 HMW 变应原暴露需要针对不同任务和职业的广泛策略。
