一项汇总分析研究发现，在工作中接触农药的人群患肌萎缩侧索硬化症（ALS）的风险显著上升[1]。这项研究综合了来自美国、加拿大、法国、意大利和澳大利亚的8项独立研究数据，共涉及1,734例ALS病例，发现职业农药暴露与61%至71%的风险增加相关联[1]。其中除草剂暴露的关联性最强，与71%的风险增加有关[1]。
研究结果表明农药接触可能是ALS的一个风险因素，但专家提醒需要谨慎解读这些发现[1]。多项研究依赖患者自我报告的暴露情况，这可能导致回忆偏差，加之不同研究的方法差异，也会影响结论的可靠性[1]。
澳大利亚每100,000人中约8人患ALS[1]，患者平均生存期为确诊后2至3年[1]。超过90%的ALS患者属于散发型，没有已知的家族史或特定基因原因[1]。
A comprehensive analysis of eight independent studies has identified a significant link between occupational pesticide exposure and amyotrophic lateral sclerosis (ALS), commonly known as motor neurone disease.[1] The meta-analysis, which consolidated data from 1,734 ALS cases across research conducted in the United States, Canada, France, Italy, and Australia, found that individuals exposed to pesticides in the workplace face a 61 to 71 percent increased risk of developing the condition.[1] Herbicide exposure specifically was associated with a 71 percent elevated risk.[1]
The findings suggest that pesticide exposure may constitute a previously underrecognized occupational risk factor for ALS, a neurodegenerative disease with severe consequences.[1] In Australia alone, approximately 8 people per 100,000 experience the disease, with diagnosed patients typically surviving 2 to 3 years following diagnosis.[1] Over 90 percent of ALS cases are sporadic in nature, occurring without known family history or genetic causes.[1] However, researchers urge caution in interpreting these results, noting that methodological variations across studies and reliance on self-reported exposure history in many investigations introduce potential recall bias that may affect the reliability of the estimates.[1]
