加州一项研究23日指出,怀孕期间居住在使用农药的农场附近,孩子罹患自闭症的风险高出2/3.这份发表在《环境健康展望期刊》(Environmental Health Perspectives)的研究,研究居住在使用农药的场所附近与后代罹患自闭症的关联性,不过未显示因果关係.自闭症是一种神经发展疾病,严重程度从轻微到重度都有,近年来比例攀升。美国当局表示,美国每68名儿童就有1人罹患自闭症。这项最新研

加州一项研究23日指出,怀孕期间居住在使用农药的农场附近,孩子罹患自闭症的风险高出2/3.这份发表在《环境健康展望期刊》(Environmental Health Perspectives)的研究,研究居住在使用农药的场所附近与后代罹患自闭症的关联性,不过未显示因果关係.自闭症是一种神经发展疾病,严重程度从轻微到重度都有,近年来比例攀升。美国当局表示,美国每68名儿童就有1人罹患自闭症。

这项最新研究,是根据美国加州使用商业用农药的资料,加上约1000户有自闭儿家庭的居住地址。

加州大学戴维斯分校(UC Davis)公共卫生科学系副主任Irva Hertz-Picciotto说:“我们找出研究参与者在怀孕期间以及大约生产时的居住地点。我们发现,这些罹患自闭症、认知或其他技能迟缓等问题的孩子,母亲怀孕期间的住所附近,使用多种类型农药的情形较为普遍。”研究人员发现,在第2或第3孕期(各为14至28周、28至42周)间使用农药,增加的自闭症风险最高。

研究作者表示,发育中的胎儿大脑可能特别容易受到农药影响。
