Thorax:接触杀虫剂的5岁儿童呼吸和过敏结局

2022-03-02 MedSci原创 MedSci原创

目前的拟除虫菊酯暴露可能会影响5岁儿童的呼吸和过敏健康。代森锰锌暴露可能导致LRTI。这些结果很重要,因为拟除虫菊酯广泛用于家庭环境和农业,而代森锰锌则广泛用于农业。

关于杀虫剂对儿童呼吸和过敏结局的影响知之甚少。近日,胸部疾病领域权威杂志Thorax上发表了一篇研究文章,研究人员评估了产前和当前农药暴露与哥斯达黎加婴儿环境健康研究中儿童呼吸和过敏结局之间的关联。

在5岁儿童(n=303)中,研究人员测量了杀虫剂(毒死蜱、拟除虫菊酯)、杀菌剂(代森锰锌、嘧霉胺、噻菌灵)和2,4-D的产前和当前比重校正的尿液代谢物浓度。

研究人员从护理人员那里收集了有关呼吸道(过去12个月内曾被医生诊断为哮喘和下呼吸道感染(LRTI)、喘息和咳嗽)和过敏(鼻过敏、皮疹、湿疹)结局的信息。研究人员为高(≥75%(P75))与低(<P75)代谢物浓度与呼吸和过敏结局拟合了单独的多变量逻辑回归模型。研究人员还进行了包括代谢物浓度作为连续暴露变量的模型。

儿童的呼吸系统结局很常见(39%为咳嗽,20%为喘息,12%为哮喘,5%为LRTI)。高拟除虫菊酯代谢物浓度(∑拟除虫菊酯)与喘息(OR=2.37,95%CI为1.28至4.34)、皮疹瘙痒(OR=2.74,95%CI为1.33至5.60)、医生诊断的哮喘和LRTI相关。高乙烯硫脲(ETU)(代森锰锌的特定代谢物)与LRTI有一定的相关性(OR=2.09,95%CI为0.68至6.02)。当将∑拟除虫菊酯和ETU建模为连续变量时,研究人员获得了类似的结果。研究人员发现其他农药暴露和健康结局之间存在不一致或无效的关联。

由此可见,目前的拟除虫菊酯暴露可能会影响5岁儿童的呼吸和过敏健康。代森锰锌暴露可能导致LRTI。这些结果很重要,因为拟除虫菊酯广泛用于家庭环境和农业,而代森锰锌则广泛用于农业。
