While volatile organic compounds (VOCs) impair various organs, their influence on hearing loss (HL) has not been extensively researched. We aimed to identify the association between VOCs and HL or high-frequency hearing loss (HFHL). We extracted data on age, sex, pure tone audiometry, hypertension, occupational noise exposure, and creatinine-corrected urine VOC metabolite concentrations from the eighth Korea National Health and Nutrition Survey. Among the VOC metabolites, N-acetyl-S-(benzyl)-L-cysteine (BMA, P = 0.004), N-acetyl-S-(phenyl)-L-cysteine (SPMA, P = 0.027), and N-acetyl-S-(3,4-dihydroxybutyl)-L-cysteine (DHBMA, P < 0.001) showed associations with HL. Additionally, HFHL exhibited significant associations with BMA (P = 0.005), 3- and 4-methylhippuric acid (3, 4 MHA, P = 0.049), mandelic acid (MA, P = 0.015), SPMA (P < 0.001), N-acetyl-S-(3-hydroxypropyl)-L-cysteine (3-HPMA, P < 0.001), and DHBMA (P < 0.001). After controlling other factors, DHBMA were associated with HL (P = 0.021) and HFHL (P = 0.014) and exhibited a linear association with the mean hearing level (β = 0.054, P = 0.024) and high-frequency hearing level (β = 0.045, P = 0.037). Since 1,3-butadiene may act as an ototoxic material, early screening for workers exposed to 1,3-butadiene and reducing exposure to 1,3-butadiene in everyday life may be helpful to prevent further HL.
虽然挥发性有机化合物 (VOCs) 会损害各种器官,但它们对听力损失 (HL) 的影响尚未得到广泛研究。我们旨在确定 VOC 与 HL 或高频听力损失 (HFHL) 之间的关联。我们从第八次韩国国家健康和营养调查中提取了年龄、性别、纯音测听、高血压、职业噪声暴露以及肌酐校正尿液 VOC 代谢物浓度的数据。在 VOC 代谢物中,N-乙酰-S-(苄基)-L-半胱氨酸 (BMA,P=0.004)、N-乙酰-S-(苯基)-L-半胱氨酸 (SPMA,P=0.027) 和 N-乙酰-S-(3,4-二羟基丁基)-L-半胱氨酸 (DHBMA,P<0.001) 与 HL 相关。此外,HFHL 与 BMA (P=0.005)、3- 和 4-甲基马尿酸 (3,4 MHA,P=0.049)、扁桃酸 (MA,P=0.015)、SPMA (P<0.001)、N-乙酰-S-(3-羟基丙基)-L-半胱氨酸 (3-HPMA,P<0.001) 和 DHBMA (P<0.001) 呈显著相关。在控制其他因素后,DHBMA 与 HL (P=0.021) 和 HFHL (P=0.014) 相关,并与平均听力水平 (β=0.054,P=0.024) 和高频听力水平 (β=0.045,P=0.037) 呈线性相关。由于 1,3-丁二烯可能是一种耳毒性物质,因此对接触 1,3-丁二烯的工人进行早期筛查,并减少日常生活中接触 1,3-丁二烯,可能有助于预防进一步的 HL。
