空气污染越严重，听损风险越高？

一项台湾的研究发现：暴露于空气污染（CO和NO₂过多）中，会导致感音神经性听力损失。

该研究使用了台湾健康保险研究数据库中的数据，参与者由75767名20岁以上的成年人组成，这些参与人员此前均没有感音神经性听力损失的病史。

根据该研究数据统计，在CO水平较高的地方生活的人比在CO水平较低的地方生活的人，具有更高的感音神经性听力损失风险。

在NO₂水平较高的地方生活的人比在NO₂水平较低的地方生活的人，具有更高的感音神经性听力损失风险。

这项研究“因暴露于空气污染而导致感音神经性听力损失的风险增加”已发表在《国际环境研究与公共卫生杂志》上。

Exposure to air pollution can cause a sensorineural hearing loss, a Taiwanese study finds.

A Taiwanese study has found that exposure to carbon monoxide (CO) and nitrogen dioxide (NO2) can cause a sensorineural hearing loss. The higher the exposure, the greater the risk of a sensorineural hearing loss, according to the study.

The participants in the study were evenly exposed to low-level, mid-level and high-level carbon monoxide (CO) and nitrogen dioxide (NO2).

Higher exposure - greater risk

Participants exposed to high-level CO had a higher risk of sensorineural hearing loss compared to those exposed to low-level CO. Participants exposed to mid-level and high-level of NO2 also had a higher risk of sensorineural hearing loss than those exposed to low-level NO2.

The study used data from the National Health Insurance Research Database in Taiwan and consisted of a total of 75,767 participants aged over 20 years with no previous history of sensorineural hearing loss.

The study, “Increased Risk of Sensorineural Hearing Loss as a Result of Exposure to Air Pollution”, was published in the International Journal of Environmental Research and Public Health.
