Smoking may up risk of hearing loss

IANS  |  Tokyo 

Smokers beware. You maybe at a higher risk of suffering loss, as a new study suggests that affects the ability to hear both high and low frequency sounds.

"These results provide strong evidence to support that is a causal factor for loss and emphasise the need for tobacco control to prevent or delay the development of loss," said from the for Global and in Japan.

For the study, published in the journal Nicotine and Tobacco Research, researchers included 50,195 people, aged between 20 to 64 years and free of loss.

The researchers analysed data from annual checkups, which included audio testing performed by a and a health-related lifestyle questionnaire completed by each participant.

They examined the effects of status (current, former and never smokers), the number of cigarettes smoked per day, and the duration of cessation on the extent of loss.

The participants were followed up for a maximum of eight years.

Even after adjusting for factors including occupational noise exposure, researchers noted a 1.2 to 1.6 increased risk of loss among current smokers compared with never smokers.

During follow-up, 3,532 individuals developed high-frequency loss, and 1,575 developed low-frequency loss.

While the association between and high frequency loss was stronger than that of low frequency loss, the risk of both high and low frequency loss increased with cigarette consumption, the said.

The increased risk of loss decreased within five years after quitting smoking, the added.

"With a large sample size, long follow-up period, and objective assessment of loss, our study provides strong evidence that is an independent risk factor of loss," Hu said.
