Smoking may up risk of hearing loss

  • There are many harmful effects of smoking
  • Smoking may also lead to a loss of hearing
  • For smokers, it can get difficult to listen to low-frequency sounds

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

“These results provide strong evidence to support that smoking is a causal factor for hearing loss and emphasise the need for tobacco control to prevent or delay the development of hearing loss,” said lead author Huanhuan Hu from the National Centre for Global Health and Medicine 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 hearing loss.

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

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

During follow-up, 3,532 individuals developed high-frequency hearing loss, and 1,575 developed low-frequency hearing loss. While the association between smoking and high-frequency hearing loss was stronger than that of low-frequency hearing loss, the risk of both high and low-frequency hearing loss increased with cigarette consumption, the researcher said.

The increased risk of hearing loss decreased within five years after quitting smoking, the researcher added. “With a large sample size, long follow-up period, and objective assessment of hearing loss, our study provides strong evidence that smoking is an independent risk factor of hearing loss,” Hu said.

Reducing Alcohol Intake Can Help In Quitting Smoking

If quitting smoking is one of your New Year’s resolutions, you might want to consider cutting back on your drinking too, a study has found.

The study found that heavy alcohol drinkers who are trying to stop smoking may find that reducing their alcohol intake can also help them quit their daily smoking habit.

In addition, heavy drinkers’ nicotine metabolite ratio — a biomarker that indicates how quickly a person’s body metabolises nicotine — reduced as they cut back on their drinking.

Slowing a person’s nicotine metabolism rate through reduced drinking could provide an edge when trying to stop smoking, which is known to be a difficult task, said lead researcher Sarah Dermody, Assistant Professor at the Oregon State University in the US.

“It takes a lot of determination to quit smoking, often several attempts,” Dermody said.

For the study, the researchers considered a small group of daily smokers to study the nicotine metabolite ratio, the medical term for severe problem drinking.

The findings, published in the journal Nicotine and Tobacco Research, showed that as the men in the study group reduced their drinking — from an average of 29 drinks per week to seven — their nicotine metabolite rate also dropped.
