ISLAMABAD: A new study suggests that smoking affects the ability to hear both high and low-frequency sounds.
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.
“These results provide strong evidence to support that smoking is a causal factor for hearing loss and emphasize 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.
The researchers analyzed 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.
