Smoking linked to increased risk of hearing loss

March 14, 2018

Smoking is associated with increased risk of hearing loss, according to a study of over 50,000 participants over 8 years in Nicotine & Tobacco Research, published by Oxford University Press.

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. 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.
