Second Hand Smoke Doubles The Risk Of Hearing Loss In Teenagers

Exposure to tobacco smoke doubles the risk of hearing loss in adolescents, according to a new study.

The NYU School of Medicine, in America has published its findings as the first to link second hand some to hearing loss.

In research which involved more than 1,500 teenagers aged 12 to 19, it found that youths that were exposed to second hand smoke were more likely to have sensorineural hearing loss.

Anil Lalwani, MD, professor of professor of otolaryngology, physiology and neuroscience, and pediatrics at NYU School of Medicine, who led the research, said: “More than half of all children in the U.S. are exposed to second hand smoke, so our finding that it can lead to hearing loss in teenagers has huge public health implications.”

These figures don’t even take into account the impact on children across the rest of the world.

The study, which was published in the Archives of Otolaryngology Head & Neck Surgery, indicates the danger of second hand smoke with regard to hearing health. The teenagers were evaluated in their homes and given extensive hearing tests and blood tests at a medical centre for the chemical cotinine, a metabolite of nicotine.

Co-author Michael Weitzman, MD, professor of pediatrics and psychiatry at NYU School of Medicine, explained his distress at the discovery saying: “It’s the type of hearing loss that usually tends to occur as one gets older, or among children born with congenital deafness.”

It revealed that teenagers exposed to smoke performed worse across every sound frequency tested, especially mid-to-high frequencies important for understanding speech; and that youngsters who had greater exposure with were more likely to have one-sided or unilateral low-frequency hearing loss.

In conclusion, the researchers’ results indicated that “tobacco smoke is independently associated with an almost 2-fold increase in the risk of hearing loss among adolescents.”
