Look, X!!! Yet another reason not to smoke, hearing loss!! (As if male impotence isn't enough, huh? All those guys with limp cigarettes drooping from their lips on the news were pretty funny this week.) Anyway, like many other afflictions smokers suffer in greater numbers than do nonsmokers, hearing loss also affects nonsmoking family members who live with smokers, although at a decreased level. Second hand smoke is not good for people!! Smoking linked to hearing loss NEW YORK (Reuters) -- Smoking or exposure to cigarette smoke can be linked to an increased risk of hearing loss, according to a study published in the June 3rd issue of The Journal of the American Medical Association. A study of 3,753 men and women between the ages of 48 and 92 found that smokers had a 70% greater risk of suffering from hearing loss than nonsmokers. The study, conducted by researchers at the University of Wisconsin, Madison, also suggests that nonsmokers who live with smokers are almost twice as likely to have hearing loss than those not exposed to smoke at home. Whether smoking actually contributes to hearing loss is still unclear. To confirm the link, the study's authors are now conducting a 5-year, follow-up study, in which they are tracking hearing changes among smokers and nonsmokers. "Right now we can say smokers were more likely to have hearing loss," lead researcher Dr. Karen J. Cruickshanks told Reuters Health in an interview. "We need to finish the longitudinal study before we can say whether smoking predicts who develops hearing loss." About 30% to 35% of adults ages 65 to 75 have some degree of hearing loss. While it's not clear exactly what causes this age-associated loss, it appears that genetic, environmental, and lifestyle factors all play roles. Smoking may contribute to hearing loss in a couple of different ways, said Cruickshanks, an associate professor in the department of ophthalmology and visual sciences at the University of Wisconsin. Smoking suppresses the body's ability to repair damage to blood vessels -- including blood vessels feeding structures in the ear --and also its ability to repair damage to tiny sound receptors in the ear called "hair cells," she said. Heavy smokers were somewhat more likely to suffer hearing loss than light smokers, Cruickshanks and her colleagues found. The researchers gave study participants a variety of hearing tests, and had them to fill out questionnaires regarding their smoking habits and other lifestyle patterns. After controlling for the effects of other factors that might influence hearing -- age, sex, on-the-job noise exposure, cardiovascular disease -- the researchers found hearing loss was still more common among smokers. The findings "suggest that environmental exposures may play a role in age-related hearing loss," conclude the researchers.
