Researchers sought to prospectively determine the correlations between smoking, smoking cessation, and risk of self-reported moderate or worse hearing loss among 81,505 women in the Nurses’ Health Study II (1991-2013). Validated biennial questionnaires were used to gather information on smoking and hearing status. Hearing loss was reported in 2,760 cases during 1,533,214 person-years of follow-up. Observations revealed correlation of smoking with higher risk of hearing loss; the risk tended to be higher with greater number of pack-years smoked. Per analysis, the higher risk may diminish over time after quitting.
