Exposure to secondhand smoke (SHS) is associated with increased risk of hearing loss among adolescents, according to a report in the July issue of Archives of Otolaryngology–Head and Neck Surgery, one of the JAMA/Archives journals.

Among U.S. children, approximately 60 percent are exposed to SHS, according to background information in the article. Studies have associated exposure to secondhand smoke prenatally or during childhood with various health conditions, from low birth weight and respiratory infections to behavioral problems and otitis media. Children exposed to SHS are more likely to develop recurrent otitis media, the authors note. “Secondhand smoke may also have the potential to have an impact on auditory development, leading to sensorineural hearing loss (SNHL),” they add.
