In a 2015 study that investigated the association between hearing loss and mortality, researchers from Johns Hopkins University found that adults 70 years and older with moderate or severe hearing loss had a 54% increased risk of mortality compared to peers without hearing loss.
Researchers studied data from two National Health and Nutrition Examination Surveys — the 2005 through 2006 one, and 2009 through 2010 — examining 1,666 adults 70+ who had undergone audiometric testing. Those with hearing loss tended to have shorter lifespans.
While the study’s leads were clear to note the results didn’t prove that hearing loss, alone, shortens lives, they did point out the many negative effects of hearing loss (read some here), suggesting a combination may contribute to the earlier deaths.
