DIABETES has already been tied to an increased risk of kidney and cardiovascular troubles, nerve damage and vision loss, and now a Japanese study finds diabetics to be more than twice as likely as those without the disease to have hearing impairment.
In a review of past research on the issue, published in the Journal of Clinical Endocrinology and Metabolism, scientists found that younger diabetics were at even higher risk than older adults, though they could not explain why.
“Current meta-analysis suggests that the higher prevalence of hearing impairment in diabetic patients compared with nondiabetic patients was consistent regardless of age,” wrote lead researcher Chika Horikawa, at Niigata University Faculty of Medicine, and colleagues.
It’s not the first time researchers have found a link between diabetes and hearing loss. In 2008, researchers from the US National Institutes of Health (NIH) saw similar patterns in a sample of more than 11,000 people, with people with diabetes twice as likely to have hearing loss as those without.
It’s thought that high blood sugar levels brought on by diabetes may lead to hearing loss by damaging blood vessels in the ears, said Horikawa.
Horikawa and colleagues collected information from 13 previous studies examining the link between diabetes and hearing loss and published between 1977 and 2011. Together, the data covered 7,377 diabetes and 12,817 people without the condition.
Overall, Horikawa’s team found that diabetics were 2.15 times as likely as people without the disease to have hearing loss. But when the results were broken down by age, people under 60 had 2.61 times the risk while people over 60 hand 1.58 times higher risk.
Some experts caution that this kind of study does not prove that diabetes is directly responsible for the greater hearing loss rates.
“It doesn’t definitively answer the question, but it continues to raise an important point that patients might ask about,” said Steven Smith, a diabetes specialist at the Mayo Clinic in Rochester, Minnesota.
The researchers note that future studies that take more factors into account, such as age and noisy environment, are needed to clarify the link between diabetes and hearing loss.
Still, Horikawa told Reuters Health in an e-mail, people should recognize that diabetics may be at risk for hearing loss based on their results.
“Furthermore, these results propose that diabetic patients are screened for hearing impairment from (an) earlier age compared with non-diabetics,” said Horikawa, adding that hearing loss has also been linked to an increased risk of depression and dementia.
