A new study by researchers at Johns Hopkins and the National Institute on Aging suggests that hearing loss significantly increases your risk of falling.
Among older adults (age 65 or older), falls are a serious public health problem and are the leading cause of injury death in the US. According to the Center for Disease Control (CDC), nearly 20,000 older adults died from unintentional fall injuries and 2.2 million nonfatal injuries were treated in emergency departments in 2009. Direct medical costs of falls are estimated at approximately $30 billion dollars per year.
To make the connection between hearing loss and fall risk, researchers analyzed data from more than 2,000 people between the ages of 40 and 69 from 2001 to 2004, as part of the US National Health and Nutrition Examination Survey. As part of the survey, the participants had their hearing tested and also underwent vestibular testing (an examination of the balance mechanism of the inner ear), in addition to answering demographic and other health related questions.
Despite accounting for multiple factors related to fall risk (age, gender, medical condition, etc), researchers determined that even a “mild” degree of hearing loss nearly triples the risk of falling. For every additional 10 decibels of hearing loss, the risk of falling was increased by an additional 140%!
One of the most obvious reasons that people with hearing loss may have an increased fall risk is because they have less environmental awareness to things going on around them.
Frank Lin, M.D., Ph.D., one of the lead researchers in the study, suggests that another possible reason hearing loss might increase the risk of falls is due to “cognitive load”. Because the individuals with hearing loss are using more of their brain energy to help compensate for the sounds they miss, they may not be able to give enough cognitive resources to help maintain proper balance and gait and thus are more likely to experience a fall.
Researchers are hopeful that the findings of the study could help in the development of new ways to prevent falls, especially in the elderly. As more Baby Boomers join the ranks of Medicare in the coming years, fall prevention will be key in helping save lives, as well as help save billions of tax dollars in medical costs for preventable injuries.
Even the first fall can have significant consequences and in some cases can turn a spouse or child into a caregiver. If you have concerns that you or your loved one may be at risk of falling, speak with your doctor and consider the simple tips from the CDC.
