Obesity Causes Hearing Loss?
If you like the ability to hear, then you may want to get your weight in check.
According to a new study published in the American Journal of Medicine, obesity is associated with a higher risk of hearing loss. Alternatively, higher levels of physical activity are associated with a lower risk for hearing loss. With that being said, hearing and a healthy weight go hand-in-hand.
"We often think of hearing loss as an inevitable part of the aging process," said study researcher Sharon Curhan, M.D., Sc. M., of the Channing Division of Network Medicine at Brigham and Women's Hospital. She went on to say, "These findings provide evidence that potentially modifiable risk factors, such as maintaining a healthy weight and staying physically active, may help in the prevention of hearing loss or delay its progression."
More than 68,000 women were part of the Nurses' Health Study II, and their physical activity, body mass index, waist circumference, and hearing loss were tracked from 1989 and 20 years later in 2009.
Researchers found associations amongst higher body mass index (BMI), waist circumference, and hearing loss. To be more specific, the women who experienced a BMI of 30 to 34 (signifying obesity) had a 17 percent higher risk of hearing loss. This was the result to the comparison of women who had a BMI lower than 25 (normal weight is anything from 18.5 to 24.9). Participants with a BMI of 40 or greater had a 25 percent higher risk of hearing loss.
If weight is an issue for you, researchers have fun that walking just two hours or more per week lowered hearing loss risk by 15 percent more than if people walked less than an hour a week. Exercise is substantially effective in maintaining ability to hear, especially in women who are physically active.
