Obese Teens at Risk Deaf

Loss or hearing difficulties will affect perception and social skills. Those who are hearing impaired or speech would be difficult to understand the instructions given. That would affect social relationships, performance, and poor cognitive power. Deafness usually starts with hearing loss.
A research team from Columbia University Medical Center stated, adolescents who are obese are more likely to experience hearing loss. While teens are slender, less likely.
The study said, teenagers with obesity risk of hearing loss at all frequencies. Human hearing frequency infrasound frequency that is divisible by 3, with a range of 0-20 Hz, frequency 20-20000 Hz audible and ultrasonic frequencies, with ranges> 20,000 Hz. They are also more likely to experience a loss of hearing in one ear.
This study analyzed the data of 1,500 teenage respondents from the National Health and Nutrition Examination Survey. The survey was conducted by the National Center for Health Statistics of the Centers for Disease Control and Prevention for adolescents aged 12-19 years in 2005-2006.

Interviews were conducted in the home include health history, health conditions, medication use, smoking, sosal economic, and demographic factors such as noise exposure history.
Professor Anil Lalwani study author of the Department of Otolaryngology / Head & Neck Surgery at Columbia University Medical Center stated, this study found that hearing loss is sensorineural nothing to do with work in humans.
Obesity in adolescents with sensorineural ability to hear down due to damage to the nerve fibers in the inner ear. Thus the ability of adolescents to hear, at all frequencies go down.
Average hearing loss are most numerous in the low frequencies, below 2 thousand Hz. 15 percent of obese adolescents with hearing loss, while only 8 percent of non-obese.
Teens who lose hearing in the low frequencies, they understand human speech. But they found it difficult to hear when groups or in noisy environments. Although hearing loss cases is relatively small, but the increases were two-fold. It is certainly worrying, especially the number of adolescents with obesity are increasing.
Previous research found that 80 percent of teens with hearing loss are not aware of having experienced it. Lalwani suggests, adolescents with obesity undergo hearing screening and therapy to a specific period. This is to prevent hearing loss gets worse and end up deaf.
"The results of this study should be included in the list of adverse effects of obesity. These results could motivate everyone of all ages to lose weight," says Lalwani.
