One out of six, or 29 million adults, have some trouble discerning speech, more than previous estimates, [a team at Johns Hopkins University] reported in the Archives of Internal Medicine.
"The prevalence of hearing loss in the United States is predicted to rise significantly because of an aging population and the growing use of personal listening devices. Indeed, there is concern that we may be facing an epidemic of hearing impairment," Dr. Yuri Agrawal of Johns Hopkins wrote.
It is common for people to ignore or disavow hearing loss, the researchers said, leading to difficulty communicating that can result in productivity problems at work, depression, and less access to health care that ultimately raises the risk of sickness and death.
The study said:
In 2003-2004, 16.1 percent of U.S. adults (29 million Americans) had speech-frequency hearing loss. In the youngest age group (20-29 years), 8.5 percent exhibited hearing loss, and the prevalence seems to be growing among this age group. Odds of hearing loss were 5.5-fold higher in men vs. women and 70 percent lower in black subjects vs white subjects. Increases in hearing loss prevalence occurred earlier among participants with smoking, noise exposure, and cardiovascular risks.
Hearing loss is more prevalent among U.S. adults than previously reported. The prevalence of U.S. hearing loss differs across racial/ethnic groups, and our data demonstrate associations with risk factors identified in prior smaller-cohort studies. Our findings also suggest that hearing loss prevention (through modifiable risk factor reduction) and screening should begin in young adulthood.
