Islamabad Aug. 23(online) — More than 740 million adults worldwide have had at least one symptom of tinnitus, and about 120 million are severely affected, according to a new report.<\/p>\n
Tinnitus indicates the perception of a ringing, buzzing, whistling, rustling, or hissing noise in the ears or head when no corresponding external sounds are present. In its most severe form, which is associated with hearing loss, tinnitus can affect a patient’s mental, emotional, and social health.<\/p>\n
Researchers have lacked a clear indicator of how widespread the disorder is globally, as well as of who suffers the most serious symptoms.<\/p>\n
“Our estimates indicate that, worldwide, 1 in 7 adults reported experiencing tinnitus,” says Carlotta MicaelaJarach, study author and an epidemiologist at the Mario Negri Pharmacological Research Institute in Milan, Italy.<\/p>\n
“Severe tinnitus has been found in about 2% of the population,” she says.
\nThe study was published in JAMA Neurology on August 8.
\nAssociation With Age.<\/p>\n
Jarach and colleagues from several European universities conducted a wide-ranging review of past international research to estimate the global prevalence and incidence of tinnitus, severe tinnitus, chronic tinnitus, and diagnosed tinnitus.<\/p>\n
They looked at research published in 767 publications, then focused on prevalence and incidence estimates from 95 of the studies.<\/p>\n
Pooling the data from all those studies, the research team calculated that the prevalence estimate of any tinnitus among adults was 14.4%; The prevalence did not differ significantly by sex; it was about 14.1% among men and 13.1% among women.<\/p>\n
But the prevalence differed by age, with an estimate of about 13.6% among children and teensAmong adults, the prevalence increased with age, starting around 9.7% for ages 18 to 44 years and rising to 13.7% among ages 45 to 64 years, and 23.6% among ages 65 years and older.<\/p>\n
The prevalence in adults appeared to differ significantly by continent, ranging from 5.2% in Africa to about 14% in Europe and North America and 21.9% in South America.<\/p>\n","protected":false},"excerpt":{"rendered":"
