By 2050, around one-in-four people will be living with some degree of hearing loss, the UN health agency warned on
Tuesday, in its first World Report on Hearing.
The World Health Organization’s (WHO) report, launched ahead of World Hearing Day 2021 on Wednesday, says that in less than 30 years, nearly 2.5 billion people globally face the threat of hearing loss – at
least 700 million of whom will require ear and hearing care as well as other rehabilitation services, unless action is
taken.
That figure would mark a significant increase from the current 430 million people worldwide who are experiencing
“disabling hearing loss”.
“Our ability to hear is precious. Untreated hearing loss can have a devastating impact on people’s ability to
communicate, to study and to earn a living”, said WHO Director-General chief Tedros Adhanom Ghebreyesus. “It can also impact on people’s mental health and their ability
to sustain relationships”.Hearing investments
The new report underlines the need to promptly step-up efforts to prevent and address hearing loss by investing and
expanding access to ear and hearing care services.
WHO has calculated that governments can expect a cost-effective return of nearly $16 for every dollar invested.
The vast majority of those with disabling hearing loss, live in low and middle income countries where policies, trained
professionals, infrastructure and basic awareness to address the issue, are commonly lacking.
“Integrating ear and hearing care interventions within national health plans and delivering these through strengthened
health systems, as part of universal health coverage, is essential to meet the needs of those at risk of or living with
hearing loss”, said Bente Mikkelsen, Director of the WHO Department of Noncommunicable Diseases.Hearing loss
In children, almost 60 per cent of hearing loss can be prevented through measures such as rubella and meningitis
immunizations, improved maternal and neonatal care, and screening for and early management of otitis media –
inflammatory diseases of the middle ear.
In adults, noise control, safe listening and surveillance of medicines that cause a toxic effect on the ear or its nerve
supply, together with thorough ear hygiene can help maintain good hearing and reduce the potential for hearing loss.Correcting the loss
Identification is the first step in addressing hearing loss and related ear diseases.
According to WHO, clinical screening at strategic points in life ensure that any loss of hearing and ear diseases can be
identified as early as possible.
Moreover, recent technological advances, including accurate and easy-to-use tools, can identify ear disease and hearing
loss at any age, and screenings can be done during the COVID-19 pandemic and in underserved areas of the world.
Once diagnosed, early intervention is key. Medical treatment can cure most ear diseases and where hearing loss is
irreversible, rehabilitation can prevent adverse consequences of hearing loss.
A range of options are available, including technology such as hearing aids and cochlear implants, which, when
accompanied by appropriate support services and rehabilitative therapy, are effective and can benefit children and
adults alike.
“To ensure that the benefit of these technological advances and solutions is equitably accessible to all, countries must
adopt an integrated people-centered approach”, Dr. Bente Mikkelsen advised.
The report also highlights that sign language and other sensory substitution, such as speech reading, are important
options for many deaf people, as are hearing assistive technology and services, including captioning and sign language
interpretation.
