Hearing problems could affect one in four people by 2050, WHO warns, and urges more spending on prevention
- One in five people worldwide has hearing problems, causing economic losses of US$1 trillion a year, and a report says their number may rise to one in four
- Many of the problems that cause deafness – such as infections, diseases, birth defects and noise exposure – could be prevented, the WHO report says
One in four of the world’s population will suffer from hearing problems by 2050, the World Health Organisation (WHO) said this week, and called for extra investment in prevention and treatment.
The first global report on hearing said the causes of many of the problems – such as infections, diseases, birth defects, noise exposure and lifestyle choices – could be prevented.
The report proposed a package of measures, which it calculated would cost US$1.33 per person per year. Against that, it set the figure of nearly US$1 trillion lost every year because the issue was not being properly addressed.
“Failure to act will be costly in terms of the health and well-being of those affected, and the financial losses arising from their exclusion from communication, education and employment,” said the report.
One in five people worldwide have hearing problems currently, it said. But the report warned: “The number of people with hearing loss may increase more than 1.5-fold during the next three decades” to 2.5 billion people – up from 1.6 billion in 2019.
Of the 2.5 billion people affected in 2050, 700 million would have a serious enough condition to require some kind of treatment, the report said – up from 430 million in 2019.
