Recent advances in hearing health at the beginning and end of the life course
The World Health Organization estimates that 430 million people in the world have moderate or worse hearing loss and 1153 million have mild hearing loss. 80% live in low- and middle-income countries [1]. It is also a significant problem amongst disadvantaged groups in high-income countries. Hearing loss is the third largest cause of Years Lived with Disability (YLD) in the 2019 Global Burden of Disease Study [2].
