The World Bank has published disease-control priorities1 setting out cost-effective interventions for international resource mobilisation and allocation to the developing world. This list was compiled amidst the worldwide health priorities of many agencies, for attainment of the Millennium Development Goals (MDGs). 2 Many of the disease-control priorities were based on a complementary report about the global burden of disease, 3 which ranked communicable and non-communicable diseases and injuries according to their associated mortality and disability-adjusted life years (DALYs). Lopez and colleagues’3 report attempts to fairly assess the burden of diverse fatal and non-fatal diseases worldwide. The report included adult-onset hearing impairment, but excluded permanent childhood hearing impairment and all other hearing impairment of childhood-onset in the quantification of the burden of disease of this disability. This Viewpoint reviews the implications of this approach in light of the emerging trend toward early detection of childhood hearing impairment as an essential public-health service and in the context of equity, which underpins the global burden of disease initiative. 4, 5WHO defines disabling hearing impairment as having permanent unaided hearing threshold in the better ear of more than 30 dB in children aged up to 15 years, or more than 40 dB in adults at frequencies of 0· 5, 1, 2, and 4 kHz. This definition is commonly associated with sensorineural hearing impairment and tends to exclude conductive hearing loss of any severity or duration. Additionally, it overlooks unilateral permanent hearing impairment of
