The prevalence of concurrent hearing and vision impairment in the United States.

To the Editor 
 
The prevalence of dual sensory impairment (DSI) in hearing and vision has been estimated previously using self-reported data1, non-representative population samples2, or populations outside of the US.3 These estimates may not accurately reflect the true burden of DSI in the US. We determined the prevalence of DSI using objective assessments of hearing and vision in a nationally representative sample of US adults.
