Purpose: Visual impairment and, to a lesser extent, hearing impairment are independent predictors of reduced survival in selected studies of community-residing adults. To date, the association of severity of concurrent impairment and mortality has not been examined. Method: The National Health Interview Survey is a continuous, multistage, area probability survey of the U.S. civilian noninstitutionalized population. Mortality linkage with the National Death Index of 116,796 adult participants from 1986 to 1994 with complete impairment data was performed through 1997. Results: Findings indicate that moderate to severe concurrent hearing and visual impairment in women is associated with significantly increased risk of mortality. More modest mortality associations are evident for men and for adults with less severe impairments, irrespective of gender. Discussion: Prevention of severe visual and hearing impairment should be a national public health priority, especially given the aging of the U.S. population.

Key Words: hearing impairment • visual impairment • comorbidity • mortality
