Older adults and assistive devices: use, multiple-device use, and need.

Responses of older adults ( greater than 65 years) from the 1990 National Health Interview Survey and Assistive Device Supplement are analyzed to determine if selected demographic and health variables are associated with the use of assistive devices, multiple-device use, and the expressed need for such devices. Bivariate and multi-variate analyses show that, in general, poorer health is consistently associated with the use of assistive devices, multiple-device use, and expressed need. Demographic characteristics, however, vary in their relationships to assistive device use and need. Findings support the importance of considering multiple-device use and expressed need in studying assistive devices and older adults.
