Association of vision and hearing impairments with quality of life among older adults: Mediation by psychosocial factors

Vision impairment (VI) and hearing impairment (HI), alone or in combination (dual sensory impairment [DSI]), are common in older adults. We determined (i) the association of vision and hearing, and of VI only, HI only and DSI, with three psychosocial variables (social network, loneliness, depressive symptoms) and with quality of life (QoL), and (ii) whether the considered psychosocial variables mediate the association of VI only, HI only and DSI with QoL among older adults.
