Dual sensory impairment: Global prevalence, future projections, and its association with cognitive decline.

ABSTRACT: There is rising public health concern surrounding dual sensory impairment (DSI), or comorbid hearing and vision impairments. Its global prevalence and the magnitude of its association with cognitive decline (CD) is unclear. Three databases were searched for epidemiological studies examining DSI prevalence or its association with CD. Independent reviewers selected studies, extracted data, and evaluated bias. Random-effects meta-analyses were performed. Projections were estimated using United Nations data. The population attributable fraction of DSI-associated CD was calculated. Among 43 studies with 5,246,796 participants, clinically assessed DSI prevalence was 5.50% (95% confidence interval [CI] = 2.88%-10.26%), with regional/ethnic/age variations. DSI prevalence is projected to increase b
