The relationship between sensory loss and health literacy in older adults: A systematic review

Objectives: As sensory loss may impact the ability to receive and apply health information, a relationship between sensory loss and health literacy may exist. The purpose of this systematic review was to explore the relationship between hearing, vision and dual sensory loss and health literacy in older adults.

Methods: Studies examining the relationship between sensory loss and health literacy in older adult populations using a validated health literacy instrument were included. The search was conducted in the CINAHL, PubMed, Scopus, AgeLine and REHABdata databases in May-June 2021.

Results: Nine studies were included. Findings revealed a positive association between hearing and vision loss and low health literacy.

Discussion: This review highlights a relationship between hearing and vision loss and low health literacy. The small number of studies and overall heterogeneity of study methods limits strength of this evidence. Individuals with sensory loss may benefit from additional clinician support in receiving and applying health information.
