Health Literacy in Older Adults With and Without Low Vision.

Abstract

In this study, we investigated whether older adults with low vision (LV) from age-related macular degeneration (AMD) demonstrated lower functional health literacy than older adults without LV. Fifty adults with AMD were matched with adults without LV on age, gender, education, and income. We measured visual acuity, contrast sensitivity, and reading speed and administered the Test of Functional Health Literacy in Adults (TOFHLA) using two test time conditions, standard and unlimited, to measure health literacy levels. The group with LV had considerably lower TOFHLA scores for both time conditions (p < .001) and took notably longer to complete the test (p < .001). Poorer acuity correlated with lower TOFHLA scores in the group with LV. Older adults with LV may take longer to read and understand health information, which has important implications for providing health education to support self-management. Modifying components of the reading task may facilitate reading performance and understanding of health education materials.
