The interplay between cognitive function and digital health literacy among older adults: Implications for e-health...

Digital health literacy is increasingly vital for older adults, yet cognitive decline can impede effective use of online health resources.

This study investigated the relationship between cognitive function and e-health literacy among older adults.

A cross-sectional design was employed in six training family health centers across Izmir, Turkey. A total of 211 participants aged ≥ 65 years who reported internet use were included. Cognitive function was measured using the Mini-Mental State Examination, and digital health literacy was assessed using the Turkish version of the eHealth Literacy Scale. Data were analyzed with descriptive statistics, correlation analyses (Spearman).

The mean age was 69.58 ± 4.19 years, and 49.8 % were male. Cognitive function, as measured by the MMSE, demonstrated a significant positive correlation with eHEALS scores (r = 0.609, p < 0.001). Conversely, age was negatively correlated with eHEALS scores.

Cognitive function emerged as a key determinant of digital health literacy among older adults, even within the clinically normal MMSE range. This study is the first to highlight that subtle cognitive differences-though considered within normal limits-can significantly influence digital health engagement, our findings underscore the importance of designing user-friendly digital health interventions that accommodate age-related cognitive changes. Enhanced training and support for device usage may further mitigate barriers to effective e-health engagement in aging populations.
