The association among eHealth literacy, depressive symptoms and health-related quality of life among older people: A cross-section study.

BACKGROUND
eHealth literacy can facilitate the uptake of benefits of health for older persons. The aim of this study was to examine the association of eHealth literacy with depression, health-related quality of life (HRQoL) among older persons.


METHODS
A survey of 6183 participants (aged 60 years and above) from 17 communities was conducted in June 2019. Participants answered questions related to basic information, eHealth literacy scale (eHEALS), geriatric depression scale and the short-form health survey (SF-36). Mediation model and a linear regression analysis were performed to explore the association between the eHEALS scores and related factors.


RESULTS
The mean score of eHEALS was 21.17 (SD = 8.25). eHEALS was significant higher in men, those with living in the city, those with high educated and stable income and those with living with children, as compared to their counterparts, respectively. Moreover, chronic diseases and depressive symptoms negatively associated with eHEALS, while actively obtaining health information and physical activity positively influenced eHEALS. Furthermore, depressive symptoms had direct and indirect effects on HRQoL, as mediated by eHealth literacy.


CONCLUSIONS
The eHEALS acts as a mediator between depressive symptoms and HRQoL. As eHealth literacy is a protector for older people, efforts to improve the older persons' eHealth literacy could help to maintain health status. Therefore, healthcare providers formulate effective programs to improve eHealth literacy for older persons, which can bring benefits for health ageing.
