Relationship Between eHealth Literacy and Healthy Aging in Older Chinese People: The Mediating Effect of Health Behaviors.

Healthy aging is an important means of promoting the well-being of older individuals. However, no studies have examined the relationship between eHealth literacy and healthy aging or its mechanism. Therefore, this study aimed to examine the relationship between eHealth literacy and healthy aging and the mediating effect of health behaviors in older Chinese individuals. Cross-sectional study. We recruited 2144 older individuals from Jinan, Shandong Province, China. We used the eHealth Literacy Scale to assess eHealth literacy. Healthy aging was evaluated based on multimorbidity, functional limitations, mild cognitive impairment, depressive symptoms, and social isolation. Moreover, health behaviors were assessed using the Health-Promoting Lifestyle Profile. Logistic and linear regression models were used to analyze the relationships between eHealth literacy, healthy aging, and its components. Finally, a structural equation model was used to analyze the mediation. High eHealth literacy was associated with all healthy aging components (P <.05), including the absence of multimorbidity [odds ratio (OR), 1.014; 95% CI, 1.002–1.025], no functional limitation (OR, 1.035; 95% CI, 1.022–1.047), no mild cognitive impairment (OR, 1.042; 95% CI, 1.024–1.061), no depressive symptoms (OR, 1.049; 95% CI, 1.027–1.072), and no social isolation (OR, 1.033; 95% CI, 1.018–1.048). In the adjusted model, eHealth literacy (β = 0.174; 95% CI, 0.132–0.217) was positively correlated with healthy aging. Health behaviors had a partial mediating effect on the relationship between eHealth literacy and healthy aging. Higher eHealth literacy was associated with better healthy aging in older Chinese individuals, and health behaviors mediated this relationship. Improving eHealth literacy may be an effective intervention for achieving healthy aging. [ABSTRACT FROM AUTHOR]
