摘要

Background

Older adults with diabetes are vulnerable to coexisting nutritional deficits and chronic inflammation, yet the roles of eHealth literacy and self-management in nutrition-inflammation level (NIL) remain insufficiently understood.

Objective

This study aimed to examine the associations of eHealth literacy, self-management, and selected clinical and social characteristics with NIL among older adults with diabetes.

Methods

This study employed a cross-sectional design and enrolled older adults (≥ 60 years) with confirmed diabetes, recruited through convenience sampling at a tertiary medical center. We developed a simplified NIL score tailored for older adults with diabetes. Participants completed anonymous questionnaires, including the validated Chinese versions of the eHealth Literacy Scale (eHEALS) and the Summary of Diabetes Self-Care Activities (SDSCA). We employed SPSS 26.0 and R 4.4.3 for data analysis and graphical representation. This study adhered to STROBE guidelines for reporting.

Results

Among 246 participants (mean age 69.91 ± 7.98 years), NIL showed significant negative correlations with eHealth literacy (r = -0.243, P < 0.01) and self-management capacity (r = -0.192, P < 0.01). Forward stepwise multiple linear regression showed that higher eHealth literacy (β = -0.163, P = 0.011), better self-management capacity (β = -0.161, P = 0.013), and higher HbA1c (β = -0.216, P = 0.001) were independent factors associated with lower NIL scores, whereas rural residential environment (β = 0.200, P = 0.002) was independently associated with higher NIL scores.

Conclusion

eHealth literacy and self-management capacity were associated with nutrition–inflammation risks among older adults with diabetes, with urban–rural disparities also warranting attention. Future interventions may consider incorporating eHealth literacy and self-management support into nutrition–inflammation risk management for older adults with diabetes. These findings also suggest opportunities to embed NIL and eHealth literacy assessments into electronic health records or patient portals to support data-driven self-care in this population.
