    Abstract:
    BACKGROUND: Health literacy, empowerment, and self-care activities are likely the crucial concepts affecting the quality of life and glycemic control in people with type 2 diabetes (T2D). However, evidence demonstrating the mechanisms underlying these concepts is scarce. AIMS: The aim of this study was to test the serial mediation roles of empowerment and self-care activities on the relationships between health literacy and quality of life and between health literacy and hemoglobin A1c (HbA1c) in people with T2D. METHODS: A cross-sectional study was conducted among 319 people with T2D in Guangzhou, China, from July 2019 to January 2020. Data were collected using the Health Literacy Scale, the Diabetes Empowerment Scale-Short Form, the Summary of Diabetes Self-Care Activities Measure, and the Adjusted Diabetes-Specific Quality of Life Scale. RStudio 4.2.1 was used for serial mediation analysis. RESULTS: The dimension of communicative health literacy accounted for the most total variance (β = 0.810, p < .001) in the construct of health literacy. The serial multiple mediation of empowerment and self-care activities in the associations between health literacy and quality of life (β = -.046, p = .019) and between health literacy and HbA1c (β = -.045, p = .005) were statistically significant. LINKING EVIDENCE TO ACTION: This study emphasized the vital role of communicative health literacy when improving health literacy in people with T2D. Diabetes care and education specialists could implement empowerment approaches and flexible self-care strategies to improve the quality of life and glycemic control in people with T2D. Enhancing health literacy was suggested as a favorable strategy for promoting empowerment and self-care activities in people with T2D.
