Structural equation modeling and statistical analysis were conducted using LISREL 8.8 and Mplus 8.3 software.Results: The average score for media exposure among Chinese middle-aged and older adults was (18.55± 5.36), perceived social support was (60.68± 12.51), self-efficacy was (28.76± 5.40), and health literacy was (35.49± 6.05). Statistical results revealed that media exposure has a positive impact on the health literacy of middle-aged and older adults, with a direct effect of 0.091 (p < 0.001). Mediation analysis showed that media exposure can affect the health literacy of this population through the independent mediating effects of perceived social support (β = 0.013, p < 0.001) and self-efficacy (β = 0.029, p < 0.001), as well as through a chain mediation
