  "abstract": "Introduction: This study examined whether community health information exposure was associated with chronic disease preventive behavior among middle-aged and older adults, with particular attention to the chained mediating roles of risk perception and preventive self-efficacy and the moderating role of health literacy.\n\nMethods: An exploratory sequential mixed-methods design was adopted. In the qualitative phase, semi-structured interviews were conducted with 27 middle-aged and older community residents from six community health service centers in Sichuan and Chongqing, China. In the quantitative phase, 704 valid questionnaires were collected through site-based convenience sampling from eight community health service centers, three senior activity stations, and family-doctor-contracted populations. Confirmatory factor analysis, structural equation modeling, and bootstrap procedures were used to test the proposed model.\n\nResults and discussion: Community health information exposure was positively associated with chronic disease preventive behavior (β = 0.143, p < 0.01) and risk perception (β = 0.417, p < 0.001). Risk perception was further positively associated with preventive self-efficacy (β = 0.358, p < 0.001) and chronic disease preventive behavior (β = 0.119, p < 0.01). Preventive self-efficacy showed the strongest positive association with preventive behavior (β = 0.528, p < 0.001). Risk perception and preventive self-efficacy each showed significant indirect effects, and together formed a significant chained mediation path (indirect effect = 0.079, 95% CI [0.051, 0.115]). Health literacy significantly moderated the path from community health information exposure to risk perception (β = 0.154, p < 0.001) and was associated with a stronger chained indirect effect. Community health information exposure may contribute to chronic disease prevention partly through greater risk awareness and stronger preventive self-efficacy. Improving health literacy may help strengthen the translation of community health information into sustained preventive action, although longitudinal and intervention studies are still needed.",
