To understand the core information awareness of chronic diseases and its influencing factors among adult residents in Quanzhou City, and to provide a direction for further improving the health literacy of Quanzhou residents.

Using data from the 2023 Quanzhou Chronic Disease Social Factors Survey, the core information awareness of chronic diseases among residents was descriptively analyzed. Multivariate unconditional logistic regression was employed for analyzing influencing factors.

The core information awareness of chronic diseases among adult residents in Quanzhou 2023 was 78.5%. The awareness rate was higher in males (79.6%) than in females (77.7%) and showed a declining trend with increasing age (χ²=290.339, P<0.01). The higher education, the higher the awareness rate (χ²=481.641, P<0.01). Urban residents had a higher awareness rate (80.7%) compared to rural residents (77.3%), and residents in demonstration areas for comprehensive prevention and control of chronic diseases had a higher awareness rate (80.8%) than those in non-demonstration areas (76.0%). Multivariate unconditional logistic regression analysis showed that influencing factors included age (age 45-<65: OR: 0.805, 95% CI: 0.700-0.927; age 65 or above: OR: 0.646, 95% CI: 0.550-0.759), education level (primary school OR: 1.252, 95% CI: 1.102-1.424; junior high school OR: 1.905, 95% CI: 1.663-2.181; high school or Technical secondary school OR: 2.715, 95% CI: 2.251-3.275; College degree or above OR: 4.309, 95% CI: 3.419-5.431) and demonstration areas for comprehensive prevention and control of chronic diseases (OR: 1.120, 95% CI: 1.016-1.235). Generally, an educational attainment of primary school or above and a demonstration areas for comprehensive prevention and control of chronic diseases were the factors that promoted the awareness of core information of chronic diseases. Adult residents aged 45 and above and those in non-demonstration areas for comprehensive prevention and control of chronic diseases are risk factors for lack of awareness of core information of chronic diseases.

The core information awareness of chronic diseases among Quanzhou residents still needs improvement. Focusing on influencing factors such as age, education, and demonstration areas for comprehensive prevention and control of chronic diseases can better enhance the health literacy of residents regarding chronic diseases, effectively preventing and controlling chronic diseases.
