Abstract

Abstract:

Objective: This study aims to analyze the awareness of core information on tuberculosis (TB) prevention and control among the public in Guangdong Province and to identify its influencing factors, to enhance the scientific basis and effectiveness of health promotion and health education for TB prevention and control. Methods: A multistage stratified random sampling method was employed to select 1403 permanent residents of Guangdong Province as the survey subjects. Nationally standardized questionnaire was used to conduct face-to-face interviews. A two-level logistic regression model was constructed, with individual characteristics as Level 1 units and permanent residential area as Level 2 unit, to analyze the factors associated with the awareness of core information on TB prevention and control. Results: Among 1403 permanent residents, the overall awareness rate of core information on TB prevention and control was 85.10% (5970/7015). The awareness rates for the five individual core messages and the rate for full awareness of all five messages were 76.76% (1077/1403), 90.38% (1268/1403), 92.16% (1293/1403), 87.53% (1228/1403), 78.69% (1104/1403), and 57.80% (811/1403), respectively. 75.41% (1058/1403) of all the residents had received TB health education, who had significantly higher overall awareness rate, individual message awareness rates, and full awareness rate compared with those who had not received such education (92.02% vs. 63.88% (χ²=810.22, P<0.001), 91.02% vs. 33.04% (χ²=487.04, P<0.001),95.09% vs. 75.94% (χ²=107.44,P<0.001), 96.03% vs. 80.29% (χ²=87.04, P<0.001), 92.06% vs. 73.62% (χ²=79.33, P<0.001), 85.92% vs. 56.52% (χ²=132.30, P<0.001), 71.27% vs. 16.52% (χ²=317.43, P<0.001)). Two-level multivariable logistic regression analysis revealed that females had a higher rate of full awareness of TB prevention and control core information than males (OR=1.344, 95%CI: 1.045-1.732). Individuals with middle school education and those with college or higher education had higher full awareness rates than those with primary school education or below (OR=2.106, 95%CI: 1.402-2.902; OR=1.434, 95%CI: 1.334-2.322). Residents with non-local household registration, those engaged in agricultural labor, and those who had not received TB health education had lower full awareness rates compared to their respective counterparts (OR=0.403, 95%CI: 0.237-0.683; OR=0.530, 95%CI: 0.334-0.839; OR=0.075, 95%CI: 0.054-0.103). Conclusion: The two-level model is applicable for evaluating the awareness of TB prevention and control core information among the general public in Guangdong Province. The public in Guangdong Province has a relatively high level of the awareness of core information TB prevention and control. However, further efforts are needed to enhance the public’s understanding of the TB contagiousness and curability. Targeted health education with enhanced precision should be provided to permanent residents who are male, with primary school education or below, with non-local household registration, engaged in agricultural labor, and have not received TB health education. Additionally, the coverage of health education and health promotion activities should be further expanded, with particular attention to ensuring equitable implementation in both urban and rural areas.
