To analyze the status and influencing factors of latent tuberculosis infection (LTBI) screened by the recombinant mycobacterium tuberculosis fusion protein (EC) test in Henan Province, and to understand the willingness of LTBI individuals to accept preventive treatment, with the aim of providing data support for improving tuberculosis (TB) control strategies in Henan Province.
In 2023, the EC test was used to screen for LTBI and conduct preventive treatment among high-risk groups for TB (including school teachers and students, healthcare workers, close contacts, and HIV/AIDS patients) in counties participating in the Henan Province TB Care Action public welfare project. Excel 2019 and SPSS 21.0 software were used to analyze the data. Binary logistic regression model was used to analyze the influencing factors of latent tuberculosis infection.
A total of 4 818 subjects were included in the study, excluding those who had not been screened for latent infection due to other reasons such as screening contraindications. The positive rate of EC test was 4.42% (213/4 818). Four patients with active pulmonary tuberculosis were found, and the detection rate was 83.02/100 000 (4/4 818). 204 people met the criteria for preventive treatment, 86 people received preventive treatment, the acceptance rate was 42.16% (86/204), the completion rate was 89.53%(77/86), among which the main reason for refusal was that they thought they would not get sick (77.97% (92/118)). Binary logistic regression model analysis results showed that with students as the control group, medical staff (OR=9.762，95% CI：3.441-27.697), close contact staff (OR=6.853, 95% CI：3.074-15.277), HIV/AIDS (OR=4.387, 95% CI：1.582-12.165) were risk factors for TB infection.
Healthcare workers, close contacts, and HIV/AIDS patients are the focus of LTBI screening. Additionally, enhancing the awareness of preventive treatment among individuals with latent infections is crucial to improving the acceptance rate of preventive treatment and advancing TB control efforts in Henan Province.
