<![CDATA[Background: Tuberculosis (TB) remains a major global health concern, with an estimated 10.8 million cases and 1.25 million TB-related deaths worldwide in 2023. Indonesia ranks second globally, with approximately 1.09 million cases. Workers are a high-risk population due to occupational exposure, crowding, and lifestyle factors. Respira Pulmonary Hospital is a regional referral center with a high proportion of TB cases among workers. Purpose: To analyze factors associated with TB incidence among workers seeking treatment at Respira Pulmonary Hospital, focusing on job category, knowledge level, and smoking habits. Methods: A cross-sectional study was conducted among 79 workers selected using accidental sampling. TB incidence was the dependent variable, while occupational exposure category, knowledge level, and smoking habits were independent variables. Data were collected using a structured questionnaire and analyzed using chi-square and logistic regression tests. Results: Job category was not significantly associated with TB incidence (p = 0.13), nor were smoking habits (p = 0.06). However, knowledge level was significantly associated with TB incidence (p = 0.00) and was the dominant influencing factor in multivariate analysis. Conclusion: Knowledge level was significantly associated with TB incidence among workers and was the dominant associated factor, whereas occupational exposure category and smoking habits were not significantly associated. Workplace-based TB education and health promotion should be strengthened, particularly among informal sector workers, to support TB prevention and control.]]>
