A cross-secsional study: Analysis risk factors against pulmonary TB AFB positive in Indonesia

Background: Indonesia is a third rank in TB cases worldwide. TB is a disease caused by multifactors where the environment interacts with host-related factors. So, the study was conducted to identify the multifactors and to get the main risk factor of pulmonary TB AFB positive in Indonesia.Method: A cross-sectional study, Subjects were the age group ≥15 years who were followed by the interview and had complete data. Pvalue <0,025 was considered statistically significant and included to final model by screening the factors which able to predict the prevalence of pulmonary TB.Results: The prevalence of pulmonary TB AFB positive was 1.72%. Chi square test showed statistically significant association against pulmonary TB were gender OR=1.42(1.26-1.60), Diabetes Mellitus history OR=3(2.35-3.82), Contact with active TB patients OR=3.49(2.90-4.20). Multivariate analysis showed, Active smoker, gender, age category, contact with active TB patients, and diabetes mellitus history had role against pulomonary TB AFB positive in Indonesia. The main risk factor was active smoker OR=3.71.Conclusion: Age, gender, diabetes mellitus, active smoker, and contact with active TB patients were significantly risk factors to predict pulmonary TB. Active smoker had 3.71 greater risk of having pulmonary TB compared with non pulmonary TB.
