Abstract
Tuberculosis (TB) is a major infectious agent leading to death in the world, accounting for 26% of preventable deaths in developing countries. About a third of the world's population is infected with tuberculosis bacilli, the majority of which live in developing countries, including Iran. The aim of this study was to evaluate the risk factors for tuberculosis. This cross-sectional study was performed on 68 TB patients. After preparing the questionnaire, they were given to the infected patients who referred to a clinic in Yazd. Then the obtained data were analyzed. No significant relationship was found between tuberculosis based on gender, occupation, education, nationality, underlying disease, smoking, diabetes, hospitalization history, age, and body mass index. According to the results of the study, it can be concluded that none of the variables: gender, occupation, education, nationality, underlying disease, smoking, hookah use, alcohol, diabetes, TB, family history, age did not increase the incidence of tuberculosis and are not considered as key risk factors for tuberculosis.
