The frequency of risk factors for pulmonary tuberculosis in tuberculosis patients in Babol, Northern Iran, during 2008-2015

In the current study, we investigated the risk factors for tuberculosis in patients admitted to the Ayatollah Rouhani Hospital in Babol, north of Iran. This cross-sectional study was conducted on 207 patients with proven tuberculosis during the years 2008-2015. Demographic data such as age and sex, smoking, history of underlying illness, illness symptoms, and laboratory results were collected and analyzed at a significant level of less than 0.05. From 207 patients, 136 were male (65.7%), 71 were female (34.3%), and 76 of them (37.3%) were smokers. It is notable that most patients (29.5%) were over the age of 71. The relation between age profile and being tuberculosis has been studied, but the co-relation was found to be not significant. The most common complaint has been coughing (60.9%).
