Evaluation of Related Factors of Tuberculosis Indexes Changes in Hamadan Province

Tuberculosis (TB) is an infectious disease that causes acute or chronic necrotizing involvement of various body organs, especially the lungs. The relatively high annual incidence of TB and its mortality rate is a major health problem in developing countries. This study is focused on TB trends and associated factors in Hamadan. This descriptive - analytical study included all cases of TB in Hamadan province during 1384-1389. Data consist of 694 TB patients which their age, sex, place of residence and conditions were measured. Data analysis included logistic regression and trend chi-square test. Spss16 software was used for the statistical analysis. 50.4% of patients were female. Patients mean (SD) of age was s 52.2 (21.9) and 56.2% of patients were over 50 years of age. 68.6 % of patients had pulmonary Tuberculosis. There is no difference in TB incidence in different years. Place of residence (urban - rural) and gender had no effect on incidence (p>0.05), but the effect of age on the tuberculosis incidence was significant (p <0.05). education about risk factors and symptoms of TB and also more accurate case finding in this age groups is recommended with the hope to decrease the incidence of TB.
