ABSTRACT: Tobacco use, particularly smoking, is widely recognized by the medical community as well as the general public as a major public health problem. The aim of this study was to determine tobacco smoking as a behavioral risk factor associated with pulmonary tuberculosis in adults. A case-control study design was used. The study subjects were 100 new pulmonary TB patients (cases) and age-sex matched 100 non-TB cases and healthy subjects (controls) attending Township TB Centre in Kyimyindine Township, Yangon from November 2006 to June 2007. Data were collected by face-to-face interview using questionnaires. Among the cases, proportion of non-smokers, current active smokers and ex-active smokers were 39%, 41% and 20%, respectively. Among the controls, they were 60%, 27% and 13%. It was found that current active smoking was associated with development of pulmonary TB (OR=2.15, 95% CI=1.05-4.38). Moreover, active smokers who started smoking at≤ 20 years of age (OR= 4.12, 95% CI=1.7-9.99), or had a duration of >10 yrs (OR=4.18, 95% CI=1.63-10.73), or smoked more than 10 cigarettes/day (OR=3.13, 95% CI=1.47-6.66), were at a higher risk of pulmonary TB compared to non-smokers. Therefore, an effective anti-smoking campaign is needed to have a positive repercussion on TB incidence.
