Abstract

This case-control study was conducted in two tertiary level hospitals in Dhaka City to determine the association between smoking habit and relapse tuberculosis (TB).

The study population was registered adult patients who got complete treatment within 2-5 years. Relapse and non-relapse TB cases are listed serially in hospital record books. The relapse cases were selected randomly as case group and age-matched (± 2years) cured patients with the respondent of case group were included as control groups. A total of 170 respondents in each case and control groups were selected with 80% power and assuming 14% differences between cases and controls. The selected respondents who visited the respective hospitals on the scheduled day were interviewed face to face for data collection.

Mean age of the participants was 39.7±11.56 years. Significantly (χ2=20.767; p=0.000) a lower proportion of the relapse cases were found to get complete TB treatment 3 years before in comparison to that of control group. Family size more than five, education of secondary level, two earning members in the family, past smoker, smoked more than 10 cigarettes per day and exposure to second hand smoking were found to be significantly associated with higher proportion of relapse cases. Regression analysis revealed that exposure to second-hand smoking and past smokers were 2.4 and 2.0 times more likely to develop relapse TB respectively.

Tuberculosis relapse case was more likely to develop within three years of the complete TB treatment. Past smoking habit and exposure to second-hand smoking had the strongest likelihood of developing more TB relapse cases.
