Comparative study of the profiles of tribal and non-tribal tuberculosis patients in a tuberculosis unit of West Bengal, India.
BACKGROUND
Worldwide, the burden of tuberculosis (TB) is high in tribal populations.


METHODS
Department of Community Medicine, Burdwan Medical College, Burdwan, India.


OBJECTIVE
To compare the profile of TB patients among tribals and non-tribals in the Bhatar Tuberculosis Unit,  Burdwan, India.


METHODS
A record-based cross-sectional study was conducted among 599 TB cases in 2009.


RESULTS
Respectively 34.7% and 65.3% of the cases were tribals and non-tribals. Among tribal patients, 92.3% had pulmonary TB vs. 82.1% among non-tribals. The proportion of Category  I cases (77.4%) was higher among tribals than among non-tribals (60.8%), while the proportion of Category II and III cases was higher among non-tribals. Among new sputum-positive Category I cases, the sputum conversion rate at the end of the intensive phase was respectively 92.4% and 87.7%  in tribals and non-tribals. Unfavourable treatment outcome was higher in males and among failure, relapse, treatment after default and transferred out cases.


CONCLUSIONS
Differences were noted in type/category of cases, sputum conversion as well as in outcome between tribal and non-tribal  TB patients. Although ethnicity by itself was not significantly associated with outcome, factors related to ethnicity might have contributed to these differences between tribals and non-tribals.
