Pulmonary tuberculosis - a health problem amongst Saharia tribe in Madhya Pradesh.

The information on tuberculosis (TB) situation amongst Saharia, one of the particularly vulnerable tribal groups (PVTGs) in Madhya Pradesh, is not available from Gwalior division of the s0 tate. Hence, this study was undertaken to estimate the prevalence of pulmonary tuberculosis (PTB) disease amongst them.A community based cross-sectional TB prevalence survey was undertaken among Saharia PVTG in Gwalior district of Madhya Pradesh. A random sample of villages predominated by Saharia tribe was selected from all the blocks in proportion to the size of Saharia population in each block of the district. All eligible individuals were questioned for chest symptoms relating to TB. Two sputum samples were collected from each of the eligible individuals, transported to the laboratory, and were examined by Ziehl-Neelsen(ZN) smear microscopy and solid media culture methods.Of the total 10,259 individuals eligible for screening, 9,653 (94.1%) were screened for symptoms. Overall prevalence of PTB was found to be 3294 per 100,000. The prevalence increased with age and the trend was significant ( p<0.001). The prevalence of TB was significantly higher amongst males (5497/100,000) as compared to females (1376/100,000) ( p<0.001).The study results provide vital information on the current situation of pulmonary TB disease among the Saharia tribal community in Gwalior district of Madhya Pradesh. In view of high PTB disease prevalence among this PVTG, there is an urgent need to improve and further intensify TB control measures in this area.
