Keywords:

Background: Association between environmental factors and tu- berculosis infection assists in understanding the risk for tuberculo- sis infection in the community and planning appropriate preven- tive actions based on this risk. The study conducted to evaluate association between environmental factors & pulmonary tubercu- losis.
Materials & method: This was case control study carried out in tertiary care hospital & urban field practice area from July 2010 to November 2012. Total 150 cases, 150 hospital control & 150 com- munity controls were included in the study according to prede- fined inclusion and exclusion criteria. The study participants were interviewed and examined according to the preformed and pre- tested proforma in the respective OPDs.
Results: On univariate analysis, H/O contact with case of tubercu- losis H/O not having BCG scar, overcrowding, use of wood, coal and kerosene oil as cooking fuel and kutcha house were found to have significant association with pulmonary TB and odds ratio & p value for this were statistically significant (<0.05).
Conclusion: H/O contact with case of tuberculosis H/O not hav- ing BCG scar, overcrowding, use of wood, coal and kerosene oil as cooking fuel and kutcha house were found to have significant as- sociation with pulmonary TB.
