Methods: A case (registered under RNTCP) control study was undertaken with 41 cases and 82 controls. Results: Factors found to have significance according to binary logistic regression were low-birth weight (LBW) [Odd’s ratio=3.56],Malnutrition [Odd’s ratio=3.96], Passive smoking [Odd’s ratio=6.28] and exposure to fire-wood smoke [Odd’s ratio=6.91]. Conclusion: LBW, malnutrition, passive smoking and fire-wood smoke are the risk factors to be addressed to prevent pediatric TB.
