Small for gestational age (SGA) babies are those whose birth weight lies below the 10th percentile for that gestational age. Low birth weight (LBW), is sometimes used to define a baby that weighs less than 5 lb 8 oz (2500 g) regardless of gestational age.
Low birth weight or LBW, as it is abbreviated, denotes birth weight of less than 2500 gm. In India, about 30 percent infants born are LBW. Nearly 75 percent neonatal deaths and 50 percent infant deaths occur among the low birth weight neonates.
